Understanding React Server Components
React Server Components represent a paradigm shift in how we build React applications.
What Are Server Components?
Server Components render on the server and send HTML to the client:
- Zero bundle size
- Direct database access
- Improved performance
Benefits
- 1Faster Initial Load: Less JavaScript to download
- 2Better SEO: Fully rendered HTML
- 3Simpler Data Fetching: No client-side state management needed
When to Use
- Data fetching
- Static content
- Layout components
- Interactive UI
- Browser APIs
- State management
