[Question] How does ping/pong work?

[Zammy]

Hello,

I am trying to build a simple RPC client on top of ws. I was implementing some kind of keep-alive but I do not understand how the ping/pong methods on websocket work. When I do ping I do not receive anything in the browser.

Also, is ws supposed to be used in the browser somehow?

ping/pong methods send frames that act as ping or pong messages as described by the WebSocket spec. Most browsers will respond to a ping with a pong automatically, but won't expose to the JavaScript object the fact that a ping or pong has been received, nor does it allow the JavaScript WebSocket object to initiate a ping or pong frame.
