Usage

var uglify = require('gulp-uglify');

Options

  • mangle

    Pass false to skip mangling names.

  • output

    Pass an object if you wish to specify additional output options. The defaults are optimized for best compression.

  • compress

    Pass an object to specify custom compressor options. Pass false to skip compression completely.

  • preserveComments

    A convenience option for options.output.comments. Defaults to preserving no comments.

    • all

      Preserve all comments in code blocks

    • some

      Preserve comments that start with a bang (!) or include a Closure Compiler directive (@preserve, @license, @cc_on)

    • 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.

You can also pass the uglify function any of the options listed here to modify UglifyJS's behavior.

Source Maps

You can have UglifyJS’s generated source maps emitted on the stream by passing true for the outSourceMap option. The file object’s path will be based on the input file’s, with ‘.map’ appended.

Input source maps are no supported by this plugin at this time.
