The errors are because Babel now treats named imports with type: "json" as early syntax error (same problem in #5371). I don't know how we should fix this (ideally tighten our own parser), but that should be in a separate PR before this gets merged.

[bradzacher]

why did bumping the docusaurus version break the ast-spec tests?
shouldn't the version ranges be independent?

for the lint errors - you should be able to convert the "bad" cases to not use prettier by adding a template tag:

code: 'test',
// becomes
code: noFormat`test`,

[Josh-Cena]

shouldn't the version ranges be independent?

It's because Docusaurus depends on the newest version of Babel and it gets deduplicated.

Didn't see the lint errors, will fix those

[bradzacher]

Does docusaurus have a peer dep on babel?
Can we pin our local version of babel so that we can upgrade them independently?

[Josh-Cena]

No—it's a hard dep. This can wait a bit so we can fix the parser first.

[Josh-Cena]

About the Babel alignment issue, this is being asked here: tc39/proposal-json-modules#27 maybe it will eventually be a non-problem.

[bradzacher]

To make this all easier to manage - we'll merge #5491 first so that we have the autoformatting merged and we can update all other PRs at our own pace, then we can review the docusaurus changes in isolation and merge without trying to keep this PR up-to-date with main.

[bradzacher]

to fix the test failure - you should just move the test folder into the folder called _error_.

then i reckon this is good to go?

[Josh-Cena]

Might want to make it a separate PR, but anyway, here it is.

[bradzacher]

sorry - I probably should have mentioned you'll need to re-run the test to update the fixtures:

$ cd packages/ast-spec
$ yarn jest tests/fixtures.test.ts -u
