Motivating Question

tsc tends to be the bottleneck in modern TS toolchains. Native compilers like esbuild and swc are amazing, but they don’t perform type-checking, so you still need tsc as part of your build process. Would it be possible to speed up tsc by opaquely compiling it from a JIT’ed JavaScript program into some more optimal format like WASM or native?
 

Notes

  • This may not be worth the effort, but seeing as how quickly native compilers gained adoption within the TS ecosystem, a similar solution for replacing the type-checking and generation portions of tsc would have huge implications.
