This sounds really great. As a Go developer I'm also really looking forward to their Go port of the filesystem watcher package — I agree that the existing packages don't fully allow to do a reliable recursive directory watch and it would be great to have something where you don't rely on C dependencies just for this thing.

> TypeScript 7.0 is often about 10 times faster than TypeScript 6.0 amazing

They've had a preview version of this available as ts-go for a while now, and I've been really happy using it on my projects. I just installed it and changed "tsc" to "tsgo" in a couple places and it just worked. I don't remember exact numbers, but I think an approximately 10x speed up is a reasonable estimate for my build times. They went from noticable-but-not-bad to imperceptibly-fast.

I'm looking forward to this. But it does amaze me how Microsoft with all it's power takes years to complete the port to a different language and bun does it in 7 days. Crazy times

Been using tsgo for months and unfortunately had many random crashes, the speedup made it worth it though. Looking forward to try the release candidate.
