• Implementing progressive content loading with Suspense boundaries
• Reducing client bundle size with server-side rendering
• Accessing server-side data sources directly in components

React use Hook

• Streaming data from server to client without blocking
• Handling promises in Client Components with the use hook
• Building responsive UIs with progressive enhancement
• Optimizing perceived performance with streaming

Accessibility with useId

• Generating unique IDs for ARIA relationships
• Preventing ID conflicts in multiple component instances
• Server-side rendering compatibility for accessibility
• Building accessible forms and interactive components

📚 Demo Components

1. Server Components + Streaming SSR

File: app/components/StreamingSSRDemo.tsx

Demonstrates React 19 Server Components with streaming SSR:

• Async Server Components with direct database/API access
• Progressive content loading with Suspense boundaries
• Reduced client bundle size through server-side rendering
• Real-world data fetching patterns

2. Server-Client Promise Streaming

File: app/components/PostWithCommentsDemo.tsx

Shows the use hook for seamless server-client streaming:

• Critical content (post) rendered immediately on server
• Lower-priority content (comments) streamed to client
• Promise-based data flow between server and client
• Enhanced user experience with progressive loading

3. useId Hook for Accessibility

File: app/components/UseIdDemo.tsx

Comprehensive accessibility patterns with useId:

• Unique ID generation for ARIA relationships
• Multiple related elements with shared ID prefixes
• Server-side rendering compatibility
• Form accessibility best practices

🎨 UI Components

The project includes a set of reusable UI components:

• Card - Container component with consistent styling
• DemoTitle - Standardized demo section headers
• Code - Syntax-highlighted code blocks
• Button, Input, Textarea - Form components
• FallbackLoading - Loading states for Suspense

🔧 Technologies Used

• Next.js - React framework with App Router
• React - Modern React with Server Components
• TypeScript - Type-safe JavaScript
• Tailwind CSS - Utility-first CSS framework
• Turbopack - Next-generation bundler
• ESLint - Code linting and formatting

📖 Key Concepts Explained

Server Components

Server Components run on the server and can access databases, file systems, and other server-side resources directly. They're not sent to the client, reducing bundle size.

Streaming SSR

Progressive content loading where the page shell renders immediately, and content streams in as it becomes available, improving perceived performance.

use Hook

React's use hook allows Client Components to consume promises passed from Server Components, enabling seamless server-client data streaming.

useId Hook

Generates unique, stable IDs for accessibility attributes, ensuring proper ARIA relationships and server-side rendering compatibility.
