Options

You can use all command line options in UglifyJs2.

• String command line option

  uglify('-c -m --screw-ie8')

• Array command line option

  uglify(['-c', '-m', '--screw-ie8'])

• Hash option

  uglify({preCommand: 'license.js', command: '-c -m --screw-ie8'})

  By setting output option, you can output file directly.

  uglify({command: '-c', output: '/home/test/output.js'})

  By setting uglifyjs option, you can use custom uglifyjs path.

  uglify({command: '-c', uglifyjs: '/home/node_modules/.bin/uglifyjs'})

  If you have an error 'Permission Denied' in 'gulp-uglify-cli', please try to use tmp option which is accessible file path.

  uglify({command: '-c', tmp: '/tmp/_tmp.js'})
