React JS BrowserRouter NPM - Shell/Bash

Introduction

React JS is a popular JavaScript library that allows developers to create dynamic user interfaces. One of the key features of React is its support for client-side routing. With client-side routing, web apps can update the URL without actually navigating to a new page. This allows for a smoother, more responsive user experience.

One way to implement client-side routing in your React app is to use the BrowserRouter component. The BrowserRouter component is a higher-order component that wraps your entire app and provides the functionality for client-side routing.

In this guide, we'll walk you through the steps to install and use the BrowserRouter component in your React app.

Prerequisites

Before we begin, make sure you have the following installed on your system:

• Node.js
• npm (Node Package Manager)
• React JS

Installation

To install the BrowserRouter component, open a terminal window and navigate to your project directory. Then type the following command:

npm install react-router-dom

This command will install the latest version of react-router-dom package, which includes the BrowserRouter component.

Usage

To use the BrowserRouter component in your React app, you need to import it and wrap your entire app inside it. Here's how you can do it:

1. Open your app's main index.js file and import BrowserRouter:

import { BrowserRouter } from 'react-router-dom';

2. Wrap your entire app inside the BrowserRouter component:

ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById('root')
);

Note that in this example, we're assuming that your app's main component is called App.

3. Create routes for your app. You can do that either by creating a separate file for your routes and importing it into your app, or by defining them inside your main component. Here's an example of how to create a simple route inside your main component:

import { Route } from 'react-router-dom';

function App() {
  return (
    <div>
      <Route exact path="/" component={Home} />
      <Route path="/about" component={About} />
    </div>
  );
}

In this example, we have two routes defined: one for the home page (path="/") and one for the about page (path="/about"). Note that the exact keyword is used for the home page to ensure that only that route is matched.

Conclusion

By using the BrowserRouter component from React Router, you can easily implement client-side routing in your React app. In this guide, we showed you how to install and use the BrowserRouter component, as well as how to define routes for your app.
