# User Guide

# Installation

npm install --save-dev eslint eslint-plugin-vue-scoped-css


  • ESLint v5.0.0 and above
  • Node.js v8.10.0 and above

# Usage

# Configuration

Use .eslintrc.* file to configure rules. See also: https://eslint.org/docs/user-guide/configuring (opens new window).

Example .eslintrc.js:

module.exports = {
  extends: [
    // add more generic rulesets here, such as:
    // 'eslint:recommended',
  rules: {
    // override/add rules settings here, such as:
    // 'vue-scoped-css/no-unused-selector': 'error'

This plugin provides some predefined configs:

  • plugin:vue-scoped-css/base - Settings and rules to enable this plugin
  • plugin:vue-scoped-css/recommended - /base, plus rules for better ways to help you avoid problems for Vue.js 2.x
  • plugin:vue-scoped-css/vue3-recommended - /base, plus rules for better ways to help you avoid problems for Vue.js 3.x
  • plugin:vue-scoped-css/all - All rules of this plugin are included

See the rule list to get the rules that this plugin provides.

# Running ESLint from command line

If you want to run eslint from command line, make sure you include the .vue extension using the --ext option (opens new window) or a glob pattern because ESLint targets only .js files by default.


eslint --ext .js,.vue src
eslint "src/**/*.{js,vue}"

# How to use custom parser?

If you want to use custom parsers such as babel-eslint (opens new window) or @typescript-eslint/parser (opens new window), you have to use parserOptions.parser option instead of parser option. Because this plugin requires vue-eslint-parser (opens new window) to parse .vue files, so this plugin doesn't work if you overwrote parser option.

- "parser": "babel-eslint",
+ "parser": "vue-eslint-parser",
  "parserOptions": {
+     "parser": "babel-eslint",
      "sourceType": "module"

# How ESLint detects components?

All component-related rules are being applied to code that passes any of the following checks:

  • export default {} in .vue file

If you however want to take advantage of our rules in any of your custom objects that are Vue components, you might need to use special comment // @vue/component that marks object in the next line as a Vue component in any file, e.g.:

// @vue/component
const CustomComponent = {
  name: 'custom-component',
  template: '<div></div>'

# Disabling rules via /* eslint-disable */

You can use /* eslint-disable */-like CSS comments in <style> of .vue files to disable a certain rule temporarily.

For example:

<template> <div /> </template> <style scoped> /* eslint-disable-next-line vue-scoped-css/no-unused-selector */ .unknown { color: red; } </style>

# Editor integrations

# Visual Studio Code

Use dbaeumer.vscode-eslint (opens new window) extension that Microsoft provides officially.

You have to configure the eslint.validate option of the extension to check .vue files because the extension targets only *.js or *.jsx files by default.

Example .vscode/settings.json:

  "eslint.validate": [

# Sublime Text

Use SublimeLinter-eslint (opens new window) extension that SublimeLinter provides for eslint.

You have to open command-palette via Cmd/Ctrl+Shift+P and type Preferences: SublimeLinter Settings, paste to the config on the right side:

  "linters": {
    "eslint": {
      "selector": "text.html.vue, source.js - meta.attribute-with-value"

# Atom editor

You need to go into Settings -> Packages -> linter-eslint, under the option "List of scopes to run eslint on", add text.html.vue. You may need to restart Atom.

# IntelliJ IDEA / JetBrains WebStorm

In the Settings/Preferences dialog (Cmd+,/Ctrl+Alt+S), choose JavaScript under Languages and Frameworks and then choose ESLint under Code Quality Tools. On the ESLint page that opens, select the Enable checkbox.

If your ESLint configuration is updated (manually or from your version control), open it in the editor and choose Apply ESLint Code Style Rules on the context menu.

# What is the "Use the latest vue-eslint-parser" error?

The most rules of eslint-plugin-vue-scoped-css require vue-eslint-parser to check <template> ASTs.

Make sure you have one of the following settings in your .eslintrc:

  • "extends": ["plugin:vue-scoped-css/vue3-recommended"]
  • "extends": ["plugin:vue-scoped-css/recommended"]
  • "extends": ["plugin:vue-scoped-css/base"]
  • "extends": ["plugin:vue/recommended"]
  • "extends": ["plugin:vue/base"]

If you already use other parser (e.g. "parser": "babel-eslint"), please move it into parserOptions, so it doesn't collide with the vue-eslint-parser used by this plugin's configuration:

- "parser": "babel-eslint",
  "parserOptions": {
+     "parser": "babel-eslint",
      "ecmaVersion": 2017,
      "sourceType": "module"

See also: "How to use custom parser?" section.

# Why doesn't it work on .vue file?

  1. Make sure you don't have eslint-plugin-html in your config. The eslint-plugin-html extracts the content from <script> tags, but eslint-plugin-vue requires <script> tags and <template> tags in order to distinguish template and script in single file components.
  "plugins": [
-   "html"
  1. Make sure your tool is set to lint .vue files.
  • CLI targets only .js files by default. You have to specify additional extensions by --ext option or glob patterns. E.g. eslint "src/**/*.{js,vue}" or eslint src --ext .vue.
  • If you are having issues with configuring editor please read editor integrations
