Real-World Next.js

Introduction

The book "Real-World Next.js" by Michele Riva is a practical guide to building high-performance, scalable, and production-ready web applications using the Next.js framework. Published in 2022, the book immediately became a bestseller among React and Next.js developers. In 354 pages, the author, a recognized expert and contributor to Next.js, shares not only syntax but also deep principles of architecture, optimization, and deployment. The book is written in TypeScript, making it especially valuable for the modern ecosystem.

What is this book about?

"Real-World Next.js" covers the full development cycle: from project setup to cloud deployment. The main focus is on real-world scenarios that a developer encounters in a production environment. The book is not overloaded with theory — each section is backed by code examples and practical advice.

Main topics:

• Next.js Architecture: file system analysis, routing, API routes, middleware.
• Rendering Strategies: SSR (Server-Side Rendering), SSG (Static Site Generation), ISR (Incremental Static Regeneration) — when and what to choose.
• Performance Optimization: code splitting, lazy loading, caching, image and font optimization.
• Working with Data: integration with databases, GraphQL, REST API, client-side and server-side state management.
• Authentication and Authorization: JWT, OAuth, sessions, route protection.
• Testing: unit tests, integration tests, e2e with Cypress and Playwright.
• Deployment and DevOps: Vercel, Docker, CI/CD, monitoring and logging.
• TypeScript: strict typing, generics, types for API and props.

Who is this book for?

The book is aimed at developers already familiar with React and the basics of JavaScript. It will be useful both for beginners in Next.js and for experienced professionals looking to deepen their knowledge of production practices. If you are transitioning from Create React App to Next.js or want to master server-side rendering — this is an ideal start.

What will the reader learn?

• How to set up a Next.js project from scratch with TypeScript.
• How to choose between SSR, SSG, and ISR for different pages.
• How to create custom API routes and middleware.
• How to optimize performance: from bundle to Core Web Vitals.
• How to implement authentication and data protection.
• How to write tests for components, pages, and APIs.
• How to deploy an application on Vercel and configure CI/CD.
• How to work with dynamic routes and i18n.

Strengths of the book

• Practical focus: every example is ready-to-use code, not abstract theory.
• Relevance: the book is based on Next.js version 12, but the concepts apply to newer versions as well.
• Depth: the author explains not only the "how" but also the "why" — architectural decisions, trade-offs, and best practices.
• TypeScript-first: all examples are in TypeScript, which improves code quality and readability.
• Structure: logical progression from simple to complex, with repetition of key points.
• Real-world scenarios: production cases — errors, debugging, monitoring, working with API limits.

Who is recommended

The book is a must-read for anyone who wants to professionally work in frontend development with Next.js. I especially recommend it to:

• React developers transitioning to Next.js.
• Full-stack engineers building modern web applications.
• Team leads and architects choosing a stack for a project.
• Students and course graduates looking to delve into production development.
