Why are Socket.IO requests not showing up in the Network tab of Chrome Developer Tools?

Question

Google Chrome

Good evening. It is necessary to trace WebSocket requests on the page, but only 2probe is displayed in Network -> WS
: But, (only) incoming requests can be traced through , or through Network -> XHR But this format is inconvenient for me, besides, I also need to see outgoing requests . Yes, on other sites with Socket.io Network -> WS works perfectly (for example on https://socket.io)localStorage.debug='socket.io-client:socket'

Answer 1

Because seket.io itself chooses the connection method depending on the capabilities. Switch the filter to all and see what exactly the request is sent to.

Answer 2

If you make the first outgoing request immediately at the time of page load (read, at the moment of connecting to the socket server), then it goes by the ws connection. Where exactly are you looking for in the list of all requests to the server.
If you need to see it directly in ws, send it with a delay after the connection.
