Is Svelte 3 production ready?

I've been meaning to start a project with Svelte 3, but I'm not sure what tools to use. Is Sapper ready for v3 or is it still mostly on v2?

I've also somewhat been hoping that Svelte 3 will get TypeScript support so I can have a typed interface between my Svelte frontend and my Rust backend...

Svelte has been production ready for a while now (I've had it in production for 2+ years).

Svelte 3 was released 2 months ago, but TypeScript support is still in the works: https://github.com/sveltejs/svelte/issues/1639#issuecomment-...

On what I've read, Sapper is still v2. Understandable I guess since Svelte has a small community.

You can use Sapper with v3 already and could for a while now. It's RC for now though.
