Handling async operations in UI components can be tricky – flickering pending states, inefficient state updates, and unstable user experiences are common issues. Building accessible UI components presents additional challenges, as meeting accessibility requirements often requires extra effort, which can add complexity to the development process.
In the context of the Next.js App Router, this session will demonstrate how React Server Components streamline data fetching, while other React 19 tools help manage mutations, loading states, and optimistic updates more effectively. We’ll combine these with Ariakit to simplify the process of building interactive, accessible UI components with less boilerplate. You’ll leave with practical strategies for managing async operations while ensuring a smooth, reliable user experience.
