Build a production-ready, AI-powered Next.js application from scratch. One cohesive project, 28 chapters, zero toy demos.

Next.js: The Comprehensive Guide teaches you full-stack web development with Next.js by building HelpDesk AI, an AI-powered support portal where customers submit tickets, agents handle them with the help of an AI copilot, and the system learns from resolved cases. Every concept, from routing and rendering to authentication, file uploads, email notifications, and deployment, is applied to this single project. By the end, you'll have a deployable application, not a collection of disconnected examples.

What makes this book different?

AI integration is a first-class citizen. Five dedicated chapters cover the Vercel AI SDK in depth: text generation with streaming, chat interfaces, structured output with Zod, tool calling, and Retrieval-Augmented Generation (RAG) with pgvector. No other Next.js book teaches this.

One project from start to finish. HelpDesk AI grows with each chapter. You'll implement real features like role-based access control, rich text editors, presigned S3 uploads, Server-Sent Events, Sentry monitoring, and Mixpanel analytics. All in the context of a single application that actually makes sense together.

From tutorial to production. This book doesn't stop when the feature works in localhost. Part V covers testing (Vitest, Playwright), security (OWASP, prompt injection), performance optimization, monitoring, and deployment to Vercel and self-hosted environments with Docker.

AI-assisted development. A dedicated chapter on Claude Code, covering CLAUDE.md conventions, custom slash commands, and MCP server integration, reflects how modern software is actually built.

Who is this book for?

Experienced TypeScript/JavaScript developers who want to use Next.js productively
Developers switching from Java, C#, Python, or Go into the React/Next.js ecosystem (Part I provides a fast-track into TypeScript and React)
CTOs and tech leads evaluating AI integration for their products

What's in the book?

The book is organized in six parts:

Part I: Fundamentals. TypeScript, Modern JavaScript, React basics and advanced patterns
Part II: Next.js Core Concepts. Project setup, routing, rendering strategies, data fetching, styling and UI components
Part III: Full-Stack Architecture. Project architecture, Prisma and databases, authentication (Auth.js), forms with S3 uploads, email with AWS SES, state management with Zustand, real-time with SSE
Part IV: AI Features. Vercel AI SDK, text generation and streaming, chat interfaces, structured output, tool calling, RAG with pgvector
Part V: Production. Testing, performance, security, monitoring (Sentry + Mixpanel), Vercel deployment, self-hosting with Docker
Part VI: Advanced Topics. Internationalization, the Next.js ecosystem, AI-assisted development with Claude Code
