I’m researching methods for real-time duplex server-to-server communication between Render Web Service (that would act as server) and multiple clients.
Since Render supports external communication only via HTTPS, I think I’m having following options:
- Websockets
- Websockets via Socket#io
- Server-sent events
- WebTransport
I’m most interested in WebTransport.
Docs say it operates on HTTP/3 and apparently Render supports HTTP/3 but this transport isn’t mentioned anywhere on Render docs or forum.
There is a demo for Node.js here that I could try to deploy: webtransport-nodejs
but was thinking that it’s faster to just ask and such information may be useful for other users.
BTW: Render community doesn’t allow me to include links in the post
