We Improved Reliability of Our WebSocket Connections

Ah, yep, that explains it.

They do solve this problem as documented: https://github.com/socketio/engine.io/blob/64d57545116c7a7d9...

• socket.io-client

  4 10,536 6.5 TypeScript

  Realtime application framework (client)

  

> Conversely, if the client does not receive a PING packet within `pingInterval + pingTimeout`, it will consider that the connection is closed.

Indeed looks like a solid way to solve the client-side recognition of a broken connection!

That said, I'm a little confused because I cannot find any mention of `pingTimeout` in their JS client [0], and `pingInterval` is only mentioned in an implementation of a test server [1]. I wonder if I'm looking at the wrong thing.

I do wish we didn't all have to reinvent this wheel though…
