git flow 工作流程
[*] 参考链接：
[*] 新建功能
[*]新建feature分支
git checkout -b feature/MYFEATURE
git flow feature start MYFEATURE
[*]完成新功能开发，将feature分支合并到develop分支
[*]现在已写成文件，直接执行命令 yarn feature即可
git flow feature finish MYFEATURE
[*]基于最新的develop分支，切出release分支，此版本为预发布版本，分支为版本号
git checkout -b release/1.0.0
git flow release start release/1.0.0
[*]测试无问题， 执行git flow release finish 1.0.0 ，输出提交日志，合并到develop分支和mian/master分支，输入版本信息
# -m tag提交信息
# 参数参考：https://github.com/nvie/gitflow/wiki/Command-Line-Arguments#hotfix
git flow release finish 1.0.0 -m ""
[*]在develop分支，并推送develop分支到长途
git push origin develop
[*]切换到main/master 分支, 推送到长途，推送最新的tag到长途
git push origin main
git push origin v1.0.0
[*] bug修改
[*]新增一个hotfix分支
git checkout -b hotfix/1.0.1
git flow hotfix start 1.0.1
[*]修改完成后的操作与release一样
pnpm workspace
[*]创建 pnpm-workspace.yaml 文件
touch pnpm-workspace.yaml
[*]pnpm-workspace.yaml
packages:
- 'packages/*' # 代表所有项目都放在packages文件夹之下
.npmrc
# 注释：三方依赖也有依赖，要是项目中使用了第三方的依赖，
# 要是哪天第三方卸载不在该包了，那就找不到了，称之为“幽灵依赖” ，
# 所以需要“羞耻提升”，暴露到外层中，即在根目录下的node_modules内，而非在.pnpm文件夹中。
shamefully-hoist = true
# 根目录下的node_modules里，vue安装到了与.pnpm同层级位置当中了，
# 这就是shamefully-hoist = true的效果，把vue从.pnpm内提到node_modules中，
# 并且vue的相关依赖，也拍平到了该层级文件夹中。

引入Husky规范git提交
[*]安装 husky
pnpm add husky -D -w
[*]在 package.json 中 scripts 中设置 prepare 钩子:husky install,在使用pnpm install的时间就会自动执行husky,以便于别人拉取完我们代码进行pnpm insall的时间直接进行husky install（版本8操作，版本9直接执行 init）
pnpm pkg set scripts.prepare="husky install"
或者
{
"scripts": {
"prepare": "husky install"
}
}
[*]执行install， 生成.husky文件夹
# 版本 8
npx husky install
#版本9
npx husky init
[*]添加一个 commit 钩子文件
# 版本8
npx husky add .husky/pre-commit
# 版本8 .husky/commit-msg 中添加npx --no -- commitlint --edit "$1"
npx --no -- commitlint --edit "$1"
# 版本9
echo 'npx --no -- commitlint --edit "$1"' > .husky/commit-msg
# .husky/pre-commit中写入以下命令，配合eslint使用
pnpm run lint-staged
设置eslint和prettier
eslint 设置
[*]安装依赖包
# eslint eslint依赖包
# eslint-config-standard JavaScript标准样式的ESLint可配置，基础配置,比较流行的有 airbnb、standard、prettier等
# eslint-plugin-import 支持ES6以上的导入/导出语法，并防止文件路径和导入名称拼写错误的问题
# eslint-plugin-node 为node准备的eslint规则配置
# eslint-plugin-promise es语法promise的eslint最佳配置
# eslint-plugin-vue vue项目的的配置，vue项目必须
# @typescript-eslint/parser 解析器
# @typescript-eslint/eslint-plugints语法的配置
# eslint-define-config eslint-define-config可以帮助我们做语法提示
pnpm add eslint eslint-config-standard eslint-plugin-import eslint-plugin-node eslint-plugin-promise eslint-plugin-vue @typescript-eslint/parser @typescript-eslint/eslint-plugin eslint-define-config -D -w
[*]根目录下创建.eslintrc.cjs、.eslintignore文件
// .eslinttrc.cjs
// eslint-define-config可以帮助我们做语法提示
const { defineConfig } = require('eslint-define-config')
module.exports = defineConfig({
// ESLint 一旦发现配置文件中有 "root": true，它就会停止在父级目录中寻找。
root: true,
// 解析器
parser: 'vue-eslint-parser',
parserOptions: {
// 解析器
parser: '@typescript-eslint/parser',
// js的版本

