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.inspe         


        

Answer 1

Node has its own built in GUI debugger as of version 6.3 (using Chrome's DevTools)

Simply pass the inspector flag and you'll be provided with a URL to the inspector:

node --inspect server.js

You can also break on the first line by passing --inspect-brk instead.
