Preact streaming / DPU playground #

Harness for experimenting with Preact Suspense HTML streaming and swapping stock <preact-island> patches for Declarative Partial Updates (DPU).

Demos are plain <Suspense> + thrown promises — not Pracht defer() / use(). Streaming SSR comes from a vendored build of Pracht PR #340 (streaming: true). Refresh with npm run sync:pracht-pr.

Setup #

npm install
npm run dev

Open http://localhost:3004.

Verify streaming #

DevTools → Network → the document → Response (not view-source:)
Reload — fallbacks first (), then <preact-island> (or your DPU markers)

Examples #

Route	What it shows
`/basic`	One Suspense boundary
`/parallel`	Sibling boundaries resolve independently
`/nested`	Outer then inner
`/out-of-order`	Fast sibling before slow
`/grid`	100 Suspense cells

Where to hack DPU #

Today preact-render-to-string emits Suspense markers + <preact-island> and the browser CE swaps them in. To try DPU, alias or patch:

preact / preact-render-to-string (what the stream emits)
client apply path (stock island CE vs DPU)

Keep page components on Suspense so the only moving part is how resolved HTML is applied.
