ember-template-lint-plugin-denylist

An ember-template-lint plugin for setting attribute denylists.

Usage

This plugin allows you to set a denylist for any arbitrary HTML attribute value or values.

Configuration

You can use all the standard ember-template-lint configuration options. For example project wide:

// .template-lintrc.js
module.exports = {
  plugins: ['ember-template-lint-plugin-denylist'],
  extends: ['recommended'],
  rules: {
    denylist: [
      'error',
      {
        attributes: [
          { name: 'alt', values: 'foo' }, // forbid substring 'foo' in 'alt' attributes
          { name: 'class', values: ['^test__', 'bar'] }, // forbid class names starting with 'test__' or containing substring 'bar'
          { name: 'id', values: 'baz$' }, // forbid IDs ending starting with 'baz'
          { name: 'class', values: '$quox$' } // forbid class names exactly matching 'quox'
        ]
      }
    ]
  }
};

Configuration options

attributes

• array -- An array of objects with the following properties:
  • name -- string: HTML attribute to target
  • values -- string|string[]: Value or list of values to forbid
    • Special characters:
      • Prepending a value with ^ only forbids matches from the beginning of a value (e.g., '^foo' matches 'foobar' but not 'barfoo')
      • Suffixing a value with $ only forbids matches from the ending of a value (e.g., 'bar$' matches 'foobar' but not 'barbaz')
      • Combining both special characters forbid only exact matches (e.g., '^foo$' only forbids 'foo')
