Changes to node_modules should trigger recompilation

1. Add import 'react-router' to index.js
2. See module not found error
3. npm install react-router
4. Still see module not found error
5. Press “save” in index.js
6. Now it compiled successfully!

Steps 4 and 5 should not be there. We should find a way to tell webpack that node_modules have changed, and it’s worth trying to recompile.

Ideally we should not have situations where user is forced to stop the bundler and run npm start again. I remember having such issues when switching branches. Hopefully fixing the above use case should be enough, but if you’re familiar with other cases where a restart is required, please write in this thread.

What about using this? https://github.com/ericclemmons/npm-install-webpack-plugin I think that solves our problem.

I have a vague recollection that this used to “just work” with npm2, but that it stopped working after I upgraded to npm3.

Didn’t have a chance to look into that, though.
