React Router is a popular routing library for React. It allows you to easily create and manage routes in your React application. One of the things that React Router makes easy is rendering the same component with different props. This can be useful for things like displaying a list of items, or showing different views of the same data.
Render the same component with different props inside react router
To render the same component with different props, you can use the render
prop with the Route
component. The render
prop takes a function as its value, and this function will be called to render the component. The function will receive the Route
component as its first argument, and the props
object as its second argument. The props
object contains all of the props that were passed to the Route
component.
For example, let’s say we have a component called ProductList
that displays a list of products. We can use the render
prop to render the ProductList
component with different props depending on the current route.
<Route path="/products" render={(route) => { const { query } = route.location; const { page } = query; // Get the products for the current page const products = getProducts(page); // Render the ProductList component with the products return ( <ProductList products={products} /> ); }} />
In this example, the ProductList
component will be rendered with the products
prop set to the list of products for the current page.
<Route>
The Route component is perhaps the most important component in React Router to understand and learn to use well. Its most basic responsibility is to render some UI when its path
matches the current URL.
Consider the following code:
mport React from "react"; import ReactDOM from "react-dom"; import { BrowserRouter as Router, Route } from "react-router-dom"; ReactDOM.render( <Router> <div> <Route exact path="/"> <Home /> </Route> <Route path="/news"> <NewsFeed /> </Route> </div> </Router>, node ); If the location of the app is / then the UI hierarchy will be something like:<div> <Home /> <!-- react-empty: 2 --> </div> And if the location of the app is /news then the UI hierarchy will be:<div> <!-- react-empty: 1 --> <NewsFeed /> </div>
The “react-empty” comments are just implementation details of React’s null rendering. But for our purposes, it is instructive. A Route is always technically “rendered” even though it’s rendering null. When the ‘s path matches the current URL, it renders its children (your component).
If the same component is used as the child of multiple s at the same point in the component tree, React will see this as the same component instance and the component’s state will be preserved between route changes. If this isn’t desired, a unique key prop added to each route component will cause React to recreate the component instance when the route changes.

Tips for rendering the same component with different props
Here are a few tips for rendering the same component with different props:
- Use the
useParams
hook to get the parameters from the URL. - Use the
useLocation
hook to get the current location. - Use the
key
prop to ensure that the component is re-rendered when the route changes. - Use the
render
prop to customize the rendering of the component.
Conclusion
Rendering the same component with different props is a useful technique for React Router. It can be used to display a list of items, or show different views of the same data. By following the tips in this article, you can easily render the same component with different props in your React Router application.
