Course 1

Next.js API Routes: The First Step

3 lessons

12 practices

Get started with backend development in Next.js! You'll learn to create your first API endpoints, handle web requests, and serve JSON data, testing your work with the powerful curl command-line tool.

Course 2

Handling Data with POST, PUT, PATCH and DELETE

4 lessons

16 practices

Expand your API's capabilities by learning to create, update, and delete data. You'll implement handlers for POST, PUT, PATCH and DELETE requests, work with request bodies, and build dynamic routes to manage individual resources.

Course 3

Building Robust and Modular APIs

4 lessons

14 practices

Take your API to the next level by making it more robust and maintainable. You'll learn to validate incoming data, create centralized error responses and success messages, and use middleware to log requests in a structured and insightful way. You'll also refactor core logic into reusable service modules—key skills for building professional-grade applications.

Course 4

Project: Building a Task Manager API

4 lessons

16 practices

Build a fully functional backend API for managing tasks, applying robust architecture patterns such as centralized response utilities, a dedicated service layer, and secured access via API key middleware. The project culminates in connecting the backend with a user interface to observe real-time API behavior.

Course 5

Refactoring for Production Readiness

3 lessons

11 practices

This course strengthens learners' backend development skills by introducing production-grade practices. It focuses on replacing in-memory logic with persistent storage, enforcing professional validation standards, and abstracting data access into repositories. By simulating real-world persistence and layering, learners prepare for transition into full-stack or database-backed applications.
