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.

Despite shared cultural spaces, the transgender community faces distinct socioeconomic and systemic hurdles that set its experience apart from cisgender lesbian, gay, and bisexual individuals. Healthcare and Autonomy

The experiences of young trans women can be complex and influenced by various factors, including societal norms, cultural background, and access to resources and support. As we explore the lives of these individuals, it's essential to prioritize respect, empathy, and understanding.

Lack of social acceptance, family rejection, and systemic discrimination contribute to elevated rates of anxiety, depression, and suicidal ideation within the community.

While the acronyms link these groups together, the internal dynamics between sexual orientation and gender identity require careful distinction. Orientation vs. Identity

The community has led the cultural shift toward respecting self-identification. Normalizing the sharing of pronouns (he/him, she/her, they/them, ze/hir) has fostered safer spaces both online and offline.

There is also a growing acknowledgment of trans history: more schools are teaching about Marsha P. Johnson, Sylvia Rivera, and the Compton’s Cafeteria Riot (1966, three years before Stonewall, where trans women in San Francisco fought police). Documentaries like Disclosure (2020) analyze trans representation in Hollywood, pushing for authentic casting and storytelling.

Some other things!

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.
