I tried implementing my own using several examples I have found online. It *kind of* works. It seems like I get blocked while trying to receive data back in the recv() loop. I never reach the end. I'm not an expert in sockets/networking, but maybe I'm not wrong in guessing it is because of the non-blocking nature of Node.js ?

Do you need to use non-blocking sockets here? I think, from a quick
skim of your code, that you'd do better with a blocking socket. Tip:
Any time you have a sleep(1) call in your code, look to see if it's
doing the wrong thing. In this case, I'm pretty sure it is. Sleeping
for a second and then trying to read from a nonblocking socket seems
like a messy way to just read until you have what you want.

There's another thread happening at the moment about networking in
Python. You may find it of interest.
