An interactive deep-dive into React Server Components, modern rendering architecture, and the React 19 ecosystem
This isn't a collection of slides or static docs — it's a live, working codebase you can poke at, break, and learn from. Every concept is backed by a real implementation you can trace from the server to the browser, because reading about RSC and actually internalizing it are two different things.
When React Server Components first landed in stable Next.js, the mental model felt genuinely different from anything React had done before. The docs were good, but reading about it and actually internalizing it are two different things. I wanted a codebase I could poke at — one where I could break things, observe what happened at the network layer, and understand why the decisions were made the way they were.
There was also the timing: React 19 shipped alongside a brand-new compiler, new hooks, and the View Transitions API reaching a point where it was actually usable. It felt like the right moment to build something that tracked all of it in one place rather than jumping between isolated demos.
The project is organized around five major areas — each one a living, interactive demonstration rather than a static code snippet.
Every page defaults to a React Server Component. Client code only ships where interactivity is truly needed — keeping bundles lean and page loads fast.
Suspense boundaries and streaming SSR deliver instant shell loads. Data-heavy sections resolve progressively without blocking the page.
Theme toggling and page navigations use the native View Transitions API for smooth, cinematic state changes — no JavaScript animation libraries required.
Jump into the interactive demos, trace requests through the rendering pipeline, and build real intuition for how modern React works under the hood.
