To be clear, this is not a bug - the types are correct - but you're right they could be more helpful.

Just to share a workaround for Typescript users until we figure out how to type the configs properly

// @ts-expect-error https://github.com/jsx-eslint/eslint-plugin-react/issues/3878
reactPlugin.configs.flat.recommended,

As a workaround, I added a .d.ts file to fix original types which are too loose:

// eslint-plugin-react.d.ts
declare module 'eslint-plugin-react' {
  export const configs: typeof configs & {
    flat: Record<'all' | 'recommended' | 'jsx-runtime', ReactFlatConfig>; // the original type is Record<string, ReactFlatConfig>
  };
}

This could be a fix for this lib but I see there is already an open PR. I can propose this fix in another PR if it makes sense

Please don’t open an additional PR; if you have a fix that could work, please post a link to the branch on the existing PR.

The fix is just there. The branch is more a refactor with a breaking change, this is why I offered to create a simpler PR with the mentioned typing fix.

Since our types are built, that isn’t a possible fix we can apply, unfortunately.

I don't understand, if your types are generated from the JSDocs, then the fix seems pretty simple; Change Record<string, ReactFlatConfig> to Record<'all' | 'recommended' | 'jsx-runtime', ReactFlatConfig> here:

Or am I missing something?

@3dos There were two attempts to fix this issue, #3879 and #3882, #3879 was taking the same approach as yours and it didn't work due to #3879 (comment), you could try it yourself by applying your changes locally and test it through #3879 (comment)
