I have two friends who both profession engineers that, like me, have been writing Rails code for the last 5+ years and are both quite proficient and passionate about Rails. Recently both started looking at and playing with http://www.phoenixframework.org/ - have you all seen this? Its claims are quite interesting to me with regard to performance - especially as I begin to use rails as more of just a backend system/api for clients.
There are always tradeoffs with any system / framework, and certainly the biggest one I see right now is that Phoenix lacks maturity and ecosystem of Rails. The gems that are available and community support (thanks @justin!) for Rails is amazing - but like Phoenix, Rails had to start somewhere.
So, if you check out Phoenix, I’d love to hear your thoughts, concerns, and/or dreams about it. I have yet to do any serious tire kicking there, but since the name keeps coming up, I thought I’d ask a group of other passionate rubists their thoughts. Thanks all!
