pnpm+reactcreateapp 踩坑记录

一、创建项目

pnpm-workspace.yaml

packages:
  - 'packages/*'

　　

package.json

{
  "name": "pnpm-build",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "preinstall": "node ./scripts/preinstall.js",
   
    "start:app": "pnpm --filter @web/my-app  run start "
  },
  "keywords": [],
  "author": "",
  "license": "ISC",

  "engines": {
    "node": ">=10",
    "pnpm": ">=3"
}
}

　　

.nvmrc

v16

　　

.npmrc

shamefully-hoist=true
strict-peer-dependencies=false

　　

scripts/preinstall.js

if (!/pnpm/.test(process.env.npm_execpath || '')) {
    console.warn(
      `\u001b[33mThis repository requires using pnpm as the package manager ` +
        ` for scripts to work properly.\u001b[39m\n`
    )
    process.exit(1)
  }
  
  

　　

二、创建 react 项目

在 packages 文件夹下执行

npx react-create-app my-app --template typescript

1、创建结束后，删除 node_module

2、cmd 进去packages 外面，执行 pnpm install 

3、执行 pnpm run start:app

三、开始踩坑

1、到目前为止，一切正常。

2、开始发挥 pnpm 的 packages 优势，提取公共代码

3、在 packages 下面新建一个 utils 文件夹，新建 package.json

{

"name": "@web/utils"

}

4、并新建 index.ts，随便写点内容

5、在 my-app 项目中要引入 utils 里面的代码，需要在外部执行

pnpm --filter @web/my-app i @web/utils -r

　　

6、引入代码 

import {loadScript} from  "@web/utils"

　　

7、开始报错

四、解决报错

参考：https://github.com/facebook/create-react-app/issues/1333

1、先 npm run eject

2、config/paths.js 后面加入

module.exports.appPackages = []
// 注意这里 @web 是你当前 package 的前缀
const folderLernaPackageName = '@web' // this is the name of your packages folder in package.json. For example: name: '@my-monorepo/utils'
const lernaRoot = path.resolve(module.exports.appPath, '../../')
const lernaPackages = path.join(lernaRoot, 'packages') // this is the name of your packages folder in monorepo

const regexpFolderLernaPackage = new RegExp(`^${folderLernaPackageName}\\/`, 'g')
const lernaPackagesFromDependencies = Object.keys(
  require(resolveApp('package.json')).dependencies
)
  .filter((packageName) => packageName.startsWith(folderLernaPackageName))
  .map((packageName) => packageName.replace(regexpFolderLernaPackage, ''))

fs.readdirSync(lernaPackages).forEach((folderName) => {
  const isDependencyNeed = lernaPackagesFromDependencies.includes(folderName)

  if (isDependencyNeed) {
    module.exports.appPackages.push(path.join(lernaPackages, folderName))
  }
});
module.exports.appPackages.push(module.exports.appSrc)

　　

3、config/webpack.config.js
