VSCODE 配置eslint规则和自动修复

  • vscode安装以下插件

    EsLint、vetur、Prettier - Code formatter

  • vscode设置了添加配置项,,默认会去查找你项目中的eslint配置文件
      "workbench.iconTheme": "material-icon-theme",
      "explorer.confirmDragAndDrop": false,
      "explorer.confirmDelete": false,
      "eslint.autoFixOnSave": true,  //  启用保存时自动修复,默认只支持.js文件
      "eslint.validate": [
         "javascript",  //  用eslint的规则检测js文件
           "language": "vue",   // 检测vue文件
           "autoFix": true   //  为vue文件开启保存自动修复的功能
           "language": "html",
           "autoFix": true
  • 项目中创建.eslitrc.js配置 文件,可能比较多

    Good post made here. One thing I would like to say is the fact that most professional job areas consider the Bachelor’s Degree like thejust like the entry level standard for an online course. When Associate Diplomas are a great way to begin, completing the Bachelors starts up many entrances to various occupations, there are numerous online Bachelor Diploma Programs available from institutions like The University of Phoenix, Intercontinental University Online and Kaplan. Another concern is that many brick and mortar institutions provide Online types of their certifications but typically for a substantially higher payment than the institutions that specialize in online higher education degree plans.
