# @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
})
]
};
```
