這篇文章主要介紹了vue?如何配置eslint代碼檢查，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

1.安裝依賴

"eslint": "^5.12.0",
"eslint-config-standard": "^12.0.0",
"eslint-friendly-formatter": "^4.0.1",
"eslint-loader": "^2.1.1",
"eslint-plugin-import": "^2.14.0",
"eslint-plugin-node": "^8.0.1",
"eslint-plugin-promise": "^4.0.1",
"eslint-plugin-standard": "^4.0.0",
"eslint-plugin-vue": "^5.1.0",
"acorn": "^6.0.5",
"babel-eslint": "^8.2.1",

2.webstorm代碼格式化快捷鍵為win + alt + L

在webstorm preference里面找到code style，在里面設(shè)置webstorm代碼快捷格式化選項。

比如這里勾選上in empty tag時，當我們按win + alt + L格式化代碼時，就會自動在閉合標簽前面添加空格。

如果webstorm格式化與eslint規(guī)則沖突，大多時候也可以從這里設(shè)置規(guī)則。

3.設(shè)置webstorm校驗規(guī)則為本地項目安裝的eslint

如下：

4.在項目本地新建.editorconfig文件

設(shè)置webstorm格式。

root = true
 
[*]
charset = utf-8
indent_style = space
indent_size = 2
end_of_line = lf
insert_final_newline = true
trim_trailing_whitespace = true
in_empty_tag = true

5.在項目本地新建.eslintrc.js文件

// https://eslint.org/docs/user-guide/configuring
 
module.exports = {
  root: true,
  parserOptions: {
    parser: 'babel-eslint'
  },
  env: {
    browser: true,
  },
  extends: [
    // https://github.com/vuejs/eslint-plugin-vue#priority-a-essential-error-prevention
    // consider switching to `plugin:vue/strongly-recommended` or `plugin:vue/recommended` for stricter rules.
    'plugin:vue/essential',
    // https://github.com/standard/standard/blob/master/docs/RULES-en.md
    'standard'
  ],
  // required to lint *.vue files
  plugins: [
    'vue'
  ],
  // add your custom rules here
  rules: {
    // allow async-await
    'generator-star-spacing': 'off',
    // allow debugger during development
    'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off',
