Integrating useSearchParams Hook

In the example component ProductsPage, we integrate useSearchParams to manage query parameters.

Here's a breakdown of the code:

  1. We import the necessary dependencies: useState, useEffect, and useSearchParams from React Router;
  2. We initialize the state inside the component using useState. The companies state holds the data to be displayed, and we use the setCompanies function to update it;
  3. We create a function updateCompanies to filter the data based on query parameters. The function takes the current query parameters as a URLSearchParams instance and uses them to filter the data. In this case, it filters by the "name" parameter;
  4. We use the useEffect hook to run the updateCompanies function when the component mounts and whenever the query parameters change. This ensures that the displayed data is kept in sync with the URL;
  5. The handleChange function updates the "name" query parameter in response to user input. When the input field changes, it calls setSearchParams with the new parameter value;
  6. In the component's return statement, we render an input field for user input and a list of companies based on the filtered data.

This code demonstrates how to integrate useSearchParams and React Router to create a dynamic web application that responds to changes in query parameters.
