Replace typescript with @typescript/native-preview (tsgo) for type checking and declaration generation. tsgo is Microsoft's Go-based rewrite of the TypeScript compiler, promising up to 10x faster builds and significantly reduced memory usage.
⚠️ tsgo is still in preview and not production ready.
This is exploratory work to validate feasibility, surface required code changes, and track upstream progress toward a stable release. Upgrading to TypeScript 6.0 first may be a good bridge step, it's the last JS-based release and deprecates the features removed in 7.0, letting us fix compatibility issues incrementally before the full native switch.
Known blockers
- Some packages still need fixes to build cleanly under tsgo
- Declaration emit is not fully complete upstream (some types get dropped during exports)
--build mode (project references) still has gaps- Aligns with TS 5.9 semantics, some deprecated patterns may need migration
