Getting Started Guide for Each Package Manager

Before we compare, let’s take a quick look at how to use each package manager.

1. npm – the classic choice

npm (Node Package Manager) comes bundled with Node.js and is the first choice for many developers.

Installation

npm is usually installed automatically when installing Node.js. You can check by running the following command:

<code>npm -v</code>

If it is not installed, please download it from the Node.js official website.

Common commands

• Initialization project:

<code>  npm init -y</code>

• Installation package:

<code>  npm install <package-name></code>

• Global installation:

<code>  npm install -g <package-name></code>

• Run the script:

<code>  npm run </code>

2. Yarn – King of Speed

Yarn was launched by Facebook to make up for the shortcomings of npm, focusing on speed and reliability. ?️

Installation

Install Yarn globally:

<code>npm install -g yarn</code>

Check version:

<code>yarn -v</code>

Common commands

• Initialization project:

<code>yarn init -y</code>

• Installation package:

<code>yarn add <package-name></code>

• Global installation:

<code>yarn global add <package-name></code>

• Run the script:

<code>yarn </code>

3. pnpm – a space-saving tool

If disk space is limited, pnpm (high performance npm) is your ideal choice. It's fast, efficient and lightweight. ?

Installation

Install pnpm globally:

<code>npm install -g pnpm</code>

Check version:

<code>pnpm -v</code>

Common commands

• Initialization project:

<code>  pnpm init</code>

• Installation package:

<code>  pnpm add <package-name></code>
