Course Overview

Build Production-Ready Fullstack Apps with Next.js 15

Next.js 15 is the framework behind some of the most visited sites on the web, combining React's component model with server-side rendering, the App Router, and a built-in backend layer — all in one TypeScript-first codebase. This track teaches you to build complete, deployable fullstack applications: from routing and data fetching through database integration, authentication, and production deployment.

What You Will Learn

You will start with the Next.js 15 core — file-based routing, server and client components, and the App Router. From there you will handle data fetching patterns, build polished UIs, and manage forms and user input. On the backend side you will integrate databases with Prisma, design API routes, and implement authentication and authorization. The advanced courses cover state management and caching strategies, testing methodologies, and performance optimization techniques required for real production workloads.

The Learning Path

Twelve courses span A1 through C1. The track opens with Next.js 15 Core Fundamentals and React Foundations for Next.js to establish a solid base, then works through B1 and B2 topics including Database Integration with Prisma, Advanced Routing and Layout Patterns, and Authentication and Authorization. The final three C1 courses — Advanced State Management & Caching, Deployment and Performance Optimization, and Testing and Advanced Fullstack Patterns — bring you to a professional level across the full stack.

How It Works

Each course is split into short, hands-on lessons you complete in the built-in code editor with real-time feedback. An AI tutor is available whenever you get stuck, and the progression is structured so each concept builds directly on the one before it.
