How do you handle query parameters in React Router?
In React Router, you can handle query parameters using the useLocation
hook or the location
prop provided by the Route
component. Here’s how you can do it:
Javascript
import { useLocation } from 'react-router-dom' ; function MyComponent() { const location = useLocation(); const queryParams = new URLSearchParams(location.search); const paramValue = queryParams.get( 'paramName' ); // Use paramValue in your component logic } |
This example uses the useLocation
hook to access the current location object, including the search string containing query parameters. You can then parse the search string using the URLSearchParams API to extract the query parameters.
