Alright, so, how long until the current Vite codebase is replaced by a vibe coded Rust port? I give it a month or two.

Huh? Vite is already powered by a huge Rust codebase now that the release of v8.0 is live. They spent years developing their own parser and tooling to make it all possible.

As mentioned, Vite is already Rust, plus the same developers (the subject of the news) have developed https://viteplus.dev/

Probably in a year or two. Look at bun, same will happen to vite.
