Streaming HTML with React Suspense
Concept
Depth: ●●○○○
Using Suspense boundaries to stream HTML and improve perceived performance.
Streaming HTML with React Suspense
Suspense isn't just for loading spinners. It enables streaming, fundamentally changing how pages load.
How Streaming Works
Without streaming: Server waits for all data, then sends complete HTML.
With streaming: Server sends HTML as it's ready, filling in Suspense boundaries as data resolves.
Implementation
The user sees the page shell immediately, with slow components streaming in as they're ready.
