How to configure webpack to NOT recompile angular every time?

Question

I recently started working on a simple HTML5 + angular2 canvas game for routing, displaying highscores, etc. Since I do not touch the core of angular2, I would like NOT to recompile everything and merge everything together into one large file. Much more I would prefer to have angular2 core + http + router, and my application is in separate files.

Now I get almost 5 MB-package and even more .map, which pause my computer for a while when loading in the browser (the mouse gets stuck, the music stops playing for an instant, half), which is very annoying (I think this is due to the size of the package). Can I use multiple entry points to get this working?

Here is my webpack configurator:

module.exports = {
  devtool: 'source-map',
  entry: './src/app/bootstrap',
  output: {
    path: __dirname + '/dist', publicPath: 'dist/', filename: 'bundle.js'
  },
  resolve: {
    extensions: ['', '.js', '.ts']
  },
  module: {
    loaders: [
      {
        test: /\.ts/, loaders: ['ts-loader'], exclude: /node_modules/
      }
    ]
  }
};
