skate VS chat

Depending on your use case, you could use something similar to skate (written in go but the approach should still work). It's public key based so that the first time you use it it creates a new account, then if you use the same key again it uses the same account. You can link multiple computers by authorising the new machine/key from the original account.

These apps look wonderful, only taking a casual glance at the repo, has anyone used, or would one recommend using Skate (https://github.com/charmbracelet/skate) as a personal PW manager or even keychain?

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.

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.

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:

Recently I implemented a command line chat server in Rust using an actor framework. I model each TCP connection as an actor.

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.
