React 19.2: The async shift is finally here - LogRocket Blog

"If you're making fetch calls in a useEffect in your React app, then you're doing it wrong. We hear that every day. But what should we do instead? Well, as it turns out, the React team has heard us loud and clear. React 19.2 doesn't just patch over async problems-it rebuilds async handling from the ground up with use(), <Suspense>, useTransition(), and now View Transitions. Together, these primitives turn async logic from a necessary evil into a first-class architectural feature."

"Now, this pattern works, but you're doing a lot of repetitive makework. For example, you're managing three pieces of state ( imageId, imageData, isPending) when really you just want to show an image. The loading state logic is manual, and the error handling is often an afterthought. And chances are, every async operation looks slightly different. fetchImage in this case is just a wrapper around fetch to keep the example short."

React 19.2 rebuilds async handling with primitives like use(), <Suspense>, useTransition(), and View Transitions to make asynchronous logic a first-class architectural feature. These primitives eliminate repetitive state management patterns such as manually tracking isLoading and separate data state when fetching in useEffect. The approach centralizes loading and error handling, reduces boilerplate, and provides consistent async behavior across components. The new model enables smoother transitions between UI states, better coordination of concurrent updates, and clearer composition of async operations. Teams gain simpler, more robust patterns for data fetching and UI responsiveness without ad-hoc per-component implementations.
