Stop Unmounting: Unlock Next-Level Performance with React 19.2's New Activity API
Are you still using conditional rendering to hide parts of your app, only to lose all their state when they disappear? It's time to upgrade your performance game! React 19.2 introduces the <Activity /> component, a revolutionary API that lets you keep components mounted, preserving their entire state and DOM, while pausing expensive side-effects like API calls and event listeners.
Join us to dive deep into how <Activity /> works—from its three rendering states to its deep integration with the Suspense and Scheduler pipelines. We'll explore practical examples like tabbed interfaces, pre-rendered components for instant navigation, and how this one component can dramatically simplify your code and boost your user experience. We'll also touch on other key 19.2 updates like useEffectEvent and Partial Pre-rendering to make sure you're ready for the modern React era.
Learn how to stop destroying state and start managing component lifecycle the React 19.2 way!
