uglify-js - manual page for uglify-js 2.8.29
DESCRIPTION
bin/uglifyjs input1.js [input2.js ...] [options] Use a single dash to read input from the standard input. NOTE: by default there is no mangling/compression. Without [options] it will simply parse input files and dump the AST with whitespace and comments discarded. To achieve compression and mangling you need to use `-c` and `-m`.
OPTIONS
--source-map Specify an output file where to generate source map. This parameter is a string. --source-map-root The path to the original source to be included in the source map. This parameter is a string. --source-map-url The path to the source map to be added in //# sourceMappingURL. Defaults to the value passed with --source-map. This parameter is a string. --source-map-inline Write base64-encoded source map to the end of js output. Disabled by default This parameter is a boolean. --source-map-include-sources Pass this flag if you want to include the content of source files in the source map as sourcesContent property. This parameter is a boolean. --in-source-map Input source map, useful if you're compressing JS that was generated from some other original code. --screw-ie8 Do not support Internet Explorer 6/7/8. This flag is enabled by default. This parameter is a boolean. --support-ie8 Support non-standard Internet Explorer 6/7/8 javascript. This parameter is a boolean. --expr Parse a single expression, rather than a program (for parsing JSON) This parameter is a boolean. -p, --prefix Skip prefix for original filenames that appear in source maps. For example -p 3 will drop 3 directories from file names and ensure they are relative paths. You can also specify -p relative, which will make UglifyJS figure out itself the relative paths between original sources, the source map and the output file. This parameter is a string. -o, --output Output file (default STDOUT). -b, --beautify Beautify output/specify output options. This parameter is a string. -m, --mangle Mangle names/pass mangler options. This parameter is a string. -r, --reserved Reserved names to exclude from mangling. -c, --compress Enable compressor/pass compressor options. Pass options like -c hoist_vars=false,if_return=false. Use -c with no argument to use the default compression options. This parameter is a string. -d, --define Global definitions This parameter is a string. -e, --enclose Embed everything in a big function, with a configurable parameter/argument list. This parameter is a string. --comments 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. This parameter is a string. --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. --stats Display operations run time on STDERR. This parameter is a boolean. --acorn Use Acorn for parsing. This parameter is a boolean. --spidermonkey Assume input files are SpiderMonkey AST format (as JSON). This parameter is a boolean. --self Build itself (UglifyJS2) as a library (implies --wrap=UglifyJS --export-all) This parameter is a boolean. --wrap 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. This parameter is a string. --export-all Only used when --wrap, this tells UglifyJS to add code to automatically export all globals. This parameter is a boolean. --lint Display some scope warnings This parameter is a boolean. -v, --verbose Verbose This parameter is a boolean. -V, --version Print version number and exit. This parameter is a boolean. --noerr Don't throw an error for unknown options in -c, -b or -m. This parameter is a boolean. --bare-returns Allow return outside of functions. Useful when minifying CommonJS modules. This parameter is a boolean. --keep-fnames Do not mangle/drop function names. Useful for code relying on Function.prototype.name. This parameter is a boolean. --reserved-file File containing reserved names This parameter is an array. --reserve-domprops Make (most?) DOM properties reserved for --mangle-props This parameter is a boolean. --mangle-props Mangle property names (0 - disabled, 1 - mangle all properties, 2 - mangle unquoted properies) --mangle-regex Only mangle property names matching the regex --name-cache File to hold mangled names mappings This parameter is a string. --pure-funcs List of functions that can be safely removed if their return value is not used This parameter is an array. --dump-spidermonkey-ast Dump SpiderMonkey AST to stdout. This parameter is a boolean. --wrap-iife Wrap IIFEs in parenthesis. Note: this disables the negate_iife compression option This parameter is a boolean. --help Show help This parameter is a boolean. -q, --quotes Quote style (0 - auto, 1 - single, 2 - double, 3 - original)
