How to debug node js app with breakpoints and everything?

I've installed node-inspector just to find out that it doesn't support breakpoints :| What's the point in it at all, bearing in mind that on big part node code is asynchronous and you simply cannot follow it step by step?..

I'm definitely missing a point here...

Anyway to debug node code with breakpoints and everything?

yupp, I've successfully used node-inspector. If you want permanent breakpoints, simply insert debugger; in your code. See http://nodejs.org/api/debugger.html.

Making node wait until a debugger is attached, using node --debug-brk script.js , can also be very helpful.

I think You can get your answers from this Link

And one more thing is you can push dynamic changes to V8 Debugger too.

Just to elaborate a bit here:

Set a debugger wherever you want the breakpoints to be and then run your code with node debug script.js/index.js

When the debugger stops at you breakpoint, you will need to repl to inspect the variables.
