HMR doesn't work for npm linked modules

[ramivalta]

Hot module replacement doesn't seem to be working when using npm link. Webpack correctly notices there are changed files and rebuilds the bundle, and browser console shows what files have changed and seemingly updates the correct modules, but the browser doesn't get the updated code until the app is restarted (with rs).

Example:

> ls -l node_modules/linked-module
lrwxr-xr-x  1 rtv  staff  55 Feb  2 12:29 node_modules/linked-module -> /usr/local/lib/node_modules/linked-module

Edits file called WantContainer.js in linked-module

webpack: bundle is now INVALID.

Yet the browser doesn't get the updated code.

Hello @TiiL this is a known webpack issue with symlinked directories, it will be fixed in version 2 👍

[ramivalta]

Thanks @iam4x, time to upgrade I guess.

@iam4x Version 2 of webpack? Any details on what this fix is?
