React Router is a JavaScript library designed specifically for React to handle client-side routing. It maps specific URL paths to React components, allowing users to navigate between different pages or sections without refreshing the entire page.

Types of React Routers

There are three types of routers in React:

  1. BrowserRouter: The BrowserRouter is the most commonly used router for modern React applications. It uses the HTML5 History API to manage routing, which allows the URL to be dynamically updated while ensuring the browser's address bar and history are in sync.
  2. HashRouter: The HashRouter is useful when you want to use a URL hash (#) for routing, rather than the HTML5 history API. It doesn't require server configuration and works even if the server doesn't support URL rewriting.
  3. MemoryRouter: The MemoryRouter is used in non-browser environments, such as in React Native or when running tests.

Features of React Router

  • Declarative Routing: React Router v6 uses the Routes and Route components to define routes declaratively, making the routing configuration simple and easy to read.
  • Nested Routes: It supports nested routes, allowing for complex and hierarchical routing structures, which helps in organizing the application better.
  • Programmatic Navigation: The useNavigate hook enables programmatic navigation, allowing developers to navigate between routes based on certain conditions or user actions.
  • Route Parameters: It provides dynamic routing with route parameters, enabling the creation of routes that can match multiple URL patterns.
  • Improved TypeScript Support: Enhanced TypeScript support ensures that developers can build type-safe applications, improving development efficiency and reducing errors.

Components of React Router

Here are the main components used in React Router:

1. BrowserRouter and HashRouter

  • BrowserRouter: Uses the HTML5 history API to keep your UI in sync with the URL.
  • HashRouter: Uses the hash portion of the URL (i.e., window.location.hash) to keep your UI in sync with the URL.
<BrowserRouter>
    (/* Your routes go here */}
</BrowserRouter>

2. Routes and Route

  • Routes: A container for all your route definitions.
  • Route: Defines a single route with a path and the component to render.
<Routes>
    <Route path="/" element={<Home />} />
    <Route path="/about" element={<About />} />
</Routes>

3. Link and NavLink

  • Link: Creates navigational links in your application.
  • NavLink: Similar to Link but provides additional styling attributes when the link is active.
<nav>
    <NavLink to="/" activeClassName="active">Home</NavLink>
    <Link to="/about">About</Link>
</nav>

Steps to Create Routes using React Router

Step 1: Initialize React Project

Run the following command to create a new React application:

npx create-react-app react-router-example
cd react-router-example

Step 2: Install React Router

Install react-router in your application write the following command in your terminal

npm install react-router-dom@6

            <h2>Home Page</h2>
            <button onClick={() =>

React Router

Uses of React Router

  1. Navigation and Routing: React Router provides a declarative way to navigate between different views or pages in a React application. It allows users to switch between views without refreshing the entire page.
  2. Dynamic Routing: React Router supports dynamic routing, which means routes can change based on the application's state or data, making it possible to handle complex navigation scenarios.
  3. URL Management: React Router helps manage the URLs in your application, allowing for deep linking, bookmarkable URLs, and maintaining the browser's history stack.
  4. Component-Based Approach: Routing is handled through components, making it easy to compose routes and navigation in a modular and reusable way.
  5. Handling Nested Routes: React Router allows the creation of nested routes, which enables a more organized and structured approach to rendering content. This is particularly useful for larger applications with a complex structure.
