I found these great resources to get me going with node.
Totally new to it? Take a look at this video from the creator of node himself.
If you are unafraid and want a bit more lenghtly tutorial, in which you actually create something following best practices, you should check out nodebeginner.org. I was able to compare a lot of the instructions with my own way of working in .net.
Hands on node.js is an ebook with accompanying exercises, great for a more traditional way of learning. The first part of the book is free and the full version will only set you back a few dollars.
Finally there’s another Manning book under way, you can already grab the MEAP.
There’s plenty more out there but I found these to be the most helpful for me.
