Getting started with React Router: Basics and Configuration

If you're developing a web application with React, you may have found that navigating between different pages and URLs can be a challenge. Fortunately, React Router is a powerful and easy-to-use tool that can help you manage this process. In this article, we'll go over the basics of React Router and how to configure it in your project.

What is React Router?

React Router is a popular routing library for React applications. It provides a way to manage the navigation and URLs of a React app by defining routes and rendering components based on those routes. Essentially, React Router allows you to create a single-page application with multiple "pages" that are dynamically rendered based on the user's navigation.

Installing React Router

Before you can use React Router in your project, you'll need to install it. You can do this using npm or yarn by running the following command:

npm install react-router-dom


yarn add react-router-dom

Once React Router is installed, you can start using it in your app.

Basic Routing

To get started with React Router, you'll need to define some routes in your app. A route is simply a URL that maps to a specific component in your app. For example, you might define a route for the home page, a route for a user's profile page, and a route for a blog post.

Here's an example of how to define routes in your app:

import { BrowserRouter as Router, Route, Switch } from "react-router-dom";
import Home from "./Home";
import Profile from "./Profile";
import BlogPost from "./BlogPost";

function App() {
  return (
        <Route exact path="/" component={Home} />
        <Route path="/profile" component={Profile} />
        <Route path="/blog/:id" component={BlogPost} />

In this example, we're using the BrowserRouter component from React Router to define our router. Inside the BrowserRouter, we have a Switch component that renders the first Route that matches the current URL.

Each Route component takes two props: path and component. The path prop is the URL path that the route should match, and the component prop is the React component that should be rendered when the route matches.

Note that we're using the exact prop on the home route. This ensures that the home page is only rendered when the URL path exactly matches "/", and not when there are additional path segments.

Navigating between Routes

Once you've defined your routes, you'll want to provide a way for users to navigate between them. React Router provides a few different components for this, including Link and NavLink.

Here's an example of how to use the Link component:

import { Link } from "react-router-dom";

function Navbar() {
  return (
          <Link to="/">Home</Link>
          <Link to="/profile">Profile</Link>
          <Link to="/blog/123">Blog Post</Link>

In this example, we're using the Link component to create links to our different routes. The to prop on each Link component specifies the URL that should be navigated to when the link is clicked.

Note that when using the Link component, you don't need to worry about manually updating the URL or reloading the page. React Router takes care of all that for you.

Passing Parameters

In the previous examples, we defined a route for a blog post that takes an id parameter. You can access this parameter in your component using the useParams hook from React Router.

Here's an example of how to use the useParams hook:

import { useParams } from "react-router-dom";

function BlogPost() {
  const { id } = useParams();

  return (
      <h1>Blog Post {id}</h1>
      {/* Rest of the blog post */}

In this example, we're importing the useParams hook from React Router and calling it in our BlogPost component. The useParams hook returns an object with the parameters passed in the URL.


There may be times when you want to redirect the user to a different route. React Router provides a Redirect component for this purpose.

Here's an example of how to use the Redirect component:

import { Redirect } from "react-router-dom";

function ProtectedRoute() {
  const isAuthenticated = false;

  if (!isAuthenticated) {
    return <Redirect to="/login" />;

  return <h1>Welcome to the protected route</h1>;

In this example, we're using the Redirect component to redirect the user to the login page if they're not authenticated. If they are authenticated, the protected route is rendered.


React Router is an essential tool for managing navigation and URLs in React applications. In this article, we covered the basics of React Router, including defining routes, navigating between them, passing parameters, and redirects.

By using React Router, you can create a seamless user experience in your React app and make it easier to navigate between different pages and URLs.
