This workshop dives into the core of building resilient, scalable, production-ready applications with React and Next.js, grounding you in a pragmatic approach to software development. We’ll tackle common web performance pitfalls, showing you how to make impactful optimizations without compromising readability, maintainability, or speed, essential when delivering under tight timelines. You’ll explore resilience patterns that enable your applications to perform reliably under real-world demands along with how to make the right compromises, whether you’re building for early-stage platforms or scaling up to serve millions of global users.

Covering React reconciliation fundamentals, we’ll provide the context needed for structuring large-scale component architectures, alongside best practices for designing components that stay maintainable over time. Through a case study using TanStack Query, you’ll tackle data fetching at scale to ensure optimal app performance with complex data requirements.

Finally, we’ll focus on post-deployment strategies, including setting up observability and monitoring tools to detect issues early. This workshop provides an adaptable playbook for creating robust applications that endure, building a skill set to navigate the evolving problem spaces and needs across different project stages, whether you’re developing from scratch or scaling for global audiences.

This talk explores the intersection of Next.js, React Query, and the Backend for Frontend (BFF) design pattern, three vital elements pieces that help solve the puzzle of performant and scalable data fetching.

I’ll start by discussing Next.js and its capabilities for React applications, highlighting its features like server rendering and data pre fetching, and route pre-fetching. I’d then delve into client data fetching and state management, showcasing how React Query brings a new perspective to managing server state hydration in React applications, simplifying data fetching, caching, synchronization, and updates.

The last part of the talk will take the topic further by introducing the Backend For Frontend (BFF) design pattern, demonstrating how a BFF can be integrated with NextJs API handler to work seamlessly as a Proxy with a React application, enhancing user experience and performance by spreading the load of large payloads.

Throughout the talk, real-world examples will be used to provide a practical understanding of these topics.

Building a server driven UI with React is perfect as Reacts dynamic nature makes it easy to render and update UIs based on API responses but it still requires many round trips over the network. React 19 and RSCs are a perfect solution to this problem! By leveraging the new features in React 19 we can now build an even more performant server driven UI. In this talk I’ll demo how I’ve been able to leverage React 19 and RSCs in an enterprise application to build server driven UIs.
