Introduction to how the Web works and Rest APIs3:18
Discover how the web operates via a client-server model and how node.js enables tooling sharing, with http and rest guiding application programming interface design through endpoints, methods, and data formats.
Working with the HTTP module9:13
Set up a Node.js API project with npm init and nodemon, then build an http server using the core http module, listen on port 3000, and respond to client requests.
Understanding Web Headers12:15
Explore how http request and response headers control data in a nodejs api, including content-type and status codes like 200, and learn practical header manipulation.
Handling Get Requests7:43
Learn to handle get requests in a native node.js API by listening for request events with on, checking req.method, and returning a hello message or 405 method not allowed.
Returning JSON responses and handling URLs9:25
Implement a /products route that returns a json array of products with name properties, stringify it, set content type to application/json, and provide 404 handling for other paths.
Handling POSTs Requests8:20
Explore handling post requests in a native nodejs api by serving an html form at the root route to add new products to a list, and processing posts to /products.
Parsing Request Body Data11:05
Learn to parse urlencoded request bodies in a native Node.js API by building a promise-based parse function that extracts product names and updates the products array on post requests.
Adding a Middleware and sharing data in the request11:05
Implement middleware to inspect incoming requests, log method and url, and share data via the rack object for error handling and validation in a native node.js api.

Requirements

Basic understanding of JavaScript fundamentals (variables, functions, objects, and basic logic).
A computer (Windows, macOS, or Linux) and a modern code editor like VS Code installed.
No prior back-end or framework experience is required. We start from the absolute ground up!

Description

"“This course contains the use of artificial intelligence"

Before you can architect robust starter templates or scalable SaaS platforms, you need to understand exactly what happens under the hood. While frameworks like Express and Fastify are great for speed, relying on them without understanding native web mechanics leaves gaps in your back-end knowledge.

In this focused, hands-on course, we strip away the magic. You will learn how to build a fully functional REST API using only the native capabilities of Node.js. By the end of this course, you will have a profound understanding of how the web actually works, making you a much stronger, more versatile developer.

What You Will Learn:

The Foundations of Web Mechanics: Understand the architecture of the web and the principles of REST APIs.
The Native HTTP Module: Master Node.js's built-in HTTP module to create servers and handle network traffic directly.
Header & Protocol Mastery: Confidently read, set, and manipulate Web Headers to control how clients and servers communicate.
Routing & Methods: Manually handle GET and POST requests, parse URLs, and securely extract request body data.
Custom Middleware: Build your own middleware functions from scratch to process and share data efficiently across your application.

Who This Course is For:

Beginner to intermediate developers who want to move beyond just typing boilerplate code.
Self-taught engineers looking to solidify their understanding of back-end fundamentals.
Anyone preparing to build complex, high-performance web applications who wants to master the core technologies first.

Join today and take your first step toward mastering pure Node.js!

Who this course is for:

Self-taught developers wanting a rock-solid understanding of web mechanics before using frameworks like Express.
Front-end engineers looking to transition to the back-end by mastering the native HTTP request and response cycle.
Anyone preparing to architect complex backend systems who wants to thoroughly understand the core technologies first.
