# rollup-plugin-typescript
![travis-ci](https://travis-ci.org/rollup/rollup-plugin-typescript.svg?branch=master)

Seamless integration between Rollup and Typescript.

## Why?
See [rollup-plugin-babel](https://github.com/rollup/rollup-plugin-babel).

## Installation

```bash
npm install --save-dev rollup-plugin-typescript
```

## Usage

```js
import typescript from 'rollup-plugin-typescript';

export default {
  entry: 'main.ts',

  plugins: [
    typescript()
  ]
}
```

All options are as per the [Typescript's Compiler Options](https://github.com/Microsoft/TypeScript/wiki/Compiler-Options), except `options.include` and `options.exclude` (each a minimatch pattern, or array of minimatch patterns), which determine which files are transpiled by Typescript (by default, all files are transpiled).

## Issues

TypeScript 1.6.2 isn't able to transpile to ES5 while preserving ES2015 modules. That's why we use a prerelease of [TypeScript 1.7.0](https://github.com/Microsoft/TypeScript/wiki/Roadmap#17) for ease of use. :rocket: This option can be easily be overridden.

```js
import typescript from 'rollup-plugin-typescript';
import * as ts from 'typescript';

export default {
  entry: 'main.ts',

  plugins: [
    typescript({
      target: ts.ScriptTarget.ES6
    })
  ]
}
```
