Microsoft Releases TypeScript 7.0 with a Native Go Compiler, Delivering 10x Faster Builds
↗
For developers, this drastically reduces CI type-checking and local build times, with major codebases like VS Code seeing full builds drop from over two minutes to under eleven seconds. However, the lack of a stable programmatic API in this initial release means ecosystem tools like webpack loaders and typescript-eslint cannot integrate yet, requiring some teams to delay adoption until version 7.1.

The native Go compiler provides significant speed improvements, reducing full builds in tested codebases by roughly 8x to 12x and cutting error-highlighting latency in editors from seconds to milliseconds.
Version 7.0 does not include a stable programmatic API, temporarily blocking integration by tools such as webpack loaders, typescript-eslint, and various framework tooling.
Microsoft offers a compatibility package, @typescript/typescript6, and advises migrating to TypeScript 6.0 first, as 7.0 converts previous deprecations into hard errors and changes default settings.
