eslint-plugin-vue

Official ESLint plugin for Vue.js

🎨 Playground on the Web

You can try this plugin on the Web.

• https://mysticatea.github.io/vue-eslint-demo/

❕ Requirements

• ESLint >=3.18.0.
  • >=4.7.0 to use eslint --fix.
  • >=4.14.0 to use with babel-eslint.
• Node.js >=4.0.0

💿 Installation

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

🚀 Usage

Create .eslintrc.* file to configure rules. See also: http://eslint.org/docs/user-guide/configuring.

Example .eslintrc.js:

module.exports = {
  extends: [
    // add more generic rulesets here, such as:
    // 'eslint:recommended',
    'plugin:vue/essential'
  ],
  rules: {
    // override/add rules settings here, such as:
    // 'vue/no-unused-vars': 'error'
  }
}

Single File Components

ESLint only targets .js files by default. You must include the .vue extension using the --ext option or a glob pattern.

Examples:

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

Attention

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

• Vue.component() expression
• Vue.extend() expression
• Vue.mixin() expression
• export default {} in .vue or .jsx 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>'
}

Vue.component('AsyncComponent', (resolve, reject) => {
  setTimeout(() => {
    // @vue/component
    resolve({
      name: 'async-component',
      template: '<div></div>'
    })
  }, 500)
})

eslint-disable functionality in <template>

You can use <!-- eslint-disable -->-like HTML comments in <template> of .vue files. For example:

<template>
  <!-- eslint-disable-next-line vue/max-attributes-per-line -->
  <div a="1" b="2" c="3" d="4">
  </div>
</template>

If you want to disallow eslint-disable functionality, please disable vue/comment-directive rule.

⚙️ Configs

This plugin provides four predefined configs:

• plugin:vue/base - Settings and rules to enable correct ESLint parsing
• plugin:vue/essential - Above, plus rules to prevent errors or unintended behavior
• plugin:vue/strongly-recommended - Above, plus rules to considerably improve code readability and/or dev experience
• plugin:vue/recommended - Above, plus rules to enforce subjective community defaults to ensure consistency

👫 FAQ

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

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

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

• "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"
  }

The vue-eslint-parser uses the parser which is set by parserOptions.parser to parse scripts.

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": [
    "vue",
-   "html"
  ]

2. 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.
• VSCode targets only JavaScript or HTML files by default. You have to add "vue" to the "eslint.validate" array in vscode settings. e.g. "eslint.validate": [ "javascript", "javascriptreact", "vue" ]
