vscode中配置eslint+vetur+prettier實現儲存時自動格式化並修復

首先安裝vscode的elinst、vetur、prettier外掛

然後設定setting.json檔案

{
  "sync.autoDownload": false,
  "sync.autoUpload": false,
  "sync.gist": "95334f62cb3f660374fb11d0603264bd",

  "editor.renameOnType": true,
  "editor.renderIndentGuides": false,
  "vsicons.projectDetection.autoReload": true,
  "vsicons.dontShowNewVersionMessage": true,
  "workbench.colorTheme": "Visual Studio Dark",
  "search.followSymlinks": false,
  "git.autofetch": true,
  "window.zoomLevel": 1,
  "git.enableSmartCommit": true,
  "liveServer.settings.donotShowInfoMsg": true,
  "files.autoSave": "afterDelay", // 開啟自動儲存

    "strings": true
  },
  "editor.detectIndentation": false, // vscode預設啟用了根據檔案型別自動設定tabsize的選項
  "editor.tabSize": 2, //製表符符號eslint
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "eslint.run": "onSave",
  "eslint.validate": ["javascript", "javascriptreact", "vue", "html"],
  "eslint.autoFixOnSave": true,
  "editor.codeActionsOnSave": {
    "source.fixAll": false,
    "source.fixAll.eslint": true //儲存自動修復, eslint.autoFixOnSave已廢棄
  },


  "prettier.useTabs": false, //使用製表符縮排
  "prettier.semi": false, //去掉程式碼結尾的分號
  "prettier.singleQuote": true, //使用單引號替代雙引號
  "prettier.trailingComma": "none", //去除物件最末尾元素跟隨的逗號
  "prettier.printWidth": 200, //指定程式碼長度，超出換行
  "prettier.requireConfig": false, //需要prettier.requireConfig格式化
  "prettier.useEditorConfig": false,
  "prettier.eslintIntegration": true, //不讓prettier使用eslint的程式碼格式進行校驗


  "javascript.format.insertSpaceBeforeFunctionParenthesis": true, //讓函式(名)和後面的括號之間加個空格
  "vetur.format.defaultFormatter.html": "js-beautify-html", //格式化.vue中html
  "vetur.format.defaultFormatter.js": "vscode-typescript", //讓vue中的js按編輯器自帶的ts格式進行格式化
  "vetur.format.defaultFormatterOptions": {
    "js-beautify-html": {
      "wrap_attributes": "force-aligned" //屬性強制折行對齊
    }
  }
}
