How to Install / Upgrade: Microsoft Releases TypeScript 7.0 with a Native Go Compiler, Delivering 10x Faster Builds

Microsoft has released TypeScript 7.0 with a native Go compiler that improves build speeds by 8x to 12x, with those gains shown on real codebases. The release is aimed at faster typechecking and builds while TypeScript stays an open-source project.

To install or upgrade, move your project to TypeScript 7.0 and bring in the compatibility package so existing tooling can keep working during the transition. Update your TypeScript dependency to 7.0, install the compatibility package your tooling needs, then reinstall dependencies and re-run your usual build and typecheck commands so the native compiler is in use.

The main gotcha is that TypeScript 7.0 does not yet have a stable programmatic API; that is expected in 7.1, so tools that depend on the programmatic API may need the compatibility package or a later upgrade. Verify by confirming TypeScript 7.0 is installed, that your build completes with the new compiler, and that you see the expected faster builds relative to your prior setup.
