Monorepo pnpm 模式管理多个 web 项目

项目地址

• Vue: Monorepo pnpm 模式管理多个 web 项目（Vue3)
• Nuxt:Monorepo pnpm 模式管理多个 web 项目（Nuxt)

git flow 工作流程

• 参考链接：[https://danielkummer.github.io/git-flow-cheatsheet/index.zh_CN.html]

• 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分支到远程

  git push origin develop
  

  • 切换到main/master 分支, 推送到远程，推送最新的tag到远程

  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。

• filter-flow-hotfix-finish-tag-message.sh,filter-flow-release-finish-tag-message.sh

  • git flow 工作流钩子，用于release，hotfix 打版，自定义两个命令增加中途写入CHANGELOG的功能
  • 执行git flow release finish 和 git flow hotfix finish 工作流时，会执行hooks中的filter-flow-hotfix-finish-tag-message.sh,filter-flow-release-finish-tag-message.sh
  • 具体参考：https://github.com/jaspernbrouwer/git-flow-hooks/blob/master/filter-flow-hotfix-finish-tag-message

• filter-flow-hotfix-finish-tag-message.sh, filter-flow-release-finish-tag-message.sh

• 为保证CHANGELOG正常写入，release的命名格式为xxx-tagname，tagname和提交时的scope保持一致

• 配置commit规范以及自动生成CHNAGELOG并自定义需要的依赖包

# conventional-changelog-cli 要配合conventional-changelog-custom-config使用，指定版本为@^2
# conventional-changelog-custom-config参考：https://itxiaohao.github.io/passages/git-commit/#%E6%B7%B1%E5%85%A5-conventional-changelog-%E6%BA%90%E7%A0%81
# lerna 要配合 cz-lerna-changelog 使用，指定版本为@^3.22.1
#  cz-lerna-changelog参考：https://www.npmjs.com/package/cz-lerna-changelog# -w 有工作区的时候使用
pnpm add @commitlint/cli @commitlint/config-conventional commitizen conventional-changelog-cli@^2.2.2 conventional-changelog-custom-config cz-lerna-changelog lerna@^3.22.1 -D -wpnpm add cross-env -w

• 添加comitizen相应配置，创建commitlint.config.js

touch commitlint.config.js

const fs = require('fs')
const path = require('path')module.exports = {extends: ['monorepo'],rules: {'header-max-length': [0, 'always'],// scope 不允许为空，保证CHANGELOG正常写入，release的命名格式为xxx-tagname，tagname和scope保持一致'scope-empty': [2, 'never'],'scope-enum': [2, 'always', [...fs.readdirSync(path.join(__dirname, 'packages')), 'mono']],'type-enum': [2, 'always', ['build', 'ci', 'chore', 'feat', 'fix', 'refactor', 'style', 'test', 'config', 'docs']],'close-issue-needed': [2, 'always'],},plugins: [{rules: {'close-issue-needed': (msg) => {const ISSUES_CLOSED = 'ISSUES CLOSED:'return [msg.raw.includes(ISSUES_CLOSED), 'Your commit message must contain ISSUES message']},},},],
}

