App Router Skill
Overview
Master Next.js 14+ App Router with server components, layouts, and modern routing patterns.
Capabilities
- Layouts: Root layout, nested layouts, templates
- Server Components: Default server rendering
- Client Components: Interactive with 'use client'
- Route Groups: (folder) for organization
- Parallel Routes: @slot for simultaneous rendering
- Intercepting Routes: (.) notation patterns
Examples
// app/layout.tsx
export default function RootLayout({
children,
}: {
children: React.ReactNode
}) {
return (
<html lang="en">
<body>{children}</body>
</html>
)
}
// app/dashboard/page.tsx
export default async function DashboardPage() {
const data = await fetchData() // Server-side
return <Dashboard data={data} />
}Best Practices
- Use server components by default
- Add 'use client' only when needed
- Leverage layouts for shared UI
- Use loading.tsx for suspense
