Next.js - The Comprehensive Guide

Who it's for

  • Experienced TypeScript and JavaScript developers
  • Engineers moving from Java, C#, Python or Go
  • CTOs and tech leads evaluating AI integration

You build a real app, not toy examples

Every concept is applied to one cohesive project: HelpDesk AI, an AI-powered support portal. You build it end to end, not as a pile of disconnected snippets.

What's inside

  1. 1TypeScript, modern JavaScript and React, from fundamentals to advanced patterns
  2. 2Next.js: routing, rendering strategies, data fetching and styling
  3. 3Databases with Prisma, authentication, forms, email and real-time
  4. 4The Vercel AI SDK: chat, structured output, tool calling and RAG with pgvector
  5. 5Testing, security, monitoring and deployment to Vercel and Docker
  6. 6Internationalisation, the ecosystem and AI-assisted development with Claude Code

Why I'm writing it

I'm Florian Wessels, and I build AI-powered web apps for a living. I wanted the book I wish I'd had: one cohesive, production-grade project instead of disconnected tutorials. The same expertise goes into the apps I build for clients.
