| # @rollup/plugin-terser | |
| 🍣 A Rollup plugin to generate a minified bundle with terser. | |
| ## Requirements | |
| This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v14.0.0+) and Rollup v2.0+. | |
| ## Install | |
| Using npm: | |
| ```console | |
| npm install @rollup/plugin-terser --save-dev | |
| ``` | |
| ## Usage | |
| Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin: | |
| ```typescript | |
| import terser from '@rollup/plugin-terser'; | |
| export default { | |
| input: 'src/index.js', | |
| output: { | |
| dir: 'output', | |
| format: 'cjs' | |
| }, | |
| plugins: [terser()] | |
| }; | |
| ``` | |
| Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api). | |
| ## Options | |
| The plugin accepts a terser [Options](https://github.com/terser/terser#minify-options) object as input parameter, | |
| to modify the default behaviour. | |
| In addition to the `terser` options, it is also possible to provide the following options: | |
| ### `maxWorkers` | |
| Type: `Number`<br> | |
| Default: `undefined` | |
| Instructs the plugin to use a specific amount of cpu threads. | |
| ```typescript | |
| import terser from '@rollup/plugin-terser'; | |
| export default { | |
| input: 'src/index.js', | |
| output: { | |
| dir: 'output', | |
| format: 'cjs' | |
| }, | |
| plugins: [ | |
| terser({ | |
| maxWorkers: 4 | |
| }) | |
| ] | |
| }; | |
| ``` | |
