Question

LearnBoost seems to have a new project called engine.io that in theory seems to be similar to socket.io. 1) Under what scenarios would you use one versus the other? 2) For new

"What's next

1.0 is right around the corner, which features our next-generation realtime core, Engine.IO. The 0.9 branch will only receive maintenance updates to ensure maximum stability. "
