+# Node.js version support
+
+clean-css requires Node.js 4.0+ (tested on Linux, OS X, and Windows)
+
+# Install
+
+```
+npm install --save-dev clean-css
+```
+
+# Use
+
+```js
+var CleanCSS = require('clean-css');
+var input = 'a{font-weight:bold;}';
+var options = { /* options */ };
+var output = new CleanCSS(options).minify(input);
+```
+
+## Important: 4.0 breaking changes
+
+clean-css 4.0 introduces some breaking changes:
+
+* API and CLI interfaces are split, so API stays in this repository while CLI moves to [clean-css-cli](https://github.com/jakubpawlowicz/clean-css-cli);
+* `root`, `relativeTo`, and `target` options are replaced by a single `rebaseTo` option - this means that rebasing URLs and import inlining is much simpler but may not be (YMMV) as powerful as in 3.x;
+* `debug` option is gone as stats are always provided in output object under `stats` property;
+* `roundingPrecision` is disabled by default;
+* `roundingPrecision` applies to **all** units now, not only `px` as in 3.x;
+* `processImport` and `processImportFrom` are merged into `inline` option which defaults to `local`. Remote `@import` rules are **NOT** inlined by default anymore;
+* splits `inliner: { request: ..., timeout: ... }` option into `inlineRequest` and `inlineTimeout` options;
+* remote resources without a protocol, e.g. `//fonts.googleapis.com/css?family=Domine:700`, are not inlined anymore;
+* changes default Internet Explorer compatibility from 9+ to 10+, to revert the old default use `{ compatibility: 'ie9' }` flag;
+* renames `keepSpecialComments` to `specialComments`;
+* moves `roundingPrecision` and `specialComments` to level 1 optimizations options, see examples;
+* moves `mediaMerging`, `restructuring`, `semanticMerging`, and `shorthandCompacting` to level 2 optimizations options, see examples below;
+* renames `shorthandCompacting` option to `mergeIntoShorthands`;
+* level 1 optimizations are the new default, up to 3.x it was level 2;
+* `keepBreaks` option is replaced with `{ format: 'keep-breaks' }` to ease transition;
+* `sourceMap` option has to be a boolean from now on - to specify an input source map pass it a 2nd argument to `minify` method or via a hash instead;
+* `aggressiveMerging` option is removed as aggressive merging is replaced by smarter override merging.
+
+## What's new in version 4.1
+
+clean-css 4.1 introduces the following changes / features:
+
+* `inline: false` as an alias to `inline: ['none']`;
+* `multiplePseudoMerging` compatibility flag controlling merging of rules with multiple pseudo classes / elements;
+* `removeEmpty` flag in level 1 optimizations controlling removal of rules and nested blocks;
+* `removeEmpty` flag in level 2 optimizations controlling removal of rules and nested blocks;
+* `compatibility: { selectors: { mergeLimit: <number> } }` flag in compatibility settings controlling maximum number of selectors in a single rule;
+* `minify` method improved signature accepting a list of hashes for a predictable traversal;
+* `selectorsSortingMethod` level 1 optimization allows `false` or `'none'` for disabling selector sorting;
+* `fetch` option controlling a function for handling remote requests;
+* new `font` shorthand and `font-*` longhand optimizers;
+* removal of `optimizeFont` flag in level 1 optimizations due to new `font` shorthand optimizer;
+* `skipProperties` flag in level 2 optimizations controlling which properties won't be optimized;
+* new `animation` shorthand and `animation-*` longhand optimizers;
+* `removeUnusedAtRules` level 2 optimization controlling removal of unused `@counter-style`, `@font-face`, `@keyframes`, and `@namespace` at rules;
+* the [web interface](https://jakubpawlowicz.github.io/clean-css) gets an improved settings panel with "reset to defaults", instant option changes, and settings being persisted across sessions.
+
+## What's new in version 4.2
+
+clean-css 4.2 introduces the following changes / features:
+
+* Adds `process` method for compatibility with optimize-css-assets-webpack-plugin;
+* new `transition` property optimizer;
+* preserves any CSS content between `/* clean-css ignore:start */` and `/* clean-css ignore:end */` comments;
+* allows filtering based on selector in `transform` callback, see [example](#how-to-apply-arbitrary-transformations-to-css-properties);
+* adds configurable line breaks via `format: { breakWith: 'lf' }` option.
+
+## Constructor options
+
+clean-css constructor accepts a hash as a parameter with the following options available:
+
+* `compatibility` - controls compatibility mode used; defaults to `ie10+`; see [compatibility modes](#compatibility-modes) for examples;
+* `fetch` - controls a function for handling remote requests; see [fetch option](#fetch-option) for examples (since 4.1.0);
+* `format` - controls output CSS formatting; defaults to `false`; see [formatting options](#formatting-options) for examples;
+* `inline` - controls `@import` inlining rules; defaults to `'local'`; see [inlining options](#inlining-options) for examples;
+* `inlineRequest` - controls extra options for inlining remote `@import` rules, can be any of [HTTP(S) request options](https://nodejs.org/api/http.html#http_http_request_options_callback);
+* `inlineTimeout` - controls number of milliseconds after which inlining a remote `@import` fails; defaults to 5000;
+* `level` - controls optimization level used; defaults to `1`; see [optimization levels](#optimization-levels) for examples;
+* `rebase` - controls URL rebasing; defaults to `true`;
+* `rebaseTo` - controls a directory to which all URLs are rebased, most likely the directory under which the output file will live; defaults to the current directory;
+* `returnPromise` - controls whether `minify` method returns a Promise object or not; defaults to `false`; see [promise interface](#promise-interface) for examples;
+* `sourceMap` - controls whether an output source map is built; defaults to `false`;
+* `sourceMapInlineSources` - controls embedding sources inside a source map's `sourcesContent` field; defaults to false.
+
+## Compatibility modes
+
+There is a certain number of compatibility mode shortcuts, namely:
+
+* `new CleanCSS({ compatibility: '*' })` (default) - Internet Explorer 10+ compatibility mode
+* `new CleanCSS({ compatibility: 'ie9' })` - Internet Explorer 9+ compatibility mode
+* `new CleanCSS({ compatibility: 'ie8' })` - Internet Explorer 8+ compatibility mode
+* `new CleanCSS({ compatibility: 'ie7' })` - Internet Explorer 7+ compatibility mode
+
+Each of these modes is an alias to a [fine grained configuration](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/options/compatibility.js), with the following options available:
+
+```js
+new CleanCSS({
+ compatibility: {
+ colors: {
+ opacity: true // controls `rgba()` / `hsla()` color support
+ },
+ properties: {
+ backgroundClipMerging: true, // controls background-clip merging into shorthand
+ backgroundOriginMerging: true, // controls background-origin merging into shorthand
+ backgroundSizeMerging: true, // controls background-size merging into shorthand
+ colors: true, // controls color optimizations
+ ieBangHack: false, // controls keeping IE bang hack
+ ieFilters: false, // controls keeping IE `filter` / `-ms-filter`
+ iePrefixHack: false, // controls keeping IE prefix hack
+ ieSuffixHack: false, // controls keeping IE suffix hack
+ merging: true, // controls property merging based on understandability
+ shorterLengthUnits: false, // controls shortening pixel units into `pc`, `pt`, or `in` units
+ spaceAfterClosingBrace: true, // controls keeping space after closing brace - `url() no-repeat` into `url()no-repeat`
+ urlQuotes: false, // controls keeping quoting inside `url()`
+ zeroUnits: true // controls removal of units `0` value
+ },
+ selectors: {
+ adjacentSpace: false, // controls extra space before `nav` element
+ ie7Hack: true, // controls removal of IE7 selector hacks, e.g. `*+html...`
+ mergeablePseudoClasses: [':active', ...], // controls a whitelist of mergeable pseudo classes
+ mergeablePseudoElements: ['::after', ...], // controls a whitelist of mergeable pseudo elements
+ mergeLimit: 8191, // controls maximum number of selectors in a single rule (since 4.1.0)
+ multiplePseudoMerging: true // controls merging of rules with multiple pseudo classes / elements (since 4.1.0)
+ },
+ units: {
+ ch: true, // controls treating `ch` as a supported unit
+ in: true, // controls treating `in` as a supported unit
+ pc: true, // controls treating `pc` as a supported unit
+ pt: true, // controls treating `pt` as a supported unit
+ rem: true, // controls treating `rem` as a supported unit
+ vh: true, // controls treating `vh` as a supported unit
+ vm: true, // controls treating `vm` as a supported unit
+ vmax: true, // controls treating `vmax` as a supported unit
+ vmin: true // controls treating `vmin` as a supported unit
+ }
+ }
+})
+```
+
+You can also use a string when setting a compatibility mode, e.g.
+
+```js
+new CleanCSS({
+ compatibility: 'ie9,-properties.merging' // sets compatibility to IE9 mode with disabled property merging
+})
+```
+
+## Fetch option
+
+The `fetch` option accepts a function which handles remote resource fetching, e.g.
+
+```js
+var request = require('request');
+var source = '@import url(http://example.com/path/to/stylesheet.css);';
+new CleanCSS({
+ fetch: function (uri, inlineRequest, inlineTimeout, callback) {
+ request(uri, function (error, response, body) {
+ if (error) {
+ callback(error, null);
+ } else if (response && response.statusCode != 200) {
+ callback(response.statusCode, null);
+ } else {
+ callback(null, body);
+ }
+ });
+ }
+}).minify(source);
+```
+
+This option provides a convenient way of overriding the default fetching logic if it doesn't support a particular feature, say CONNECT proxies.
+
+Unless given, the default [loadRemoteResource](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/reader/load-remote-resource.js) logic is used.
+
+## Formatting options
+
+By default output CSS is formatted without any whitespace unless a `format` option is given.
+First of all there are two shorthands:
+
+```js
+new CleanCSS({
+ format: 'beautify' // formats output in a really nice way
+})
+```
+
+and
+
+```js
+new CleanCSS({
+ format: 'keep-breaks' // formats output the default way but adds line breaks for improved readability
+})
+```
+
+however `format` option also accept a fine-grained set of options:
+
+```js
+new CleanCSS({
+ format: {
+ breaks: { // controls where to insert breaks
+ afterAtRule: false, // controls if a line break comes after an at-rule; e.g. `@charset`; defaults to `false`
+ afterBlockBegins: false, // controls if a line break comes after a block begins; e.g. `@media`; defaults to `false`
+ afterBlockEnds: false, // controls if a line break comes after a block ends, defaults to `false`
+ afterComment: false, // controls if a line break comes after a comment; defaults to `false`
+ afterProperty: false, // controls if a line break comes after a property; defaults to `false`
+ afterRuleBegins: false, // controls if a line break comes after a rule begins; defaults to `false`
+ afterRuleEnds: false, // controls if a line break comes after a rule ends; defaults to `false`
+ beforeBlockEnds: false, // controls if a line break comes before a block ends; defaults to `false`
+ betweenSelectors: false // controls if a line break comes between selectors; defaults to `false`
+ },
+ breakWith: '\n', // controls the new line character, can be `'\r\n'` or `'\n'` (aliased as `'windows'` and `'unix'` or `'crlf'` and `'lf'`); defaults to system one, so former on Windows and latter on Unix
+ indentBy: 0, // controls number of characters to indent with; defaults to `0`
+ indentWith: 'space', // controls a character to indent with, can be `'space'` or `'tab'`; defaults to `'space'`
+ spaces: { // controls where to insert spaces
+ aroundSelectorRelation: false, // controls if spaces come around selector relations; e.g. `div > a`; defaults to `false`
+ beforeBlockBegins: false, // controls if a space comes before a block begins; e.g. `.block {`; defaults to `false`
+ beforeValue: false // controls if a space comes before a value; e.g. `width: 1rem`; defaults to `false`
+ },
+ wrapAt: false // controls maximum line length; defaults to `false`
+ }
+})
+```
+
+## Inlining options
+
+`inline` option whitelists which `@import` rules will be processed, e.g.
+
+```js
+new CleanCSS({
+ inline: ['local'] // default; enables local inlining only
+})
+```
+
+```js
+new CleanCSS({
+ inline: ['none'] // disables all inlining
+})
+```
+
+```js
+// introduced in clean-css 4.1.0
+
+new CleanCSS({
+ inline: false // disables all inlining (alias to `['none']`)
+})
+```
+
+```js
+new CleanCSS({
+ inline: ['all'] // enables all inlining, same as ['local', 'remote']
+})
+```
+
+```js
+new CleanCSS({
+ inline: ['local', 'mydomain.example.com'] // enables local inlining plus given remote source
+})
+```
+
+```js
+new CleanCSS({
+ inline: ['local', 'remote', '!fonts.googleapis.com'] // enables all inlining but from given remote source
+})
+```
+
+## Optimization levels
+
+The `level` option can be either `0`, `1` (default), or `2`, e.g.
+
+```js
+new CleanCSS({
+ level: 2
+})
+```
+
+or a fine-grained configuration given via a hash.
+
+Please note that level 1 optimization options are generally safe while level 2 optimizations should be safe for most users.
+
+### Level 0 optimizations
+
