Thanks for maintaining this fork - it's very useful.

Could you merge the following PR from upstream? It's a simple change to enable websocket proxying support in development. facebook#1090

Hi @smulas Thanks for the quick turnaround. One issue though, I'm getting this error installing 0.2.7 on windows:

Looks like a dependency missing: hoek - any ideas? I've tried removing and reinstalling, but same error.

Hi @joewood, found the error, i think the problem is in the relase script.
i released just now the version 0.2.9 (without using that script) and should work on windows as well.

Yes, thanks - that fixed it !
