Quite a while ago, I forced myself into using async/await by rewriting the entire krpc-node library into this: https://github.com/lucaelin/krpc.js
I was able to get things running in the browser and implemented dynamic service generation as well, but I simply do not have enough spare time to get the quality of this repo up... non of the tests are working at the moment, and there are quite some bugs.. I would be really happy if someone could help me out on this!
Cheers!
