Next.js 15 in Action: From Zero to Production-Ready Web Apps Using React, Server Components, and the App Router

Next.js 15 in Action is a comprehensive, practical guide to building modern, scalable, production-grade applications with Next.js 15 and the latest capabilities of the React ecosystem. It takes you beyond the documentation and into real-world application development using App Router, Server Components, Server Actions, TypeScript, Edge Rendering, Turbopack, and more.

This book is written to speak directly to you. You won't find generic explanations or abstract overviews here. Every chapter is meticulously structured to connect on a personal level--walking you step by step through setting up your project, structuring scalable layouts, managing state, performing secure data mutations, optimizing performance, and deploying with confidence. You'll learn how to build and maintain production-grade apps the right way--from a seasoned engineer's perspective.

Through in-depth explanations, fully working code examples, real-world exercises, and hard-earned best practices, you'll gain a complete and grounded understanding of everything from routing and API integration to testing, CI/CD, SEO, and error monitoring with tools like Sentry and LogRocket.
