perf: use tsgo for typechecking in build and vitest#136
Merged
Conversation
Swap tsc -> tsgo (@typescript/native-preview) for the --noEmit typecheck step in all package build scripts and as vitest's typecheck.checker. ~45% faster typecheck and ~27% faster full build per package; vitest typecheck phase ~210ms -> ~70ms. All test suites still pass and the checker still reports type errors. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The tsc->tsgo build swap left knip flagging tsgo as an unlisted binary (it resolves from the root @typescript/native-preview dep, not per-package), failing pnpm lint. Ignore tsgo in each package's knip.json, matching how tsdown/vitest/knip/oxlint are handled; drop the now-stale tsc ignore in core/coda.