+Level 0 optimizations simply means "no optimizations". Use it when you'd like to inline imports and / or rebase URLs but skip everything else.
+
+### Level 1 optimizations
+
+Level 1 optimizations (default) operate on single properties only, e.g. can remove units when not required, turn rgb colors to a shorter hex representation, remove comments, etc
+
+Here is a full list of available options:
+
+```js
+new CleanCSS({
+ level: {
+ 1: {
+ cleanupCharsets: true, // controls `@charset` moving to the front of a stylesheet; defaults to `true`
+ normalizeUrls: true, // controls URL normalization; defaults to `true`
+ optimizeBackground: true, // controls `background` property optimizations; defaults to `true`
+ optimizeBorderRadius: true, // controls `border-radius` property optimizations; defaults to `true`
+ optimizeFilter: true, // controls `filter` property optimizations; defaults to `true`
+ optimizeFont: true, // controls `font` property optimizations; defaults to `true`
+ optimizeFontWeight: true, // controls `font-weight` property optimizations; defaults to `true`
+ optimizeOutline: true, // controls `outline` property optimizations; defaults to `true`
+ removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
+ removeNegativePaddings: true, // controls removing negative paddings; defaults to `true`
+ removeQuotes: true, // controls removing quotes when unnecessary; defaults to `true`
+ removeWhitespace: true, // controls removing unused whitespace; defaults to `true`
+ replaceMultipleZeros: true, // contols removing redundant zeros; defaults to `true`
+ replaceTimeUnits: true, // controls replacing time units with shorter values; defaults to `true`
+ replaceZeroUnits: true, // controls replacing zero values with units; defaults to `true`
+ roundingPrecision: false, // rounds pixel values to `N` decimal places; `false` disables rounding; defaults to `false`
+ selectorsSortingMethod: 'standard', // denotes selector sorting method; can be `'natural'` or `'standard'`, `'none'`, or false (the last two since 4.1.0); defaults to `'standard'`
+ specialComments: 'all', // denotes a number of /*! ... */ comments preserved; defaults to `all`
+ tidyAtRules: true, // controls at-rules (e.g. `@charset`, `@import`) optimizing; defaults to `true`
+ tidyBlockScopes: true, // controls block scopes (e.g. `@media`) optimizing; defaults to `true`
+ tidySelectors: true, // controls selectors optimizing; defaults to `true`,
+ semicolonAfterLastProperty: false, // controls removing trailing semicolons in rule; defaults to `false` - means remove
+ transform: function () {} // defines a callback for fine-grained property optimization; defaults to no-op
+ }
+ }
+});
+```
+
+There is an `all` shortcut for toggling all options at the same time, e.g.
+
+```js
+new CleanCSS({
+ level: {
+ 1: {
+ all: false, // set all values to `false`
+ tidySelectors: true // turns on optimizing selectors
+ }
+ }
+});
+```
+
+### Level 2 optimizations
+
+Level 2 optimizations operate at rules or multiple properties level, e.g. can remove duplicate rules, remove properties redefined further down a stylesheet, or restructure rules by moving them around.
+
+Please note that if level 2 optimizations are turned on then, unless explicitely disabled, level 1 optimizations are applied as well.
+
+Here is a full list of available options:
+
+```js
+new CleanCSS({
+ level: {
+ 2: {
+ mergeAdjacentRules: true, // controls adjacent rules merging; defaults to true
+ mergeIntoShorthands: true, // controls merging properties into shorthands; defaults to true
+ mergeMedia: true, // controls `@media` merging; defaults to true
+ mergeNonAdjacentRules: true, // controls non-adjacent rule merging; defaults to true
+ mergeSemantically: false, // controls semantic merging; defaults to false
+ overrideProperties: true, // controls property overriding based on understandability; defaults to true
+ removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
+ reduceNonAdjacentRules: true, // controls non-adjacent rule reducing; defaults to true
+ removeDuplicateFontRules: true, // controls duplicate `@font-face` removing; defaults to true
+ removeDuplicateMediaBlocks: true, // controls duplicate `@media` removing; defaults to true
+ removeDuplicateRules: true, // controls duplicate rules removing; defaults to true
+ removeUnusedAtRules: false, // controls unused at rule removing; defaults to false (available since 4.1.0)
+ restructureRules: false, // controls rule restructuring; defaults to false
+ skipProperties: [] // controls which properties won't be optimized, defaults to `[]` which means all will be optimized (since 4.1.0)
+ }
+ }
+});
+```
+
+There is an `all` shortcut for toggling all options at the same time, e.g.
+
+```js
+new CleanCSS({
+ level: {
+ 2: {
+ all: false, // sets all values to `false`
+ removeDuplicateRules: true // turns on removing duplicate rules
+ }
+ }
+});
+```
+
+## Minify method
+
+Once configured clean-css provides a `minify` method to optimize a given CSS, e.g.
+
+```js
+var output = new CleanCSS(options).minify(source);
+```
+
+The output of the `minify` method is a hash with following fields:
+
+```js
+console.log(output.styles); // optimized output CSS as a string
+console.log(output.sourceMap); // output source map if requested with `sourceMap` option
+console.log(output.errors); // a list of errors raised
+console.log(output.warnings); // a list of warnings raised
+console.log(output.stats.originalSize); // original content size after import inlining
+console.log(output.stats.minifiedSize); // optimized content size
+console.log(output.stats.timeSpent); // time spent on optimizations in milliseconds
+console.log(output.stats.efficiency); // `(originalSize - minifiedSize) / originalSize`, e.g. 0.25 if size is reduced from 100 bytes to 75 bytes
+```
+
+The `minify` method also accepts an input source map, e.g.
+
+```js
+var output = new CleanCSS(options).minify(source, inputSourceMap);
+```
+
+or a callback invoked when optimizations are finished, e.g.
+
+```js
+new CleanCSS(options).minify(source, function (error, output) {
+ // `output` is the same as in the synchronous call above
+});
+```
+
+## Promise interface
+
+If you prefer clean-css to return a Promise object then you need to explicitely ask for it, e.g.
+
+```js
+new CleanCSS({ returnPromise: true })
+ .minify(source)
+ .then(function (output) { console.log(output.styles); })
+ .catch(function (error) { // deal with errors });
+```
+
+## CLI utility
+
+Clean-css has an associated command line utility that can be installed separately using `npm install clean-css-cli`. For more detailed information, please visit https://github.com/jakubpawlowicz/clean-css-cli.
+
+# FAQ
+
+## How to optimize multiple files?
+
+It can be done either by passing an array of paths, or, when sources are already available, a hash or an array of hashes:
+
+```js
+new CleanCSS().minify(['path/to/file/one', 'path/to/file/two']);
+```
+
+```js
+new CleanCSS().minify({
+ 'path/to/file/one': {
+ styles: 'contents of file one'
+ },
+ 'path/to/file/two': {
+ styles: 'contents of file two'
+ }
+});
+```
+
+```js
+new CleanCSS().minify([
+ {'path/to/file/one': {styles: 'contents of file one'}},
+ {'path/to/file/two': {styles: 'contents of file two'}}
+]);
+```
+
+Passing an array of hashes allows you to explicitly specify the order in which the input files are concatenated. Whereas when you use a single hash the order is determined by the [traversal order of object properties](http://2ality.com/2015/10/property-traversal-order-es6.html) - available since 4.1.0.
+
+Important note - any `@import` rules already present in the hash will be resolved in memory.
+
+## How to process remote `@import`s correctly?
+
+In order to inline remote `@import` statements you need to provide a callback to minify method as fetching remote assets is an asynchronous operation, e.g.:
+
+```js
+var source = '@import url(http://example.com/path/to/remote/styles);';
+new CleanCSS({ inline: ['remote'] }).minify(source, function (error, output) {
+ // output.styles
+});
+```
+
+If you don't provide a callback, then remote `@import`s will be left as is.
+
+## How to apply arbitrary transformations to CSS properties?
+
+If clean-css doesn't perform a particular property optimization, you can use `transform` callback to apply it:
+
+```js
+var source = '.block{background-image:url(/path/to/image.png)}';
+var output = new CleanCSS({
+ level: {
+ 1: {
+ transform: function (propertyName, propertyValue, selector /* `selector` available since 4.2.0-pre */) {
+ if (propertyName == 'background-image' && propertyValue.indexOf('/path/to') > -1) {
+ return propertyValue.replace('/path/to', '../valid/path/to');
+ }
+ }
+ }
+ }
+}).minify(source);
+
+console.log(output.styles); # => .block{background-image:url(../valid/path/to/image.png)}
+```
+
+Note: returning `false` from `transform` callback will drop a property.
+
+## How to specify a custom rounding precision?
+
+The level 1 `roundingPrecision` optimization option accept a string with per-unit rounding precision settings, e.g.
+
+```js
+new CleanCSS({
+ level: {
+ 1: {
+ roundingPrecision: 'all=3,px=5'
+ }
+ }
+}).minify(source)
+```
+
+which sets all units rounding precision to 3 digits except `px` unit precision of 5 digits.
+
+## How to keep a CSS fragment intact?
+
+Note: available in the current master, to be released in 4.2.0.
+
+Wrap the CSS fragment in special comments which instruct clean-css to preserve it, e.g.
+
+```css
+.block-1 {
+ color: red
+}
+/* clean-css ignore:start */
+.block-special {
+ color: transparent
+}
+/* clean-css ignore:end */
+.block-2 {
+ margin: 0
+}
+```
+
+Optimizing this CSS will result in the following output:
+
+```css
+.block-1{color:red}
+.block-special {
+ color: transparent
+}
+.block-2{margin:0}
+```
+
+## How to preserve a comment block?
+
+Use the `/*!` notation instead of the standard one `/*`:
+
+```css
+/*!
+ Important comments included in optimized output.
+*/
+```
+
+## How to rebase relative image URLs?
+
+clean-css will handle it automatically for you in the following cases:
+
+* when full paths to input files are passed in as options;
+* when correct paths are passed in via a hash;
+* when `rebaseTo` is used with any of above two.
+
+## How to work with source maps?
+
+To generate a source map, use `sourceMap: true` option, e.g.:
+
+```js
+new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
+ .minify(source, function (error, output) {
+ // access output.sourceMap for SourceMapGenerator object
+ // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
+});
+```
+
+You can also pass an input source map directly as a 2nd argument to `minify` method:
+
+```js
+new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
+ .minify(source, inputSourceMap, function (error, output) {
+ // access output.sourceMap to access SourceMapGenerator object
+ // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
+});
+```
+
+or even multiple input source maps at once:
+
+```js
+new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory }).minify({
+ 'path/to/source/1': {
+ styles: '...styles...',
+ sourceMap: '...source-map...'
+ },
+ 'path/to/source/2': {
+ styles: '...styles...',
+ sourceMap: '...source-map...'
+ }
+}, function (error, output) {
+ // access output.sourceMap as above
+});
+```
+
+## How to apply level 1 & 2 optimizations at the same time?
+
+Using the hash configuration specifying both optimization levels, e.g.
+
+```js
+new CleanCSS({
+ level: {
+ 1: {
+ all: true,
+ normalizeUrls: false
+ },
+ 2: {
+ restructureRules: true
+ }
+ }
+})
+```
+
+will apply level 1 optimizations, except url normalization, and default level 2 optimizations with rule restructuring.
+
+## What level 2 optimizations do?
+
+All level 2 optimizations are dispatched [here](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/optimizer/level-2/optimize.js#L67), and this is what they do:
+
+* `recursivelyOptimizeBlocks` - does all the following operations on a nested block, like `@media` or `@keyframe`;
+* `recursivelyOptimizeProperties` - optimizes properties in rulesets and flat at-rules, like @font-face, by splitting them into components (e.g. `margin` into `margin-(bottom|left|right|top)`), optimizing, and restoring them back. You may want to use `mergeIntoShorthands` option to control whether you want to turn multiple components into shorthands;
+* `removeDuplicates` - gets rid of duplicate rulesets with exactly the same set of properties, e.g. when including a Sass / Less partial twice for no good reason;
+* `mergeAdjacent` - merges adjacent rulesets with the same selector or rules;
+* `reduceNonAdjacent` - identifies which properties are overridden in same-selector non-adjacent rulesets, and removes them;
+* `mergeNonAdjacentBySelector` - identifies same-selector non-adjacent rulesets which can be moved (!) to be merged, requires all intermediate rulesets to not redefine the moved properties, or if redefined to have the same value;
+* `mergeNonAdjacentByBody` - same as the one above but for same-selector non-adjacent rulesets;
+* `restructure` - tries to reorganize different-selector different-rules rulesets so they take less space, e.g. `.one{padding:0}.two{margin:0}.one{margin-bottom:3px}` into `.two{margin:0}.one{padding:0;margin-bottom:3px}`;
+* `removeDuplicateFontAtRules` - removes duplicated `@font-face` rules;
+* `removeDuplicateMediaQueries` - removes duplicated `@media` nested blocks;
+* `mergeMediaQueries` - merges non-adjacent `@media` at-rules by the same rules as `mergeNonAdjacentBy*` above;
+

