Try out v6 beta on various important community repos

[JoshuaKGoldberg]

V6 is ready for public testing (hooray! https://typescript-eslint.io/blog/announcing-typescript-eslint-v6-beta 🎉) and we want to make sure we try it out on lots of projects. It'd be particularly valuable to try out projects that are:

• Large enough to exercise test cases (think >100 source files)
• Popular enough to get visibility for the v6 beta in front of many people (think >1000 GH stars)

I'm thinking to start, at least:

• Angular (still on TSLint)
• Astro: feat: use typescript-eslint@v6's reworked configs withastro/astro#7425
• Babel: chore: Use typescript-eslint@v6 with reworked configs babel/babel#15716
• create-t3-app: feat: typescript-eslint@v6 t3-oss/create-t3-app#1476
• Prettier (doesn't use our recommended configs)
• Redux: build: use typescript-eslint@v6 internally reduxjs/redux#4566
• Redux Toolkit: build: use typescript-eslint@v6 internally reduxjs/redux-toolkit#3541
• Solid (doesn't lint itself)
• Tanstack (was on my home computer and I had a hard time setting up before traveling - next time maybe!)
• trpc: chore: use typescript-eslint@v6 with reworked configs trpc/trpc#4541
• TypeScript: Updated typescript-eslint to v6 microsoft/TypeScript#54693

For each of these projects, we should see:

• Is someone on their end willing to try things out?
• In addition to version bumps, are they up for recreating their linter configs with the new configs (Changes to configurations for 6.0.0 #6014)?

Filing this tracking issue to make sure we do this before releasing v6 as stable.

If you've got a project that matches those criteria & want to get it added to the list, let us know! We'd be happy to work with you.

Prettier

prettier/prettier#14429

Still waiting for #6723

[JoshuaKGoldberg]

Aside: chatted with @jakebailey today who gave a tentative personal 👍 to at least trying v6 out on the TypeScript codebase. If I have time I'll try to look into overhauling their config to use type-aware rules only in smaller, not-so-performance-killing files (e.g. not src/checker.ts).

#7110 is merged into the v6 branch, #7111 is fixed, and https://www.npmjs.com/package/@typescript-eslint/eslint-plugin/v/6.0.0-alpha.158 is published. I'll start on this now! 🚀

I want give an update here, we (Prettier) can remove all the invalid node checks after upgrade to latest v6, so we can now use parse dirctly instead of parseWithNodeMaps. I think this method was added because Prettier need it at that moment, feel free to remove it if you think it's unnecessary to keep.

I don't know exactly what what we need to update in our configs to try this, but I would happily review a PR trying it out in Babel.

[JoshuaKGoldberg]

Ah amazing thanks @nicolo-ribaudo! I'll send a draft PR :)

Edit: babel/babel#15716

[nickmccurdy]

How about Vite and Vitest (using @antfu/eslint-config)?

[JoshuaKGoldberg]

@nickmccurdy a great idea for next time, thanks!

[JoshuaKGoldberg]

Per sveltejs/kit#10371, looks like Sveltekit would be a good one to add too. :)

Two more for the list:

• Qwik
• Redwood

...I'll put up a GitHub Discussion to keep this existing longer-term.
