yarn workspace

yarn 版本

version:1.22.4
可使用npm i yarn -g 升级或安装
Upgrading Yarn itself：yarn set version latest

创建一个项目作为根项目

#zsh
mkdir yarn-workspace-test
cd yarn-workspace-test
yarn init -y

创建两个package

mkdir packages && cd packages
mkdir common
mkdir server
cd common
yarn init -y
cd ../server
yarn init -y

修改根项目的package.json

{
....
    "private": true,
     "workspaces": [
        "packages/*"
    ],
 ...
}

实现server包中引用common中的模块

cd packages/common
touch index.js
cd ../server
touch index.js

common/index.js

 module.exports = ( ) => console.log('This is a function in common');

server/index.js

 const func = require('common');
func()

安装依赖并运行

yarn install
node packages/server/index.js

看到输出:This is a function in common

在server或common下安装依赖

common和server目录下，没有node_modules目录，依赖安装到了跟项目的node_modules下

cd packages/server
yarn add jest
ls

未发现node_modules
