React is a JavaScript library for creating user interfaces based on UI components . And, Bootstrap is a CSS framework for creating responsive applications. Here, in this blog post we will discuss how to use Bootstrap in our React applications .

From the official guide

React-Bootstrap is a complete re-implementation of the Bootstrap components using React. It has no dependency on either bootstrap.js or jQuery.

First, let us create a new react project using the command:

npx create-react-app react_bootstrap_navbar


Then add few new components to the project. We will create a new folder called components and add three components: Home, About, Contact .

Now, we will be adding some content inside those three components .

const Home = () => {
    return (
        <h1>Home Page</h1>
    );
}

export default Home;

Similarly add some texts to About and Contact components .

In App.js file, let's import all three components.

 javascript
function App() {
  return (
    <div className="App">
        <Home />
        <About />
        <Contact />
    </div>
  );
}

In order to install the React Bootstrap npm package we can simply go to terminal and use the command :

npm install react-bootstrap bootstrap@5.1.3

After that we need to import bootstrap.min.css file in index.js or App.js file .

import 'bootstrap/dist/css/bootstrap.min.css';


We are now ready to use all the features of React Bootstrap .

Let us create a new component called Navigationbar.js and add the following code which will be responsible for creating our navbar .

)

Let's understand some of the components and props from the above code:

• Navbar component wraps the entire component .
• expand prop allows us to collapse the navbar at given breakpoint and we also need to add collapseOnSelect prop .
• Navbar.Toggle and Navbar.Collapse helps to get the mobile friendly navbar .
• collapseOnSelect prop works only if we add eventKey prop for NavLink item .

Now, we will install React Router library for building functioning navigation routes .

npm i react-router-dom@5.3.0

In App.js file, let us import BrowserRouter (aliased as Router) , Route and Switch from React Router .

import {BrowserRouter as Router, Route, Switch} from 'react-router-dom';

Moving on to our App.js file, let's add corresponding routes to the components.

function App() {
  return (
    <div className="App">
        <Router>
            <Navigationbar />
            <Switch>
                <Route exact path='/' component={Home}/>
                <Route path='/about' component={About}/>
                <Route path='/about' component={Contact}/>
            </Switch>
        </Router>
    </div>
  );
}

Here we are using Switch component which will render our components only when path will be matched .

Here's how our navbar looks on the desktop screen :

This is how the navbar looks on small screen devices :
