app-router（应用路由器）

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
