| # @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 |
| }) |
| ] |
| }; |
| ``` |