• 自定定义CHANGELOG配置 changelog-option.cjs

const path = require('path')
const compareFunc = require('compare-func')// 自定义配置
let pkgJson = {}
try {pkgJson = require(path.join(__dirname, '../../package.json'))
} catch (err) {console.error('no root package.json found')
}const { changelog } = pkgJson
let bugsUrl = changelog ? changelog.bugsUrl || false : false
if (typeof bugsUrl !== 'string') bugsUrl = false
const authorName = changelog ? changelog.authorName || false : false
const authorEmail = changelog ? changelog.authorEmail || false : falselet gitUserInfo = ''
if (authorName && authorEmail) {gitUserInfo = 'by: **{{authorName}}** ({{authorEmail}})'
}
if (authorName && authorEmail === false) {gitUserInfo = 'by: **{{authorName}}**'
}
if (authorName === false && authorEmail) {gitUserInfo = 'by: ({{authorEmail}})'
}const getWriterOpts = () => {return {transform: (commit, context) => {let discard = trueconst issues = []commit.notes.forEach((note) => {note.title = 'BREAKING CHANGES'discard = false})if (commit.type === 'feat') {commit.type = 'Features'} else if (commit.type === 'fix') {commit.type = 'Bug Fixes'} else if (commit.type === 'perf') {commit.type = 'Performance Improvements'} else if (commit.type === 'revert') {commit.type = 'Reverts'} else if (commit.type === 'docs') {commit.type = 'Documentation'} else if (commit.type === 'style') {commit.type = 'Styles'} else if (commit.type === 'refactor') {commit.type = 'Code Refactoring'} else if (commit.type === 'test') {commit.type = 'Tests'} else if (commit.type === 'build') {commit.type = 'Build System'} else if (commit.type === 'ci') {commit.type = 'Continuous Integration'} else if (commit.type === 'chore') {commit.type = 'Chores'} else if (discard) {return}if (commit.scope === '*') {commit.scope = ''}if (typeof commit.hash === 'string') {commit.hash = commit.hash.substring(0, 7)}if (typeof commit.subject === 'string') {let url = context.repository ? `${context.host}/${context.owner}/${context.repository}` : context.repoUrlif (url) {url = `${url}/issues/`// Issue URLs.commit.subject = commit.subject.replace(/#([0-9]+)/g, (_, issue) => {issues.push(issue)return `[#${issue}](${url}${issue})`})}if (context.host) {// User URLs.commit.subject = commit.subject.replace(/\B@([a-z0-9](?:-?[a-z0-9/]){0,38})/g, (_, username) => {if (username.includes('/')) {return `@${username}`}return `[@${username}](${context.host}/${username})`})}}// remove references that already appear in the subjectcommit.references = commit.references.filter((reference) => {if (!issues.includes(reference.issue)) {return true}return false})if (bugsUrl) {commit.references = commit.references.map((ref) => {return {...ref,bugsUrl,}})}const needChangelog = commit.header.includes('(changelog-needed)') && commit.header.includes(`(${process.env.PACKAGE}):`)// 可在此过滤所需要的commit信息if (needChangelog) {commit.header = commit.header.replace(/\(changelog-needed\)/g, '')}return needChangelog ? commit : null},groupBy: 'type',commitGroupsSort: 'title',commitsSort: ['scope', 'subject'],noteGroupsSort: 'title',notesSort: compareFunc,finalizeContext: (context) => {return Object.assign(context, {version: process.env.CURRENT_TAG,linkCompare: false,})},}
}module.exports = {gitRawCommitsOpts: {from: process.env.PREVIOUS_TAG,to: process.env.CURRENT_TAG,},writerOpts: getWriterOpts(),
}

{"repository": {"type": "git","url": "https://github.com/example.git"},"changelog": {"bugsUrl": "https://github.com/","authorName": true,"authorEmail": false}
}

• 配置 cz-lerna-changlog,支持选择packages

const czLernaChangelog = require('cz-lerna-changelog')function makePrompter() {return function (cz, commit) {cz.prompt([{type: 'confirm',name: 'addChangeLog',message: 'Auto add `(changelog-needed)` to subject line?\n',},]).then((answer) => {let customQuestion = [{type: 'input',name: 'subject',message: 'Write a short, imperative tense description of the change:\n',filter: function (value) {const mark = (answer.addChangeLog && '(changelog-needed)') || ''return value.charAt(0).toLowerCase() + value.slice(1) + mark},validate: function (value) {return !!value},},]return czLernaChangelog.makePrompter(() => customQuestion)(cz, commit)})}
}module.exports = {prompter: makePrompter(),makePrompter: makePrompter,
}

{"config": {"commitizen": {"path": "./scripts/changelog/cz-lerna-changelog.cjs"}},"workspaces": ["packages/*"]
}

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的时候就会自动执行husky,以便于别人拉取完我们代码进行pnpm insall的时候直接进行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

