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.

The transition was seamless. Two hundred heavy rectangular shields snapped into position, locking rim-to-rim and tier-over-tier. In an instant, the company had vanished, replaced by a singular, unyielding entity: the shieldwall.

Decimus felt the weight of the press, the hot breath of the enemy through the cracks in the defense, and the steady push of his own men from behind. They were no longer individuals; they were the barrier between civilization and the dark. As the sun climbed higher, the ground grew slick with more than just the morning dew, but the wall held, an iron promise written in the dirt of the frontier. If you'd like to dive deeper into this world, I can: Describe a specific used by the soldiers. Write a scene from the perspective of the opposing force . Develop the backstory of Decimus and his rise to commander. Which direction interests you most? AI responses may include mistakes. Learn more

The impact was a deafening symphony of wood splintering against metal. The barbarians threw themselves at the line with the fury of a winter gale, their axes biting into the thick leather and wood. But the wall did not buckle. From the narrow gaps between the shields, the short gladius blades flickered like the tongues of vipers—precise, lethal, and relentless.

The dawn light caught the bronze of Decimus’s helmet, casting a long, flickering shadow across the mud of the valley floor. Behind him, the men of the Tenth were a wall of breathing iron. They didn't speak. They didn't need to. The rhythmic thump of spear butts against the earth was the only heartbeat they shared.

Ahead, the fog began to peel away from the forest edge, revealing a chaotic sea of furs and jagged steel. The northern tribes had come in numbers that would have made a lesser man’s blood turn to ice. A horn blasted, a low, mournful sound that echoed through the mountain passes, and the first wave of the horde began to roll forward. "Scuta!" Decimus roared.

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.
