You know that feeling when you've found exactly the tool you were looking for? And it's cheap too? Well I got that when I found WebStorm. It has precisely what I was looking for in a node.js IDE. Some of you (non existent) readers may say, "bah! IDE's are for teh noobz!" And who knows, maybe these phantom tech elitists are correct. Throughout college I used emacs and programmed in C++ and I liked it. But now I've been spoiled by Visual Studio and C# and I don't think I can ever go back.
So WebStorm has all the features I love about visual studio, but works well with Node.js, and on my mac. Code formatting, smart auto-complete, "jump to definition", easy to add JsDoc comments... I'm actually surprised I hadn't found it earlier, since most of the VS features I love are from a plugin called Resharper, which is made by the same company (JetBrains). And unlike VS, the price is pretty reasonable ($50).
