eslint-plugin-vuetify-sorting

An ESLint plugin to sort Vuetify classes in a consistent and configurable order, and to catch duplicate classes.

Rules

| Rule | Description | Autofix | | --- | --- | --- | | vuetify-sorting/sort-vuetify-classes | Sorts classes into a configurable category order. | ✅ | | vuetify-sorting/no-duplicate-classes | Flags a repeated class name/key in the same binding (e.g. class="pa-4 d-flex pa-4", or a duplicate :class="{ ... }" key). Both are included in configs.recommended. | ✅ |

Supported Syntax

Applies to both rules above.

• Static class="..." attributes on Vue template elements — sorted and autofixed.
• Static :class="[...]" array bindings, when every element is a plain string literal (e.g. :class="['pa-4', 'd-flex']") — sorted and autofixed.
• :class="{ 'pa-4': true, 'd-flex': isFlex }" object bindings — keys are sorted and autofixed even when values are dynamic, since each key toggles independently and order never affects behavior. Objects with a spread ({ ...base, 'pa-4': true }) or a computed key ({ [dynamicKey]: true }) are left untouched.
• :class array bindings that mix in variables, ternaries, or spreads (e.g. :class="['pa-4', isActive ? 'd-flex' : '']") are left untouched, since reordering could change which class wins under a condition.
• Plain JS/TS string concatenation outside of templates is not covered.

Installation

You can install this plugin directly from this GitHub repository:

npm install eslint-plugin-vuetify-sorting --save-dev

Usage (Flat Config)

In your eslint.config.js:

import vuetifySorting from 'eslint-plugin-vuetify-sorting';

export default [
  // Use the recommended configuration as a SEPARATE entry
  vuetifySorting.configs.recommended,
  
  // Your other rules in a separate config object
  {
    rules: {
      // your other rules...
    }
  }
];

Do not spread vuetifySorting.configs.recommended into another config object using .... This will overwrite the rules from recommended with your own rules object, causing the plugin to silently do nothing. Always pass it as a separate entry in the config array.

Usage with Nuxt (withNuxt)

import withNuxt from './.nuxt/eslint.config.mjs';
import vuetifySorting from 'eslint-plugin-vuetify-sorting';

export default withNuxt(
  // Pass recommended as its own separate argument
  vuetifySorting.configs.recommended,
  {
    rules: {
      // your other rules...
    }
  }
);

Manual configuration (custom order)

import vuetifySorting from 'eslint-plugin-vuetify-sorting';

export default [
  {
    plugins: {
      'vuetify-sorting': vuetifySorting
    },
    rules: {
      'vuetify-sorting/sort-vuetify-classes': ['warn', {
        order: [
          'components',
          'flexGrid',
          'layout',
          'sizing',
          'spacing',
          'typography',
          'visuals',
          'misc'
        ]
      }]
    }
  }
];

Configuration Options

order (optional)

An array of category names or regular expression strings defining the sorting order.

Available Categories (in default order):

• components: matches ^c-, ^o-
• layout: matches ^d-, ^float-, ^position-, ^top-, ^bottom-, ^left-, ^right-, ^z-, ^overflow-, ^clear-
• flexGrid: matches ^flex-, ^justify-, ^align-, ^order-, ^grid-
• sizing: matches ^w-, ^h-, ^min-w-, ^max-w-, ^min-h-, ^max-h-, ^mw-, ^mh-, ^fill-height
• spacing: matches ^[mp][atblrsexy]?-, ^g[axy]-
• typography: matches ^text-, ^font-
• visuals: matches ^bg-, ^border-, ^rounded-, ^elevation-, ^theme--, ^opacity-
• misc: matches ^cursor-, ^pointer-events-, ^user-select-

Classes are matched against these regular expressions directly, so this list can never drift from the rule's actual behavior — run npm run docs after changing defaultGroups/defaultOrder in the rule source to refresh it.

You can also provide custom regular expressions as strings in the order array. For example, to add a custom group for icon classes before spacing:

import vuetifySorting from 'eslint-plugin-vuetify-sorting';

export default [
  {
    plugins: {
      'vuetify-sorting': vuetifySorting
    },
    rules: {
      'vuetify-sorting/sort-vuetify-classes': ['warn', {
        order: [
          'components',
          'layout',
          'flexGrid',
          'sizing',
          '^icon-',       // custom regex: matches classes starting with "icon-"
          'spacing',
          'typography',
          'visuals',
          'misc'
        ]
      }]
    }
  }
];

Classes that do not match any of the defined categories (or custom regexes) are moved to the end of the class list. Within any single category — and among unmatched classes — classes are sorted alphabetically relative to each other.
