Ask HN: Why am I not able to see how WhatsApp web app is communicating with?

Hi,

I am trying to see what AJAX calls its trying to make, cant see a thing in the networks tab of Chrome brower.

Can please someone explain, what's this magic!

(Are they communicating using websockets?)

Hard to say from here. You can try going a level lower, run something like "tcpdump" on your machine and just watch what's going on. Might provide you some insight into the inner workings.
