Charm – tools to make the command line glamorous
TUIs over ssh/telnet can be a lot of fun. Especially in cases where multiple people can interact with each other on the server. It simplifies the programming model as you only have one state on the backend that you render to multiple connections. Syncing up everyone becomes trivial. You can also use some React concepts, like rendering a virtual TUI and sending just the right set of minimal escape sequences back to the user to bring their display up to date.
A few months ago I implemented a telnet chat server[0] for fun and it was surprisingly easy to do so. Even by using a wasm vm that I was still working on at the same time.

Launch HN: Lunatic (YC W21) – An Erlang Inspired WebAssembly Platform
We are investing a lot of effort into making Lunatic feel native to the particular language and ecosystem. If you look at the Rust chat server we built in Lunatic (https://github.com/lunatic-solutions/chat), it fully integrates with cargo. You just run your typical “cargo run” command, it will compile the app to wasm and use lunatic to run it. If you want to run your test, you can just do “cargo test”.
wasm-bindgen is necessary only because it’s really hard right now to merge the wasm world and the JS one in the browser. We have the advantage here of staying out of the browser.

How I built a telnet chat server in 2021 with WebAssembly
It took me around a week to build it with Rust + Lunatic and you can check out the code here. If you would like to try it out you can connect to it with:

The Stakker actor runtime: Beyond "Go++"
Recently I implemented a command line chat server in Rust using an actor framework. I model each TCP connection as an actor.

I built a telnet chat server with WebAssembly
Hi HN,
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.
You can access the US server with:
> telnet lunatic.chat
or the EU one with:
> telnet eu.lunatic.chat
Pick the one closer to you, as all the rendering is done on the backend and lower latency will mean better UX.
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.

What would you rewrite in Rust?
I believe that https://github.com/lunatic-solutions/submillisecond wants to be that.

From Erlang to Rust and Lunatic
Lunatic is exciting, I'm keeping an eye especially on the submillisecond web framework that targets wasm: https://github.com/lunatic-solutions/submillisecond

Is Rust Ready for the Web Yet?
Lunatic runtime for Rust to avoid the async parts might become quite nice in the future: https://github.com/lunatic-solutions/submillisecond
Not sure what it might take for someone to write database connectors for it but it does look promising.

Htmx, WebAssembly, Rust, ServiceWorker Proof of Concept
What a coincidence, I was just discussing on discord a similar approach for our Rust web framework submillisecond[0].
Submillisecond uses lunatic to run Rust code compiled to WebAssembly on the backend. We are working on a LiveView-like library now. And one thing I would love to give developers for free is an offline-first experience. You write everything in Rust, compile it to WebAssembly, run it as a regular backend on lunatic, but also allow for moving the whole server into the browser for a offline experience. If SQLite is used for the DB, it could also potentially run in the browser.
This doesn't need to move the whole app into the browser, but could do so just for more latency sensitive workloads that don't fit LiveView well. Like form validation on every keypress, etc.

Lunatic: Erlang-Inspired Runtime for WebAssembly
Web socket support was added a few days ago[0], but it's still not part of a release. I will probably push out alpha1 tomorrow including it and a few other changes.
