Eran Hammer on Node.js web framework design tradeoffs and why there is no “best” framework:
If you haven’t read Netflix’s Node.js in Flames blog post you should. It is a great deep dive into debugging a node performance problem. The post includes useful tips that can help you solve similar problems.
That said…
My feedback from the perspective of a framework developer is quite different. I found the tone and attitude towards express.js to be concerning and somewhat offensive. Here was a developer blaming the framework he chose for poor architecture when they never bothered to actually learn how the framework works in the first place.
Recommended for understanding why Express works the way it does, what other frameworks do differently, and why none are superior to the other without considering your own requirements.
