Once you're familiar with that process, you may install this plugin with this command:\n\n```shell\nnpm install grunt-contrib-uglify --save-dev\n```\n\nOnce the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:\n\n```js\ngrunt.loadNpmTasks('grunt-contrib-uglify');\n```\n\n\n\n\n## Uglify task\n_Run this task with the `grunt uglify` command._\n\nTask targets, files and options may be specified according to the grunt [Configuring tasks](http://gruntjs.com/configuring-tasks) guide.\n\n### Migrating from 2.x to 3.x\n\nVersion `3.x` introduced changes to configuring source maps. Accordingly, if you don't use the source map options you should be able to upgrade seamlessly. If you do use source maps, see below.\n\n#### Removed options\n\n`sourceMapRoot` - The location of your sources is now calculated for you when `sourceMap` is set to `true` \n`sourceMapPrefix` - No longer necessary for the above reason \n`sourceMappingURL` - Once again, this is calculated automatically\n\n#### Changed options\n\n`sourceMap` - Only accepts a `Boolean` value. Generates a map with a default name for you \n\n#### New options\n\n`sourceMapName` - Accepts a string or function to change the location or name of your map\n`sourceMapIncludeSources` - Embed the content of your source files directly into the map\n`expression` - Accepts a `Boolean` value. Parse a single expression (JSON or single functions)\n\n### Options\n\nThis task primarily delegates to [UglifyJS2][], so please consider the [UglifyJS documentation][] as required reading for advanced configuration.\n\n[UglifyJS2]: https://github.com/mishoo/UglifyJS2\n[UglifyJS documentation]: http://lisperator.net/uglifyjs/\n\n#### mangle\nType: `Boolean` `Object` \nDefault: `{}`\n\nTurn on or off mangling with default options. If an `Object` is specified, it is passed directly to `ast.mangle_names()` *and* `ast.compute_char_frequency()` (mimicking command line behavior).\n\n#### compress\nType: `Boolean` `Object` \nDefault: `{}`\n\nTurn on or off source compression with default options. If an `Object` is specified, it is passed as options to `UglifyJS.Compressor()`.\n\n#### beautify\nType: `Boolean` `Object` \nDefault: `false`\n\nTurns on beautification of the generated source code. An `Object` will be merged and passed with the options sent to `UglifyJS.OutputStream()`\n\n###### expression\nType: `Boolean`\nDefault: `false`\n\nParse a single expression, rather than a program (for parsing JSON)\n\n#### report\nChoices: `'min'`, `'gzip'` \nDefault: `'min'`\n\nEither report only minification result or report minification and gzip results.\nThis is useful to see exactly how well clean-css is performing but using `'gzip'` will make the task take 5-10x longer to complete. [Example output](https://github.com/sindresorhus/maxmin#readme).\n\n#### sourceMap\nType: `Boolean` \nDefault: `false`\n\nIf `true`, a source map file will be generated in the same directory as the `dest` file. By default it will have the same basename as the `dest` file, but with a `.map` extension.\n\n#### sourceMapName\nType: `String` `Function` \nDefault: `undefined`\n\nTo customize the name or location of the generated source map, pass a string to indicate where to write the source map to. If a function is provided, the uglify destination is passed as the argument and the return value will be used as the file name.\n\n#### sourceMapIn\nType: `String` `Function` \nDefault: `undefined`\n\nThe location of an input source map from an earlier compilation, e.g. from CoffeeScript. If a function is provided, the\nuglify source is passed as the argument and the return value will be used as the sourceMap name. This only makes sense\nwhen there's one source file.\n\n#### sourceMapIncludeSources\nType: `Boolean`\nDefault: `false`\n\nPass this flag if you want to include the content of source files in the source map as sourcesContent property.\n\n###### enclose\nType: `Object` \nDefault: `undefined`\n\nWrap all of the code in a closure with a configurable arguments/parameters list.\nEach key-value pair in the `enclose` object is effectively an argument-parameter pair.\n\n#### wrap\nType: `String` \nDefault: `undefined`\n\nWrap all of the code in a closure, an easy way to make sure nothing is leaking.\nFor variables that need to be public `exports` and `global` variables are made available.\nThe value of wrap is the global variable exports will be available as.\n\n#### exportAll\nType: `Boolean` \nDefault: `false`\n\nWhen using `wrap` this will make all global functions and variables available via the export variable.\n\n#### preserveComments\nType: `Boolean` `String` `Function` \nDefault: `undefined` \nOptions: `false` `'all'` `'some'`\n\nTurn on preservation of comments.\n\n- `false` will strip all comments\n- `'all'` will preserve all comments in code blocks that have not been squashed or dropped\n- `'some'` will preserve all comments that start with a bang (`!`) or include a closure compiler style directive (`@preserve` `@license` `@cc_on`)\n- `Function` specify your own comment preservation function. You will be passed the current node and the current comment and are expected to return either `true` or `false`\n\n#### banner\nType: `String` \nDefault: empty string\n\nThis string will be prepended to the minified output. Template strings (e.g. `<%= config.value %>` will be expanded automatically.