Theo - t3.gg(@theo):5 issues have been filed on tsc-rs so far. Of the 5, 4 of them are issues with the official upstream typescript version we ported. This port is so faithful that the vast majority of "issues" are just accurate recreations of real typescript behavior. Wild.

Announcing tsc-rs (aka ts-rust), my complete rewrite of the Typescript compiler, type checker, and LSP, all in Rust. This is a project I've had agents working on for 5 months now. I burned ~$400k of Codex tokens and got nowhere. Burned ~$20k of Opus and got there in 2 weeks. I have not read a single line of the code. tsc-rs is an open source drop-in replacement for tsc, and it's available now.
