Installation Guide

Installing Node.js on Ubuntu/Debian-based Systems

### Update package list
sudo apt-get update

### Install required dependencies
sudo apt-get install -y build-essential zlib1g-dev libssl-dev libcrypto++-dev

### Download and install Node.js from the official repository
wget https://deb.nodesource.com/setup_16.x | sudo bash -
sudo apt-get install nodejs

Installing Node.js on macOS High Sierra (64-bit)

### Install Homebrew if not already installed
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

### Install required dependencies
brew install readline openssl

### Download and install Node.js using the official repository
wget https://deb.nodesource.com/setup_16.x | sudo bash -
sudo apt-get install nodejs

Common Installation Issues and Solutions

• Error: unable to find package 'openssl'
  • Solution: Run brew install readline openssl on macOS High Sierra or apt-get install -y build-essential zlib1g-dev libssl-dev libcrypto++-dev on Ubuntu/Debian-based systems.
• Error: installation failed due to conflicts with other packages
  • Solution: Try upgrading the conflicting package using sudo apt-get update && sudo apt-get dist-upgrade or brew upgrade on macOS High Sierra.

Post-Installation Configuration

After installing Node.js, you may need to configure the following files:

• /etc/nodejs/config.json: This file stores the default configuration settings for Node.js. You can edit this file using a text editor.
• .nodeversionrc: This file specifies the version of Node.js to use on your system.

Technical Architecture

Node.js is built on top of the Chrome V8 JavaScript engine, which provides unparalleled performance and scalability. The core technologies used by Node.js include:

• JavaScript: Node.js executes JavaScript code using the V8 engine.
• Event-Driven I/O: Node.js uses an event-driven I/O model to handle concurrent connections and requests.
• Libuv: Node.js uses Libuv, a lightweight library for handling asynchronous I/O operations.

Node.js connects to various services and databases through APIs or network sockets. Some of these connections include:

• HTTP: Node.js can serve HTTP requests using the built-in http module.
• TCP: Node.js can establish TCP connections using the net module.
• MySQL: Node.js can connect to MySQL databases using the mysql package.

Performance Considerations

Node.js is optimized for high-performance and scalability, but it requires careful tuning of the following performance considerations:

• Concurrency: Node.js can handle multiple concurrent requests efficiently, making it a good choice for real-time web applications.
• Memory Usage: Node.js has a relatively low memory footprint compared to other JavaScript runtimes, making it suitable for resource-constrained environments.

Dependencies

Node.js relies on the following libraries and frameworks:

Note: The version numbers listed above are examples and may change over time.

By following this documentation, you should be able to successfully install and configure Node.js on your system, as well as understand its technical architecture and performance considerations.
