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's simple to get started
npm install -D typescript@7
Then run `npx tsc` as usual for a new native experience.

The 10x is real for many projects, and the speed improvements make a huge difference for teams at scale. TypeScript 7 drops time in CI, and minimizes delays in editors like VS & VS Code. That makes every part of the developer inner loop feel snappy.

The new codebase has been battle-tested by many teams (and entire companies) using it in production for over a year now. In fact, in the editor TypeScript 7 is *more* stable than TypeScript 6, with fewer crashes and lower memory usage.

TypeScript 7 has all the editor features you love, like auto-imports, find-all-references, expandable hovers, inlay hints, code lenses, linked editing, semantic highlighting, import sorting, and more.
They're just a lot faster now.

With TS 7, you'll still have broad editor support. IDEs like Visual Studio and Webstorm will easily support TypeScript 7.
For VS Code, we have an extension you can install today!

With this new version, TypeScript officially supports the language server protocol (LSP). So just pick your favorite editor and enjoy the speed improvements!

TypeScript 7 also ships a new `--watch` mode based on a Go port of Parcel's watcher. This brings more efficient and reliable file watching to TypeScript users across platforms.
If you tried earlier versions of TS7, you can expect way less CPU usage on idle with `--watch`.

Under both `--watch` and in the editor, TypeScript 7 also now periodically releases unused type-checking state after enough idle time. For bigger projects, this should help reduce memory usage after peaking.

TypeScript 7 also brings parallelism with new 🧪 experimental 🧪 flags to tweak it.
`--checkers` controls the number of type-checking workers, while `--builders` controls concurrent project builds.
Use more on powerful machines, or scale down to fewer to control memory usage.

We know people will still need TS 6 for API usage.
That's why there's a new `@typescript/typescript6` package that provides
- the TypeScript 6 API
- a separate `tsc6` binary
Install it side-by-side with TypeScript 7, and don't worry about conflicts with `tsc`.

@typescript @drosenwasser when will this be available in TypeScript Enterprise Edition? The last CD ROM you gave me is on TypeScript 2.0…

@typescript 7 matters less than migration pain when monorepos hide old compiler flags

@typescript 10x faster?!! The TypeScript team COOKED! Congrats to the whole team for their dedication in rewriting the compiler. I still don't fully understand going with Go over Rust, but the results are still IMPRESSIVE 🚀🤘

@typescript @JamesMontemagno I think you guys need to make it more clear that this speeds up the compiler. Not runtime execution.

@typescript @emanueledpt I've tested 7, it's insanely good. Fast, efficient, and just really nice. Might want to check this out for Synara 👀

@typescript You should really start using perryts.com to compile Typescript to native binaries. :)

@typescript The migration to a Go compiler makes it work so much better.

@typescript I can't stop laughing 🤣 My entire feed is full of people saying that now their code (itself) will run 10x faster 😂
