gulp-uglyfly

Minify JavaScript with UglyflyJS (fork of UglifyJS2)

About

This gulp package is forked from Terin Stock's gulp-uglify. It uses UglyflyJS instead of UglifyJS2 to minify javascript.

This fork should handle sourcemaps/filenames/streams properly.

It is also able to parallelize the transforms if there are multiple cpus.

Installation

Install package with NPM and add it to your development dependencies:

npm install --save-dev gulp-uglyfly

Usage

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

gulp.task('compress', function() {
  gulp.src('lib/*.js')
    .pipe(uglyfly())
    .pipe(gulp.dest('dist'))
});

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 uglyfly function any of the options listed here to modify UglyflyJS's behavior.
