ts-r: A port of TypeScript to Rust
TypeScript tooling, rebuilt from scratch in Rust
Six TypeScript tools written from scratch in Rust. On excalidraw, ts-r-dev updates the page 8.6 ms after a save (Vite 8: 35 ms) using less than half the memory. Each tool reads your existing config, so you can swap in one at a time.
Hey PH 👋
I'm building ts-r: TypeScript tooling written from scratch in Rust. That means the lexer, parser, checker, bundler, linter, dev server and LSP, with no swc, esbuild or oxc underneath.
Each tool stands alone, so you don't have to migrate everything. Try `ts-r-dev` in place of Vite or `ts-r-run` in place of tsx, and keep the rest.
What we measured on public code:
- Dev server (excalidraw): a save shows up in the page in 8.6 ms (Vite 8: 35 ms). It starts in 538 ms (Vite: 1,032) and uses 153 MB (Vite: 364).
- Hot reload stays flat as the app grows: 4.9 ms at 1,000 modules, 5.4 ms at 50,000.
- Running a .ts file: 29 ms (tsx: 79 ms, Node's type stripping: 50 ms).
- Editor memory (RxJS, every file open): 377 MB (TypeScript 7's LSP: 820, tsserver: 1,091).
It's alpha, and the benchmarks page also shows where we lose. The bundler is about level with esbuild only with its cache on, and the type checker doesn't match tsc's diagnostics yet (77.6% of the top 1,000 npm packages match). Every number links to the command and commit that produced it.
