       uglify-js - manual page for uglify-js 2.4.15

DESCRIPTION

       /usr/bin/nodejs  ./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.

       --source-map-root
              The path to the original source to be included in the source map.

       --source-map-url
              The path to the source map to be added in //# sourceMappingURL.  Defaults to the value passed with
              --source-map.

       --source-map-include-sources
              Pass  this  flag  if  you  want  to  include  the  content  of  source  files in the source map as
              sourcesContent property.

       --in-source-map
              Input source map, useful if you're compressing JS that was  generated  from  some  other  original
              code.

       --screw-ie8
              Pass  this  flag  if  you  don't  care about full compliance with Internet Explorer 6-8 quirks (by
              default UglifyJS will try to be IE-proof).

       --expr Parse a single expression, rather than a program (for parsing JSON)

       -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.

       -o, --output
              Output file (default STDOUT).

       -b, --beautify
              Beautify output/specify output options.

       -m, --mangle
              Mangle names/pass mangler options.

       -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.

       -d, --define
              Global definitions

       -e, --enclose
              Embed everything in a big function, with a configurable parameter/argument list.

       --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 (needs to start
              with  a  slash)  to  keep only comments that match.  Note that currently not *all* comments can be
              kept when compression is on, because of dead code removal or cascading statements into sequences.

       --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.

       --acorn
              Use Acorn for parsing.

       --spidermonkey
              Assume input files are SpiderMonkey AST format (as JSON).

       --self Build itself (UglifyJS2) as a library (implies --wrap=UglifyJS --export-all)

       --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.

       --export-all
              Only used when --wrap, this tells UglifyJS to add code to automatically export all globals.

       --lint Display some scope warnings

       -v, --verbose
              Verbose

       -V, --version
              Print version number and exit.

       --noerr
              Don't throw an error for unknown options in -c, -b or -m.
