Page Component Guidelines

PAGE ARCHITECTURE RULES

Pages are COMPOSITION ONLY

Pages should be thin orchestration layers that compose smaller components:

// PERFECT: Page as composition layer (10-30 lines max)
const DashboardPage = () => {
  return (
    <PageLayout>
      <DashboardHeader />
      <DashboardMetrics />
      <div className="grid grid-cols-1 lg:grid-cols-2 gap-6">
        <DashboardCharts />
        <DashboardActivity />
      </div>
    </PageLayout>
  )
}

// NEVER: Business logic in pages
const BadDashboardPage = () => {
  const [users, setUsers] = useState([])
  const [loading, setLoading] = useState(true)
  
  useEffect(() => {
    // 50+ lines of data fetching logic
  }, [])
  
  // 200+ lines of rendering logic
  return <div>{/* massive JSX */}</div>
}

Page Organization Rules

1. Import dependencies (max 5-8 imports)
2. Call custom hooks for data/state (1-3 hooks max)
3. Return JSX composition (10-20 lines max)
4. No business logic - extract to hooks or services
5. No inline handlers - extract to components or hooks

Data Loading Pattern

```tsx
// PERFECT: Data loading in custom hooks
const UserProfilePage = () => {
  const { user, isLoading, error } = useUser()
  
  if (isLoading) return <LoadingSpinner />
  if (error) return <ErrorMessage error={error} />
  
  return (
    <PageLayout>
      <UserHeader user={user} />
      <UserDetails user={user} />
      <UserActivity user={user} />
    </PageLayout>
  )
}
