Building Interactive Async UI with React 19 and Ariakit

Async UI can quickly get messy; loading flickers, slow updates, and accessibility challenges all add up. In this talk, Aurora Scharff from BitterBrains shows how to tame those problems using tools from React 19, Next.js App Router, and Ariakit.

You’ll learn how React Server Components simplify data fetching, how to handle mutations and optimistic updates, and how to build accessible components without drowning in boilerplate. This session is packed with practical strategies for building modern, interactive, and accessible async UIs that feel good to use.
