  module: {

    noParse: [

      new RegExp(TRACEUR_RUNTIME)

    ]

  }

  //...

};

```

## Usage

```javascript

// Simple option (does not include Traceur runtime)

require("traceur!./script-file");

// Include Traceur runtime automatically

require("traceur?runtime!./script-file");

// Specify Traceur options

require("traceur?experimental&symbols!./script-file");

// All together now

require("traceur?runtime&symbols!./script-file");

```

### Recommended configuration (do not process modules)

```javascript

{

  module: {

    loaders: [

      {

        test: /^(?!.*(bower_components|node_modules))+.+\.js$/,

        loader: 'traceur'

      }

    ],

    noParse: [

      new RegExp(TRACEUR_RUNTIME)

    ]

  }

}

// With parameters

{

  module: {

    loaders: [

      {

        test: /^(?!.*(bower_components|node_modules))+.+\.js$/,

        loader: 'traceur?experimental&runtime'

      }

    ],

    noParse: [

      new RegExp(TRACEUR_RUNTIME)

    ]

  }

}

```

{

  // Modules set to CommonJS (consistent with Node.js and Webpack)

  modules: 'commonjs',

  // Source maps are built and fed to Webpack (use Webpack options)

  sourceMaps: true,

  // Traceur runtime by default not auto included

  runtime: false

}

```
