Kurzbeschreibung des Verlags

React performance optimization is changing. The question is no longer just where to add useMemo, useCallback, or memo, but how to work confidently with the React Compiler in a real production application.Production React with the React Compiler is a practical, step-by-step guide for developers who already understand the basics of React and want to adopt compiler-assisted optimization without turning the process into a confusing experiment.Rather than focusing on compiler theory, this book follows one continuous React project from initial setup through production readiness. You will learn how React Compiler fits into the build process, how to configure it with React 19 and Vite, how to verify that compilation is actually happening, and how to recognize compiler-generated optimization instead of simply assuming everything worked.You will then move into the practical issues that matter when working with an existing application: reducing unnecessary manual memoization carefully, writing components the compiler can optimize, investigating skipped components, troubleshooting build and runtime problems, measuring performance changes, and introducing compiler coverage gradually rather than making risky application-wide changes all at once.Inside, you will learn how to: - Understand the shift from manual memoization to compiler-assisted optimization- Set up React Compiler in a React 19 and Vite project- Verify compiler activity using React DevTools and generated build output- Evaluate existing useMemo, useCallback, and memo usage before removing it- Refactor React code that prevents effective optimization- Diagnose compiled, skipped, and unoptimized components- Troubleshoot build failures and unexpected runtime behavior- Establish before-and-after performance baselines- Measure rendering behavior without relying on guesswork- Introduce compiler optimization gradually and safely- Build a practical production-readiness checklist before rolloutThe book keeps the workflow intentionally focused. You will not be buried in compiler internals, unrelated frameworks, or advanced infrastructure that does not help you accomplish the main objective. Instead, each chapter builds on the previous one so you can configure, inspect, test, troubleshoot, and validate the same application as your understanding develops.This book is for React developers who know components, props, state, hooks, and basic development commands but want a clearer path into modern React optimization. You do not need previous experience with compiler internals or advanced performance engineering to follow along.If you want to move beyond scattered optimization tricks and develop a repeatable workflow for introducing React Compiler into real applications, this guide will take you from first configuration to a controlled production rollout.
