React Hooks Development Tutorials, Guides & Insights

With these steps, you've set up a basic state management system using Zustand without the need for additional boilerplate or context providers.

While both Zustand and Redux serve the purpose of state management in React applications, they differ significantly in their approach and complexity.

import React from 'react';

const ChildComponent = React.memo(({ name }) => {
  console.log('Rendering ChildComponent');
  return <div>Hello, {name}!</div>;
});

function ParentComponent() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <ChildComponent name="John" />
      <button onClick={() => setCount(count + 1)}>Increment Count</button>
      <p>Count: {count}</p>
    </div>
  );
}

In this example, ChildComponent only re-renders if the name prop changes, even when the parent component re-renders due to state changes.

import React from 'react';
import useFetch from './useFetch'; // Ensure correct import path

function UserList() {
    const { data, loading, error } = useFetch('https://jsonplaceholder.typicode.com/users');

    if (loading) return <p>Loading...</p>;
    if (error) return <p>Error: {error.message}</p>;

    return (
        <ul>
            {data.map(user => (
                <li key={user.id}>{user.name}</li>
            ))}
        </ul>
    );
}

export default UserList;

• Reusability: The useFetch hook can be used across different components and applications, reducing code duplication and simplifying API interaction.
• Loading and Error States: Automatically manages loading and error states, providing a consistent way to handle asynchronous operations.
• Cleanup Handling: Prevents state updates on unmounted components, reducing potential memory leaks and ensuring stability.
