vue-cli构建的项目如何手动添加eslint配置

package.json里配置添加

1.scripts里添加快捷eslint检查命令

"lint": "eslint --ext .js,.vue src"

2.添加eslint依赖包

"babel-eslint": "^8.2.1",
  "eslint": "^4.15.0",
  "eslint-config-standard": "^10.2.1",
  "eslint-friendly-formatter": "^3.0.0",
  "eslint-loader": "^1.7.1",
  "eslint-plugin-import": "^2.7.0",
  "eslint-plugin-node": "^5.2.0",
  "eslint-plugin-promise": "^3.4.0",
  "eslint-plugin-standard": "^3.0.1",
  "eslint-plugin-vue": "^4.0.0",

根目录下添加检测配置js文件.eslintrc.js

// 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'
 }
}

添加忽略检测配置文件.eslintignore

/build/
/config/
/dist/
/*.js

webpack.base.conf.js rules里添加eslint-loader配置

const createLintingRule = () => ({
 test: /\.(js|vue)$/,
 loader: 'eslint-loader',
 enforce: 'pre',
 include: [resolve('src'), resolve('test')],
 options: {
  formatter: require('eslint-friendly-formatter'),
  emitWarning: !config.dev.showEslintErrorsInOverlay
 }
})
module.exports = {
 //.......
 module: {
  rules: [
   ...(config.dev.useEslint  [createLintingRule()] : []),
  //.....

config->index.js的dev里添加

useEslint: true,
showEslintErrorsInOverlay: false,

Eslint的一些规则说明

1.使用Eslint的时候如果出现未闭合标签会报红

如下：

对于有强迫症的我来说不能无视，怎么搞定？

首先找到.eslintrc.js文件

在 rules添加以下规则

"vue/html-self-closing": ["error",{
  "html": {
    "void": "never",
    "normal": "any",
    "component": "any"
  },
  "svg": "always",
  "math": "always"
}],

保存即可

2.需要在单行元素的内容之前和之后换行

规则：

"vue/singleline-html-element-content-newline": false,

以上为个人经验，希望能给大家一个参考，也希望大家多多支持源码搜藏网。
