Scaling SPAs to hundreds of engineers contributing to the same codebase can be challenging. In particular, highly interactive applications with a lot of client-side state. Who owns a certain state? How do we create boundaries between state in different domains? How do we optimise critical paths for different interactions? In this talk I'll explore some patterns and libraries such as Jotai to answer these questions and more.

Performance advice tells us to reduce bundle size, minimize re-renders, and optimize everything to the extreme. But do we really need to? Is there anything else we can explore to make our apps look and feel faster—and if we’re lucky, actually be faster?

In this talk, we will review some conventional wisdom and explore techniques beyond it, like different UX strategies, overfetching, and modern Web APIs. We’ll even ask an unexpected question: Can SEO and LSO (LLM Search Optimisation) help with performance?

Next.JS has long been the favored framework for React enthusiasts, but with the recent Next V13 update, things have taken an intriguing turn. The new version has introduced some highly anticipated features that have left developers with mixed feelings. The challenges arise from React's extensive history predating Next.JS, making it difficult to seamlessly integrate new functionalities like the 'Servicer Action' and others. However, Next.JS stands out as one of the first frameworks to tackle the server/client territory within a single code block. This innovative approach is still in its early stages and promises to shape the future of frameworks to come. To delve deeper into this exciting topic, make sure to attend our event.
