Announcing TypeScript 7.0

Today we are proud to announce the availability of TypeScript 7, a 10x faster native port of TypeScript!

Since its early days, TypeScript has promised to deliver on JavaScript that scales. By bringing strong type-checking and rich tooling to the world of JavaScript, TypeScript made it possible to build non-trivial high-quality apps across platforms.

Last year, our team unveiled TypeScript’s next step in scaling: making every part of the toolset an order of magnitude faster. The mission was a native port of TypeScript built in Go that could make the most of modern hardware. This port was done as faithfully as possible, writing new code while maintaining the structure and logic of the original codebase to keep results consistent and compatible between the two compilers. The key difference is that with this new codebase, TypeScript 7 brings native code speed, shared memory multithreading, and a number of new optimizations that typically yield speedups between 8x and 12x on full builds.

Just as with any other release, TypeScript 7 is available via npm:

npm install -D typescript

That will get you the new tsc executable in your workspace (which you can run via npx tsc). Of course, a big part of the TypeScript experience is also about editor support. Your favorite code editor should easily support TypeScript 7 with its new support for the language server protocol (LSP), and its new speed and multithreading improvements. Whether you’re using something like VS Code, Visual Studio, WebStorm, or any other modern editor, TypeScript 7 should work great. Just check your editor’s documentation – for example, VS Code has a dedicated extension for TypeScript 7 that you can use today, and Visual Studio will automatically enable TypeScript 7 based on your workspace.