// 模块化方案
sourceType: 'module',

},
},
// 启用的规则

.eslintignore
node_modules
.vscode
.idea
dist
.eslintrc.cjs
prettier 设置
[*]安装依赖
# eslint-config-prettier&eslint-plugin-prettier用于解决eslint和prettier的冲突问题
pnpm add prettier eslint-config-prettier eslint-plugin-prettier -D -w
[*]根目录创建.prettierrc文件
{
"printWidth": 150,
"tabWidth": 2,
"useTabs": true,
"semi": false,
"singleQuote": true,
"quoteProps": "as-needed",
"jsxSingleQuote": false,
"trailingComma": "es5",
"bracketSpacing": true,
"jsxBracketSameLine": false,
"arrowParens": "always",
"rangeStart": 0,
"requirePragma": false,
"insertPragma": false,
"proseWrap": "preserve",
"htmlWhitespaceSensitivity": "css",
"vueIndentScriptAndStyle": false,
"endOfLine": "auto"
}
[*] 根目录创建.prettierignore文件用于忽略prewitter格式化
[*] 安装 VSCode 插件 Prettier - Code formatter
[*]安装该插件以实现在保存的时间自动完成格式化
[*] 在 .vscode/settings.json 中添加一下规则
{
// 保存的时候自动格式化
"editor.formatOnSave": true,
// 默认格式化工具选择prettier
"editor.defaultFormatter": "esbenp.prettier-vscode"
}
设置lint-staged
[*]提交前在pre-commit中应该做一次lint 校验，在package.json添加
{
"scripts": {
"lint:script": "eslint --ext .js,.jsx,.vue,.ts,.tsx --fix --quiet ./"
}
}
[*] 在pre-commit 中添加命令 npm lint:script
[*] 根据上面的设置是可以实现我们想要的效果的,但是我们会发现每次提交代码的时间 ESlint 或 Stylelint 都会检查所有文件,而我们必要的是只让它们检测新增的文件,因此我们可以使用lint-staged来解决这个问题
[*] 安装lint-staged
pnpm add lint-staged -D -w
[*]在package.json中添加设置,更改pre-commit的命令 pnpm run lint-staged
{
"lint-staged": {
"src/**/*.{js,jsx,ts,tsx,vue}": ["eslint --ext .js,.jsx,.vue,.ts,.tsx --fix --quiet ./"]
},
"scripts": {
"lint-staged": "lint-staged"
}
}
创建项目
创建shared
[*]shared项目用来服务其他多个web项目，提供公共方法、组件、样式等等
项目全局安装 vue
# -w的意思是，workspace-root把依赖包安装到工作目录的根路径下，
# 则根目录下会生成node_modules文件夹。可以共用，后续每个项目需要用到vue的
# 都直接从根目录node_modules里取。
pnpm add vue -w
在 packages 项目下创建 vue 项目
[*]执行创建命令，根据提示选择
pnpm create vite
[*]删除 vue @vitejs/plugin-vue vite vue-tsc typescript 等依赖，安装到全局中
# 子项目下执行
pnpm remove vue
pnpm remove @vitejs/plugin-vue vite vue-tsc typescript -D
# 根目录下执行
pnpm add @vitejs/plugin-vue vite vue-tsc typescript -D -w
[*]运行项目
# 子项目下运行
pnpm dev
设置全局指令
{
"script": {
"dev:project": "cd packages/vite-project & pnpm dev"
// pnpm -C packages/vue-config-1 & pnpm dev 亦可
}
}
引用 shared 内容
[*]加入 tsconfig.json 来设置路径
# 根目录下
pnpm add typescript -D -w
pnpm tsc --init
[*]设置
{
"compilerOptions": {
"outDir": "dist", // 输出的目录
"sourceMap": true, //采用sourcemap
"target": "es2016", // 目标语法
"module": "esnext", // 模块格式
"moduleResolution": "node", // 模块解析
"strict": false, // 严格模式
"resolveJsonModule": true, // 解析json模块
"esModuleInterop": true, // 允许通过es6语法引入commonjs模块
"jsx": "preserve", // jsx不转义

"@monorepo/shared/styles": ["packages/shared/styles"],
// 或者用*号处理匹配
"@monorepo/shared/*": ["packages/shared/*"]
}
}
}
建立关联
# 指定版本号
pnpm add @monorepo/shared@workspace --filter @monorepo/vite-project
打包插件
[*]安装 minimist esbuild
pnpm add minimist esbuild -D -w
[*]新增 打包脚本
// minimist 可以解析命令行参数，非常好用，功能简单
import minimist from 'minimist'
// 打包模块
import { build } from 'esbuild'
// node 中的内置模块
import path from 'path'
import fs from 'fs'
const __dirname = path.resolve()
const args = minimist(process.argv.slice(2))

const packageName = pkaOps.buildOptions?.name
build({

bundle: true,
sourcemap: true,
format: outputFormat,
globalName: packageName,
platform: format === 'cjs' ? 'node' : 'browser',
}).then(() => {
console.log('watching~~~')
})
[*]设置 plugins package.json
{
"name": "@monorepo/common",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {

[*]设置并执行打包命令
{

}
pnpm dev:common
[*]测试使用
