ESLint is ignoring .vue files

Hello and thank you for this wonderful plugin. Tell us about your environment

• ESLint Version:. 4.12.1
• eslint-plugin-vue Version: 4.0.1
• Node Version: 8.9.3

Please show your full configuration:

module.exports = {
  root: true,
  extends: 'standard',
  // extends: [
  //   'eslint:standard',
  //   'plugin:vue/essential'
  // ],
  parserOptions: {
    sourceType: 'module',
  },
  plugins: [
    'vue'
  ],
  env: {
    browser: true,
    commonjs: true,
    es6: true,
    jest: true,
    node: true
  },
  rules: {
    'no-console': 0,
    'no-undef': 0,
    'semi': [2, 'always'],
    'space-before-function-paren': 0,
    'object-property-newline': 0
  }
}

What did you expect to happen? With this config, ESLint is linting only .js files on every save and that’s my wanted behavior but also with .vue files in the src folder. When I try uncommenting the extends array, it does not work.

What actually happened? Please include the actual, raw output from ESLint. ESLint is throwing the classic ELIFECYCLE error with the current config. It was linting .js files in the root folder, but I can’t manage to make it work with .vue files. Also tried eslint-plugin-html, but the documentation said it can have onflicts with this plugin so I kicked it out of the project.

Our README.md mentions eslint:recommended embedded preset. On the other hand, standard is a shorthand of eslint-config-standard, and eslint:standard doesn’t exist.

The .eslintrc file does not control target files. Target files are decided by how eslint runs. For example, the CLI ./node_modules/.bin/eslint "src/**/*.{js,vue}" will lint .js and .vue files in src folder. If you use editor integrations, I think there is an editor setting to run ESLint on .vue files. For example, vscode needs the following setting:

{
    "eslint.validate": [
        "javascript",
        "javascriptreact",
        {"language": "vue", "autoFix": true}
    ]
}

Also you can use --ext flag while running eslint command:

eslint src --ext .js,.vue
