Hi HN,<p>I'm working on an Erlang inspired WebAssembly runtime for the backend[0]. Recently I added TCP support and was looking for apps I could build with it. I ended up building a telnet line chat app. It was a great dogfooding experience and has a nice retro feel to it.<p>You can access the US server with<p>> telnet lunatic.chat<p>or the EU one with:<p>> telnet eu.lunatic.chat<p>You should pick the one closer to you as all the rendering is done on the backend and lower latency will mean better UX.<p>The server is open source[1] and written in Rust. The Rust code is then compiled to WebAssembly and runs on top of Lunatic. Each connection runs in a separate (lightweight) process, has it's own state and sends just a diff of esc-sequences back to the terminal to bring it up to date with the current render buffer. Everything is deployed to an ARM Linux box.<p>[0]: https://github.com/lunatic-solutions/lunatic<p>[1]: https://github.com/lunatic-solutions/chat
