Node.js Requirements

Before developing with Node.js, it is important to understand the system and environment requirements. These ensure a smooth installation, setup, and development experience across different operating systems.

1. System Requirements

Node.js is lightweight and can run on various hardware setups. However, here are the minimum and recommended system specifications:

Minimum Requirements:

• CPU: 1 GHz or faster
• RAM: 512 MB
• Storage: At least 200 MB free space
• Operating System: Windows 7+, macOS 10.10+, Linux Kernel 2.6.18+

Recommended for Development:

• CPU: Dual-core or higher
• RAM: 2 GB or more
• Storage: SSD recommended for faster npm install
• Operating System: Latest version of Windows/macOS/Linux

Explanation: While Node.js can run on low-end systems, development tasks (like installing packages, compiling tools, and running dev servers) are much faster with more RAM and SSD storage.

2. Software Requirements

Before you start developing with Node.js, you’ll need the following software installed:

a. Node.js Runtime

• Install the latest LTS version from the official site: https://nodejs.org

b. npm (Node Package Manager)

• Comes bundled with Node.js.
• Used to install libraries and frameworks such as Express, Mongoose, etc.

Check installation:

c. Code Editor Choose a reliable editor for writing Node.js applications:

• Visual Studio Code (Recommended)
• Sublime Text
• Atom
• WebStorm

Explanation: VS Code offers integrated terminal, Git support, debugging, and Node.js extensions.

3. Environment Setup (Optional but Useful)

a. Git

• Version control system.
• Install from: https://git-scm.com

b. Postman or API Testing Tool

• Used to test HTTP APIs created with Node.js and Express.
• Download from: https://www.postman.com

c. MongoDB (For Full-stack Projects)

• Install MongoDB if you plan to build backend apps that use a database.
• Website: https://www.mongodb.com/try/download/community

4. Node.js Supported Platforms

Node.js runs on:

• Windows (x86 and x64)
• macOS
• Linux (Ubuntu, Debian, Fedora, CentOS)
• ARM devices (like Raspberry Pi)

Explanation: Node.js is portable and performs well across all platforms, making it a good choice for cross-platform development.