+// Extend this object in order to add support for more properties in the optimizer.
+//
+// Each key in this object represents a CSS property and should be an object.
+// Such an object contains properties that describe how the represented CSS property should be handled.
+// Possible options:
+//
+// * components: array (Only specify for shorthand properties.)
+// Contains the names of the granular properties this shorthand compacts.
+//
+// * canOverride: function
+// Returns whether two tokens of this property can be merged with each other.
+// This property has no meaning for shorthands.
+//
+// * defaultValue: string
+// Specifies the default value of the property according to the CSS standard.
+// For shorthand, this is used when every component is set to its default value, therefore it should be the shortest possible default value of all the components.
+//
+// * shortestValue: string
+// Specifies the shortest possible value the property can possibly have.
+// (Falls back to defaultValue if unspecified.)
+//
+// * breakUp: function (Only specify for shorthand properties.)
+// Breaks the shorthand up to its components.
+//
+// * restore: function (Only specify for shorthand properties.)
+// Puts the shorthand together from its components.

+[](https://david-dm.org/kangax/html-minifier)
+
+[HTMLMinifier](https://kangax.github.io/html-minifier/) is a highly **configurable**, **well-tested**, JavaScript-based HTML minifier.
+
+See [corresponding blog post](http://perfectionkills.com/experimenting-with-html-minifier/) for all the gory details of [how it works](http://perfectionkills.com/experimenting-with-html-minifier/#how_it_works), [description of each option](http://perfectionkills.com/experimenting-with-html-minifier/#options), [testing results](http://perfectionkills.com/experimenting-with-html-minifier/#field_testing) and [conclusions](http://perfectionkills.com/experimenting-with-html-minifier/#cost_and_benefits).
+
+[Test suite is available online](https://kangax.github.io/html-minifier/tests/).
+
+Also see corresponding [Ruby wrapper](https://github.com/stereobooster/html_minifier), and for Node.js, [Grunt plugin](https://github.com/gruntjs/grunt-contrib-htmlmin), [Gulp module](https://github.com/jonschlinkert/gulp-htmlmin), [Koa middleware wrapper](https://github.com/koajs/html-minifier) and [Express middleware wrapper](https://github.com/melonmanchan/express-minify-html).
+
+For lint-like capabilities take a look at [HTMLLint](https://github.com/kangax/html-lint).

+
+### Sorting attributes / style classes
+
+Minifier options like `sortAttributes` and `sortClassName` won't impact the plain-text size of the output. However, they form long repetitive chains of characters that should improve compression ratio of gzip used in HTTP compression.
+
+## Special cases
+
+### Ignoring chunks of markup
+
+If you have chunks of markup you would like preserved, you can wrap them `<!-- htmlmin:ignore -->`.
+
+### Preserving SVG tags
+
+SVG tags are automatically recognized, and when they are minified, both case-sensitivity and closing-slashes are preserved, regardless of the minification settings used for the rest of the file.
+
+### Working with invalid markup
+
+HTMLMinifier **can't work with invalid or partial chunks of markup**. This is because it parses markup into a tree structure, then modifies it (removing anything that was specified for removal, ignoring anything that was specified to be ignored, etc.), then it creates a markup out of that tree and returns it.
+
+Input markup (e.g. `<p id="">foo`)
+
+↓
+
+Internal representation of markup in a form of tree (e.g. `{ tag: "p", attr: "id", children: ["foo"] }`)
+
+↓
+
+Transformation of internal representation (e.g. removal of `id` attribute)
+
+↓
+
+Output of resulting markup (e.g. `<p>foo</p>`)
+
+HTMLMinifier can't know that original markup was only half of the tree; it does its best to try to parse it as a full tree and it loses information about tree being malformed or partial in the beginning. As a result, it can't create a partial/malformed tree at the time of the output.
+
+## Installation Instructions
+
+From NPM for use as a command line app:
+
+```shell
+npm install html-minifier -g
+```
+
+From NPM for programmatic use:
+
+```shell
+npm install html-minifier
+```
+
+From Git:
+
+```shell
+git clone git://github.com/kangax/html-minifier.git
+cd html-minifier
+npm link .
+```
+
+## Usage
+
+Note that almost all options are disabled by default. For command line usage please see `html-minifier --help` for a list of available options. Experiment and find what works best for you and your project.
+
+* **Sample command line:** ``html-minifier --collapse-whitespace --remove-comments --remove-optional-tags --remove-redundant-attributes --remove-script-type-attributes --remove-tag-whitespace --use-short-doctype --minify-css true --minify-js true``
+
+### Node.js
+
+```js
+var minify = require('html-minifier').minify;
+var result = minify('<p title="blah" id="moo">foo</p>', {
+ removeAttributeQuotes: true
+});
+result; // '<p title=blah id=moo>foo</p>'
+```
+
+## Running benchmarks
+
+Benchmarks for minified HTML:
+
+```shell
+node benchmark.js
+```

+# Lower Case
+
+[![NPM version][npm-image]][npm-url]
+[![NPM downloads][downloads-image]][downloads-url]
+[![Build status][travis-image]][travis-url]
+[![Test coverage][coveralls-image]][coveralls-url]
+
+Lower case a string.
+
+Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a `toString` property, numbers and booleans. Empty values (`null` and `undefined`) will result in an empty string.
+
+## Installation
+
+```
+npm install lower-case --save
+```
+
+## Usage
+
+```js
+var lowerCase = require('lower-case')
+
+lowerCase(null) //=> ""
+lowerCase('STRING') //=> "string"
+lowerCase('STRING', 'tr') //=> "strıng"
+
+lowerCase({ toString: function () { return 'TEST' } }) //=> "test"
+```

+# minify-html-literals
+
+_Minify HTML markup inside JavaScript template literal strings._
+
+[](https://www.npmjs.com/package/minify-html-literals)
+[](https://travis-ci.com/asyncLiz/minify-html-literals)
+[](https://coveralls.io/github/asyncLiz/minify-html-literals?branch=master)
+
+## Why?
+
+Template literals are often used in JavaScript to write HTML and CSS markup (ex. [lit-html](https://www.npmjs.com/package/lit-html)). This library allows a developer to minify markup that is normally ignored by JavaScript minifiers.
+
+## Usage
+
+```js
+import { minifyHTMLLiterals } from 'minify-html-literals';
+// const minifyHTMLLiterals = require('minify-html-literals').minifyHTMLLiterals
+
+const result = minifyHTMLLiterals(
+ `function render(title, items) {
+ return html\`
+ <style>
+ .heading {
+ color: blue;
+ }
+ </style>
+ <h1 class="heading">\${title}</h1>
+ <ul>
+ \${items.map(item => {
+ return getHTML()\`
+ <li>\${item}</li>
+ \`;
+ })}
+ </ul>
+ \`;
+ }`,
+ {
+ fileName: 'render.js'
+ }
+);
+
+console.log(result.code);
+// function render(title, items) {
+// return html`<style>.heading{color:#00f}</style><h1 class=heading>${title}</h1><ul>${items.map(item => {
+// return getHTML()`<li>${item}</li>`;
+// })}</ul>`;
+// }
+
+console.log(result.map);
+// {
+// "version": 3,
+// "file": "render.js.map",
+// "sources": ["render.js"],
+// "sourcesContent": [null],
+// "names": [],
+// "mappings": "AAAA;gBACgB,qDAMU,QAAQ,SAE1B;2BACmB,IACX,OAAO,KACb;WACC,KAEP;"
+// }

+### ES5 Transpiling Warning
+
+Be sure to minify template literals _before_ transpiling to ES5. Otherwise, the API will not be able to find any template literal (`` `${}` ``) strings.
+
+## Supported Source Syntax
+
+- JavaScript
+- TypeScript
+
+## Options
+
+### Basic
+
+The following options are common to typical use cases.
+
+| Property | Type | Default | Description |
+| --------------------------- | -------------------------------------------------------------------------------------------- | ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `fileName` | string | | _Required._ The name of the file, used for syntax parsing and source maps. |
+| `minifyOptions?` | [html-minifier options](https://www.npmjs.com/package/html-minifier#options-quick-reference) | `defaultMinifyOptions` | Defaults to production-ready minification. |
+| `minifyOptions?.minifyCSS?` | [clean-css options](https://www.npmjs.com/package/clean-css#constructor-options) | `defaultMinifyCSSOptions` | Uses clean-css defaults. |
+| `shouldMinify?` | function | `defaultShouldMinify` | A function that determines whether or not an HTML template should be minified. Defaults to minify all tagged templates whose tag name contains "html" (case insensitive). |
+| `shouldMinifyCSS?` | function | `defaultShouldMinifyCSS` | A function that determines whether or not a CSS template should be minified. Defaults to minify all tagged templates whose tag name contains "css" (case insensitive). |
+
+### Advanced
+
+All aspects of the API are exposed and customizable. The following options will not typically be used unless you need to change how a certain aspect of the API handles a use case.
+
+| Property | Type | Default | Description |
+| ----------------------- | ------------------------------------------------------------------------- | -------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `generateSourceMap?` | boolean or `(ms: MagicString, fileName: string) => SourceMap | undefined` | `defaultGenerateSourceMap` | Set to `false` to disable source maps, or a custom function to control how source maps are generated from a `MagicString` instance. |
+| `strategy?` | object | `defaultStrategy` | An object with methods defining how to minify HTML. The default strategy uses [html-minifier](https://www.npmjs.com/package/html-minifier). |
+| `validate?` | boolean or object | `defaultValidation` | Set to `false` to disable strategy validation checks, or to a custom set of validation functions. This is only useful when implementing a custom strategy. |
+| `parseLiterals?` | function | [parse-literals](https://www.npmjs.com/package/parse-literals) | Override the function used to parse template literals from a source string. |
+| `parseLiteralsOptions?` | object | | Additional options to pass to `parseLiterals()` |
+| `MagicString?` | function | [MagicString](https://www.npmjs.com/package/magic-string) | Override the MagicString-like constructor to use for manipulating the source string and generating source maps. |
+
+## Customization Examples
+
+### Minify non-tagged templates
+
+> This is particularly useful for libraries that define templates without using tags, such as Polymer's `<dom-module>`.
+
+```js
+import { minifyHTMLLiterals, defaultShouldMinify } from 'minify-html-literals';
+
+minifyHTMLLiterals(
+ `
+ template.innerHTML = \`
+ <dom-module id="custom-styles">
+ <style>
+ html {
+ --custom-color: blue;
+ }
+ </style>
+ </dom-module>
+ \`;
+ `,
+ {
+ fileName: 'render.js',
+ shouldMinify(template) {
+ return (
+ defaultShouldMinify(template) ||
+ template.parts.some(part => {
+ return part.text.includes('<dom-module>');
+ })
+ );
+ }
+ }
+);
+```
+
+### Do not minify CSS
+
+```js
+import { minifyHTMLLiterals, defaultMinifyOptions } from 'minify-html-literals';
+
+minifyHTMLLiterals(source, {
+ fileName: 'render.js',
+ minifyOptions: {
+ ...defaultMinifyOptions,
+ minifyCSS: false
+ },
+ shouldMinifyCSS: () => false
+});
+```
+
+### Modify generated SourceMap
+
+```js
+minifyHTMLLiterals(source, {
+ fileName: 'render.js',
+ generateSourceMap(ms, fileName) {
+ return ms.generateMap({
+ file: `${fileName}-converted.map`, // change file name
+ source: fileName,
+ includeContent: true // include source contents
+ });
+ }
+});
+```

+# No Case
+
+[![NPM version][npm-image]][npm-url]
+[![NPM downloads][downloads-image]][downloads-url]
+[![Build status][travis-image]][travis-url]
+[![Test coverage][coveralls-image]][coveralls-url]
+[](https://greenkeeper.io/)
+
+Transform a string to lower space cased. Optional locale and replacement character supported.
+
+Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a `toString` property, numbers and booleans. Empty values (`null` and `undefined`) will result in an empty string.
+
+## Installation
+
+```
+npm install no-case --save
+```
+
+## Usage
+
+```javascript
+var noCase = require('no-case')
+
+noCase(null) //=> ""
+noCase('string') //=> "string"
+noCase('dot.case') //=> "dot case"
+noCase('camelCase') //=> "camel case"
+noCase('Beyoncé Knowles') //=> "beyoncé knowles"
+
+noCase('A STRING', 'tr') //=> "a strıng"
+
+noCase('HELLO WORLD!', null, '_') //=> "hello_world"
+```

+# Param Case
+
+[![NPM version][npm-image]][npm-url]
+[![NPM downloads][downloads-image]][downloads-url]
+[![Build status][travis-image]][travis-url]
+[![Test coverage][coveralls-image]][coveralls-url]
+
+Param case a string.
+
+Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a `toString` property, numbers and booleans. Empty values (`null` and `undefined`) will result in an empty string.
+
+## Installation
+
+```
+npm install param-case --save
+```
+
+## Usage
+
+```javascript
+var paramCase = require('param-case')
+
+paramCase('string') //=> "string"
+paramCase('camelCase') //=> "camel-case"
+paramCase('sentence case') //=> "sentence-case"
+
+paramCase('MY STRING', 'tr') //=> "my-strıng"
+```

