Real-time chat platform frameworks: SignalR, WebSockets, ???
As a project I want to task myself with to learn some new technologies, I want to develop a chat app a la Discord. I'm curious what technologies are out there that can allow clients to connect to the server and receive "events" for things like messages, etc. etc. I know of WebSockets, which are probably the most common - but I'm curious what other tools or frameworks I could utilize on the server side that can still be easily accessed by cross-platform (mobile, desktop) clients. I'm looking for backend-only systems if preferable as I will likely try to build the clients (once I get to that point) in something else entirely.
I would also like to maybe do a little bit of premature overengineering and build it so that it could easily scale beyond just running it on one random computer for the entire world. I'm trying to be realistic and knowing that this is just a pet project I don't plan on trying to release it in a state to scale or compete with huge platforms, but I'd like to learn as maybe it could be something I could add to my portfolio. I have a feeling if I design it for small-scale, that upscaling it down the line will be a huge pain.
