Rendering

HTML Head and Metadata

Set titles and metadata per route so SSR, hydration, and client transitions keep SEO and announcements in sync.

seoheadmetatitle

Each route can contribute document metadata. The framework renders it on the server and reconciles the managed head region during soft transitions.

Minimal working example

export function head() {
  return <title>Task Tracker | Open Tasks</title>;
}

export function meta() {
  return {
    description: "Track open work with Bun-native SSR and soft transitions.",
    "og:title": "Task Tracker | Open Tasks",
    "og:type": "website",
    keywords: "tasks,react,bun,ssr",
  };
}

Why this matters

Accessible client transitions rely on unique route titles. Search engines and social previews do too.

Rules

  • <title> should resolve to a single string value.
  • Keep metadata deterministic between server render and hydration.
  • Prefer route-specific titles over generic app-wide titles.
