The rust version is being used by Claude Code though - which is a fairly large product!

I was hoping for more push back against https://bun.com/blog/bun-in-rust - which is pretty thorough and has some decent arguments and reasoning for why they did the rewrite.

I think they meant “released and available for use” rather than just out in the wild.

It is available for use: `bun upgrade --canary`

it doesn't imply that lot legacy apps won't crash in prod when it will be actually released. Cool that some complex app is working but is nothing proving that everything will be fine when everyone will try to upgrade.

How much of the Bun/Node API surface does Claude Code actually use though? Conceptually it's a relatively simple TUI application.

Yeah, but it's a TUI that has more bugs and worse performance than any other TUI in history. It's not like we'd notice a user after free.

I agree and I think the ideas in Elm are applicable in many other contexts. Adopting a new language is just hard, especially with larger teams. I ended up taking some of the ideas of Elm but implementing with Rust and TS - https://dave.tonge.org/articles/make-ts-boring/

The basic idea - all application state and view model creation is in Rust (compiled to Wasm). I'm using Rust not really for performance, but for its strong type system. Components are in TS but have a strict contract they can only accept plain input props and output events. Rust processes the events and ships a view model patch to TS.

This is not "Elm in Rust/TS" but it is definitely Elm inspired.

Thanks - I missed that. From the previous discussion here is one of the recent videos: https://vimeo.com/1053667887

Longtime HN lurker, I know this team and it is a genuinely useful tool. Congrats on the HN launch.
