Solved: adding parameters to url react router

The main problem related to adding parameters to URL React Router is that the parameters can be easily manipulated by users. This can lead to security issues, as malicious users could potentially use the parameters to gain access to unauthorized resources or data. Additionally, if the parameter values are not properly validated, it could lead to unexpected behavior in the application. Finally, if too many parameters are added, it can cause performance issues due to increased complexity of the URL.

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

    <Route path="/user/:username">
      <User />

    <Link to="/user/john">John</Link>

    function User() {
      let { username } = useParams();

      return (
        <div>{username}</div>   // renders 'john' when the link is clicked. 


1. import { BrowserRouter as Router, Route, Link, useParams } from “react-router-dom”;
// This imports the components from the react-router-dom library that will be used in this code.

2. // This creates a router component that will handle navigation between different routes.

3. // This creates a route with a dynamic parameter of ‘username’.

4. // This renders the User component when this route is matched.

5. John // This creates a link to the /user/john route which will render the User component with ‘john’ as the username parameter when clicked on.

6. function User() { //This is a functional component that takes in username as an argument and renders it inside of div tags when called upon by clicking on the Link above it .

7. let { username } = useParams(); //This uses destructuring to get access to username from useParams().

8. return (


); //This returns a div element containing whatever value was passed into username which in this case would be ‘john’.

What is React router

React Router is a routing library for React applications. It provides the core components and functions necessary to create a single-page application (SPA) with navigation between different pages. It allows developers to define routes, which are paths that map to specific components in the application. React Router also provides features such as redirects, dynamic route matching, and query parameters.

Parameters to URL

Parameters to URL in React Router allow developers to pass dynamic data from the URL to the React components. This is useful for creating dynamic routes that can be used for displaying different content based on the parameters passed in the URL. For example, a route like “/user/:id” could be used to display a user profile page with an id parameter passed in the URL. Parameters can also be used for filtering data or other operations that require dynamic data from the URL.

How do I add a parameter to a URL in React

Adding parameters to a URL in React Router is done using the “params” object. This object allows you to pass in key-value pairs that will be added to the URL. To add a parameter, simply add it to the params object like so:

const params = { param1: ‘value1’, param2: ‘value2’ };

Then, when creating your route, you can pass in the params object as an argument like so:

The parameters will then be added to the URL when navigating to this route.
