Seamless integration between Rollup and TypeScript.

## Why?
Because [the origin repository](https://github.com/rollup/rollup-plugin-typescript) hasn’t been maintained for a while.

## Installation

```bash
# with npm
npm install --save-dev rollup-typescript typescript
# with yarn
yarn add typescript rollup-typescript --dev
```

## Usage

```js
// rollup.config.js
import typescript from 'rollup-typescript';

export default {
  input: './main.ts',
  plugins: [
    typescript(),
  ],
}
```

The plugin loads any [`compilerOptions`](http://www.typescriptlang.org/docs/handbook/compiler-options.html) from the `tsconfig.json` file by default. Passing options to the plugin directly overrides those options.

The following options are unique to `rollup-plugin-typescript`:

* `options.include` and `options.exclude` (each a minimatch pattern, or array of minimatch patterns), which determine which files are transpiled by Typescript (all `.ts` and `.tsx` files by default).

* `tsconfig` when set to false, ignores any options specified in the config file

* `typescript` overrides TypeScript used for transpilation

### TypeScript version
This plugin currently requires TypeScript > 2.0. For earlier versions, use version 0.8.1.

## Issues
Emit-less types, see [#28](https://github.com/alexlur/rollup-plugin-typescript/issues/28).
