lerna-demo

lerna分包管理npm插件

前提：确认当前是否登录npm

npm发布的时候会验证用户，为了保证发布流程通畅

# 登录npm
$ npm whoami
zhengloong #说明已经登录npm账号zhengloong

#没有则登录 
$ npm login 
# 输入username password 
Logged in as zhengloong on https://registry.npmjs.org/.

一、初始化lerna框架

# 全局安装lerna（如果已安装可忽略）
$ npm install lerna -g

# 默认初始化lerna框架
$ lerna init 

二、创建npm包文件

# 在packages下创建文件夹daybyday
$ cd packages
$ mkdir daybyday

# 进入文件夹初始包
$ cd daybyday
$ npm init

项目结构(输入指令tree /f查看目录结构)：

PS G:\lerna\lerna-demo> tree /f
G:.
│  lerna.json
│  package.json
│
└─packages
    └─daybyday
            package.json

三、yarn的workspaces模式

lerna默认是npm，而且每个子package都有自己的node_modules, 通过这样的设置后，只有顶层有一个node_modules

修改顶层package.json lerna.json

# package.json 文件加入
"private": true,
"workspaces": [
"packages/*"
],

# lerna.json 文件加入
"useWorkspaces": true,
"npmClient": "yarn",

四、配置远程代码库

# 推送代码到远程库
git init
git add README.md
git commit -m "first commit"
git remote add origin git@github.com:fisher-zwl/lerna-demo.git
git push -u origin master

五、查看当前修改package

# 列出下次发版lerna publish 要更新的包。
PS G:\lerna\lerna-demo> lerna changed
lerna notice cli v3.21.0
lerna info Assuming all packages changed
daybyday
lerna success found 1 packages ready to publish
# 俩个改过的包，下次发布publish将发布这俩个

六、发布npm

# 发布前必须把本地有修改的文件全部提交远程库
$ lerna publish

按照自己的情况设置对应的版本号

PS G:\lerna\lerna-demo> lerna publish
lerna notice cli v3.21.0
lerna info current version 0.0.5
lerna info Looking for changed packages since v0.0.5
? Select a new version (currently 0.0.5) (Use arrow keys)
> Patch (0.0.6) #默认选择这个版本
  Minor (0.1.0)
  Major (1.0.0)
  Prepatch (0.0.6-alpha.0)
  Preminor (0.1.0-alpha.0)
  Premajor (1.0.0-alpha.0)
  Custom Prerelease
  Custom Version

发布完成：

PS G:\lerna\lerna-demo> lerna publish
lerna notice cli v3.21.0
lerna info current version 0.0.5
lerna info Looking for changed packages since v0.0.5
? Select a new version (currently 0.0.5) Patch (0.0.6)
