UglifyJS Webpack Plugin

This plugin uses UglifyJS v3 to minify your JavaScript

ℹ️ webpack contains the same plugin under webpack.optimize.UglifyJsPlugin. The documentation is valid apart from the installation instructions

Install

1npm i -D uglifyjs-webpack-plugin

Usage

webpack.config.js

1const UglifyJSPlugin = require('uglifyjs-webpack-plugin')
2
3module.exports = {
4  plugins: [
5    new UglifyJSPlugin()
6  ]
7}

Options

Name	Type	Default	Description
`test`	`{RegExp\|Array<RegExp>}`	`/.js($\|?)/i`	Test to match files against
`include`	`{RegExp\|Array<RegExp>}`	`undefined`	Files to `include`
`exclude`	`{RegExp\|Array<RegExp>}`	`undefined`	Files to `exclude`
`parallel`	`{Boolean\|Object}`	`false`	Use multi-process parallel running and file cache to improve the build speed
`sourceMap`	`{Boolean}`	`false`	Use source maps to map error message locations to modules (This slows down the compilation) ⚠️ `cheap-source-map` options don't work with this plugin
`uglifyOptions`	`{Object}`	`{...defaults}`	`uglify` Options
`extractComments`	`{Boolean\|RegExp\|Function<(node, comment) -> {Boolean\|Object}>}`	`false`	Whether comments shall be extracted to a separate file, (see details (`webpack >= 2.3.0`)
`warningsFilter`	`{Function(source) -> {Boolean}}`	``	Allow to filter uglify warnings

`test`

webpack.config.js

1[
2  new UglifyJSPlugin({
3    test: /\.js($&#124;\?)/i
4  })
5]

`include`

webpack.config.js

1[
2  new UglifyJSPlugin({
3    include: /\/includes/
4  })
5]

`exclude`

webpack.config.js

1[
2  new UglifyJSPlugin({
3    exclude: /\/excludes/
4  })
5]

`parallel`

webpack.config.js

1[
2  new UglifyJSPlugin({
3    parallel: true
4  })
5]

Name	Type	Default	Description
`cache`	`{Boolean}`	`node_modules/.cache/uglifyjs-webpack-plugin`	Enable file caching
`workers`	`{Boolean\|Object}`	`os.cpus().length - 1`	Number of concurrent runs, default is the `maximum`

webpack.config.js

1[
2  new UglifyJSPlugin({
3    parallel: {
4      cache: true
5      workers: 2 // for e.g
6    }
7  })
8]

ℹ️ Parallelization can speedup your build significantly and is therefore highly recommended

`sourceMap`

webpack.config.js

1[
2  new UglifyJSPlugin({
3    sourceMap: true
4  })
5]

⚠️ cheap-source-map options don't work with this plugin

`uglifyOptions`

Name	Type	Default	Description
`ie8`	`{Boolean}`	`false`	Enable IE8 Support
`ecma`	`{Number}`	`undefined`	Supported ECMAScript Version (`5`, `6`, `7` or `8`). Affects `parse`, `compress` && `output` options
`parse`	`{Object}`	`{}`	Additional Parse Options
`mangle`	`{Boolean\|Object}`	`true`	Enable Name Mangling (See Mangle Properties for advanced setups, use with ⚠️)
`output`	`{Object}`	`{}`	Additional Output Options (The defaults are optimized for best compression)
`compress`	`{Boolean\|Object}`	`true`	Additional Compress Options
`warnings`	`{Boolean}`	`false`	Display Warnings

webpack.config.js

1[
2  new UglifyJSPlugin({
3    uglifyOptions: {
4      ie8: false,
5      ecma: 8,
6      parse: {...options},
7      mangle: {
8        ...options,
9        properties: {
10          // mangle property options
11        }
12      },
13      output: {
14        comments: false,
15        beautify: false,
16        ...options
17      },
18      compress: {...options},
19      warnings: false
20    }
21  })
22]

`extractComments`

{Boolean}

All comments that normally would be preserved by the comments option will be moved to a separate file. If the original file is named foo.js, then the comments will be stored to foo.js.LICENSE

{RegExp|String} or {Function<(node, comment) -> {Boolean}>}

All comments that match the given expression (resp. are evaluated to true by the function) will be extracted to the separate file. The comments option specifies whether the comment will be preserved, i.e. it is possible to preserve some comments (e.g. annotations) while extracting others or even preserving comments that have been extracted.

{Object}

Name	Type	Default	Description
`condition`	`{Regex\|Function}`	``	Regular Expression or function (see previous point)
`filename`	`{String\|Function}`	`compilation.assets[file]`	The file where the extracted comments will be stored. Can be either a `{String}` or a `{Function<(string) -> {String}>}`, which will be given the original filename. Default is to append the suffix `.LICENSE` to the original filename
`banner`	`{Boolean\|String\|Function}`	`/! For license information please see ${filename}.js.LICENSE /`	The banner text that points to the extracted file and will be added on top of the original file. Can be `false` (no banner), a `{String}`, or a `{Function<(string) -> {String}` that will be called with the filename where extracted comments have been stored. Will be wrapped into comment

`warningsFilter`

webpack.config.js

1[
2  new UglifyJsPlugin({
3    warningsFilter: (src) => true
4  })
