Align types with ESLint

I'm getting the following errors with skipLibCheck: false:

    The expected type comes from property 'rules' which is declared here on type 'FlatConfig'

I'm using a flat config, but I don't think that's the reason.

I don't really understand what you mean by problem. The types provided by this plugin are of no use to anyone other than the person writing the plugin.
Are you asking to remove d.ts from this plugin? If not, please provide a repository that reproduces the problem.

No, the presence of .d.ts is appreciated.

Hmm, I'm just a user, and they're useful to me. My eslint.config.js is type-checked, because I like being told by TypeScript when I don't put something in the right spot, which happens relatively often.

If not, please provide a repository that reproduces the problem.

Sure! Here: https://github.com/alecmev/eslint-plugin-jsonc-repro-309 Run npm i and then npx tsc.

After switching to typescript-eslint's types, as per typescript-eslint/typescript-eslint#8613 (comment), the error around plugin goes away, but not rules.

[ota-meshi]

I checked, and I think it's a bug in @types/eslint. The @types/eslint type definition cannot accept nodes other than @types/estree, but eslint can accept extended nodes.

Doesn't DefinitelyTyped/DefinitelyTyped#68232 help?

[alecmev]

I think the problem is that string just isn't specific enough. It should be "error" | "warn" | "off", or even just the exact value, which is "error" in this case.

[JounQin]

as const would help then.

This should be fixed in #322
