Creating websocket.Server from http2.createSecureServer

[cTn-dev]

Hi (sorry for creating the ticket here, stackoverflow didn't seem like the right place for this).

I was wondering if there is a way, or if it will be possible to create a websocket server on top/from the http2.createSecureServer instance.

Right now i have to create an additional regular https.server and then create the websocket server from this instance, this works fine but it forces me to have another port open (which makes sense).

I am aware that http2 in node is still in "experimental" stage, but better support for it in ws would be great.

There is no support for WebSocket over HTTP/2. See https://daniel.haxx.se/blog/2016/06/15/no-websockets-over-http2/, nodejs/node#15230.

if anyone else stumbles on this tix.
HTTP2 web-sockets are now reality - added as part of this rfc: https://datatracker.ietf.org/doc/html/rfc8441

Firefox is defaulting to websockets over http2 (if the server advertises support) - see network.http.spdy.websockets
Chrome also allegedly added support to http2 web-sockets recently:

Reverse proxy solutions are beginning to support http2 web-sockets as well:

There are significant changes in how ugrade happens over http2 - notably there are no Upgrade header utilized, instead extended HTTP CONNECT method is being used to bootstrap websocket protocol.
