VSCode：代码格式化插件

settings.json文件中添加如下配置并保存 

{
    "workbench.sideBar.location": "left",
    "cssrem.rootFontSize": 80,
    "git.ignoreWindowsGit27Warning": true,
    "eslint.codeAction.showDocumentation": {
      "enable": true
    },
    //改变注释颜色
    // "editor.tokenColorCustomizations": {
    //   "comments": "#ff4f81" // 注释
    // }, 
      
      //导入文件时是否携带文件的扩展名
      "path-autocomplete.extensionOnlmport": true,
      //配置@的路径提示
      "path-autocomplete.pathMappings": {
          "@": "${folder}/src"
      },
    //配置eslint
    "eslint.validate": ["javascript", "javascriptreact", "html", "vue"],
    // "eslint.run": "onSave",
    "editor.codeActionsOnSave": {
      "source.fixAll.eslint": "explicit"
    },
    "editor.mouseWheelZoom": true,
    "editor.minimap.renderCharacters": false,
    "debug.javascript.defaultRuntimeExecutable": {
      "pwa-node": "node"
    },
    "open-in-browser.default": "{\"open-in-browser.default\":\"Chrome\"}",
    "files.associations": {
      "*.cjson": "jsonc",
      "*.wxss": "css",
      "*.wxs": "javascript"
    },
    "emmet.includeLanguages": {
      "wxml": "html"
    },
    "minapp-vscode.disableAutoConfig": true,
    "[python]": {
      "editor.formatOnType": true
    },
    "editor.detectIndentation": false,
    "explorer.compactFolders": false,
    // html使用prettier格式化
    "[html]": {
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[vue]": {
      // "editor.defaultFormatter": "Vue.volar"
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[javascript]": {
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[typescript]": {
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    // json使用prettier格式化
    "[json]": {
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[jsonc]": {
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "editor.tabSize": 2,
    "[scss]": {
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "px2rem.rootFontSize": 64,
    "px2rem.autoRemovePrefixZero": false,
    "editor.formatOnSave": true // 保存时自动规范代码
  }

然后重启工具，当保存的时候就会自动格式化~~
