Modern React Patterns You Should Know in 2024

React has evolved significantly over the years, and with it, the patterns and best practices that make our applications more maintainable, performant, and scalable. In this post, we'll explore some of the most important React patterns that every developer should know in 2024.

1. Server Components

React Server Components represent a paradigm shift in how we think about React applications. They allow us to render components on the server, reducing the amount of JavaScript sent to the client.

Copy
// Server Component
async function BlogPost({ id }) {
  const post = await fetchPost(id);
  return <Article post={post} />;
}

2. Compound Components

The compound component pattern allows you to create flexible and reusable components that work together as a cohesive unit.

Copy
function Modal({ children }) {
  return (
    <div className="modals">
      {children}
    </div>
  );
}

Modal.Header = ({ children }) => <div className=\"modal-header\">{children}</div>;
Modal.Body = ({ children }) => <div className=\"modal-body\">{children}</div>;
Modal.Footer = ({ children }) => <div className=\"modal-footer\">{children}</div>;

3. Custom Hooks for Logic Separation

Custom hooks help separate business logic from presentation logic, making components more focused and testable.

Copy
function useCounter(initialValue = 0) {
  const [count, setCount] = useState(initialValue);

  const increment = () => setCount((c) => c + 1);
  const decrement = () => setCount((c) => c - 1);
  const reset = () => setCount(initialValue);

  return { count, increment, decrement, reset };
}

Conclusion

These patterns represent just a fraction of what's possible with modern React development. By incorporating these patterns into your workflow, you'll write more maintainable and scalable React applications.
