NodeJS Yarn Package Manager

Creating a basic package

The yarn init command will walk you through the creation of a package.json file to configure some information about your package. This is similar to the npm init command in npm.

Create and navigate to a new directory to hold your package, and then run yarn init

mkdir my-package && cd my-package
yarn init

Answer the questions that follow in the CLI

question name (my-package): my-package
question version (1.0.0):
question description: A test package
question entry point (index.js):
question repository url:
question author: StackOverflow Documentation
question license (MIT):
success Saved package.json
 Done in 27.31s.

This will generate a package.json file similar to the following

 "name": "my-package",
 "version": "1.0.0",
 "description": "A test package",
 "main": "index.js",
 "author": "StackOverflow Documentation",
 "license": "MIT"

Now lets try adding a dependency. The basic syntax for this is yarn add [package-name]

Run the following to install ExpressJS

yarn add express

This will add a dependencies section to your package.json, and add ExpressJS

"dependencies": {
 "express": "^4.15.2"
