NAME
uglifyjs - JavaScript parser, mangler/compressor and beautifier toolkit
DESCRIPTION
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
--help Show help [boolean]
--source-map
Specify an output file where to generate source map. [string]
--source-map-root
The path to the original source to be included in the source map. [string]
--source-map-url
The path to the source map to be added in //# sourceMappingURL. Defaults to the value passed with
--source-map. [string]
--source-map-inline
Write base64-encoded source map to the end of js output. Disabled by default [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. [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. [boolean]
--support-ie8
Support non-standard Internet Explorer 6/7/8 javascript. [boolean]
--expr Parse a single expression, rather than a program (for parsing JSON) [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.
[string]
-o, --output
Output file (default STDOUT).
-b, --beautify
Beautify output/specify output options. [string]
-m, --mangle
Mangle names/pass mangler options. [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.
[string]
-d, --define
Global definitions [string]
-e, --enclose
Embed everything in a big function, with a configurable parameter/argument list. [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.
[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. [boolean]
--acorn
Use Acorn for parsing. [boolean]
--spidermonkey
Assume input files are SpiderMonkey AST format (as JSON). [boolean]
--self Build itself (UglifyJS2) as a library (implies --wrap=UglifyJS --export-all) [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. [string]
--export-all
Only used when --wrap, this tells UglifyJS to add code to automatically export all globals.
[boolean]
--lint Display some scope warnings [boolean]
-v, --verbose
Verbose [boolean]
-V, --version
Show version number [boolean]
--noerr
Don't throw an error for unknown options in -c, -b or -m. [boolean]
--bare-returns
Allow return outside of functions. Useful when minifying CommonJS modules. [boolean]
--keep-fnames
Do not mangle/drop function names. Useful for code relying on Function.prototype.name.
[boolean]
--reserved-file
File containing reserved names [array]
--reserve-domprops
Make (most?) DOM properties reserved for --mangle-props [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 [string]
--pure-funcs
List of functions that can be safely removed if their return value is not used [array]
--dump-spidermonkey-ast
Dump SpiderMonkey AST to stdout. [boolean]
--wrap-iife
Wrap IIFEs in parenthesis. Note: this disables the negate_iife compression option [boolean]
-q, --quotes
Quote style (0 - auto, 1 - single, 2 - double, 3 - original)
