A dead simple way to import/require your RAML definition files and get back a JavaScript Client Class for that definition with Webpack.

npm install raml-client-loader --save-dev

module: {
    loaders: [
        {
            test: /\.raml$/,
            loader: 'raml-client-loader'
        }
    ]
}

var Client = require('./path/to/definition.raml'),
    client = new Cient();
    
client.users.userId(1).get();
