本文以vue项目举例
一、安装 Eslint
安装eslint插件
二、安装 Prettier-Code formatter插件
需要安装这个 代码格式化插件
否则会提示 Extension 'esbenp.prettier-vscode' is configured as formatter but not available. Select a different default formatter to continue.
三、安装Vetur插件
四、配置 setting.json
找到File > Preference > Settings > Text Editor > Code Actions On Save > Edit in setting.json打开进行编辑
添加如下的配置到你的setting.json (这个注释很全就不过得解释了)
{
"workbench.startupEditor": "newUntitledFile",
"window.zoomLevel": 1, // window be show of level in ide
"git.ignoreMissingGitWarning": true,
"explorer.confirmDelete": false,
// "workbench.colorTheme": "Monokai", //vsc 配色

},
},
"docthis.authorName": "tomAnny",
"docthis.includeDescriptionTag": true,
"docthis.includeDateTag": true,
"docthis.includeAuthorTag": true,
"vsicons.dontShowNewVersionMessage": true,
"terminal.integrated.rendererType": "dom",
// vscode默认启用了根据文件类型自动设置tabsize的选项
"editor.detectIndentation": false,
// 重新设定tabsize
"editor.tabSize": 2,
// #每次保存的时候自动格式化
"editor.formatOnSave": true,
"editor.formatOnType": true,
// 强制单引号
"prettier.singleQuote": false,

// 尽可能控制尾随逗号的打印
"prettier.trailingComma": "all",
// #这个按用户自身习惯选择-- prettier 或者js-beautify-html
"vetur.format.defaultFormatter.html": "js-beautify-html",
// #让vue中的js按编辑器自带的ts格式进行格式化
"vetur.format.defaultFormatter.js": "vscode-typescript",
"html.format.indentHandlebars": true,
"javascript.preferences.quoteStyle": "single",
"typescript.preferences.quoteStyle": "single",
"html.format.enable": false,
"html.format.preserveNewLines": false,
"diffEditor.ignoreTrimWhitespace": false,
"vetur.format.defaultFormatterOptions": {
"js-beautify-html": {
"wrap_attributes": "force-aligned"
// #vue组件中html代码格式化样式
}
},
//防止VSCode启动带有node_modules的项目的时候很卡的问题
"search.followSymlinks": false,
"files.autoSave": "onWindowChange",
"[vue]": {
"editor.defaultFormatter": "octref.vetur"
//"editor.defaultFormatter": "esbenp.prettier-vscode"
},
"[javascript]": {
"editor.defaultFormatter": "HookyQR.beautify"
},
"[scss]": {
"editor.defaultFormatter": "HookyQR.beautify"
},

"editor.defaultFormatter": "HookyQR.beautify"

"editor.defaultFormatter": "HookyQR.beautify"
},
// #每次保存的时候将代码按eslint格式进行修复
"editor.codeActionsOnSave": {
"source.fixAll.eslint": true
},
}
(ps 需要注意的一点)
这样设置后,vue中template(html) 在保存后(ctrl s)会将每个属性都自动换行,可以按以下设置修改,避免过多的换行,注意不要有重复的配置
"vetur.format.defaultFormatter.html": "js-beautify-html",
"vetur.format.defaultFormatterOptions": {
"js-beautify-html": {
"wrap_attributes": "auto",
/*auto: 仅在超出行长度时才对属性进行换行。
force: 对除第一个属性外的其他每个属性进行换行。
force-aligned: 对除第一个属性外的其他每个属性进行换行,并保持对齐。
force-expand-multiline: 对每个属性进行换行。
aligned-multiple: 当超出折行长度时,将属性进行垂直对齐。*/
"wrap_line_length": 220,//超过多少字符换行
"end_with_newline": false, //是否用换行符结束
"indent_size": 2, //缩进大小
"indent_char": " ", //缩进字符
"indent_with_tabs": false,
"eol": "\n", // 用作行终止的字符,默认为\n
"preserve_newlines": true, // 是否保留现有的换行符
"max-preserve-newlines": 40, // 一次可保留的最大换行数
"indent-inner-html": true, //缩进 head body代码片段
"editorconfig": false //使用editorconfig设置选项
}
},
五、配置 .eslintrc.js
现在需要将项目中对应的elsintrc.js
配置一下,来规范整个项目的代码风格,避免团队人员多了,代码五花八门,
个人配置大概如下:
module.exports = {
root: true,
parserOptions: {
parser: 'babel-eslint',
sourceType: 'module'
},
env: {
browser: true,
node: true,
es6: true,
},
extends: ['plugin:vue/recommended', 'eslint:recommended'],
// add your custom rules here
//it is base on https://github.com/vuejs/eslint-config-vue
rules: {
"vue/max-attributes-per-line": [2, {
"singleline": 10,
"multiline": {
"max": 1,
"allowFirstLine": false
}
}],

"vue/multiline-html-element-content-newline":"off",
"vue/name-property-casing": ["error", "PascalCase"],

}
}
六、项目根目录配置 .editorconfig
再配置一个代码 空格,缩进、换行等规范
看看官方对这个editor
的介绍
# https://editorconfig.org
root = true
[*]
charset = utf-8
indent_style = space
indent_size = 2
end_of_line = lf
insert_final_newline = true
trim_trailing_whitespace = true
[*.md]
insert_final_newline = false
trim_trailing_whitespace = false
都配置好后,下次ctrl+S 保存文件,就会自动进行格式化了。
