Traceur Loader for Webpack
==========================

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

Usage

$3

Requiring files inline:

``javascript
// Simple inline usage
require('traceur!./src/index');

// More advanced version; include the Traceur runtime
require('traceur!./src/index?runtime');
`

[Documentation: Using Loaders][]

$3

In your webpack.config.js file:

`js
module.exports = {
module: {
loaders: [
// Transpile any JavaScript file:
{ test: /\.js$/, loader: 'traceur' },

// Or only those with a specific suffix:
{ test: /\.es6\.js$/, loader: 'traceur' },

// Include the Traceur runtime:
{ test: /\.es6\.js$/, loader: 'traceur?runtime' },

// ...And any other Traceur option you like:
{ test: /\.es6\.js$/, loader: 'traceur?runtime&sourceMaps&experimental' }
]
}
};
`

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
