lerna管理本地（自定义）模块依赖

工程步骤

初始化lerna项目，修改配置文件，加入快捷命令

lerna init

# \lerna.json
{
    "packages": [
        "apps/app",
        "modules/module"
    ],
    "version": "1.0.0"
}

# \package.json
{
  "name": "lernatest",
  "version": "1.0.0",
  "description": "",
  "scripts": {
        "prebuild": "npm install && lerna bootstrap",
        "build:dev": "npm run build",
        "build": "lerna run build --stream",
        "clean": "lerna run clean --stream",
        "clean-all": "npm run remove-package-lock && npm run remove-maven-folders && npm run remove-node-modules",
        "remove-node-modules": "npx lerna exec -- rm -rf node_modules && rm -rf node_modules",
        "remove-package-lock": "npx lerna exec -- rm -rf package-lock.json && rm -rf package-lock.json",
  },
  "author": "",
}

在\modules\module\目录执行

npm init -y

加入moment依赖后得到的文件

# \modules\module\package.json
{
  "name": "module",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "moment": "^2.27.0"
  }
}

# modules\module\index.js
const moment= require('moment') 

 function fmtTime(ymd){
    console.log(moment(ymd).format("YYYY-MM-DD"))
}

const API = 'http://test.com/mock/api/test';

module.exports = {
  API,
  fmtTime
}

在\apps\app\目录执行

npm init -y

# apps\app\package.json
{
  "name": "app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "babel-node index.js "
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "axios": "^0.19.2",
    "module": "^1.0.0"
  },
  "devDependencies": {
    "babel-core": "^6.26.3",
    "babel-preset-env": "^1.7.0"
  }
}

上面的package.json中对module的依赖可以通过在\目录下执行以下命令加入， 外部库依赖也可以使用该命令

lerna add module --scope=app

# apps\app\index.js
import   M from 'module'
import axios from 'axios'

const api=M.API

const fmtTime=M.fmtTime

const request = () => axios.get(api)
 
request().then((res) => console.log(res.data.data[0]));
fmtTime('20200628')

# apps\app\.babelrc
{                
    "presets": [ 
         "env"   
     ],          
    "plugins": []
}   

在\目录进行编译(如果有编译步骤)

lerna run build

在\apps\app目录执行

npm run start

每次依赖改动后要执行

lerna bootstrap
