This article does not focus on YARN. Instead, it lists common project commands for quick use in projects. You can find more principles in another document

Create a new project

yarn init
Copy the code

And then a hint

Name (your-project): version (1.0.0): description: Entry point (index.js): Git repository: Author: License (MIT):Copy the code

Generate package.json file

{
  "name": "my-new-project"."version": "1.0.0"."description": "My New Project description."."main": "index.js"."repository": {
    "url": "https://example.com/your-username/my-new-project"."type": "git"
  },
  "author": "Your Name <[email protected]>"."license": "MIT"
}
Copy the code


Add, update, and delete dependencies

Yarn/yarn install One-click jpackage.json All packages YARN add [package] - If you add a package, the latest version is automatically installed, and the specified version is overwritten!! Yarn add [package]@[version] - Install the version yarn Remove [Package] Remove a package YARN Upgrade [package] Update a package yarn add vue Install a package yarn Add [email protected] Install a package yarn Upgrade vue Update a package yarn Upgrade [email protected] Update a package of a certain version yarn Remove vue yarn add vue Install dependencies yarn add vue --save-dev install devDependenciesCopy the code


NPM and YARN are compared

npm install [package] –save / -S yarn add [package] Installed to the dependencies
npm install [package] –save-dev/ -D yarn add [package] –save-dev Installed to the devDependencies
NPM I [package]@[version number] Yarn add [package]@[version number] Specify the version number to download the update
npm install [package] –global yarn global add [package] Install a package globally
npm update –global yarn updade upgrade Update all packages
npm uninstall [package] yarn remove [package] Deleting a package


Mind maps are easy to remember
