feat: support TypeScript 5.1 #7088

JoshuaKGoldberg · 2023-06-06T05:11:17Z

Note: This doesn't Block You From Linting TypeScript 5.1

You can still use typescript@>=5.1 with @typescript-eslint/eslint-plugin & @typescript-eslint/parser. There are no breaking changes in TS 5.1 that would block you from linting existing code. JSX namespaces (<MyComponent a:b />) should generally be linted properly.

Until this PR is merged and a new set of typescript-eslint package versions are released, your console may see a log like WARNING: You are currently running a version of TypeScript which is not officially supported by @typescript-eslint/typescript-estree..

Status Update: June 26th 2023

Looks like TypeScript's latest releases have fixed the issue. We should be ready to release a new version with this PR's changes soon - pending review.

Status Update: June 9 2023

This PR is blocked on out-of-memory (OOM) errors running a set of important unit tests for the parser. The OOM error only occurs with TypeScript 5.1, not locally.

We're working on identifying which commit to TypeScript introduced the change that coincides with this OOM error being introduced. In #7091 we narrowed it down as follows:

✅ Running with typescript@5.1.0-dev.20230301 does not exhibit the OOM error
❌ Running with typescript@5.1.0-dev.20230302 does exhibit the OOM error

~~Our next step will be to write a script to run against individual TypeScript commits.~~

It looks like microsoft/TypeScript#54542 is the root of the OOM. At least, from running on recent TypeScript commits, that's the first one that has the OOM occur. TBD once it's fixed.

Thanks to @jakebailey from the TypeScript team for helping us with this! ❤️

sigh.

One case that would be worth adding a test for:
<foo-bar:baz-bam />

Both the ns and name of the namespace are allowed to be valid JSX identifiers!

Otherwise this is all LGTM
Once you land it we can do an out-of-band release to get it out and keep the early adopters happy!

packages/scope-manager/tests/fixtures/jsx/namespaced-attribute.tsx

+
+// Both of these are equivalent:
+const x = <Foo a:b="hello" />;
+const y = <Foo a : b="hello" />;


cool - this case actually used to be an error pre 5.1!

Oh sorry, I reckon it could be that the secret doesn’t work as an input when you’re coming from a fork…

I will figure out how this has been workable for other actions in the past

JamesHenry · 2023-06-07T10:50:49Z

@JoshuaKGoldberg @bradzacher I can't find any evidence that this ever worked. I think the secret won't be populated on forks which makes sense.

I have therefore just pushed a commit to the branch which should should hopefully amend things to only run the Website Tests when not on a fork

JamesHenry · 2023-06-07T11:20:10Z

I thought that should work based on this answer: https://github.com/orgs/community/discussions/26409#discussioncomment-3251822

anyone know the right syntax here?

bradzacher · 2023-06-07T13:52:24Z

That's all we've got here:

typescript-eslint/.github/workflows/ci.yml

Line 248 in a2b6b2e

    
           if: github.repository == 'typescript-eslint/typescript-eslint' && github.ref == 'refs/heads/main'

IDK why it wouldn't be working there?

bradzacher · 2023-06-07T22:16:45Z

@JoshuaKGoldberg once you've got all the tests passing locally feel free to just land this to main.

We can follow up with a fix commit if any CIs fail on main.

This reverts commit c6f949b.

JoshuaKGoldberg · 2023-06-09T07:00:49Z

Ah, this may be from a different TypeScript issue likely to be fixed soon: microsoft/TypeScript#54542

@JoshuaKGoldberg is the regression going to be patch fixed in 5.1? Or is it going to wait for 5.2?

@jakebailey indicated it should be patched soon

Yeah there will be a patch release of 5.1 in the next day or so.

5.1.6 is out on npm since yesterday, although not visible in https://github.com/microsoft/TypeScript/releases yet.