\n\n#### footer\nType: `String` \nDefault: empty string\n\nThis string will be appended to the minified output. Template strings (e.g. `<%= config.value %>` will be expanded automatically.\n\n### Usage examples\n\n#### Basic compression\n\nThis configuration will compress and mangle the input files using the default options.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n my_target: {\n files: {\n 'dest/output.min.js': ['src/input1.js', 'src/input2.js']\n }\n }\n }\n});\n```\n\n#### No mangling\n\nSpecify `mangle: false` to prevent changes to your variable and function names.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n options: {\n mangle: false\n },\n my_target: {\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n }\n }\n});\n```\n\n#### Reserved identifiers\n\nYou can specify identifiers to leave untouched with an `except` array in the `mangle` options.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n options: {\n mangle: {\n except: ['jQuery', 'Backbone']\n }\n },\n my_target: {\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n }\n }\n});\n```\n\n#### Source maps\n\nGenerate a source map by setting the `sourceMap` option to `true`. The generated\nsource map will be in the same directory as the destination file. Its name will be the\nbasename of the destination file with a `.map` extension. Override these\ndefaults with the `sourceMapName` attribute.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n my_target: {\n options: {\n sourceMap: true,\n sourceMapName: 'path/to/sourcemap.map'\n },\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n }\n }\n});\n```\n\n#### Advanced source maps\n\nSet the `sourceMapIncludeSources` option to `true` to embed your sources directly into the map. To include\na source map from a previous compilation pass it as the value of the `sourceMapIn` option.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n my_target: {\n options: {\n sourceMap: true,\n sourceMapIncludeSources: true,\n sourceMapIn: 'example/coffeescript-sourcemap.js', // input sourcemap from a previous compilation\n },\n files: {\n 'dest/output.min.js': ['src/input.js'],\n },\n },\n },\n});\n```\n\nRefer to the [UglifyJS SourceMap Documentation](http://lisperator.net/uglifyjs/codegen#source-map) for more information.\n\n\n#### Discard console.* functions\n\nSpecify `drop_console: true` as part of the `compress` options to discard calls to `console.*` functions.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n options: {\n compress: {\n drop_console: true\n }\n },\n my_target: {\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n }\n }\n});\n```\n\n#### Beautify\n\nSpecify `beautify: true` to beautify your code for debugging/troubleshooting purposes.\nPass an object to manually configure any other output options passed directly to `UglifyJS.OutputStream()`.\n\nSee [UglifyJS Codegen documentation](http://lisperator.net/uglifyjs/codegen) for more information.\n\n_Note that manual configuration will require you to explicitly set `beautify: true` if you want traditional, beautified output._\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n my_target: {\n options: {\n beautify: true\n },\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n },\n my_advanced_target: {\n options: {\n beautify: {\n width: 80,\n beautify: true\n }\n },\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n }\n }\n});\n```\n\n#### Banner comments\n\nIn this example, running `grunt uglify:my_target` will prepend a banner created by interpolating the `banner` template string with the config object. Here, those properties are the values imported from the `package.json` file (which are available via the `pkg` config property) plus today's date.\n\n_Note: you don't have to use an external JSON file. It's also valid to create the `pkg` object inline in the config. That being said, if you already have a JSON file, you might as well reference it._\n\n```js\n// Project configuration.\ngrunt.initConfig({\n pkg: grunt.file.readJSON('package.json'),\n uglify: {\n options: {\n banner: '/*! <%= pkg.name %> - v<%= pkg.version %> - ' +\n '<%= grunt.template.today(\"yyyy-mm-dd\") %> */'\n },\n my_target: {\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n }\n }\n});\n```\n\n#### Conditional compilation\n\nYou can also enable UglifyJS conditional compilation. This is commonly used to remove debug code blocks for production builds.\n\nSee [UglifyJS global definitions documentation](http://lisperator.net/uglifyjs/compress#global-defs) for more information.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n options: {\n compress: {\n global_defs: {\n \"DEBUG\": false\n },\n dead_code: true\n }\n },\n my_target: {\n files: {\n 'dest/output.min.js': ['src/input.js']\n }\n }\n }\n});\n```\n#### Compiling all files in a folder dynamically\n\nThis configuration will compress and mangle the files dynamically.\n\n```js\n// Project configuration.\ngrunt.initConfig({\n uglify: {\n my_target: {\n files: [{\n expand: true,\n cwd: 'src/js',\n src: '**/*.js',\n dest: 'dest/js'\n }]\n }\n }\n});\n```\n\n\n## Release History\n\n * 2014-06-11 v0.5.0 added option \"expression\" to uglify json and single functions.
