As someone who likes to play around with node.js for side projects, and without an IDE for developing the applications, it’s quite important for me to have some sort of debugging tool so that I can understand and analyze problems with my code and solve them. node-inspector is quite a good utility to have as a debugger for node.js.
The installation steps are simple, the UI resembles Chrome Developer Tools, Firebug etc. What more can one ask for?!
