Body

Just some feedback. The documentation needs to be clearer.

Please consider this eslint config:

// @ts-check
import turbo from 'eslint-config-turbo/flat';
import tseslint from 'typescript-eslint';

export default tseslint.config(
  ...turbo,
  {
    // ...other irrelevant config
  }
);

It reports this error:

Argument of type '{ plugins: { turbo: typeof plugin; }; rules: { "turbo/no-undeclared-env-vars": string; }; }' is not assignable to parameter of type 'InfiniteDepthConfigWithExtends'.
  Types of property 'rules' are incompatible.
    Type '{ "turbo/no-undeclared-env-vars": string; }' is not assignable to type 'Partial<Record<string, RuleEntry>>'.
      Property '"turbo/no-undeclared-env-vars"' is incompatible with index signature.
        Type 'string' is not assignable to type 'RuleEntry | undefined'.ts(2345)

I have no way of knowing how to actually do this. The documentation doesn't go beyond the simplest possible scenario, and fails to consider basically anything else.

I can't just do turbo as ConfigWithExtends or whatever, because ESLint requires the config to be a javascript file. So in fact there's literally nothing I can add to make typescript understand what it's importing.

And also, I'm not the author of eslint-config-turbo so I can't just add typings to it. But moreover, you can't expect every author of every eslint config package to provide their typings.

Afaict, this is placing me between a rock and a hard place. Please update the documentation with more scenarios like this one.

Sorry about my last topic. I didn't know I wasn't allowed to ask about a problem - I consider that feedback. Kinda rude to close it without allowing me to explain myself, so I just created a new discussion, more clearly formulating it as feedback. Please do not close and lock 🙏🏻
