What RSCs can do in Next.js today

Abstract

Building app-like UX on the web has historically meant reaching for an SPA. You ship the data layer to the browser, manage a client cache, juggle loading states, coordinate mutations, and write a lot of code to keep the UI feeling fast and fresh. The result can be great, but the cost is high, and the model gets harder to maintain as your app grows.

Next.js takes a different path. Since React Server Components first landed, we’ve been working toward a way to build where each piece of your app runs where it belongs, while the mental model stays the same: components. In this talk, you’ll see how that translates into instant-feeling UX, streamed UI, fresh data, coordinated updates, caching across the stack, and strong Core Web Vitals that hold up as your product scales.
