Modern React Patterns in 2024

React has evolved significantly over the years, with hooks and concurrent features reshaping how we build applications.

Server Components

Server Components allow rendering on the server with zero JavaScript sent to the client.

// This component renders on the server
async function UserProfile({ userId }) {
  const user = await fetchUser(userId);
  return <div>{user.name}</div>;
}

React Hooks Patterns

Custom Hook Composition

function useUserData(userId) {
  return useSWR(`/api/user/${userId}`, fetcher);
}

function UserProfile({ userId }) {
  const { data, error } = useUserData(userId);
  
  if (error) return <div>Error loading user</div>;
  if (!data) return <div>Loading...</div>;
  
  return <div>{data.name}</div>;
}

State Management in 2024

With React's built-in hooks and context API, many applications no longer need external state management libraries.

Conclusion

Modern React development continues to emphasize simplicity, composability, and performance.
