Here are my recently learnt tips for advanced usage of the wonderful Webpack

1. --hot does not do would you would expect. webpack --watch and webpack-dev-server do what you'd expect --hot to do, even without that option.
2. --lazy stops WDS from doing what you'd expect --hot to do.
3. --hot allows modules (files) to be updated in place, without reloading the webpage.
4. --open is pretty handy
5. --inline can be moved to webpack.config.js
6. Webpack has built in support for lazy loading through the AMD spec for require(): require.ensure()
7. Support for multiple bundles (entry points) is beautiful
8. WDS serves up static files if you keep them in the context path, with no additional config

What I have not answered yet, is what the the advantage of stylesheet bundles is, if the styles are cached in the browser along with the JavaScript bundle?
