一.初始化项目
npm init vite
然后会出现请输入项目名称: 输入你的项目名称
然后选择vue
然后选择vue-ts, 根据你的项目是否需要ts
然后就生成了模板文件
二. 打开项目
# npm
npm install eslint --save-dev
# yarn
yarn add eslint --dev
# npm
npx eslint --init
# yarn
yarn run eslint --init
# 选择 帮我们找到不规范的语法,并且强制应用代码规范 选第三个

Checking peerDependencies of eslint-config-standard@latest
The config that you've selected requires the following dependencies:
eslint-plugin-vue@latest @typescript-eslint/eslint-plugin@latest eslint-config-standard@latest eslint@^8.0.1 eslint-plugin-import@^2.25.2 eslint-plugin-n@^15.0.0 eslint-plugin-promise@^6.0.0 @typescript-eslint/parser@latest
# 选择 yes 安装依赖
? Would you like to install them now? » No / Yes
# 选择你的安装方式 npm
? Which package manager do you want to use? ...
> npm
yarn
pnpm
在.eslintrc.cjs 文件中添加rules规则
module.exports = {
env: {
browser: true,
es2021: true
},
extends: [
'plugin:vue/vue3-essential',
'standard'
],
parserOptions: {
ecmaVersion: 'latest',
parser: '@typescript-eslint/parser',
sourceType: 'module'
},
plugins: [
'vue',
'@typescript-eslint'
],
rules: {
// 禁止出现console
'no-console': 'warn',
// 禁用debugger
'no-debugger': 'error'
}
}
此时eslint配置的规则已经生效
设置eslint忽略文件
在根目录创建.eslintignore 文件
添加要忽略的文件
# eslint 忽略检查 (根据项目需要自行添加)
node_modules
dist
添加vscode保存自动解决eslint报错问题
打开vscode设置
在 setting.json 添加一下配置
{
"eslint.format.enable": true,
"eslint.alwaysShowStatus": true,
// 保存自动解决eslint报错
"editor.codeActionsOnSave": {
"source.fixAll": true,
"eslint.autoFixOnSave" : false,
},
}
添加提交代码校验代码规范
安装 lint-staged mrm
// 安装完成会自动生成 .husky 文件夹
npx husky install
npx mrm@2 lint-staged
配置 git commit hook:
在package.json添加以下内容
// eslint 需要验证 src目录下所有的 js、jsx、vue、ts、tsx 后缀的文件资源,对他们进行代码规范验证
// --fix 是指对于不符合要求的代码会自动格式化(简单的自动优化)
// "git add" 自动修复eslint错误后自动提交
{
"scripts": {
"lint": "eslint src/**/*.{js,jsx,vue,ts,tsx} --fix",
"prepare": "husky install"
},
"devDependencies": {
"husky": "^8.0.1",
"lint-staged": "^12.3.5",
},
"lint-staged": {
"src/**/*.{js,jsx,vue,ts,tsx}": [
"eslint --fix",
"git add"
]
}
}
如果安装失败 删掉node_modules文件重新安装
快速删除node_nodules
安装npm install rimraf -g
控制台输入rimraf node_modules
执行完之后根目录就会出现 .husky
文件夹, 修改pre-commit 文件里面的代码为
#!/bin/sh
. "$(dirname "$0")/_/husky.sh"
npx lint-staged
可以尝试输入错误让eslint检验,再来commit 测试
最后就大功告成了!!!
