Key Highlights Of This Node.js Course
What You Will Learn
Installation of Node.js
Begin your Node.js journey by understanding its purpose and how it differs from traditional client-side JavaScript. You’ll also learn how to set up your development environment across various operating systems to ensure a smooth start.
Topics Covered:
- Overview
Get an introduction to the course structure and what to expect as a learner. You’ll understand the significance of Node.js in today’s development landscape and how it powers scalable, server-side applications. - What is Node.js?
Explore the fundamental definition of Node.js as a runtime environment built on Chrome’s V8 engine. Learn how it executes JavaScript code outside the browser, and understand its event-driven, non-blocking nature that makes it ideal for I/O-heavy applications. - Environment Setup: Windows
Follow a guided walkthrough for installing Node.js on a Windows machine. You’ll learn how to download the installer, verify your installation using the command line, and configure your development environment. - Environment Setup: macOS
Learn how to install Node.js on macOS using Homebrew or Node Version Manager (nvm). This section will help Mac users manage multiple Node versions easily and ensure their setup is development-ready.
- Environment Setup: Linux
Understand how to install Node.js on Linux systems using package managers like APT (Debian/Ubuntu) or YUM (RHEL/CentOS). You’ll also explore environment variables and permissions required for smooth operation.
Core Concepts
Delve into Node.js architecture and its unique approach to handling concurrent operations. This section helps you grasp how Node.js handles multiple client requests efficiently using an event-driven, single-threaded model.
Topics Covered:
- Overview
Build foundational knowledge about Node.js internals. You’ll understand its position in the tech stack, how it runs, and its advantages over traditional server-side languages like PHP or Ruby. - LREPL
Learn how to use the Node.js REPL (Read-Eval-Print Loop), a command-line interface where you can test, experiment with, and debug JavaScript code interactively in real time. - REPL Alternatives
Discover more flexible and powerful alternatives to the built-in REPL, including cloud-based editors, browser-based Node environments, and integrated terminal tools within code editors like VS Code. - JS: Runtime Environment
Explore how Node.js acts as a runtime that allows JavaScript to run outside the browser. You’ll understand how Node integrates with system-level APIs to perform file operations, networking, and more.
- I/O Model
Learn about Node’s non-blocking I/O model and event loop mechanism. You’ll see how this model enables Node.js to handle thousands of simultaneous operations without multi-threading, making it ideal for scalable applications.
Modules & Packages
Understand how to structure your Node.js applications using modules and packages. Learn how to manage dependencies, automate tasks, and reuse code efficiently with built-in and third-party tools.
Topics Covered:
- Overview
Get a comprehensive introduction to the modular architecture in Node.js. Learn how modules keep your code organized and maintainable and how packages make it extensible. - Node Package
Learn how to create and configure a package.json file to define your project’s metadata and dependencies. Understand the role of npm (Node Package Manager) in handling these packages. - Third-Party Package
Understand how to install and integrate third-party packages from npm into your projects. You’ll explore package versioning, semantic versioning rules, and how to keep dependencies secure and up to date. - Custom Script in Node Package
Learn to automate common tasks like starting your server or running build scripts using custom npm commands. You’ll write custom scripts in your package.json to improve workflow efficiency.
- Types of Modules/Packages
Explore the three primary module types in Node.js—core (built-in) modules, local modules, and external packages. You’ll understand when and how to use each type to create modular, maintainable applications.
