In src/features/users/components/UserList.js:

import React, { useEffect } from 'react';
import { useSelector, useDispatch } from 'react-redux';
import { fetchUsers } from '../usersSlice';

const UserList = () => {
  const dispatch = useDispatch();
  const { entities, status, error } = useSelector((state) => state.users);

  useEffect(() => {
    if (status === 'idle') {
      dispatch(fetchUsers());
    }
  }, [dispatch, status]);

  if (status === 'loading') return <p>Loading...</p>;
  if (status === 'failed') return <p>Error: {error}</p>;

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

export default UserList;

   Cache::forget('shared_data');

   // Regenerate cache
   Cache::rememberForever('shared_data', function () {
       return [
           'max_uploads' => 10,
           'api_rate_limit' => 100,
           'features' => [
               'uploads_enabled' => true,
               'comments_enabled' => false,
           ],
       ];
   });

If the data changes frequently, use a timed cache:

• Minimize deep nesting of flex containers.
• Avoid recalculating layout multiple times with CSS transitions.
• Test on multiple devices to ensure performance is consistent.

Flexbox is an essential tool for creating responsive and adaptive web designs. By mastering the advanced techniques outlined in this tutorial, you can build flexible layouts that respond to dynamic content and various screen sizes. Remember to test your designs across different devices and screen sizes to ensure they function as expected in real-world scenarios.

• Leverage modern JavaScript features like arrow functions, destructuring, template literals, and the spread/rest operators to write more concise and expressive code.

• Code readability should always be a priority. Use descriptive names for variables, functions, and classes. Avoid deeply nested code, and follow consistent coding conventions.
