React Components for both the Client & the Server

Server components are UI components that run on the server, offering performance improvements like smaller bundle size and improved data fetching.

Server components provide performance improvements by reducing bundle size and improving data fetching. They can also access the file system and database directly.

Server components run on the server and can have access to server-side resources, while client components run in the browser, allowing for interactivity and direct DOM manipulation.

Using both server and client components can lead to code duplication and the need to manage separate components for similar functionalities.

Integration can be achieved by using the composition pattern, where server components can render client components, and by separating components into agnostic parts that can be rendered on both the client and server.

The composition pattern in React allows server components to render client components, but not the other way around. It helps in integrating server and client components effectively.

Interactivity can be added by wrapping server components with client components that handle client-side logic and events, using the 'use client' directive when necessary.

The 'use client' directive is used to indicate that a component should be treated as a client component, allowing it to handle client-side interactivity and state management.

Code duplication can be minimized by creating agnostic parts for components that can function on both the client and server, and by wrapping them with client-specific logic as needed.

Keeping certain code, like large libraries for syntax highlighting, on the server can reduce the client bundle size, improving performance by ensuring only necessary code is shipped to the client.
