  extends: ['plugin:naming/recommended'],
};

Type: string

You can set the match option like this:

module.exports = {
  extends: ['plugin:naming/recommended'],
  rules: {
    'naming/case': ['error', 'kebab'],
  },
};

Type: {string[]}

You can set the match option to allow multiple cases:

module.exports = {
  extends: ['plugin:naming/recommended'],
  rules: {
    'naming/case': ['error', ['kebab', 'camel']],
  },
};

Options object has the following properties:

Example

module.exports = {
  extends: ['plugin:naming/recommended'],
  rules: {
    'naming/case': [
      'error',
      {
        match: 'kebab',
        ignore: ['^FOOBAR\\.js$', '^(B|b)az', '\\.SOMETHING\\.js$', /^vendor/i],
      },
    ],
  },
};

Don't forget that you must escape special characters that you don't want to be interpreted as part of the regex, for example, if you have [ in the actual filename. For example, to match [id].js, use /^\[id]\.js$/ or '^\\[id]\\.js$'.
