The compiler commands now use
tsrsfor type checks, consumer fixture compilation, and cleanup. This removes duplicate type checks and the directtypescriptand@typescript/native-previewdependencies.scripts/tsrs.jsselects native binaries on Apple Silicon and Linuxx64orarm64. It uses@ts-rs/wasmon other platforms, including Windows and Intel macOS.The performance measurements use Apple M4 Max, macOS
26.2(arm64), and Node.js24.22.0. Each command ran 50 times after five warmup runs. The runs used random order, fresh processes, warm filesystem caches, and the same project configuration withincremental: false. Timings include shell and compiler startup and excludevpstartup.The baselines use
typescript@7.0.2and@typescript/native-preview@7.0.0-dev.20260421.2. Bothtsrspackages use0.15.0-ts7.1.0-dev.20260929. These compiler versions target different TypeScript revisions.tsc --noEmittsgo --noEmittsc --noEmit && tsgo --noEmitnode scripts/tsrs.js --noEmit(native)node scripts/tsrs.js --noEmit(WebAssembly fallback)The native script takes 71.6% less time than the previous combined command, a 3.53× speedup. The WebAssembly measurement forces the fallback on the same Mac. That path is slower and provides support for platforms without native binaries.
