Solved: react router url params

The main problem related to React Router URL params is that they can be difficult to use in dynamic routes. This is because the URL params are static and cannot be changed after the route has been created. This means that if a user needs to access a different page with different parameters, they will need to create a new route for each parameter combination. Additionally, when using URL params, it can be difficult to keep track of all the possible combinations and make sure that each one is properly handled by the router.

import {
  BrowserRouter as Router,
} from "react-router-dom";

 const App = () => {

   return (

         <Route path="/user/:username" component={UserPage} />



 const UserPage = () => {

   let { username } = useParams(); // Get the username from the URL.

   return (
     <div>Hello, {username}!</div> // Render a greeting with the username. 


This code is setting up a React Router to render a page with a username from the URL.

1. The first line imports components from the React Router DOM library.
2. The App function returns the Router component with a Route component inside of it, which specifies that any URL beginning with “/user/” should render the UserPage component.
3. The UserPage function uses useParams() to get the username from the URL and then renders a greeting using that username.

URL params

URL params in React Router are pieces of data that are passed to a route as part of the URL. They allow developers to pass dynamic information to a route, such as an ID or query string. This can be used to create dynamic routes that can be used for things like displaying specific items from a database or filtering content based on user input. React Router provides tools for accessing and manipulating URL params, making it easy to use them in your application.

How do you get the URL params from a route in React

In React Router, you can access the URL params from a route using the useParams hook. This hook returns an object containing key-value pairs of the URL parameters. For example, if your route is /user/:id, you can access the id parameter with useParams().id.
