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