tsc performance consuming .ts vs .d.ts files in npm packages
Recent Gists from andrewbranch
tsc-ts-vs-dts.md Original Tweettsc performance consuming .ts vs .d.ts files in npm packagesWhat if TypeScript libraries published just .ts sources to npm instead of .js and .d.ts files? This might already be tempting for Bun-only libraries, but how will that impact users? This is easy to answer by experimenting on existing libraries that ship .js, .d.ts, and .ts files.RxJS ships .js and .d.ts files, but also .ts files for debugability purposes. By tweaking its package.json "exports", we can compare tsc performance on this file with imports resolving to .d.ts files vs .ts source files:import {} from "rxjs";import {} from "rxjs/ajax";import {} from "rxjs/fetch";import {} from "rxjs/operators";import {} from "rxjs/testing";import {} from "rxjs/webSocket";Results.d.ts.tsFiles268317LOC49k62kInstantiations ❗11k46kMemory92 kB118 kBParse time.76 s.91 sCheck time ❗1.48 s3.02 sTotal time ❗2.58 s4.43 sObviously .ts files look really bad here, which is what I was expecting.
