Bundle size becomes much bigger with Webpack 2

When running my build on the stable branch i get this

Hash: bcb00f2d62e74000ed17
Version: webpack 1.13.0
Time: 4193ms
              Asset     Size  Chunks             Chunk Names
    index.bundle.js  2.26 MB       0  [emitted]  main
index.bundle.js.map  2.55 MB       0  [emitted]  main
    + 356 hidden modules

but when i upgrade to the latest beta the bundled file size and the number of modules becomes much more

Hash: 7fcf40a3eb38c81d3e15
Version: webpack 2.1.0-beta.7
Time: 4562ms
          Asset    Size  Chunks             Chunk Names
index.bundle.js  6.9 MB       0  [emitted]  main
    + 465 hidden modules

The bundled application is here angular2-esnext-todomvc.

  1. @vpachedzhi The only explanation I can think of is that source maps are getting inlined in your webpack 2 setup. Could it be that -d flag that enables the behavior? You could try setting devtool: 'source-map' explicitly in your configuration to generate the separate source map files.
