In case you missed it, TypeScript 7 is a complete 10x faster version of the compiler & language server. It's a full port to parallelized native code.
It runs faster, uses less memory, and is more stable than ever before. xitter.twitterapi.xyz/typescript/status/1899…
Today we're thrilled to announce our effort to port the TypeScript compiler and language service to native code, gaining a 10x speed boost in build times and editor responsiveness!

📣 TypeScript 7's Release Candidate is now out! 📣
The new native port is almost here. Try it out on your codebases, and make sure your team is ready for the upcoming 7.0 release!

Something subtle from some recent VS @code release notes: VS Code core, and all its built-in extensions, are now type-checked with TypeScript 7 native previews!

ALT From the VS Code 1.119 blog post: Typechecking now uses TypeScript 7 for faster development iteration Last iteration we moved VS Code's main watch task to use TypeScript 7. This iteration, we finished the migration to use TypeScript 7 for all built-in extensions and core code. By migrating the Copilot extension to use TypeScript 7, we cut the typechecking time from 22 seconds to 4 seconds. These dramatic speedups enable both developers and agents to iterate more quickly in the VS Code codebase.
You can try it out on your project by installing our native-preview package from npm.
New releases are published daily, and are already used by many teams in production!
