vsCode配置ESlint自动格式化、修复代码

梦里梦外; 2022-11-11 05:22 683阅读 0赞

1.使用vscode安装 eslint + vuter + prettier自动格式化代码配置;  
2.文件—首选项—设置—用户设置>搜索"settings" 找到并点击“在settings.json中编辑”  
3.把下面这段代吗复制到**settings.json**文件里面 我在这个文章里找的 [文章链接][Link 1]

{ 
            "workbench.editor.enablePreview": false, //打开文件不覆盖
            "search.followSymlinks": false, //关闭rg.exe进程
            "editor.minimap.enabled": false, //关闭快速预览
            "liveServer.settings.donotShowInfoMsg": true, //关闭liveserver提示
            "files.autoSave": "afterDelay", //打开自动保存
            "editor.fontSize": 16, //设置文字大小
            "editor.lineHeight": 24, //设置文字行高
            "editor.lineNumbers": "on", //开启行数提示
            "editor.quickSuggestions": {  //开启自动显示建议
                "other": true,
                "comments": true,
                "strings": true
            },
            "workbench.colorTheme": "Darcula Theme from IntelliJ", //指定工作台中使用的颜色主题
            "window.zoomLevel": 0, // 调整窗口的缩放级别
            "editor.tabSize": 2, //制表符符号eslint
            "editor.formatOnSave": true, //每次保存自动格式化
            "eslint.autoFixOnSave": true, // 每次保存的时候将代码按eslint格式进行修复
            "prettier.eslintIntegration": true, //让prettier使用eslint的代码格式进行校验
            "prettier.semi": false, //去掉代码结尾的分号
            "prettier.singleQuote": true, //使用带引号替代双引号
            "javascript.format.insertSpaceBeforeFunctionParenthesis": true, //让函数(名)和后面的括号之间加个空格
            "vetur.format.defaultFormatter.html": "js-beautify-html", //格式化.vue中html
            "vetur.format.defaultFormatter.js": "vscode-typescript", //让vue中的js按编辑器自带的ts格式进行格式化
            "vetur.format.defaultFormatterOptions": { 
                "js-beautify-html": { 
                    "wrap_attributes": "force-aligned" //属性强制折行对齐
                }
            },
            "eslint.validate": [ //开启对.vue文件中错误的检查
                "javascript",
                "javascriptreact",
                { 
                    "language": "html",
                    "autoFix": true
                },
                { 
                    "language": "vue",
                    "autoFix": true
                }
            ],
        }

把这段代码粘进去就行了 可根据自己喜好更改，在编写代码的时候是就会根据自己项目文件下的\*\*.eslintrc.js\*\*文件下的规则进行格式化  
如果没有这个文件说明你的项目没有装eslint的插件去装下[eslint-npm][]，然后把下面的代码复制进去  
**注：**(这里只是自己喜欢的风格，每个人和团队都有自己的代码规范，统一就好了，去打造一份属于自己的eslint 规则上传到npm吧，如饿了么团队的 [eslint-npm][eslint-npm 1]，vue的 [eslint-npm][eslint-npm 2]。来自花裤衩手摸手系列的一句话)
