  1.vscode + ESLint保存自动修改代码

不管是多人合作还是个人项目,代码规范是很重要的。这样做不仅可以很大程度地避免基本语法错误,也保证了代码的可读性。这所谓工欲善其事,必先利其器,个人推荐 eslint+vscode 来写 vue,绝对有种飞一般的感觉。效果如图:

 

每次保存,vscode就能标红不符合eslint规则的地方,同时还会做一些简单的自我修正。安装步骤如下:

 

首先安装eslint插件、

安装并配置完成 ESLint 后,我们继续回到 VSCode 进行扩展设置,依次点击 文件 > 首选项 > 设置 打开 VSCode 配置文件,添加如下配置

{
   "editor.tabSize": 2,
   "files.associations": {
       "*.vue": "vue"
   },
   "eslint.autoFixOnSave": true,
   "eslint.options": {
       "extensions": [
           ".js",
           ".vue"
       ]
   },
 "eslint.validate": [
     "javascript",{
         "language": "vue",
         "autoFix": true
     },"html",
     "vue"
 ],
   "search.exclude": {
       "**/node_modules": true,
       "**/bower_components": true,
       "**/dist": true
   },
   "emmet.syntaxProfiles": {
       "javascript": "jsx",
       "vue": "html",
       "vue-html": "html"
   },
   "git.confirmSync": false,
   "window.zoomLevel": 0,
   "editor.renderWhitespace": "boundary",
   "editor.cursorBlinking": "smooth",
   "editor.minimap.enabled": true,
   "editor.minimap.renderCharacters": false,
   "editor.fontFamily": "'Droid Sans Mono', 'Courier New', monospace, 'Droid Sans Fallback'",
   "window.title": "${dirty}${activeEditorMedium}${separator}${rootName}",
   "editor.codeLens": true,
   "editor.snippetSuggestions": "top",
 }

项目ESLint安装并开启、eslint-plugin-vue 、eslint-plugin-html、安装在ESLint一起 都全局或者都装在项目里

这样每次保存的时候就可以根据根目录下.eslintrc.js你配置的eslint规则来检查和做一些简单的fix。

再提供个我的.eslintrc.js配置(注意ESLint期望的格式 可能与vscode格式化的格式不一致 需要统一风格)

TIPS:vue-cli3.0 可以通过vue ui界面直接设置eslint规则、而不用在配置 .eslintrc.js文件了

2.ctrl+` 可以呼出调试终端 集成了git powershell功能

3.ctrl+shift+G 开启git 源代码管理 可比较差异

4.常用vscode 插件:vutur  ESLint  Chinese
