# @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
    })
  ]
};
```
