Rust Port of TypeScript (Tsc)
ts-rust (aka tsc-rs) I wanted to see if LLMs could port the TypeScript compiler, checker and lsp to Rust. It cost over $420,000 in tokens to do it, but you could probably have done it for ~$20k (see below) Motivations Test model capabilities Make a fast TypeScript type checker Make a ts checker that can work in WASM with high performance Memes Warnings This is an early release. It has 100% compatibility in every real world project we have tested.

It has 100% compatibility in every real world project we have tested. It should work as a drop in replacement for the vast majority of apps. See Known problems. Also worth mentioning: I've never read a line of this code. Install Be warned, I have no idea if this will actually work.
