Possible bug? Eslint plugins/extensions specified in override somehow overflows

[ghost]

Hello Eslint community,

In my project, I've split the eslint config into to sections by applying different rules/configs to *.js and *.ts. It looks like this:

/** @type {import('eslint').Linter.Config} */
const typescriptConfig = {
  env: {
    node: true,
    es2020: true,
    jest: true,
  },
  parser: '@typescript-eslint/parser',
  parserOptions: {
    project: './tsconfig.json',
    ecmaVersion: 2020,
  },
  plugins: ['sonarjs', 'jest', 'simple-import-sort', 'prettier'],
  extends: [
    'airbnb-typescript/base',
    'plugin:@typescript-eslint/recommended',
    'plugin:@typescript-eslint/recommended-requiring-type-checking',
    'plugin:jest/recommended',
    'plugin:node/recommended-script',
    'plugin:sonarjs/recommended',
    'prettier',
  ],
  rules: {
    'prettier/prettier': 'error',
    'simple-import-sort/imports': 'error',
    'simple-import-sort/exports': 'error',
    'node/no-unsupported-features/es-syntax': [
      'error',
      { ignores: ['modules'] },
    ],
    'no-console': 'off',
  },
  settings: {
    node: {
      tryExtensions: ['.ts'],
    },
  },
};

/** @type {import('eslint').Linter.Config} */
const javascriptConfig = {
  env: {
    commonjs: true,
    es6: true,
    node: true,
  },
  extends: ['airbnb-base'],
  parserOptions: {
    ecmaVersion: 2020,
  },
};

/** @type {import('eslint').Linter.Config} */
module.exports = {
  root: true,
  overrides: [
    {
      files: '*.ts',
      ...typescriptConfig,
    },
    {
      files: '*.js',
      ...javascriptConfig,
    },
  ],
};

As you can see, I've reserved most of the plugins/rules to typescript files. But for some reason, the eslint-plugin-import rules are still applied to javascript files.

You can see this when I run yarn eslint --print-config scripts/build.js >> eslint.json:

...
    }
  },
  "plugins": [
    "import"
  ],
  "rules": {
    "strict": [
...

So, ehm, why is this? Can I not specify plugins/extensions based on glob pattern?

Check that the rules aren’t being enabled in one of the configs you have in “extends”
