how to monitor the network on node.js similar to chrome/firefox developer tools?

Question

When developing client side javascript applications, the developer network panel is invaluable for debugging network issues:

Answer 1

Use external HTTP Debugging tool. Your options include:

• node-http-proxy as seen in How do I use node.js http-proxy for logging HTTP traffic in a computer?
• middlefiddle written in node.js (but abandoned for 3 years now) https://github.com/mdp/middlefiddle
• mitmproxy - a CLI tool http://mitmproxy.org
• fiddler http://www.telerik.com/fiddler
• and many more - https://www.google.pl/search?q=HTTP+debugger

You fire up one of those, tell them where to route the traffic, and point your application at that debugging proxy instead of the real server.
