Overview Install Usage Source map options Mangler options Compressor options Beautifier options Support for the SpiderMonkey AST API Reference UglifyJS is a JavaScript parser, minifier, compressor or beautifier toolkit. This page documents the command line utility. For API and internals documentation see my website. There's also an in-browser online demo (for Firefox, Chrome and probably Safari). See full list on github.com First make sure you have installed the latest version of node.js (You may need to restart your computer after this step). From NPM for use as a command line app: From NPM for programmatic use: From Git: See full list on github.com UglifyJS2 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 you want to read from STDIN instead, pass a single dash instead of input files. 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: The available options are: See full list on github.com UglifyJS2 can generate a source map file, which is highly useful for debugging your compressed JavaScript. To get a source map, pass --source-map output.js.map (full path to the file where you want the source map dumped). Additionally you might need --source-map-root to pass the URL where the original files can be found. In case you are passing full paths to input files to UglifyJS, you can use --prefix (-p) to specify the number of directories to drop from the path prefix when declaring files in the source map. For example: 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). See full list on github.com To enable the mangler you need to pass --mangle (-m). The following (comma-separated) options are supported: •toplevel — mangle names declared in the toplevel scope (disabled by default). •eval — mangle names visible in scopes where eval or with are used (disabled by default). When mangling is enabled but you want to prevent certain names from being mangled, you can declare those names with --reserved (-r) — pass a comma-separated list of names. For example: See full list on github.com You need to pass --compress (-c) to enable the compressor. Optionally you can pass a comma-separated list of 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). •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. •properties -- rewrite property access using the dot notation, for example foo["bar"] → foo.bar •dead_code -- remove unreachable code •drop_debugger -- remove debugger; statements •unsafe (default: false) -- apply "unsafe" transformations (discussion below) See full list on github.com 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: •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. •indent-level (default 4) •indent-start (default 0) -- prefix all lines by that many spaces •quote-keys (default false) -- pass true to quote all keys in literal objects •space-colon (default true) -- insert a space after the colon signs See full list on github.com UglifyJS2 has its own abstract syntax tree format; for practical reasons 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 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: See full list on github.com The simple way There's a single toplevel function which combines all the steps. If you don't need additional customization, you might want to go with minify. Example: You can also compress multiple files: To generate a source map: To generate a source map with the fromString option, you can also use an object: Note that the source map is not saved in a file, it's just returned in result.map. The value passed for outSourceMap is only used to set //# sourceMappingURL=out.js.map in result.code. The value of outFileName is only used to set file attribute in source map file. The file attribute in the source map (see the spec) will use outFileName firstly, if it's falsy, then will be deduced from outSourceMap (by removing '.map'). You can set option sourceMapInline to be true and source map will be appended to code. You can also specify sourceRoot property to be included in source map: If you're compressing compiled JavaScript and have a source map for it, you can use the inSourceMap argument: If your input source map is not in a file, you can pass it in as an object using the inSourceMap argument: The inSourceMap is only used if you also request outSourceMap (it makes no sense otherwise). To set the source map url, use the sourceMapUrl option. If you're using the X-SourceMap header instead, you can just set the sourceMapUrl option to false. Defaults to outSourceMap: Other options: •warnings (default false) — pass true to display compressor warnings. •fromString (default false) — if you pass true then you can pass JavaScript source code, rather than file names. •mangle (default true) — pass false to skip mangling names, or pass an object to specify mangling options (see below). •mangleProperties (default false) — pass an object to specify custom mangle property options. •output (default null) — pass an object if you wish to specify additional output options. The defaults are optimized for best compression. •compress (default {}) — pass false to skip compressing entirely. Pass an object to specify custom compressor options. •parse (default {}) — pass an object if you wish to specify some additional parser options. (not all options available... see below) mangle •except - pass an array of identifiers that should be excluded from mangling •toplevel — mangle names declared in the toplevel scope (disabled by default). •eval — mangle names visible in scopes where eval or with are used (disabled by default). •keep_fnames -- default false. Pass true to not mangle function names. Useful for code relying on Function.prototype.name. See also: the keep_fnames compress option. Examples: mangleProperties options •regex — Pass a RegExp to only mangle certain names (maps to the --mangle-regex CLI arguments option) •ignore_quoted – Only mangle unquoted property names (maps to the --mangle-props 2 CLI arguments option) •debug – Mangle names with the original name still present (maps to the --mangle-props-debug CLI arguments option). Defaults to false. Pass an empty string to enable, or a non-empty string to set the suffix. We could add more options to UglifyJS.minify — if you need additional functionality please suggest!
