gulp-minify

Minify JavaScript with terser.

Build Status NPM version

Note

The latest version of gulp-minify is using terser 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

Basic usage: the following minifies every *.js and *.mjs files to *-min.js and *-min.mjs respectively. Note that the original files are preserved.

const minify = require('gulp-minify');
 
gulp.task('compress', function() {
  gulp.src(['lib/*.js', 'lib/*.mjs'])
    .pipe(minify())
    .pipe(gulp.dest('dist'))
});

Options can be added to control more finely what's happening, for example:

const 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 src and minified file extensions.

    • src

    • 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

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

  • ignoreFiles

    Will not minify files which matches the pattern.
