Can we share data among routes in React Router?
There are several ways that you can share data among routes in React Router.
- URL Parameters: You can pass data between routes using URL parameters. These parameters can be accessed using the
useParams()
hook in functional components orthis.props.match.params
in class components. - State Management: You can use state management libraries like Redux, Context API, or even React’s built-in state management to share data between components, including those rendered by different routes.
- Query Parameters: Query parameters are appended to the URL as key-value pairs (e.g.,
?param1=value1¶m2=value2
) and can be accessed using theuseLocation()
hook orthis.props.location.query
in class components. - Local Storage or Session Storage: You can store data in the browser’s local storage or session storage and retrieve it from any component within your application.
- Props: If components rendered by different routes are part of a parent-child relationship, you can pass data down the component tree using props.