+Template literals are often used in JavaScript for HTML and CSS. This library allows developers to extract the strings from the literals for post processing, such as minifying or linting.
+
+## Usage
+
+```js
+import * as pl from 'parse-literals';
+// const pl = require('parse-literals');
+
+const templates = pl.parseLiterals(`
+ render() {
+ return html\`
+ <h1>\${"Hello World"}</h1>
+ \`;
+ }
+`);
+
+console.log(templates);
+// [
+// {
+// "tag": "html",
+// "parts": [
+// {
+// "text": "\n <h1>",
+// "start": 30,
+// "end": 41
+// },
+// {
+// "text": "</h1>\n ",
+// "start": 57,
+// "end": 67
+// }
+// ]
+// }
+// ]
+```

+
+> Minify URLs by converting them from absolute to relative.
+
+If you were to use this library on a website like `http://example.com/dir1/dir1-1/`, you would get results such as:
+
+| Before | After |
+| :------------------------------------------ | :----------------------------------- |
+| `http://example.com/dir1/dir1-2/index.html` | `../dir1-2/` |
+| `http://example.com/dir2/dir2-1/` | `/dir2/dir2-1/` |
+| `http://example.com/dir1/dir1-1/` | ` ` |
+| `https://example.com/dir1/dir1-1/` | `https://example.com/dir1/dir1-1/` |
+| `http://google.com:80/dir/` | `//google.com/dir/` |
+| `../../../../../../../../#anchor` | `/#anchor` |
+
+**All string parsing.** *No* directory browsing. It is thoroughly tested, very fast and lightweight with zero external dependencies.
+
+## Getting Started
+
+This utility requires [Node.js](http://nodejs.org/) `>= 0.10`. To install, type this at the command line:
+```
+npm install relateurl --save-dev
+```
+
+### Options
+
+#### options.defaultPorts
+Type: `Object`
+Default value: `{ftp:21, http:80, https:443}`
+
+Extend the list with any ports you need. Any URLs containing these default ports will have them removed. Example: `http://example.com:80/` will become `http://example.com/`.
+
+#### options.directoryIndexes
+Type: `Array`
+Default value: `["index.html"]`
+
+Extend the list with any resources you need. Works with [`options.removeDirectoryIndexes`](#options.removeDirectoryIndexes).
+
+#### options.ignore_www
+Type: `Boolean`
+Default value: `false`
+
+This will, for example, consider any domains containing `http://www.example.com/` to be related to any that contain `http://example.com/`.
+
+#### options.output
+Type: constant or `String`
+Choices: `RelateUrl.ABSOLUTE`,`RelateUrl.PATH_RELATIVE`,`RelateUrl.ROOT_RELATIVE`,`RelateUrl.SHORTEST`
+Choices: `"absolute"`,`"pathRelative"`,`"rootRelative"`,`"shortest"`
+Default value: `RelateUrl.SHORTEST`
+
+`RelateUrl.ABSOLUTE` will produce an absolute URL. Overrides [`options.schemeRelative`](#options.schemeRelative) with a value of `false`.
+`RelateUrl.PATH_RELATIVE` will produce something like `../child-of-parent/etc/`.
+`RelateUrl.ROOT_RELATIVE` will produce something like `/child-of-root/etc/`.
+`RelateUrl.SHORTEST` will choose whichever is shortest between root- and path-relative.
+
+#### options.rejectedSchemes
+Type: `Array`
+Default value: `["data","javascript","mailto"]`
+
+Extend the list with any additional schemes. Example: `javascript:something` will not be modified.
+
+#### options.removeAuth
+Type: `Boolean`
+Default value: `false`
+
+Remove user authentication information from the output URL.
+
+#### options.removeDirectoryIndexes
+Type: `Boolean`
+Default value: `true`
+
+Remove any resources that match any found in [`options.directoryIndexes`](#options.directoryIndexes).
+
+#### options.removeEmptyQueries
+Type: `Boolean`
+Default value: `false`
+
+Remove empty query variables. Example: `http://domain.com/?var1&var2=&var3=asdf` will become `http://domain.com/?var3=adsf`. This does not apply to unrelated URLs (with other protocols, auths, hosts and/or ports).
+
+#### options.removeRootTrailingSlash
+Type: `Boolean`
+Default value: `true`
+
+Remove trailing slashes from root paths. Example: `http://domain.com/?var` will become `http://domain.com?var` while `http://domain.com/dir/?var` will not be modified.
+
+#### options.schemeRelative
+Type: `Boolean`
+Default value: `true`
+
+Output URLs relative to the scheme. Example: `http://example.com/` will become `//example.com/`.
+
+#### options.site
+Type: `String`
+Default value: `undefined`
+
+An options-based version of the [`from`](#examples) argument. If both are specified, `from` takes priority.
+
+#### options.slashesDenoteHost
+Type: `Boolean`
+Default value: `true`
+
+Passed to Node's [`url.parse`](http://nodejs.org/api/url.html#url_url_parse_urlstr_parsequerystring_slashesdenotehost).
+
+### Examples
+This library can be used as a [function for single-use](#single-instance) or as a [class for multiple conversions](#reusable-instances).
+
+Upon successful conversion, a `String` will be returned. If an issue is encountered while parsing `from`, an error will be thrown.
+
+#### Single Instance
+```js
+var RelateUrl = require("relateurl");
+
+var result = RelateUrl.relate(from, to, options);
+```
+
+#### Reusable Instances
+```js
+var RelateUrl = require("relateurl");
+
+var instance = new RelateUrl(from, options);
+
+var result1 = instance.relate(to1);
+var result2 = instance.relate(to2, customOptions);
+var result3 = instance.relate(to3);
+```

+To aid in further minifying HTML, mainly for the purpose of faster page loads and SEO. It's been integrated into [HTMLMinifier](https://github.com/kangax/html-minifier).
+
+2. **Why not just use Node's `url.parse`, `url.resolve` and `path.relative`?**
+`url.parse` *is* used, but `url.resolve` and `path.relative` are both slower and less powerful than this library.
+
+
+## Release History
+* 0.2.7 Node v6 support
+* 0.2.6 minor enhancements
+* 0.2.5 added `options.removeRootTrailingSlash`
+* 0.2.4 added `options.site`
+* 0.2.3 added browserify npm-script
+* 0.2.2 removed task runner
+* 0.2.1 shorten resource- and query-relative URLs, test variations list with other site URLs
+* 0.2.0 code cleanup, `options.removeEmptyQueries=true` only applied to unrelated URLs
+* 0.1.0 initial release
+
+
+## Roadmap
+* 0.2.8 check if queries are the same, regardless of param order
+* 0.2.8 possible [scheme exclusions](http://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml) such as `tel:`
+* 0.2.8 decipher and return invalid input (special cases) to complete test suite
+* 0.3.0 test `options.slashesDenoteHost=false`, add something like `options.externalDirectoryIndexes=[]` for external sites

+# rollup-plugin-minify-html-template-literals
+
+> Minifies HTML template literal strings
+
+[](https://www.npmjs.com/package/rollup-plugin-minify-html-template-literals)
+[](https://travis-ci.com/github/exuanbo/rollup-plugin-minify-html-template-literals)
+[](https://david-dm.org/exuanbo/rollup-plugin-minify-html-template-literals)
+[](https://github.com/exuanbo/rollup-plugin-minify-html-template-literals/blob/master/LICENSE)
+
+Uses [minify-html-literals](https://www.npmjs.com/package/minify-html-literals) to minify HTML and CSS markup inside JavaScript template literal strings.
+
+This plugin supports Rollup v2.
+
+## Install
+
+```bash
+npm install --save-dev rollup-plugin-minify-html-template-literals
+```
+
+## Usage
+
+```js
+import minifyHTML from 'rollup-plugin-minify-html-template-literals'
+import babel from '@rollup/plugin-babel'
+import { terser } from 'rollup-plugin-terser'
+
+export default {
+ input: 'index.js',
+ output: { file: 'dist/index.js' },
+ plugins: [
+ minifyHTML(),
+ // Order this plugin before other transpilers and minifiers
+ babel(),
+ terser()
+ ]
+}
+```
+
+By default, this will minify any tagged template literal string whose tag contains "html" or "css" (case insensitive). [Additional options](https://www.npmjs.com/package/minify-html-literals#options) may be specified to control what templates should be minified.
+
+## Options
+
+```ts
+declare const pluginOptions {
+ /**
+ * A picomatch pattern, or array of patterns, which specifies the files in the build the plugin should operate on.
+ */
+ include?: ReadonlyArray<string | RegExp> | string | RegExp | null
+ /**
+ * A picomatch pattern, or array of patterns, which specifies the files in the build the plugin should ignore.
+ */
+ exclude?: typeof pluginOptions.include
+ /**
+ * Minify options, see https://www.npmjs.com/package/minify-html-literals#options.
+ */
+ options?: DefaultOptions
+}
+```

+# @rollup/pluginutils
+
+A set of utility functions commonly used by 🍣 Rollup plugins.
+
+## Requirements
+
+This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
+
+## Install
+
+Using npm:
+
+```console
+npm install @rollup/pluginutils --save-dev
+```
+
+## Usage
+
+```js
+import utils from '@rollup/pluginutils';
+//...
+```
+
+## API
+
+Available utility functions are listed below:
+
+_Note: Parameter names immediately followed by a `?` indicate that the parameter is optional._
+
+### addExtension
+
+Adds an extension to a module ID if one does not exist.
+
+Parameters: `(filename: String, ext?: String)`<br>
+Returns: `String`
+
+```js
+import { addExtension } from '@rollup/pluginutils';
+
+export default function myPlugin(options = {}) {
+ return {
+ resolveId(code, id) {
+ // only adds an extension if there isn't one already
+ id = addExtension(id); // `foo` -> `foo.js`, `foo.js` -> `foo.js`
+ id = addExtension(id, '.myext'); // `foo` -> `foo.myext`, `foo.js` -> `foo.js`
+ }
+ };
+}
+```
+
+### attachScopes
+
+Attaches `Scope` objects to the relevant nodes of an AST. Each `Scope` object has a `scope.contains(name)` method that returns `true` if a given name is defined in the current scope or a parent scope.
+
+Parameters: `(ast: Node, propertyName?: String)`<br>
+Returns: `Object`
+
+See [rollup-plugin-inject](https://github.com/rollup/rollup-plugin-inject) or [rollup-plugin-commonjs](https://github.com/rollup/rollup-plugin-commonjs) for an example of usage.
+
+```js
+import { attachScopes } from '@rollup/pluginutils';
+import { walk } from 'estree-walker';
+
+export default function myPlugin(options = {}) {
+ return {
+ transform(code) {
+ const ast = this.parse(code);
+
+ let scope = attachScopes(ast, 'scope');
+
+ walk(ast, {
+ enter(node) {
+ if (node.scope) scope = node.scope;
+
+ if (!scope.contains('foo')) {
+ // `foo` is not defined, so if we encounter it,
+ // we assume it's a global
+ }
+ },
+ leave(node) {
+ if (node.scope) scope = scope.parent;
+ }
+ });
+ }
+ };
+}
+```
+
+### createFilter
+
+Constructs a filter function which can be used to determine whether or not certain modules should be operated upon.
+
+Parameters: `(include?: <picomatch>, exclude?: <picomatch>, options?: Object)`<br>
+Returns: `String`
+
+#### `include` and `exclude`
+
+Type: `String | RegExp | Array[...String|RegExp]`<br>
+
+A valid [`picomatch`](https://github.com/micromatch/picomatch#globbing-features) pattern, or array of patterns. If `options.include` is omitted or has zero length, filter will return `true` by default. Otherwise, an ID must match one or more of the `picomatch` patterns, and must not match any of the `options.exclude` patterns.
+
+Note that `picomatch` patterns are very similar to [`minimatch`](https://github.com/isaacs/minimatch#readme) patterns, and in most use cases, they are interchangeable. If you have more specific pattern matching needs, you can view [this comparison table](https://github.com/micromatch/picomatch#library-comparisons) to learn more about where the libraries differ.
+
+#### `options`
+
+##### `resolve`
+
+Type: `String | Boolean | null`
+
+Optionally resolves the patterns against a directory other than `process.cwd()`. If a `String` is specified, then the value will be used as the base directory. Relative paths will be resolved against `process.cwd()` first. If `false`, then the patterns will not be resolved against any directory. This can be useful if you want to create a filter for virtual module names.
+
+#### Usage
+
+```js
+import { createFilter } from '@rollup/pluginutils';
+
+export default function myPlugin(options = {}) {
+ // assume that the myPlugin accepts options of `options.include` and `options.exclude`
+ var filter = createFilter(options.include, options.exclude, {
+ resolve: '/my/base/dir'
+ });
+
+ return {
+ transform(code, id) {
+ if (!filter(id)) return;
+
+ // proceed with the transformation...
+ }
+ };
+}
+```
+
+### dataToEsm
+
+Transforms objects into tree-shakable ES Module imports.
+
+Parameters: `(data: Object)`<br>
+Returns: `String`
+
+#### `data`
+
+Type: `Object`
+
+An object to transform into an ES module.
+
+#### Usage
+
+```js
+import { dataToEsm } from '@rollup/pluginutils';
+
+const esModuleSource = dataToEsm(
+ {
+ custom: 'data',
+ to: ['treeshake']
+ },
+ {
+ compact: false,
+ indent: '\t',
+ preferConst: false,
+ objectShorthand: false,
+ namedExports: true
+ }
+);
+/*
+Outputs the string ES module source:
+ export const custom = 'data';
+ export const to = ['treeshake'];
+ export default { custom, to };
+*/
+```
+
+### extractAssignedNames
+
+Extracts the names of all assignment targets based upon specified patterns.
+
+Parameters: `(param: Node)`<br>
+Returns: `Array[...String]`
+
+#### `param`
+
+Type: `Node`
+
+An `acorn` AST Node.
+
+#### Usage
+
+```js
+import { extractAssignedNames } from '@rollup/pluginutils';
+import { walk } from 'estree-walker';
+
+export default function myPlugin(options = {}) {
+ return {
+ transform(code) {
+ const ast = this.parse(code);
+
+ walk(ast, {
+ enter(node) {
+ if (node.type === 'VariableDeclarator') {
+ const declaredNames = extractAssignedNames(node.id);
+ // do something with the declared names
+ // e.g. for `const {x, y: z} = ...` => declaredNames = ['x', 'z']
+ }
+ }
+ });
+ }
+ };
+}
+```
+
+### makeLegalIdentifier
+
+Constructs a bundle-safe identifier from a `String`.
+
+Parameters: `(str: String)`<br>
+Returns: `String`
+
+#### Usage
+
+```js
+import { makeLegalIdentifier } from '@rollup/pluginutils';
+
+makeLegalIdentifier('foo-bar'); // 'foo_bar'
+makeLegalIdentifier('typeof'); // '_typeof'
+```
+
+### normalizePath
+
+Converts path separators to forward slash.
+
+Parameters: `(filename: String)`<br>
+Returns: `String`
+
+#### Usage
+
+```js
+import { normalizePath } from '@rollup/pluginutils';
+
+normalizePath('foo\\bar'); // 'foo/bar'
+normalizePath('foo/bar'); // 'foo/bar'
+```

