vue+ESLint 配置保存 自动格式化代码

1. 在.eslintrc.js 添加 vscode 终端启动服务

// 添加⾃定义规则
 'prettier/prettier': [
  // eslint校验不成功后，error或2则报错，warn或1则警告，off或0则⽆提示
  'error',
  {
  singleQuote: true,
  semi: false, //结束是否加分号
  printWidth: 160//每行最长字符 
  }
 ]

2.打开VS code 文件》首选项》设置》扩展》ESLint》

// eslint格式化字符串
 "editor.codeActionsOnSave": {
  "source.fixAll.eslint": true
 },

如果编译 发现以下错误

warning delete ·· (prettier/prettier) “error Delete ⏎ prettier/prettier” in .vue files

解决

在vuejs项目中，运行如下命令解决：

npm run lint ? --fix

如果还是没行，就要在 vue.config.js 添加

// vue.config.js

// 旧 data: @import "~@/assets/scss/variables.scss"; // 新 prependData: @import ~@/assets/scss/variables.scss;

module.exports = {
 chainWebpack: config => {
 config.module
  .rule('eslint')
  .use('eslint-loader')
  .loader('eslint-loader')
  .tap(options => {
  options.fix = true
  return options
  })
 }
}
