These features will allow us to only use what we need in each crate.

These re-exports makes things a lot nicer because then we only have to depend on deno_ast and not a bunch of swc crates.

Discussed on a call with David, I"m in favor of this approach as well, it"s good to contain SWC to a single crate.

This was kind of annoying and necessary for deno_lint.

Would be good to maybe add a comment here with that example from deno_lint?

I"m going to add documentation comments everywhere in the second pass once everything looks ok and is integrated (so I don"t waste my time documenting stuff that will change). Right now the crate is super bare, but yes I"ll do that then.

Ignore my previous comments then! 😉

This is a very rough initial implementation. There is not much documentation and barely any tests (just the bare minimum to get going).
After we"ve agreed on the implementation I"ll spend some time adding tests and do the CI.
Downstream PRs:
I will integrate this later into dprint-plugin-typescript.
