Updating to RC.

Announced here: https://devblogs.microsoft.com/typescript/announcing-typescript-4-5-rc/

The biggest change was the removal of the ESM support for Node12. This generally doesn't impact us, since we have our own resolution. It seems like the additional extensions (e.g. .mts) are still present. I will add the changes here to support those (already being supported in deno_graph) in a follow-up commit to this branch.

Updated to the released version. Want to create some tests for the new features that overlap with swc as well to make sure everything works fine as well as "enable" the other file types that are being introduced (e.g. .mts).

@kitsonk any chance we could land this PR this week? It blocks me in #12866

It is blocked by the swc upgrade (@dsherret)

@dsherret I think the tests will pass, but there is a bit of a catch-22 with dprint, in that dprint panics on the private field detection, which it is trying to do the ast parse, but can't see the // deno-fmt-ignore pragma to skip it, because it panics when parsing.

[dsherret]

@kitsonk update the version of the typescript plugin in .dprint.json. I just forgot to update it in my PR.

[kitsonk]

@dsherret now dlint is updated as well, and there were some changes for the normal pass, but it seems now with the prefer-primordials pass, it is not only running that rule but every other rule as well, which it shouldn't (as well as ignoring the deno-ignore directives.

LGTM

[bartlomieju]

It seems cli/dts/lib.es2021.intl.d.ts was added in this PR, shouldn't STATIC_ASSETS in cli/tsc.rs be updated?

[dsherret]

LGTM :D

[kitsonk]

There is a test for import { type A } from "a.ts" as well as tests checking the new media types. Testing import assertions will be done under the import assertion features.

It seems cli/dts/lib.es2021.intl.d.ts was added in this PR, shouldn't STATIC_ASSETS in cli/tsc.rs be updated?

No, only assets which are not included by default do not go there, as per the comment:

/// Contains static assets that are not preloaded in the compiler snapshot.

And lib.es2021.intl is included in the snapshot.
