How do I debug Node js applications

Question

How do I debug a Node.js server application?

Right now I'm mostly using alert debugging with print statements like this:

sys.puts(sys.inspect(someVariable));

There must be a better way to debug. I know that Google Chrome has a command-line debugger. Is this debugger available for Node.js as well?

Hello @kartik,

Use node-inspector  from any browser supporting WebSocket. Breakpoints, profiler, livecoding, etc.

Install it with:

npm install -g node-inspector

Then run:

node-debug app.js

Hope it helps!!

Thank You!!
