Improving Performance using React Server Components!
summary
Live-codes a tiny server that streams HTML and replaces fallbacks by sending template+script pairs, implementing Suspense semantics with a small waiter class; demonstrates out-of-order streaming and streamed HTML diffs, embeds images as base64 data URIs to defer slow resources, and highlights a CDN + function partial pre-rendering pattern. Everything runs over plain HTTP streaming with no framework or hydration required, the demo works end‑to‑end and the claim is that this avoids premature use client while improving perceived performance.
