gulp-minify-work v2.1.1

gulp-minify

Minify JavaScript with uglify-es.

Note

The latest version of gulp-minify is using uglify-es to minify files, this may cause some incompatible issues with earlier language versions for now, see https://github.com/hustxiaoc/gulp-minify/issues/27.

So gulp-minify@es5 is for the earlier language versions if your project is not ready for the ECMAScript 6 yet.

Installation

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

npm install --save-dev gulp-minify

Usage

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

gulp.task('compress', function() {
  gulp.src('lib/*.js')
    .pipe(minify({
        ext:{
            src:'-debug.js',
            min:'.js'
        },
        exclude: ['tasks'],
        ignoreFiles: ['.combo.js', '-min.js']
    }))
    .pipe(gulp.dest('dist'))
});

Options

• ext An object that specifies output source and minified file extensions.

  	- `source`
  
  		The suffix string of the filenames that output source files ends with.
  
  	- `min`
  
  		- When string:	The suffix string of the filenames that output minified files ends with.
  		- When Array:	The regex expressions to be replaced with input filenames. For example: `[/\.(.*)-source\.js$/, '$1.js']`

• exclude

  Will not minify files in the dirs.

• noSource Will not output the source code in the dest dirs.

• ignoreFiles

  Will not minify files which matches the pattern.

• mangle

  	Pass `false` to skip mangling names.

• output

  	Pass an object if you wish to specify additional [output
  	options](http://lisperator.net/uglifyjs/codegen). The defaults are
  	optimized for best compression.

• compress

  	Pass an object to specify custom [compressor
  	options](http://lisperator.net/uglifyjs/compress). 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`.
