In React, you can access the query parameters of a URL using the URLSearchParams API provided by the browser. Here's how you can do it:

  1. Import the necessary modules:
1
import { useLocation } from 'react-router-dom';


Note: Make sure you have installed the react-router-dom package if you haven't already.

  1. Access the query parameters using the useLocation hook:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
const MyComponent = () => {
  const location = useLocation();
  const queryParams = new URLSearchParams(location.search);
  
  // Access specific query parameter values
  const paramName = queryParams.get('paramName');
  
  // Use the parameter values in your component
  // ...
};


  1. Accessing the query parameters can be placed within a component. For example, if you're using React functional components, you can include the code snippet above within your component.


Note: The useLocation hook provided by React Router returns a location object that contains the current URL's information, including the query parameters.


Now, you can access specific query parameter values by calling the get method of the URLSearchParams object initialization queryParams.get('paramName'), where 'paramName' is the name of the query parameter you want to access.


Using the above approach, you can easily retrieve and use the query parameters in your React components.
