Streaming SSR

Progressive HTML delivery

Streaming SSR sends HTML in chunks as it's generated. Users see content progressively.

Traditional SSR: Wait for all data, then send complete HTML.

Streaming SSR: Send HTML shell immediately, stream content as ready.

Benefits:

Faster time to first byte
Progressive rendering
Better perceived performance

React $18$ + Suspense enables this:

<Suspense fallback={<Loading />}>
  <SlowComponent />
</Suspense>

The shell renders immediately. SlowComponent streams when ready.
