Out of order streaming support for Astro.
⚠️ This is little more than a proof of concept at this point. Use it if you dare, but know that I'm not (yet) using it in production myself.
npx astro add astro-suspense---
import { Suspense } from "astro-suspense/components";
import SlowComponent from "./SlowComponent.astro";
---
<Suspense>
<p slot="fallback">Loading...</p>
<p slot="error">Something went wrong</p>
<SlowComponent />
</Suspense>For view transitions you need to replace Astro's default <ViewTransitions /> with this package's <SuspenseViewTransitions />.
