Repro Code

I want to apply type-checked rules to most of my codebase with some exceptions. This is the config I have:

ESLint Config

tseslint.config({
    files: ['**/*.{ts,tsx}'],
    ignores: ['libs/legacy-lib/**'],
    extends: [
      ...tseslint.configs.strictTypeChecked,
      ...tseslint.configs.stylisticTypeChecked,
    ],
  })

tsconfig

No response

Expected Result

I expect the final config to have ignores applied to each of the configs I'm extending from.

Actual Result

Only files are applied, not ignores.

Additional Info

I can see from the code that ignores is not supported. This is somewhat surprising, given that files and ignores are two sides of the same coin - the ability to provide a list of files which to apply the rules to.

However, adding this functionality will likely be considered a breaking change.

Versions

typescript-eslint	7.0.1

You have any workaround for this?

You have any workaround for this?

@Flayms - as a temporary workaround, you can manually map over configs as described in the docs - https://typescript-eslint.io/packages/typescript-eslint#flat-config-extends

Using the example from the original issue, the config can be rewritten as follows:

[
  ...tseslint.configs.strictTypeChecked,
  ...tseslint.configs.stylisticTypeChecked,
].map(conf => ({
  ...conf,
  files: ['**/*.{ts,tsx}'],
  ignores: ['libs/legacy-lib/**'],
}))

However, I hope that the fix (#8567) will be merged this week, so that a new version containing it will be released next Monday.

This will release next monday as per our release schedule.
Until that time you can use the canary version
