Traceur Loader for Webpack

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

Usage

Inline

Requiring files inline:

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

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

Documentation: Using Loaders

Recommended Configuration

In your webpack.config.js file:

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' }
    ]
  }
};

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 for a list of all Traceur options, and see this guide for example usages of ES6 features supported by Traceur.
