Advanced Modern JavaScript Library Engineering
Build React-Class UI Libraries, Renderers, Routers, Schedulers, SSR Pipelines, and Web-Scale APIs from First Principles
About this book
This book is for developers who already know how to build web applications and now want to understand how the libraries underneath them are designed. You will learn the core engineering patterns behind React-class tools: virtual trees, component instances, hooks, signals, schedulers, event systems, SSR, hydration, routing, streaming, workers, package exports, testing, and security.
The book deliberately avoids magical explanations. Every major idea is reduced to a small implementation, then expanded into design warnings and production trade-offs.
The goal is not to replace React or Next.js. The goal is to make you capable of understanding them deeply and designing your own powerful JavaScript libraries with discipline.
