How to Sniff signalR calls using chrome Developer Tools
I downloaded Jabbar chat website and ran it inside Chrome. I wanted to see what all is happening between the browser and server and for that checked the network tab. However, I see no entry in network tab (neither xHr nor websocket or anything else) but SignalR is working fine. It does send and receive messages. I wonder what is signalR using that developer tools cannot log. Is there a setting required in developer tools?
Nowadays when your signalR is using WebSockets it is a bit different. Starting with Chrome 58 you have to click on the Network tab and then activate the WS filter. There will be one entry when the signalR connection has been established. Now click on the Frames sub-tab. Here you see every message which has been received by the browser:
