I have a very simple setup with Webpack and Babel for a small library.

Before, I had the following architecture to generate a ES5 version of the library:

Webpack has changed a lot, now you can get the same results as the Felix Kling answer but with webpack config. You should add the libraryExport key in the output config and set it to "default". That would set your main class as the root content of your library. Here are the docs.

Your webpack config should be like this:

module.exports = {
  entry: {
    pentagine: "./lib/pentagine.js",
    demos: ["./demos/helicopter_game/PlayState.js"]
  },

  output: {
    path: __dirname,
    filename: "./build/[name].js",
    libraryTarget: 'umd',
    libraryExport: 'default' //<-- New line
  },

  module: {
    loaders: [
      {
        test: /.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/,
        query: {
          presets: ['es2015']
        }
      }
    ]
  }
};
