vscode ctrl+s自动格式化代码格式

最近在用学习TS，用的vscode工具进行开发保存，由于用vue3.0创建项目时用到了eslint，在保存项目时总是报代码格式错误，一点点改又很麻烦，所以就想到了VScode可以通过配置来实现保存时自动格式化代码，从网上搜了一大堆，在这里整合一下，有不对的地方还请指正

一.先使用vscode下载下面四个插件

1.eslint
2.Prettier - Code formatter
3.Manta's Stylus Supremacy
4.vetur

在这里搜索下载插件

二.修改setting.json配置文件

文件-》首选项-》设置

找到在setting.json里编辑更改配置

  "editor.tabSize": 2,
  "editor.wordWrap": "on",

  ],

    "plaintext",
    "markdown",
    "vue",
    "liquid",
    "erb",
    "lang-cfml",
    "cfml",
    "HTML (Eex)"
  ],
  "minapp-vscode.disableAutoConfig": true,
  "sync.gist": "5f2f2a32094ea38a64ab94308d0dfc07",
  "code-runner.defaultLanguage": "javascript",
  "vsicons.projectDetection.autoReload": true,
  "javascript.updateImportsOnFileMove.enabled": "always",
  "[markdown]": {
    "editor.defaultFormatter": "yzhang.markdown-all-in-one"
  },
  "sync.quietSync": false,
  "sync.removeExtensions": true,
  "sync.syncExtensions": true,
  "sync.autoDownload": false,

  "sync.forceDownload": false,
  "git.ignoreMissingGitWarning": true,
  "editor.suggestSelection": "first",
  "vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue"
}

配置到这时我以为可以了，然而，当我运行项目时一直报双引号单引号的错误

 
     7 | <script lang='ts'>
  >  8 | import { Component, Provide, Vue } from "vue-property-decorator";
       |                                         ^
     9 | @Component({ components: {} })
    10 | export default class About extends Vue {}
    11 | </script>

即使我把双引号改完单引号，但是只要一保存，就自动把单引号编辑为双引号，所以我们需要在根目录下面创建一个文件.prettierrc.json 

内容如下

{
  "printWidth": 100,
  "tabWidth": 2,
  "useTabs": false,
  "singleQuote": false,
  "semi": false,
  "trailingComma": "none",
  "bracketSpacing": true,
  "parser": "babylon"
}

不仅能解决单双引号自动切换问题，还能去除不需要的分号，到这里保存后再运行项目就不会再报格式问题了
