Add TypeScript support

[opensas]

Now that official TypeScript support for Svelte has been announced, It would be very convenient to also add it to the Repl.

The Repl has become a very useful tool, not only to showcase applications and share code snippets, but also to report issues.

This is not a simple change, with the way things are setup. But I have been looking into this and other improvements over the past week.

Great to know, it really is a very useful tool.

This would be a great addition

Indeed, this is one of the most interesting and anticipated REPL features.

Will this be considered by the core team? Would be pretty rad 😸

[vinayakkulkarni]

Is there any way we, the community, can help contribute in building the REPL using TS ?

[hperrin]

Is there a way to at least strip type declarations from a Svelte file, then we could use that?

Wold be nice for sure! Would make REPL useful again!

It is definitely not useless, but TypeScript support would be great!

omg, just found out, that ts in repl is not working. coming from angular, that hurts.
you are cutting off many devs trying out svelte via learning on repl.

Any update on this ?
It's still awaited feature.