+UglifyJS 3
+==========
+
+UglifyJS is a JavaScript parser, minifier, compressor and beautifier toolkit.
+
+#### Note:
+- `uglify-js` supports JavaScript and most language features in ECMAScript.
+- For more exotic parts of ECMAScript, process your source file with transpilers
+ like [Babel](https://babeljs.io/) before passing onto `uglify-js`.
+- `uglify-js@3` has a simplified [API](#api-reference) and [CLI](#command-line-usage)
+ that is not backwards compatible with [`uglify-js@2`](https://github.com/mishoo/UglifyJS/tree/v2.x).
+
+Install
+-------
+
+First make sure you have installed the latest version of [node.js](http://nodejs.org/)
+(You may need to restart your computer after this step).
+
+From NPM for use as a command line app:
+
+ npm install uglify-js -g
+
+From NPM for programmatic use:
+
+ npm install uglify-js
+
+# Command line usage
+
+ uglifyjs [input files] [options]
+
+UglifyJS can take multiple input files. It's recommended that you pass the
+input files first, then pass the options. UglifyJS will parse input files
+in sequence and apply any compression options. The files are parsed in the
+same global scope, that is, a reference from a file to some
+variable/function declared in another file will be matched properly.
+
+If no input file is specified, UglifyJS will read from STDIN.
+
+If you wish to pass your options before the input files, separate the two with
+a double dash to prevent input files being used as option arguments:
+
+ uglifyjs --compress --mangle -- input.js
+
+### Command line options
+
+```
+ -h, --help Print usage information.
+ `--help options` for details on available options.
+ -V, --version Print version number.
+ -p, --parse <options> Specify parser options:
+ `acorn` Use Acorn for parsing.
+ `bare_returns` Allow return outside of functions.
+ Useful when minifying CommonJS
+ modules and Userscripts that may
+ be anonymous function wrapped (IIFE)
+ by the .user.js engine `caller`.
+ `expression` Parse a single expression, rather than
+ a program (for parsing JSON).
+ `spidermonkey` Assume input files are SpiderMonkey
+ AST format (as JSON).
+ -c, --compress [options] Enable compressor/specify compressor options:
+ `pure_funcs` List of functions that can be safely
+ removed when their return values are
+ not used.
+ -m, --mangle [options] Mangle names/specify mangler options:
+ `reserved` List of names that should not be mangled.
+ --mangle-props [options] Mangle properties/specify mangler options:
+ `builtins` Mangle property names that overlaps
+ with standard JavaScript globals.
+ `debug` Add debug prefix and suffix.
+ `domprops` Mangle property names that overlaps
+ with DOM properties.
+ `keep_quoted` Only mangle unquoted properties.
+ `regex` Only mangle matched property names.
+ `reserved` List of names that should not be mangled.
+ -b, --beautify [options] Beautify output/specify output options:
+ `beautify` Enabled with `--beautify` by default.
+ `preamble` Preamble to prepend to the output. You
+ can use this to insert a comment, for
+ example for licensing information.
+ This will not be parsed, but the source
+ map will adjust for its presence.
+ `quote_style` Quote style:
+ 0 - auto
+ 1 - single
+ 2 - double
+ 3 - original
+ `wrap_iife` Wrap IIFEs in parentheses. Note: you may
+ want to disable `negate_iife` under
+ compressor options.
+ -O, --output-opts [options] Specify output options (`beautify` disabled by default).
+ -o, --output <file> Output file path (default STDOUT). Specify `ast` or
+ `spidermonkey` to write UglifyJS or SpiderMonkey AST
+ as JSON to STDOUT respectively.
+ --annotations Process and preserve comment annotations.
+ (`/*@__PURE__*/` or `/*#__PURE__*/`)
+ --no-annotations Ignore and discard comment annotations.
+ --comments [filter] Preserve copyright comments in the output. By
+ default this works like Google Closure, keeping
+ JSDoc-style comments that contain "@license" or
+ "@preserve". You can optionally pass one of the
+ following arguments to this flag:
+ - "all" to keep all comments
+ - a valid JS RegExp like `/foo/` or `/^!/` to
+ keep only matching comments.
+ Note that currently not *all* comments can be
+ kept when compression is on, because of dead
+ code removal or cascading statements into
+ sequences.
+ --config-file <file> Read `minify()` options from JSON file.
+ -d, --define <expr>[=value] Global definitions.
+ -e, --enclose [arg[:value]] Embed everything in a big function, with configurable
+ argument(s) & value(s).
+ --ie8 Support non-standard Internet Explorer 8.
+ Equivalent to setting `ie8: true` in `minify()`
+ for `compress`, `mangle` and `output` options.
+ By default UglifyJS will not try to be IE-proof.
+ --keep-fnames Do not mangle/drop function names. Useful for
+ code relying on Function.prototype.name.
+ --name-cache <file> File to hold mangled name mappings.
+ --self Build UglifyJS as a library (implies --wrap UglifyJS)
+ --source-map [options] Enable source map/specify source map options:
+ `base` Path to compute relative paths from input files.
+ `content` Input source map, useful if you're compressing
+ JS that was generated from some other original
+ code. Specify "inline" if the source map is
+ included within the sources.
+ `filename` Filename and/or location of the output source
+ (sets `file` attribute in source map).
+ `includeSources` Pass this flag if you want to include
+ the content of source files in the
+ source map as sourcesContent property.
+ `names` Include symbol names in the source map.
+ `root` Path to the original source to be included in
+ the source map.
+ `url` If specified, path to the source map to append in
+ `//# sourceMappingURL`.
+ --timings Display operations run time on STDERR.
+ --toplevel Compress and/or mangle variables in top level scope.
+ --v8 Support non-standard Chrome & Node.js
+ Equivalent to setting `v8: true` in `minify()`
+ for `mangle` and `output` options.
+ By default UglifyJS will not try to be v8-proof.
+ --verbose Print diagnostic messages.
+ --warn Print warning messages.
+ --webkit Support non-standard Safari/Webkit.
+ Equivalent to setting `webkit: true` in `minify()`
+ for `mangle` and `output` options.
+ By default UglifyJS will not try to be Safari-proof.
+ --wrap <name> Embed everything in a big function, making the
+ “exports” and “global” variables available. You
+ need to pass an argument to this option to
+ specify the name that your module will take
+ when included in, say, a browser.
+```
+
+Specify `--output` (`-o`) to declare the output file. Otherwise the output
+goes to STDOUT.
+
+## CLI source map options
+
+UglifyJS can generate a source map file, which is highly useful for
+debugging your compressed JavaScript. To get a source map, pass
+`--source-map --output output.js` (source map will be written out to
+`output.js.map`).
+
+Additional options:
+
+- `--source-map "filename='<NAME>'"` to specify the name of the source map. The value of
+ `filename` is only used to set `file` attribute (see [the spec][sm-spec])
+ in source map file.
+
+- `--source-map "root='<URL>'"` to pass the URL where the original files can be found.
+
+- `--source-map "names=false"` to omit symbol names if you want to reduce size
+ of the source map file.
+
+- `--source-map "url='<URL>'"` to specify the URL where the source map can be found.
+ Otherwise UglifyJS assumes HTTP `X-SourceMap` is being used and will omit the
+ `//# sourceMappingURL=` directive.
+
+For example:
+
+ uglifyjs js/file1.js js/file2.js \
+ -o foo.min.js -c -m \
+ --source-map "root='http://foo.com/src',url='foo.min.js.map'"
+
+The above will compress and mangle `file1.js` and `file2.js`, will drop the
+output in `foo.min.js` and the source map in `foo.min.js.map`. The source
+mapping will refer to `http://foo.com/src/js/file1.js` and
+`http://foo.com/src/js/file2.js` (in fact it will list `http://foo.com/src`
+as the source map root, and the original files as `js/file1.js` and
+`js/file2.js`).
+
+### Composed source map
+
+When you're compressing JS code that was output by a compiler such as
+CoffeeScript, mapping to the JS code won't be too helpful. Instead, you'd
+like to map back to the original code (i.e. CoffeeScript). UglifyJS has an
+option to take an input source map. Assuming you have a mapping from
+CoffeeScript → compiled JS, UglifyJS can generate a map from CoffeeScript →
+compressed JS by mapping every token in the compiled JS to its original
+location.
+
+To use this feature pass `--source-map "content='/path/to/input/source.map'"`
+or `--source-map "content=inline"` if the source map is included inline with
+the sources.
+
+## CLI compress options
+
+You need to pass `--compress` (`-c`) to enable the compressor. Optionally
+you can pass a comma-separated list of [compress options](#compress-options).
+
+Options are in the form `foo=bar`, or just `foo` (the latter implies
+a boolean option that you want to set `true`; it's effectively a
+shortcut for `foo=true`).
+
+Example:
+
+ uglifyjs file.js -c toplevel,sequences=false
+
+## CLI mangle options
+
+To enable the mangler you need to pass `--mangle` (`-m`). The following
+(comma-separated) options are supported:
+
+- `eval` (default: `false`) — mangle names visible in scopes where `eval` or
+ `with` are used.
+
+- `reserved` (default: `[]`) — when mangling is enabled but you want to
+ prevent certain names from being mangled, you can declare those names with
+ `--mangle reserved` — pass a comma-separated list of names. For example:
+
+ uglifyjs ... -m reserved=['$','require','exports']
+
+ to prevent the `require`, `exports` and `$` names from being changed.
+
+### CLI mangling property names (`--mangle-props`)
+
+**Note:** THIS WILL PROBABLY BREAK YOUR CODE. Mangling property names
+is a separate step, different from variable name mangling. Pass
+`--mangle-props` to enable it. It will mangle all properties in the
+input code with the exception of built in DOM properties and properties
+in core JavaScript classes. For example:
+
+```javascript
+// example.js
+var x = {
+ baz_: 0,
+ foo_: 1,
+ calc: function() {
+ return this.foo_ + this.baz_;
+ }
+};
+x.bar_ = 2;
+x["baz_"] = 3;
+console.log(x.calc());
+```
+Mangle all properties (except for JavaScript `builtins`):
+```bash
+$ uglifyjs example.js -c -m --mangle-props
+```
+```javascript
+var x={o:0,_:1,l:function(){return this._+this.o}};x.t=2,x.o=3,console.log(x.l());
+```
+Mangle all properties except for `reserved` properties:
+```bash
+$ uglifyjs example.js -c -m --mangle-props reserved=[foo_,bar_]
+```
+```javascript
+var x={o:0,foo_:1,_:function(){return this.foo_+this.o}};x.bar_=2,x.o=3,console.log(x._());
+```
+Mangle all properties matching a `regex`:
+```bash
+$ uglifyjs example.js -c -m --mangle-props regex=/_$/
+```
+```javascript
+var x={o:0,_:1,calc:function(){return this._+this.o}};x.l=2,x.o=3,console.log(x.calc());
+```
+
+Combining mangle properties options:
+```bash
+$ uglifyjs example.js -c -m --mangle-props regex=/_$/,reserved=[bar_]
+```
+```javascript
+var x={o:0,_:1,calc:function(){return this._+this.o}};x.bar_=2,x.o=3,console.log(x.calc());
+```
+
+In order for this to be of any use, we avoid mangling standard JS names by
+default (`--mangle-props builtins` to override).
+
+A default exclusion file is provided in `tools/domprops.json` which should
+cover most standard JS and DOM properties defined in various browsers. Pass
+`--mangle-props domprops` to disable this feature.
+
+A regular expression can be used to define which property names should be
+mangled. For example, `--mangle-props regex=/^_/` will only mangle property
+names that start with an underscore.
+
+When you compress multiple files using this option, in order for them to
+work together in the end we need to ensure somehow that one property gets
+mangled to the same name in all of them. For this, pass `--name-cache filename.json`
+and UglifyJS will maintain these mappings in a file which can then be reused.
+It should be initially empty. Example:
+
+```bash
+$ rm -f /tmp/cache.json # start fresh
+$ uglifyjs file1.js file2.js --mangle-props --name-cache /tmp/cache.json -o part1.js
+$ uglifyjs file3.js file4.js --mangle-props --name-cache /tmp/cache.json -o part2.js
+```
+
+Now, `part1.js` and `part2.js` will be consistent with each other in terms
+of mangled property names.
+
+Using the name cache is not necessary if you compress all your files in a
+single call to UglifyJS.
+
+### Mangling unquoted names (`--mangle-props keep_quoted`)
+
+Using quoted property name (`o["foo"]`) reserves the property name (`foo`)
+so that it is not mangled throughout the entire script even when used in an
+unquoted style (`o.foo`). Example:
+
+```javascript
+// stuff.js
+var o = {
+ "foo": 1,
+ bar: 3
+};
+o.foo += o.bar;
+console.log(o.foo);
+```
+```bash
+$ uglifyjs stuff.js --mangle-props keep_quoted -c -m
+```
+```javascript
+var o={foo:1,o:3};o.foo+=o.o,console.log(o.foo);
+```
+
+### Debugging property name mangling
+
+You can also pass `--mangle-props debug` in order to mangle property names
+without completely obscuring them. For example the property `o.foo`
+would mangle to `o._$foo$_` with this option. This allows property mangling
+of a large codebase while still being able to debug the code and identify
+where mangling is breaking things.
+
+```bash
+$ uglifyjs stuff.js --mangle-props debug -c -m
+```
+```javascript
+var o={_$foo$_:1,_$bar$_:3};o._$foo$_+=o._$bar$_,console.log(o._$foo$_);
+```
+
+You can also pass a custom suffix using `--mangle-props debug=XYZ`. This would then
+mangle `o.foo` to `o._$foo$XYZ_`. You can change this each time you compile a
+script to identify how a property got mangled. One technique is to pass a
+random number on every compile to simulate mangling changing with different
+inputs (e.g. as you update the input script with new properties), and to help
+identify mistakes like writing mangled keys to storage.
+
+
+# API Reference
+
+Assuming installation via NPM, you can load UglifyJS in your application
+like this:
+```javascript
+var UglifyJS = require("uglify-js");
+```
+
+There is a single high level function, **`minify(code, options)`**,
+which will perform all minification [phases](#minify-options) in a configurable
+manner. By default `minify()` will enable the options [`compress`](#compress-options)
+and [`mangle`](#mangle-options). Example:
+```javascript
