Building Large Scale Web Apps: A React Field Guide. By Addy Osmani and Hassan Djirdeh

“Building Large Scale Web Apps” is a toolkit to managing large-scale React applications.

React as a library allows you to start building user interfaces quickly and easily. But how do things scale as an application grows? How do you ensure that your codebase remains manageable, your performance metrics stay on point, and your team continues to work cohesively as the project evolves?

In this book, you'll uncover strategies that industry professionals use to build scalable, performant, and maintainable React applications, all without becoming overwhelmed by complexity.

Descriptive content, continous updates, and soundbites from industry professionals.

Descriptive, not prescriptive

When explaining content, we follow a descriptive approach, not prescriptive. In other words, we don’t tell you what specific tools or libraries you have to use to be successful. Rather, we focus on explaining a concept and employ certain libraries or tools to illustrate that concept.

React-focused with universal concepts

While the book is React-focused, it teaches universal concepts that transcend all web development frameworks. It's designed to enhance your understanding of building web applications that are scalable, maintainable, and adaptable, regardless of the specific technology stack.

Continous, frequent updates

Purchasing the e-book gives you access to all new content, edits, and improvements forever. In fact, we're currently working on adding three new chapters soon — Routing, User-centric API design, and React in 2024. Check out the Changelog to follow along on all the updates we'll make.

Soundbites from industry professionals

In the book, we share soundbites and thoughts from industry professionals. These soundbites are shared from start-up owners and software engineers who work at Doordash, Netflix, Spotify, and more.
