What is Monorepo

In fact, it is very simple. It means that a code base contains many projects. Although these projects are related, they are logically independent and can be worked on by different people or teams. Maintenance

Why use pnpm

For Monorepo projects, it is very convenient to use pnpm for package management. Because there may be multiple packages for the component library we are about to develop, and these packages need to be tested in conjunction with each other locally, so pnpm has natural support for them. In fact, other package management tools, such as yarn, lerna, etc., can also do it, but it is relatively cumbersome. pnpm is now very mature. Star component libraries such as Vant and ElementUI are using pnpm, so this project also uses pnpm as a package management tool.

Use of pnpm

Installation

npm install pnpm -g

Copy after login

Initialize the project

Execute pnpm init in the project root directory, it will be automatically generatedpackage.jsonFile

{
  "name": "easyest",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

Copy after login

Package Management

We create a new packages folder for subsequent storage of our various packages. If we have package a and package b, create a and b under packages (used here to test the local reference of pnpm), and then execute pnpm initInitialization

# in the a and b directories respectively. ##You need to change the package name here. I changed the name here to @easyest/a to indicate that this a package belongs to the easyest organization. Before publishing, make sure you are logged into npm and create an organization, such as easyest. For example, the package.json of a at this time

{
  "name": "@easyest/a",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

Copy after login

Here our a package represents the tool package, and the main attribute of package.json is the entrance of the package, which is index.js.

So create a new index.js in the a directory

export default () => {
  console.log("我是@easyest/a包");
};

Copy after login

Then create a new index.js in the b package for reference

import sayHello from "@easyest/a";
sayHello();

Copy after login

p> ;We use the a package, so we need to install a first, and execute

pnpm add @easyest/a in the B directory. Obviously, this will cause an error, because we have not associated the two packages, so how to proceed? The association is actually very simple.

Create a new pnpm workspace file pnpm-workspace.yaml in the root directory to associate the packages.

packages:
    - &#39;packages/**&#39;

Copy after login

This means that all packages in the packages directory are Associate, and then execute

pnpm add @easyest/a

Note that we use import es6 syntax here, so we need to add # between A and B New field in ##package.json

"type": "module"We will find that the soft link of a appears directly in the node_modules of the b directory. At the same time, b's package.json has more dependency fields

"@easyest/a": "workspace:^1.0.0"

, which means it has been associated with the local @easyest/aPackage

How to build Monorepo project component library in Vue3 At this time we execute in the b directory

node index.js

How to build Monorepo project component library in Vue3 At this time we have completed the local package association, it will become more convenient to test the package in the future
