A Paradigm Shift
Next.js 14 and the App Router introduce a new way of thinking about building React applications. Server Components allow us to move data fetching and rendering to the server, reducing the amount of JavaScript sent to the client.
Benefits
- Improved Performance: Less client-side JavaScript means faster initial page loads and better interactivity.
- Direct Data Access: Server Components can directly access server-side resources like databases and file systems without needing to create API endpoints.
- Enhanced Security: Sensitive data and logic can be kept on the server, reducing the risk of exposure.
When to Use Them
Server Components are ideal for parts of your UI that are not highly interactive, such as displaying static content, blog posts, or product details. Client Components should be used for interactive elements that require state and event listeners.
