Dynamic languages like Ruby, Python, and JavaScript determine the types of variables at runtime rather than at compile time. This flexibility allows for rapid development and concise code, but it also...

Yeah. This has come up more and more over the last couple of years as folks -including us in typescript-eslint- have run into those limitations.

We put up a tl;dr + medium dive here that I think might be useful to know:

Typed linting optimizations blocked by ESLint core · Issue #11677 · typescript-eslint/typescript-eslint

Suggestion tl;dr: We get asked pretty frequently about improving the state of cross-file linting, e.g. typed linting, in ESLint core. Most requests are around performance. Others are around core ES...

It's been 8 hours and I don't think Copilot might not get back to this PR... That outage today really did a number on the bots.

Kirk was working on that but it's *really* tricky. The cross-plugin types situation post-ESLint-core-starting-their-types-work is kind of a mess right now 🫠

❤️ I love this, thank you for saying something!! We've had & seen a lot of pain there too, and wanted to help. Yay!

Josh Ghoulberg 👻 @joshuakgoldberg.com · 7d

Totally understood, thanks!!

And if your project isn't the kind to have paying customers? Let's say you're wholly indie (no paying job), you work on shared dev tooling like linters, test runners, etc. The kinds where *everything* is free, by nature, and should be.

> If open source maintainers are burning out, that's on them for saying "yes" too often.

(genuinely asking, not confronting) If I don't say "yes" a high amount, I don't make enough $. My income as a full-time indie maintainer is tied to exposure, hourly invoices, etc. How do you account for that?

Josh Ghoulberg 👻 @joshuakgoldberg.com · 7d

Can you try swapping over from tseslint.config to ESLint's defineConfig? If that breaks, what's wrong?

Josh Ghoulberg 👻 @joshuakgoldberg.com · 7d

👋 tseslint maintainer here. tseslint.config works fine. The one from eslint/config is roughly the same, but newer. We want to defer to core ESLint APIs whenever possible.

ESLint's defineConfig is pretty much a drop-in replacement. We've never seen a real-world case of folks blocked from migrating.

I would put a link to the issue in the comment so folks don't see it as a "broken window" that ts-expect-error wtf is common practice. But yeah for a short-term thing like this it's reasonable.

If you want to be extra you could copy & paste the types into a .d.ts file? 🤷 probably not worth it imo

Josh Ghoulberg 👻 @joshuakgoldberg.com · 8d

for the most part they just give you nice types: both for intellisense and if you type check your eslint config file

they also add a few niceties around extends. the eslint one does a little more now

could be a good docs issue, I can't find much on the websites
