Prompt Title: Using React Query.

Sure, I can help with that!

Assuming that you have a form that allows users to add new data and you want the page to reload after a new user is added, you can use React Query's mutate function to update the cache and then use window.location.reload() to reload the page.

Here's an example code snippet:

jsxCopy code
import { useQuery, useMutation } from 'react-query';

function UserList() {
  const { isLoading, data, error, refetch } = useQuery('users', () =>
    fetch('/api/users').then((res) => res.json())
  );

  const { mutate } = useMutation((newUser) =>
    fetch('/api/users', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(newUser),
    })
  );

  const handleSubmit = (event) => {
    event.preventDefault();
    const formData = new FormData(event.target);
    const newUser = Object.fromEntries(formData.entries());
    mutate(newUser, {
      onSuccess: () => {
        refetch();
        window.location.reload();
      },
    });
  };

  if (isLoading) {
    return <div>Loading...</div>;
  }

  if (error) {
    return <div>Error: {error.message}</div>;
  }

  return (
    <div>
      <table>
        <thead>
          <tr>
            <th>ID</th>
            <th>Name</th>
            <th>Email</th>
          </tr>
        </thead>
        <tbody>
          {data.map((user) => (
            <tr key={user.id}>
              <td>{user.id}</td>
              <td>{user.name}</td>
              <td>{user.email}</td>
            </tr>
          ))}
        </tbody>
      </table>
      <form onSubmit={handleSubmit}>
        <label>
          Name:
          <input type="text" name="name" />
        </label>
        <label>
          Email:
          <input type="email" name="email" />
        </label>
        <button type="submit">Add User</button>
      </form>
    </div>
  );
}

In this example, we use the useMutation hook to create a mutation function that sends a POST request to the /api/users endpoint with the new user data. We then use the onSuccess callback to refetch the data using the refetch function from useQuery and reload the page using window.location.reload().

When the user submits the form, we extract the form data using FormData and pass it to the mutate function. If the mutation is successful, the onSuccess callback is triggered and the page is reloaded.

I hope this helps! Let me know if you have any further questions.
