引言
????在vue-cli官方的脚手架创建项目时,会自动让选择Eslint+Prettier,如果是老项目想接入,那么按照下面步骤接入即可
eslint安装
npm i -D eslint eslint-loader babel-eslint eslint-plugin-vue @vue/cli-plugin-eslint
eslint配置
????在项目的根目录下,新建.eslintrc.js文件,并将下面代码拷贝进去

????在项目的根目录下,新建.eslintignore文件,配置要忽略的文件
build
node_modules
public
prettier安装
npm i -D prettier eslint-plugin-prettier eslint-config-prettier prettier-eslint-cli
prettier配置
????在项目的根目录下,新建.prettierrc.js文件,并将下面代码拷贝进去
module.exports = {
printWidth: 160,
semi: false,
singleQuote: true,
jsxSingleQuote: false,
trailingComma: 'none',
bracketSpacing: true,
jsxBracketSameLine: false,
arrowParens: 'avoid',
insertPragma: false,
tabWidth: 2,
useTabs: false,
endOfLine: 'auto',
HTMLWhitespaceSensitivity: 'ignore'
}
vscode插件安装
????安装Eslint、Prettier、Vetur插件
vscode配置
????找到eslint的settings.json文件,并将下面代码拷贝进去
{
"editor.detectIndentation": false,
"editor.tabSize": 2,
"editor.formatOnSave": true,
"eslint.autoFixOnSave": true,
"eslint.validate": [
"javascript",
"javascriptreact",
{
"language": "vue",
"autoFix": true
}
],
"prettier.eslintIntegration": true,
"prettier.semi": false,
"prettier.singleQuote": true,
"javascript.format.insertSpaceBeforeFunctionParenthesis": true,
"stylusSupremacy.insertColons": false,
"stylusSupremacy.insertSemicolons": false,
"stylusSupremacy.insertBraces": false,
"stylusSupremacy.insertNewLineAroundImports": false,
"stylusSupremacy.insertNewLineAroundBlocks": false,
"editor.codeActionsOnSave": {
"source.fixAll.eslint": true
},
"terminal.integrated.shell.windows": "C:\\Windows\\System32\\cmd.exe",
"git.autofetch": true,
"editor.quickSuggestions": null,
"kite.showWelcomeNotificationOnStartup": false,
"workbench.editor.untitled.hint": "hidden"
}
????在vscode中Vetur也有一套Format规则,因此会和prettier冲突,找到Vetur的Format将Vetur改成Prettier就好了
husky lint-staged安装
npm i -D husky lint-staged
husky lint-staged配置
????配置git commit校验,打开package.json,添加如下代码
"scripts": {
"lint-staged": "lint-staged"
},
"husky": {
"hooks": {
"pre-commit": "npm run lint-staged"
}
},
"lint-staged": {
"**/*.js": "eslint --ext .js",
"**/*.vue": "eslint --ext .vue",
"src/**/*.scss": "stylelint --syntax scss && stylelint --fix scss"
},
????注意在husky高版本中弃用了此配置方法。此处husky:1.2.2,lint-staged: ^10.5.3
