Traceur Loader for Webpack

==========================

A [Webpack][] loader for transpiling ES6-compatible code to ES5-compatible code using Google's [Traceur][] compiler.

## Installation

```sh

npm install webpack-traceur-loader

```

## Usage

### Inline

Requiring files inline:

```javascript

// Simple inline usage

require('webpack-traceur!./src/index');

// More advanced version; include the Traceur runtime

require('webpack-traceur!./src/index?runtime');

```

[Documentation: Using Loaders][]

### Recommended Configuration

In your `webpack.config.js` file:

```js

module.exports = {

  module: {

    loaders: [

      // Transpile any JavaScript file:

      { test: /\.js$/, loader: 'webpack-traceur' },

      // Or only those with a specific suffix:

      { test: /\.es6\.js$/, loader: 'webpack-traceur' },

      // Include the Traceur runtime:

      { test: /\.es6\.js$/, loader: 'webpack-traceur?runtime' },

      // ...And any other Traceur option you like:

      { test: /\.es6\.js$/, loader: 'webpack-traceur?runtime&sourceMaps&experimental' }

    ]

  }

};

```

### Settings

You can set default settings for Traceur in `webpack.config.js`, or in a `require` statement as a querystring.

#### List of Settings

`runtime`: Set to `true` to disable inclusion of the Traceur runtime library in your built file. Defaults to `false`.

All other options are passed directly to to the Traceur compiler. See [this list][Traceur options] for a list of all Traceur options, and see [this guide][ES6 options] for example usages of ES6 features supported by Traceur.

## Demo

See the [`test/demo-app`](test/demo-app) directory for demo of the loader.
