Is there any framework like bottle for Node.js

i am a python-er before, now, i found node can give me more motivation. but express is too complex for router than bottle. what's best choice of router framework for node ?

I would take a look at koajs. It's a simpler, smaller framework with a killer feature: JavaScript Generators. Which means you don't have to use callbacks.