+var code = "function add(first, second) { return first + second; }";
+var result = UglifyJS.minify(code);
+console.log(result.error); // runtime error, or `undefined` if no error
+console.log(result.code); // minified output: function add(n,d){return n+d}
+```
+
+You can `minify` more than one JavaScript file at a time by using an object
+for the first argument where the keys are file names and the values are source
+code:
+```javascript
+var code = {
+ "file1.js": "function add(first, second) { return first + second; }",
+ "file2.js": "console.log(add(1 + 2, 3 + 4));"
+};
+var result = UglifyJS.minify(code);
+console.log(result.code);
+// function add(d,n){return d+n}console.log(add(3,7));
+```
+
+The `toplevel` option:
+```javascript
+var code = {
+ "file1.js": "function add(first, second) { return first + second; }",
+ "file2.js": "console.log(add(1 + 2, 3 + 4));"
+};
+var options = { toplevel: true };
+var result = UglifyJS.minify(code, options);
+console.log(result.code);
+// console.log(3+7);
+```
+
+The `nameCache` option:
+```javascript
+var options = {
+ mangle: {
+ toplevel: true,
+ },
+ nameCache: {}
+};
+var result1 = UglifyJS.minify({
+ "file1.js": "function add(first, second) { return first + second; }"
+}, options);
+var result2 = UglifyJS.minify({
+ "file2.js": "console.log(add(1 + 2, 3 + 4));"
+}, options);
+console.log(result1.code);
+// function n(n,r){return n+r}
+console.log(result2.code);
+// console.log(n(3,7));
+```
+
+You may persist the name cache to the file system in the following way:
+```javascript
+var cacheFileName = "/tmp/cache.json";
+var options = {
+ mangle: {
+ properties: true,
+ },
+ nameCache: JSON.parse(fs.readFileSync(cacheFileName, "utf8"))
+};
+fs.writeFileSync("part1.js", UglifyJS.minify({
+ "file1.js": fs.readFileSync("file1.js", "utf8"),
+ "file2.js": fs.readFileSync("file2.js", "utf8")
+}, options).code, "utf8");
+fs.writeFileSync("part2.js", UglifyJS.minify({
+ "file3.js": fs.readFileSync("file3.js", "utf8"),
+ "file4.js": fs.readFileSync("file4.js", "utf8")
+}, options).code, "utf8");
+fs.writeFileSync(cacheFileName, JSON.stringify(options.nameCache), "utf8");
+```
+
+An example of a combination of `minify()` options:
+```javascript
+var code = {
+ "file1.js": "function add(first, second) { return first + second; }",
+ "file2.js": "console.log(add(1 + 2, 3 + 4));"
+};
+var options = {
+ toplevel: true,
+ compress: {
+ global_defs: {
+ "@console.log": "alert"
+ },
+ passes: 2
+ },
+ output: {
+ beautify: false,
+ preamble: "/* uglified */"
+ }
+};
+var result = UglifyJS.minify(code, options);
+console.log(result.code);
+// /* uglified */
+// alert(10);"
+```
+
+To produce warnings:
+```javascript
+var code = "function f(){ var u; return 2 + 3; }";
+var options = { warnings: true };
+var result = UglifyJS.minify(code, options);
+console.log(result.error); // runtime error, `undefined` in this case
+console.log(result.warnings); // [ 'Dropping unused variable u [0:1,18]' ]
+console.log(result.code); // function f(){return 5}
+```
+
+An error example:
+```javascript
+var result = UglifyJS.minify({"foo.js" : "if (0) else console.log(1);"});
+console.log(JSON.stringify(result.error));
+// {"message":"Unexpected token: keyword (else)","filename":"foo.js","line":1,"col":7,"pos":7}
+```
+Note: unlike `uglify-js@2.x`, the `3.x` API does not throw errors. To
+achieve a similar effect one could do the following:
+```javascript
+var result = UglifyJS.minify(code, options);
+if (result.error) throw result.error;
+```
+
+## Minify options
+
+- `annotations` — pass `false` to ignore all comment annotations and elide them
+ from output. Useful when, for instance, external tools incorrectly applied
+ `/*@__PURE__*/` or `/*#__PURE__*/`. Pass `true` to both compress and retain
+ comment annotations in output to allow for further processing downstream.
+
+- `compress` (default: `{}`) — pass `false` to skip compressing entirely.
+ Pass an object to specify custom [compress options](#compress-options).
+
+- `ie8` (default: `false`) — set to `true` to support IE8.
+
+- `keep_fnames` (default: `false`) — pass `true` to prevent discarding or mangling
+ of function names. Useful for code relying on `Function.prototype.name`.
+
+- `mangle` (default: `true`) — pass `false` to skip mangling names, or pass
+ an object to specify [mangle options](#mangle-options) (see below).
+
+ - `mangle.properties` (default: `false`) — a subcategory of the mangle option.
+ Pass an object to specify custom [mangle property options](#mangle-properties-options).
+
+- `nameCache` (default: `null`) — pass an empty object `{}` or a previously
+ used `nameCache` object if you wish to cache mangled variable and
+ property names across multiple invocations of `minify()`. Note: this is
+ a read/write property. `minify()` will read the name cache state of this
+ object and update it during minification so that it may be
+ reused or externally persisted by the user.
+
+- `output` (default: `null`) — pass an object if you wish to specify
+ additional [output options](#output-options). The defaults are optimized
+ for best compression.
+
+- `parse` (default: `{}`) — pass an object if you wish to specify some
+ additional [parse options](#parse-options).
+
+- `sourceMap` (default: `false`) — pass an object if you wish to specify
+ [source map options](#source-map-options).
+
+- `toplevel` (default: `false`) — set to `true` if you wish to enable top level
+ variable and function name mangling and to drop unused variables and functions.
+
+- `v8` (default: `false`) — enable workarounds for Chrome & Node.js bugs.
+
+- `warnings` (default: `false`) — pass `true` to return compressor warnings
+ in `result.warnings`. Use the value `"verbose"` for more detailed warnings.
+
+- `webkit` (default: `false`) — enable workarounds for Safari/WebKit bugs.
+ PhantomJS users should set this option to `true`.
+
+## Minify options structure
+
+```javascript
+{
+ parse: {
+ // parse options
+ },
+ compress: {
+ // compress options
+ },
+ mangle: {
+ // mangle options
+
+ properties: {
+ // mangle property options
+ }
+ },
+ output: {
+ // output options
+ },
+ sourceMap: {
+ // source map options
+ },
+ nameCache: null, // or specify a name cache object
+ toplevel: false,
+ ie8: false,
+ warnings: false,
+}
+```
+
+### Source map options
+
+To generate a source map:
+```javascript
+var result = UglifyJS.minify({"file1.js": "var a = function() {};"}, {
+ sourceMap: {
+ filename: "out.js",
+ url: "out.js.map"
+ }
+});
+console.log(result.code); // minified output
+console.log(result.map); // source map
+```
+
+Note that the source map is not saved in a file, it's just returned in
+`result.map`. The value passed for `sourceMap.url` is only used to set
+`//# sourceMappingURL=out.js.map` in `result.code`. The value of
+`filename` is only used to set `file` attribute (see [the spec][sm-spec])
+in source map file.
+
+You can set option `sourceMap.url` to be `"inline"` and source map will
+be appended to code.
+
+You can also specify sourceRoot property to be included in source map:
+```javascript
+var result = UglifyJS.minify({"file1.js": "var a = function() {};"}, {
+ sourceMap: {
+ root: "http://example.com/src",
+ url: "out.js.map"
+ }
+});
+```
+
+If you're compressing compiled JavaScript and have a source map for it, you
+can use `sourceMap.content`:
+```javascript
+var result = UglifyJS.minify({"compiled.js": "compiled code"}, {
+ sourceMap: {
+ content: "content from compiled.js.map",
+ url: "minified.js.map"
+ }
+});
+// same as before, it returns `code` and `map`
+```
+
+If you're using the `X-SourceMap` header instead, you can just omit `sourceMap.url`.
+
+If you wish to reduce file size of the source map, set option `sourceMap.names`
+to be `false` and all symbol names will be omitted.
+
+## Parse options
+
+- `bare_returns` (default: `false`) — support top level `return` statements
+
+- `html5_comments` (default: `true`)
+
+- `shebang` (default: `true`) — support `#!command` as the first line
+
+## Compress options
+
+- `annotations` (default: `true`) — Pass `false` to disable potentially dropping
+ functions marked as "pure". A function call is marked as "pure" if a comment
+ annotation `/*@__PURE__*/` or `/*#__PURE__*/` immediately precedes the call. For
+ example: `/*@__PURE__*/foo();`
+
+- `arguments` (default: `true`) — replace `arguments[index]` with function
+ parameter name whenever possible.
+
+- `arrows` (default: `true`) — apply optimizations to arrow functions
+
+- `assignments` (default: `true`) — apply optimizations to assignment expressions
+
+- `awaits` (default: `true`) — apply optimizations to `await` expressions
+
+- `booleans` (default: `true`) — various optimizations for boolean context,
+ for example `!!a ? b : c → a ? b : c`
+
+- `collapse_vars` (default: `true`) — Collapse single-use non-constant variables,
+ side effects permitting.
+
+- `comparisons` (default: `true`) — apply certain optimizations to binary nodes,
+ e.g. `!(a <= b) → a > b`, attempts to negate binary nodes, e.g.
+ `a = !b && !c && !d && !e → a=!(b||c||d||e)` etc.
+
+- `conditionals` (default: `true`) — apply optimizations for `if`-s and conditional
+ expressions
+
+- `dead_code` (default: `true`) — remove unreachable code
+
+- `default_values` (default: `true`) — drop overshadowed default values
+
+- `directives` (default: `true`) — remove redundant or non-standard directives
+
+- `drop_console` (default: `false`) — Pass `true` to discard calls to
+ `console.*` functions. If you wish to drop a specific function call
+ such as `console.info` and/or retain side effects from function arguments
+ after dropping the function call then use `pure_funcs` instead.
+
+- `drop_debugger` (default: `true`) — remove `debugger;` statements
+
+- `evaluate` (default: `true`) — Evaluate expression for shorter constant
+ representation. Pass `"eager"` to always replace function calls whenever
+ possible, or a positive integer to specify an upper bound for each individual
+ evaluation in number of characters.
+
+- `expression` (default: `false`) — Pass `true` to preserve completion values
+ from terminal statements without `return`, e.g. in bookmarklets.
+
+- `functions` (default: `true`) — convert declarations from `var` to `function`
+ whenever possible.
+
+- `global_defs` (default: `{}`) — see [conditional compilation](#conditional-compilation)
+
+- `hoist_exports` (default: `true`) — hoist `export` statements to facilitate
+ various `compress` and `mangle` optimizations.
+
+- `hoist_funs` (default: `false`) — hoist function declarations
+
+- `hoist_props` (default: `true`) — hoist properties from constant object and
+ array literals into regular variables subject to a set of constraints. For example:
+ `var o={p:1, q:2}; f(o.p, o.q);` is converted to `f(1, 2);`. Note: `hoist_props`
+ works best with `toplevel` and `mangle` enabled, alongside with `compress` option
+ `passes` set to `2` or higher.
+
+- `hoist_vars` (default: `false`) — hoist `var` declarations (this is `false`
+ by default because it seems to increase the size of the output in general)
+
+- `if_return` (default: `true`) — optimizations for if/return and if/continue
+
+- `imports` (default: `true`) — drop unreferenced import symbols when used with `unused`
+
+- `inline` (default: `true`) — inline calls to function with simple/`return` statement:
+ - `false` — same as `0`
+ - `0` — disabled inlining
+ - `1` — inline simple functions
+ - `2` — inline functions with arguments
+ - `3` — inline functions with arguments and variables
+ - `true` — same as `3`
+
+- `join_vars` (default: `true`) — join consecutive `var` statements
+
+- `keep_fargs` (default: `false`) — discard unused function arguments except
+ when unsafe to do so, e.g. code which relies on `Function.prototype.length`.
+ Pass `true` to always retain function arguments.
+
+- `keep_infinity` (default: `false`) — Pass `true` to prevent `Infinity` from
+ being compressed into `1/0`, which may cause performance issues on Chrome.
+
+- `loops` (default: `true`) — optimizations for `do`, `while` and `for` loops
+ when we can statically determine the condition.
+
+- `merge_vars` (default: `true`) — combine and reuse variables.
+
+- `negate_iife` (default: `true`) — negate "Immediately-Called Function Expressions"
+ where the return value is discarded, to avoid the parens that the
+ code generator would insert.
+
+- `objects` (default: `true`) — compact duplicate keys in object literals.
+
+- `passes` (default: `1`) — The maximum number of times to run compress.
+ In some cases more than one pass leads to further compressed code. Keep in
+ mind more passes will take more time.
+
+- `properties` (default: `true`) — rewrite property access using the dot notation, for
+ example `foo["bar"] → foo.bar`
+
+- `pure_funcs` (default: `null`) — You can pass an array of names and
+ UglifyJS will assume that those functions do not produce side
+ effects. DANGER: will not check if the name is redefined in scope.
+ An example case here, for instance `var q = Math.floor(a/b)`. If
+ variable `q` is not used elsewhere, UglifyJS will drop it, but will
+ still keep the `Math.floor(a/b)`, not knowing what it does. You can
+ pass `pure_funcs: [ 'Math.floor' ]` to let it know that this
+ function won't produce any side effect, in which case the whole
+ statement would get discarded. The current implementation adds some
+ overhead (compression will be slower). Make sure symbols under `pure_funcs`
+ are also under `mangle.reserved` to avoid mangling.
+
+- `pure_getters` (default: `"strict"`) — If you pass `true` for
+ this, UglifyJS will assume that object property access
+ (e.g. `foo.bar` or `foo["bar"]`) doesn't have any side effects.
+ Specify `"strict"` to treat `foo.bar` as side-effect-free only when
+ `foo` is certain to not throw, i.e. not `null` or `undefined`.
+
+- `reduce_funcs` (default: `true`) — Allows single-use functions to be
+ inlined as function expressions when permissible allowing further
+ optimization. Enabled by default. Option depends on `reduce_vars`
+ being enabled. Some code runs faster in the Chrome V8 engine if this
+ option is disabled. Does not negatively impact other major browsers.
+
+- `reduce_vars` (default: `true`) — Improve optimization on variables assigned with and
+ used as constant values.
+
+- `rests` (default: `true`) — apply optimizations to rest parameters
+
