Course Outline

1. Introduction to Node.js

• Node.js Architecture:
  Dive into Node.js’s core architecture — its single-threaded event loop, non-blocking I/O, and the role of the V8 engine.
• How Node.js Works:
  Grasp the key principles behind Node.js, such as event-driven programming and the use of callbacks and promises.
• Installing Node.js:
  Learn to install Node.js on your machine, set up the environment, and verify the install.

2. Getting Started with Node.js

• Your First Node App:
  Create your first “Hello, World!” app to see how Node.js executes and outputs.
• Globals in Node.js:
  Explore global objects and variables available in Node.js, such as global, process, and require.

3. Modules in Node.js

• Modules in Node.js:
  Understand the module concept in Node.js, including CommonJS and ES6 module systems.
• Creating a Module in Node.js:
  Learn to build custom modules and organize your code cleanly.
• Loading (Requiring) a Module in Node.js:
  Discover how to import and use modules in your Node.js apps.
• The Module Wrapper Function:
  Dive into how the module wrapper works under the hood and how it encapsulates your code.

4. Built-in Modules

• The Path Module in Node.js:
  Work with file paths and directories using the path module.
• The OS Module in Node.js:
  Interact with operating-system details and utilities using the os module.

5. Events and the Event Emitter

• Events and Event Emitter in Node.js:
  Understand Node.js’s event-driven nature and how to use the EventEmitter class to handle events.
• Event Arguments:
  Learn how to pass and handle arguments when emitting and listening for events.

6. The HTTP Module

• The HTTP Module in Node.js:
  Build simple HTTP servers and clients with the built-in http module. Handle requests and responses to create basic APIs.
