Usage
usage.tsx
import RootLayout from '@/app/layout';export default function ExamplePage() { return ( <RootLayout> <main>Page content</main> </RootLayout> );}- Use as the App Router root layout for a Clerk-enabled Next.js application.
- Use when the application needs a shared header on every route.
- Use when light/dark theme support should be controlled through next-themes and Clerk should wrap the entire app.
- Use as a starting point for a Clerk Next.js quickstart or authenticated dashboard shell.
Examples
Dashboard shell
Wrap route content with the root layout when previewing the shared application shell.
dashboard-shell.tsx
import RootLayout from '@/app/layout';export default function DashboardPage() { return ( <RootLayout> <main> <h1>Dashboard</h1> <p>Review your account activity.</p> </main> </RootLayout> );}Marketing page shell
Render public content beneath the shared Clerk and theme providers.
marketing-page-shell.tsx
import RootLayout from '@/app/layout';export default function LandingPage() { return ( <RootLayout> <main> <section aria-labelledby='welcome-heading'> <h1 id='welcome-heading'>Welcome to the workspace</h1> <p>Sign in to continue.</p> </section> </main> </RootLayout> );}API reference
PropTypeDefaultDescription
childrenReact.ReactNode—The route content rendered below the Header inside the ClerkProvider and ThemeProvider. This prop is required by the layout component.
Accessibility
- Sets the document language to English with lang='en'.
- Preserves the supplied children so pages can provide their own semantic landmarks, headings, and focusable content.
- The layout itself does not add a main landmark; route content should provide appropriate semantic structure such as main, nav, and headings.
- ThemeProvider uses class-based theme switching with suppressHydrationWarning to avoid hydration warnings caused by the initial theme state.
- The Header component is responsible for the accessible naming, navigation semantics, and controls of the shared header.