+- `sequences` (default: `true`) — join consecutive simple statements using the
+ comma operator. May be set to a positive integer to specify the maximum number
+ of consecutive comma sequences that will be generated. If this option is set to
+ `true` then the default `sequences` limit is `200`. Set option to `false` or `0`
+ to disable. The smallest `sequences` length is `2`. A `sequences` value of `1`
+ is grandfathered to be equivalent to `true` and as such means `200`. On rare
+ occasions the default sequences limit leads to very slow compress times in which
+ case a value of `20` or less is recommended.
+
+- `side_effects` (default: `true`) — drop extraneous code which does not affect
+ outcome of runtime execution.
+
+- `spreads` (default: `true`) — flatten spread expressions.
+
+- `strings` (default: `true`) — compact string concatenations.
+
+- `switches` (default: `true`) — de-duplicate and remove unreachable `switch` branches
+
+- `templates` (default: `true`) — compact template literals by embedding expressions
+ and/or converting to string literals, e.g. `` `foo ${42}` → "foo 42"``
+
+- `top_retain` (default: `null`) — prevent specific toplevel functions and
+ variables from `unused` removal (can be array, comma-separated, RegExp or
+ function. Implies `toplevel`)
+
+- `toplevel` (default: `false`) — drop unreferenced functions (`"funcs"`) and/or
+ variables (`"vars"`) in the top level scope (`false` by default, `true` to drop
+ both unreferenced functions and variables)
+
+- `typeofs` (default: `true`) — Transforms `typeof foo == "undefined"` into
+ `foo === void 0`. Note: recommend to set this value to `false` for IE10 and
+ earlier versions due to known issues.
+
+- `unsafe` (default: `false`) — apply "unsafe" transformations (discussion below)
+
+- `unsafe_comps` (default: `false`) — compress expressions like `a <= b` assuming
+ none of the operands can be (coerced to) `NaN`.
+
+- `unsafe_Function` (default: `false`) — compress and mangle `Function(args, code)`
+ when both `args` and `code` are string literals.
+
+- `unsafe_math` (default: `false`) — optimize numerical expressions like
+ `2 * x * 3` into `6 * x`, which may give imprecise floating point results.
+
+- `unsafe_proto` (default: `false`) — optimize expressions like
+ `Array.prototype.slice.call(a)` into `[].slice.call(a)`
+
+- `unsafe_regexp` (default: `false`) — enable substitutions of variables with
+ `RegExp` values the same way as if they are constants.
+
+- `unsafe_undefined` (default: `false`) — substitute `void 0` if there is a
+ variable named `undefined` in scope (variable name will be mangled, typically
+ reduced to a single character)
+
+- `unused` (default: `true`) — drop unreferenced functions and variables (simple
+ direct variable assignments do not count as references unless set to `"keep_assign"`)
+
+- `varify` (default: `true`) — convert block-scoped declaractions into `var`
+ whenever safe to do so
+
+- `yields` (default: `true`) — apply optimizations to `yield` expressions
+
+## Mangle options
+
+- `eval` (default: `false`) — Pass `true` to mangle names visible in scopes
+ where `eval` or `with` are used.
+
+- `reserved` (default: `[]`) — Pass an array of identifiers that should be
+ excluded from mangling. Example: `["foo", "bar"]`.
+
+- `toplevel` (default: `false`) — Pass `true` to mangle names declared in the
+ top level scope.
+
+Examples:
+
+```javascript
+// test.js
+var globalVar;
+function funcName(firstLongName, anotherLongName) {
+ var myVariable = firstLongName + anotherLongName;
+}
+```
+```javascript
+var code = fs.readFileSync("test.js", "utf8");
+
+UglifyJS.minify(code).code;
+// 'function funcName(a,n){}var globalVar;'
+
+UglifyJS.minify(code, { mangle: { reserved: ['firstLongName'] } }).code;
+// 'function funcName(firstLongName,a){}var globalVar;'
+
+UglifyJS.minify(code, { mangle: { toplevel: true } }).code;
+// 'function n(n,a){}var a;'
+```
+
+### Mangle properties options
+
+- `builtins` (default: `false`) — Use `true` to allow the mangling of builtin
+ DOM properties. Not recommended to override this setting.
+
+- `debug` (default: `false`) — Mangle names with the original name still present.
+ Pass an empty string `""` to enable, or a non-empty string to set the debug suffix.
+
+- `keep_quoted` (default: `false`) — Only mangle unquoted property names.
+
+- `regex` (default: `null`) — Pass a RegExp literal to only mangle property
+ names matching the regular expression.
+
+- `reserved` (default: `[]`) — Do not mangle property names listed in the
+ `reserved` array.
+
+## Output options
+
+The code generator tries to output shortest code possible by default. In
+case you want beautified output, pass `--beautify` (`-b`). Optionally you
+can pass additional arguments that control the code output:
+
+- `annotations` (default: `false`) — pass `true` to retain comment annotations
+ `/*@__PURE__*/` or `/*#__PURE__*/`, otherwise they will be discarded even if
+ `comments` is set.
+
+- `ascii_only` (default: `false`) — escape Unicode characters in strings and
+ regexps (affects directives with non-ascii characters becoming invalid)
+
+- `beautify` (default: `true`) — whether to actually beautify the output.
+ Passing `-b` will set this to true, but you might need to pass `-b` even
+ when you want to generate minified code, in order to specify additional
+ arguments, so you can use `-b beautify=false` to override it.
+
+- `braces` (default: `false`) — always insert braces in `if`, `for`,
+ `do`, `while` or `with` statements, even if their body is a single
+ statement.
+
+- `comments` (default: `false`) — pass `true` or `"all"` to preserve all
+ comments, `"some"` to preserve multi-line comments that contain `@cc_on`,
+ `@license`, or `@preserve` (case-insensitive), a regular expression string
+ (e.g. `/^!/`), or a function which returns `boolean`, e.g.
+ ```javascript
+ function(node, comment) {
+ return comment.value.indexOf("@type " + node.TYPE) >= 0;
+ }
+ ```
+
+- `galio` (default: `false`) — enable workarounds for ANT Galio bugs
+
+- `indent_level` (default: `4`)
+
+- `indent_start` (default: `0`) — prefix all lines by that many spaces
+
+- `inline_script` (default: `true`) — escape HTML comments and the slash in
+ occurrences of `</script>` in strings
+
+- `keep_quoted_props` (default: `false`) — when turned on, prevents stripping
+ quotes from property names in object literals.
+
+- `max_line_len` (default: `false`) — maximum line length (for uglified code)
+
+- `preamble` (default: `null`) — when passed it must be a string and
+ it will be prepended to the output literally. The source map will
+ adjust for this text. Can be used to insert a comment containing
+ licensing information, for example.
+
+- `preserve_line` (default: `false`) — pass `true` to retain line numbering on
+ a best effort basis.
+
+- `quote_keys` (default: `false`) — pass `true` to quote all keys in literal
+ objects
+
+- `quote_style` (default: `0`) — preferred quote style for strings (affects
+ quoted property names and directives as well):
+ - `0` — prefers double quotes, switches to single quotes when there are
+ more double quotes in the string itself. `0` is best for gzip size.
+ - `1` — always use single quotes
+ - `2` — always use double quotes
+ - `3` — always use the original quotes
+
+- `semicolons` (default: `true`) — separate statements with semicolons. If
+ you pass `false` then whenever possible we will use a newline instead of a
+ semicolon, leading to more readable output of uglified code (size before
+ gzip could be smaller; size after gzip insignificantly larger).
+
+- `shebang` (default: `true`) — preserve shebang `#!` in preamble (bash scripts)
+
+- `width` (default: `80`) — only takes effect when beautification is on, this
+ specifies an (orientative) line width that the beautifier will try to
+ obey. It refers to the width of the line text (excluding indentation).
+ It doesn't work very well currently, but it does make the code generated
+ by UglifyJS more readable.
+
+- `wrap_iife` (default: `false`) — pass `true` to wrap immediately invoked
+ function expressions. See
+ [#640](https://github.com/mishoo/UglifyJS/issues/640) for more details.
+
+# Miscellaneous
+
+### Keeping copyright notices or other comments
+
+You can pass `--comments` to retain certain comments in the output. By
+default it will keep JSDoc-style comments that contain "@preserve",
+"@license" or "@cc_on" (conditional compilation for IE). You can pass
+`--comments all` to keep all the comments, or a valid JavaScript regexp to
+keep only comments that match this regexp. For example `--comments /^!/`
+will keep comments like `/*! Copyright Notice */`.
+
+Note, however, that there might be situations where comments are lost. For
+example:
+```javascript
+function f() {
+ /** @preserve Foo Bar */
+ function g() {
+ // this function is never called
+ }
+ return something();
+}
+```
+
+Even though it has "@preserve", the comment will be lost because the inner
+function `g` (which is the AST node to which the comment is attached to) is
+discarded by the compressor as not referenced.
+
+The safest comments where to place copyright information (or other info that
+needs to be kept in the output) are comments attached to toplevel nodes.
+
+### The `unsafe` `compress` option
+
+It enables some transformations that *might* break code logic in certain
+contrived cases, but should be fine for most code. You might want to try it
+on your own code, it should reduce the minified size. Here's what happens
+when this flag is on:
+
+- `new Array(1, 2, 3)` or `Array(1, 2, 3)` → `[ 1, 2, 3 ]`
+- `new Object()` → `{}`
+- `String(exp)` or `exp.toString()` → `"" + exp`
+- `new Object/RegExp/Function/Error/Array (...)` → we discard the `new`
+
+### Conditional compilation
+
+You can use the `--define` (`-d`) switch in order to declare global
+variables that UglifyJS will assume to be constants (unless defined in
+scope). For example if you pass `--define DEBUG=false` then, coupled with
+dead code removal UglifyJS will discard the following from the output:
+```javascript
+if (DEBUG) {
+ console.log("debug stuff");
+}
+```
+
+You can specify nested constants in the form of `--define env.DEBUG=false`.
+
+UglifyJS will warn about the condition being always false and about dropping
+unreachable code; for now there is no option to turn off only this specific
+warning, you can pass `warnings=false` to turn off *all* warnings.
+
+Another way of doing that is to declare your globals as constants in a
+separate file and include it into the build. For example you can have a
+`build/defines.js` file with the following:
+```javascript
+var DEBUG = false;
+var PRODUCTION = true;
+// etc.
+```
+
+and build your code like this:
+
+ uglifyjs build/defines.js js/foo.js js/bar.js... -c
+
+UglifyJS will notice the constants and, since they cannot be altered, it
+will evaluate references to them to the value itself and drop unreachable
+code as usual. The build will contain the `const` declarations if you use
+them. If you are targeting < ES6 environments which does not support `const`,
+using `var` with `reduce_vars` (enabled by default) should suffice.
+
+### Conditional compilation API
+
+You can also use conditional compilation via the programmatic API. With the difference that the
+property name is `global_defs` and is a compressor property:
+
+```javascript
+var result = UglifyJS.minify(fs.readFileSync("input.js", "utf8"), {
+ compress: {
+ dead_code: true,
+ global_defs: {
+ DEBUG: false
+ }
+ }
+});
+```
+
+To replace an identifier with an arbitrary non-constant expression it is
+necessary to prefix the `global_defs` key with `"@"` to instruct UglifyJS
+to parse the value as an expression:
+```javascript
+UglifyJS.minify("alert('hello');", {
+ compress: {
+ global_defs: {
+ "@alert": "console.log"
+ }
+ }
+}).code;
+// returns: 'console.log("hello");'
+```
+
+Otherwise it would be replaced as string literal:
+```javascript
+UglifyJS.minify("alert('hello');", {
+ compress: {
+ global_defs: {
+ "alert": "console.log"
+ }
+ }
+}).code;
+// returns: '"console.log"("hello");'
+```
+
+### Using native Uglify AST with `minify()`
+```javascript
+// example: parse only, produce native Uglify AST
+
+var result = UglifyJS.minify(code, {
+ parse: {},
+ compress: false,
+ mangle: false,
+ output: {
+ ast: true,
+ code: false // optional - faster if false
+ }
+});
+
+// result.ast contains native Uglify AST
+```
+```javascript
+// example: accept native Uglify AST input and then compress and mangle
+// to produce both code and native AST.
+
+var result = UglifyJS.minify(ast, {
+ compress: {},
+ mangle: {},
+ output: {
+ ast: true,
+ code: true // optional - faster if false
+ }
+});
+
+// result.ast contains native Uglify AST
+// result.code contains the minified code in string form.
+```
+
+### Working with Uglify AST
+
+Transversal and transformation of the native AST can be performed through
+[`TreeWalker`](https://github.com/mishoo/UglifyJS/blob/master/lib/ast.js) and
+[`TreeTransformer`](https://github.com/mishoo/UglifyJS/blob/master/lib/transform.js)
+respectively.
+
+### ESTree / SpiderMonkey AST
+
+UglifyJS has its own abstract syntax tree format; for
+[practical reasons](http://lisperator.net/blog/uglifyjs-why-not-switching-to-spidermonkey-ast/)
+we can't easily change to using the SpiderMonkey AST internally. However,
+UglifyJS now has a converter which can import a SpiderMonkey AST.
+
+For example [Acorn][acorn] is a super-fast parser that produces a
+SpiderMonkey AST. It has a small CLI utility that parses one file and dumps
+the AST in JSON on the standard output. To use UglifyJS to mangle and
+compress that:
+
+ acorn file.js | uglifyjs -p spidermonkey -m -c
+
+The `-p spidermonkey` option tells UglifyJS that all input files are not
+JavaScript, but JS code described in SpiderMonkey AST in JSON. Therefore we
+don't use our own parser in this case, but just transform that AST into our
+internal AST.
+
+### Use Acorn for parsing
+
+More for fun, I added the `-p acorn` option which will use Acorn to do all
+the parsing. If you pass this option, UglifyJS will `require("acorn")`.
+
+Acorn is really fast (e.g. 250ms instead of 380ms on some 650K code), but
+converting the SpiderMonkey tree that Acorn produces takes another 150ms so
+in total it's a bit more than just using UglifyJS's own parser.

