'How to log every http.request made in Node

I want log every http request being made by a particular node app, and all of its modules. Wrapping requests in a function could work for all non-module code, the disadvantage would obviously be it doesn't include module code, and be cumbersome to do.

This is for apps already in production, only other option I thought of was tcpdump.

node.js

Setting NODE_DEBUG=http will make node log out detailed HTTP request information to the console.

Examples:

NODE_DEBUG=http node index.js

NODE_DEBUG=http npm start

For more information see:

List of the default available NODE_DEBUG attributes:

  • timer
  • http
  • net
  • fs
  • cluster
  • tls
  • stream
  • child_process
  • module

The easiest / least intrusive way is with a web proxy. Either an off the shelf one or one you write yourself in node. The machines the apps live on would have to get configured* to send all outbound traffic through the proxy and then the proxy can log the traffic. Details on implementation will vary based on which proxy/ approach you pick.

*Arguably, there are ways to do this such that the machines don't even know they're being proxied, but I've found in practice that's really hard to get right, especially with https traffic