配置eslint和prettier

eslint 配置

• 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-plugin  ts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ecmaVersion: 2020,// 模块化方案sourceType: 'module',ecmaFeatures: {jsx: true,},},// 启用的规则extends: ['plugin:vue/vue3-recommended', 'plugin:@typescript-eslint/recommended', 'standard'],rules: {quotes: ['error', 'single'],'@typescript-eslint/ban-ts-ignore': 'off','@typescript-eslint/explicit-function-return-type': 'off','@typescript-eslint/no-explicit-any': 'off','@typescript-eslint/no-var-requires': 'off','@typescript-eslint/no-empty-function': 'off','@typescript-eslint/no-use-before-define': 'off','@typescript-eslint/ban-ts-comment': 'off','@typescript-eslint/ban-types': 'off','@typescript-eslint/no-non-null-assertion': 'off','@typescript-eslint/explicit-module-boundary-types': 'off','@typescript-eslint/no-unused-vars': ['error',{argsIgnorePattern: '^h$',varsIgnorePattern: '^h$',},],'no-use-before-define': 'off','no-unused-vars': ['error',{argsIgnorePattern: '^h$',varsIgnorePattern: '^h$',},],'no-tabs': 'off',indent: 'off','vue/custom-event-name-casing': 'off','vue/html-indent': 'off','vue/max-attributes-per-line': 'off','vue/html-self-closing': 'off','vue/singleline-html-element-content-newline': 'off','vue/multi-word-component-names': 'off','space-before-function-paren': 'off','comma-dangle': 'off',},
})

.eslintignore
node_modules
.vscode
.idea
dist
.eslintrc.cjs

prettier 配置

• 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候自动完成格式化

• 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"
}

配置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

• 根据上面的配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候 ESlint 或 Stylelint 都会检查所有文件,而我们需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中添加配置,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 vuepnpm 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

配置全局指令

{"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 来配置路径

# 根目录下
pnpm add typescript -D -w
pnpm tsc --init

• 配置

{"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"lib": ["esnext", "dom"], // 支持的类库esnext及dom"baseUrl": ".", // 当前是以该路径进行查找"paths": {"@monorepo/shared/components": ["packages/shared/components"],"@monorepo/shared/utils": ["packages/shared/utils"],"@monorepo/shared/fetch": ["packages/shared/fetch"],"@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 target = args._[0]
const format = args.f || 'global'
const entry = path.resolve(__dirname, `./packages/plugins/${target}/src/index.ts`)
/*  iife 立即执行函数(function(){})()cjs node中的模块 module.exportsesm 浏览器中的esModule模块 import */
const outputFormat = format.startsWith('global') ? 'iife' : format === 'cjs' ? 'cjs' : 'esm'
const outfile = path.resolve(__dirname, `./packages/plugins/${target}/dist/${target}.${format}.js`)
const pkaPath = path.resolve(__dirname, `./packages/plugins/${target}/package.json`)
const pkaOps = JSON.parse(fs.readFileSync(pkaPath, 'utf8'))
const packageName = pkaOps.buildOptions?.name
build({entryPoints: [entry],outfile,bundle: true,sourcemap: true,format: outputFormat,globalName: packageName,platform: format === 'cjs' ? 'node' : 'browser',
}).then(() => {console.log('watching~~~')
})

• 配置 plugins package.json

{"name": "@monorepo/common","version": "1.0.0","description": "","main": "index.js","scripts": {"test": "echo \"Error: no test specified\" && exit 1"},// 打包会用到, 用于定义全局变量"buildOptions": {"name": "common"},"keywords": [],"author": "","license": "ISC","dependencies": {"@monorepo/shared": "workspace:^"}
}

• 配置并执行打包命令

{"scripts": {"dev:common": "node scripts/dev-plugins.js common -f global"}
}

pnpm dev:common

• 测试使用

<!doctype html>
<html lang="en"><head><meta charset="UTF-8" /><meta name="viewport" content="width=device-width, initial-scale=1.0" /><title>Document</title></head><body><script src="./common.global.js"></script><script>const { testFunc } = commonconsole.log(testFunc())</script></body>
</html>

配置单命令启动多项目

{"scripts": {"serve": "node ./scripts/build/build.cjs","build": "node ./scripts/build/build.cjs --production"}
}

• build.cjs

const { spawn } = require('child_process')
const core = require('./core.cjs')
const path = require('path')class BuildCore extends core {constructor(optionArray = []) {super()this.initOption(optionArray)this.start()}/*** @description 执行构建流程*/start() {this.getPackages().then(async () => {this._argument = this._program.parse(process.argv).argstry {const answer = await this.selectPackage()answer && this._argument.unshift(answer)this.initBuildSpawn()} catch (error) {console.error('the application must be selected!')}})}/*** @description 初始化本地开发或者构建build过程*/initBuildSpawn() {if (!this.validatePackage()) return falseconst isProduction = this._program.parse(process.argv).productionprocess.env.PACKAGE = this._argument[0]process.env.NODE_ENV = isProduction ?
