Webpack: load js modules dynamically from a URL at runtime

I am currently working on a library which should dynamically load a JavaScript from a remote host and instantiate that.

I am writing the library in TypeScript and my plan is to use Webpack as a bundler.

On another host (remote system) runs a provider which should serve JavaScript code (see here: https://stubs.d-koppenhagen.de/stubs/SimpleStub.js). The library will dynamically resolve "Identitys" via Webfinger. These Identitys represented by an object and they having a property pointing to a "Stub Provider" which will serve JavaScript code (the link I mentioned before). My library should load this script during runtime (s the library don't know the target for this stubs before) and should use it.

currently my webpack.config.js looks like the following:

var path = require('path');
var webpack = require('webpack');
var WebpackBuildNotifierPlugin = require('webpack-build-notifier');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

const PATHS = {
  src: path.join(__dirname, './src'),
  build: path.join(__dirname, './dist')
};

module.exports = {

  entry: {
    wonder: PATHS.src + '/wonder'
  },
  output: {
    path: PATHS.build,
    filename: '[name].js',
    library: 'Wonder',
    libraryTarget: 'umd'
  },
  devtool: 'source-map',
  module: {
    loaders: [
      {
        test: /\.ts$/,
        loader: 'ts-loader'
      }
    ]
  },
  resolve: {
    extensions: ['.ts', '.js']
  },
  plugins: [
    new WebpackBuildNotifierPlugin()
  ]
};

And here is a part of the library code:

require.ensure([], function() {
  require(localMsgStubUrl);
});

When I am now including the bundled library in an example app, I will get the following error: Error: loading chunk failed

So is there a way to tell webpack not to bundle the code which is required from a external resource loaded from a URL so that I can use that code like it is?

I don't want to tell webpack the URL statically in a config as maybe other stubs I am loading are located on a different target.

Thanks in advance for your help!