+
+### Uglify Fast Minify Mode
+
+It's not well known, but whitespace removal and symbol mangling accounts
+for 95% of the size reduction in minified code for most JavaScript - not
+elaborate code transforms. One can simply disable `compress` to speed up
+Uglify builds by 3 to 5 times.
+
+| d3.js | minify size | gzip size | minify time (seconds) |
+| --- | ---: | ---: | ---: |
+| original | 511,371 | 119,932 | - |
+| uglify-js@3.13.0 mangle=false, compress=false | 363,988 | 95,695 | 0.56 |
+| uglify-js@3.13.0 mangle=true, compress=false | 253,305 | 81,281 | 0.99 |
+| uglify-js@3.13.0 mangle=true, compress=true | 244,436 | 79,854 | 5.30 |
+
+To enable fast minify mode from the CLI use:
+```
+uglifyjs file.js -m
+```
+To enable fast minify mode with the API use:
+```javascript
+UglifyJS.minify(code, { compress: false, mangle: true });
+```
+
+### Source maps and debugging
+
+Various `compress` transforms that simplify, rearrange, inline and remove code
+are known to have an adverse effect on debugging with source maps. This is
+expected as code is optimized and mappings are often simply not possible as
+some code no longer exists. For highest fidelity in source map debugging
+disable the Uglify `compress` option and just use `mangle`.
+
+### Compiler assumptions
+
+To allow for better optimizations, the compiler makes various assumptions:
+
+- The code does not rely on preserving its runtime performance characteristics.
+ Typically uglified code will run faster due to less instructions and easier
+ inlining, but may be slower on rare occasions for a specific platform, e.g.
+ see [`reduce_funcs`](#compress-options).
+- `.toString()` and `.valueOf()` don't have side effects, and for built-in
+ objects they have not been overridden.
+- `undefined`, `NaN` and `Infinity` have not been externally redefined.
+- `arguments.callee`, `arguments.caller` and `Function.prototype.caller` are not used.
+- The code doesn't expect the contents of `Function.prototype.toString()` or
+ `Error.prototype.stack` to be anything in particular.
+- Getting and setting properties on a plain object does not cause other side effects
+ (using `.watch()` or `Proxy`).
+- Object properties can be added, removed and modified (not prevented with
+ `Object.defineProperty()`, `Object.defineProperties()`, `Object.freeze()`,
+ `Object.preventExtensions()` or `Object.seal()`).
+- Earlier versions of JavaScript will throw `SyntaxError` with the following:
+ ```javascript
+ ({
+ p: 42,
+ get p() {},
+ });
+ // SyntaxError: Object literal may not have data and accessor property with
+ // the same name
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Iteration order of keys over an object which contains spread syntax in later
+ versions of Chrome and Node.js may be altered.
+- When `toplevel` is enabled, UglifyJS effectively assumes input code is wrapped
+ within `function(){ ... }`, thus forbids aliasing of declared global variables:
+ ```javascript
+ A = "FAIL";
+ var B = "FAIL";
+ // can be `global`, `self`, `window` etc.
+ var top = function() {
+ return this;
+ }();
+ // "PASS"
+ top.A = "PASS";
+ console.log(A);
+ // "FAIL" after compress and/or mangle
+ top.B = "PASS";
+ console.log(B);
+ ```
+- Use of `arguments` alongside destructuring as function parameters, e.g.
+ `function({}, arguments) {}` will result in `SyntaxError` in earlier versions
+ of Chrome and Node.js - UglifyJS may modify the input which in turn may
+ suppress those errors.
+- Earlier versions of Chrome and Node.js will throw `ReferenceError` with the
+ following:
+ ```javascript
+ var a;
+ try {
+ throw 42;
+ } catch ({
+ [a]: b,
+ // ReferenceError: a is not defined
+ }) {
+ let a;
+ }
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Later versions of JavaScript will throw `SyntaxError` with the following:
+ ```javascript
+ a => {
+ let a;
+ };
+ // SyntaxError: Identifier 'a' has already been declared
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Later versions of JavaScript will throw `SyntaxError` with the following:
+ ```javascript
+ try {
+ // ...
+ } catch ({ message: a }) {
+ var a;
+ }
+ // SyntaxError: Identifier 'a' has already been declared
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Some versions of Chrome and Node.js will throw `ReferenceError` with the
+ following:
+ ```javascript
+ console.log(((a, b = function() {
+ return a;
+ // ReferenceError: a is not defined
+ }()) => b)());
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Some arithmetic operations with `BigInt` may throw `TypeError`:
+ ```javascript
+ 1n + 1;
+ // TypeError: can't convert BigInt to number
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Some versions of JavaScript will throw `SyntaxError` with the
+ following:
+ ```javascript
+ console.log(String.raw`\uFo`);
+ // SyntaxError: Invalid Unicode escape sequence
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Some versions of JavaScript will throw `SyntaxError` with the
+ following:
+ ```javascript
+ try {} catch (e) {
+ for (var e of []);
+ }
+ // SyntaxError: Identifier 'e' has already been declared
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Some versions of Chrome and Node.js will give incorrect results with the
+ following:
+ ```javascript
+ console.log({
+ ...{
+ set 42(v) {},
+ 42: "PASS",
+ },
+ });
+ // Expected: { '42': 'PASS' }
+ // Actual: { '42': undefined }
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Later versions of JavaScript will throw `SyntaxError` with the following:
+ ```javascript
+ var await;
+ async function f() {
+ class A {
+ static p = await;
+ }
+ }
+ // SyntaxError: Unexpected reserved word
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Later versions of JavaScript will throw `SyntaxError` with the following:
+ ```javascript
+ var async;
+ for (async of []);
+ // SyntaxError: The left-hand side of a for-of loop may not be 'async'.
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Later versions of Chrome and Node.js will give incorrect results with the
+ following:
+ ```javascript
+ console.log({
+ ...console,
+ get 42() {
+ return "FAIL";
+ },
+ [42]: "PASS",
+ }[42]);
+ // Expected: "PASS"
+ // Actual: "FAIL"
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.
+- Earlier versions of JavaScript will throw `TypeError` with the following:
+ ```javascript
+ (function() {
+ {
+ const a = "foo";
+ }
+ {
+ const a = "bar";
+ }
+ })();
+ // TypeError: const 'a' has already been declared
+ ```
+ UglifyJS may modify the input which in turn may suppress those errors.

+# Upper Case
+
+[![NPM version][npm-image]][npm-url]
+[![NPM downloads][downloads-image]][downloads-url]
+[![Build status][travis-image]][travis-url]
+[![Test coverage][coveralls-image]][coveralls-url]
+
+Upper case a string.
+
+Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a `toString` property, numbers and booleans. Empty values (`null` and `undefined`) will result in an empty string.
+
+## Installation
+
+```
+npm install upper-case --save
+```
+
+## Usage
+
+```js
+var upperCase = require('upper-case')
+
+upperCase(null) //=> ""
+upperCase('string') //=> "STRING"
+upperCase('string', 'tr') //=> "STRİNG"
+
+upperCase({ toString: function () { return 'test' } }) //=> "TEST"
+```
