# @rollup/plugin-swc

🍣 A Rollup plugin to transpile TypeScript/JavaScript with the speedy-web-compiler (swc).

The plugin makes it possible to avoid the usage of `@rollup/plugin-babel` and `@rollup/plugin-typescript`.
It is also blazingly fast 🔥 (between 20 - 70 times faster than Babel depending on how many cpu cores are used).

## Requirements

This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v14.0.0+) and Rollup v3.0+.

## Install

Using npm:

```console
npm install @swc/core @rollup/plugin-swc --save-dev
```

## Usage

Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:

```typescript
import swc from '@rollup/plugin-swc';

export default {
  input: 'src/index.js',
  output: {
    dir: 'output',
    format: 'cjs'
  },
  plugins: [swc()]
};
```

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 an object as input parameter to modify the default behaviour.

### `swc`

- Type: [Options](https://swc.rs/docs/configuration/swcrc)
- Default: `undefined`

```typescript
import type { Options as SWCOptions } from '@swc/core';

declare type Options = {
  swc?: SWCOptions;
};
```

### `exclude`

- Type: `String` | `Array[...String]`
- Default: `null`

A [picomatch pattern](https://github.com/micromatch/picomatch),
or array of patterns, which specifies the files in the build the plugin should _ignore_. By default no files are ignored.

### `include`

- Type: `String` | `Array[...String]`
- Default: `null`

A [picomatch pattern](https://github.com/micromatch/picomatch),
or array of patterns, which specifies the files in the build the plugin should operate on. By default all files are targeted.

## Alternatives

Alternative transpiler/transformer, which are also officially offered, are [Babel](https://www.npmjs.com/package/@rollup/plugin-babel) and [Sucrase](https://www.npmjs.com/package/@rollup/plugin-sucrase).
Both Babel and Sucrase are written in JavaScript, whereas the core of SWC is written in Rust. In addition, Sucrase transforms code to ES6+, whereas babel and SWC also support ES3 upwards.
