npm install bootstrap --save

here, we will import the bootstrap in the app.js file, so you can see the below code.src/app.js

import React, { Component } from 'react';
import 'bootstrap/dist/css/bootstrap.min.css';

class App extends Component {
  render() {
    return (
      <div className="container">

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

import App from './App';
import * as serviceWorker from './serviceWorker';

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

serviceWorker.unregister();

Step 4: Create react components

here in this step, we will create three components, like home, about, and contact. so you can see the below code.src/home.component.js

import React, { Component } from 'react';

export default class Home extends Component {
    render() {
        return (
            <div >
            <h3>Welcome To Home Page</h3>

                            <div className="errorMsg">{this.state.errors.txtFname}</div>
                        </div>
                    </div>
                    <div >
                        <label  for="txtLname">Last Name:</label>
                        <div >

                        </div>
                    </div>
                    <div >
                        <label  for="txtMessage">Message:</label>
                        <div >
                            <pre name="txtMessage"  id="txtMessage" onChange={this.handleChange}></pre>
                            <div className="errorMsg">{this.state.errors.txtMessage}</div>
                        </div>
                    </div>
                    <div >        
                        <div >
                            <button type="submit" >Submit</button>
                        </div>
                    </div>
                </form>
            </div>
        )
    }
}

Step 5: Set up the route inside the App.js

now, we load the header menu and set up the route inside the App.js file.src/App.js

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

import home from './home.component';
import contact from './contact.component';
import about from './about.component';
import logo from './logo.svg';
import './App.css';

class App extends Component {
  render() {
    return (
      <Router>
        <nav >
          <div >
            <div >
              <button type="button"  data-toggle="collapse" data-target="#myNavbar">
                <span ></span>
                <span ></span>
                <span ></span>                        
              </button>
              <a  href="#"><img src={logo} className="App-logo" alt="logo" /></a>
            </div>
            <div  id="myNavbar">
              <ul >
                <li><NavLink exact activeClassName="active" to={'/'}>Home</NavLink></li>
                <li><NavLink activeClassName="active" to={'/about'}>About</NavLink></li>
                <li><NavLink activeClassName="active" to={'/contact'}>Contact</NavLink></li>
              </ul>
            </div>
          </div>
        </nav>
        <Switch>
            <Route exact path='/' component={ home } />
            <Route path='/about' component={ about } />
            <Route path='/contact' component={ contact } />
        </Switch>
      </Router>
    );
  }
}
export default App;

Step 6: Run React js application

If you want to run the application then you can follow the below command. if you any change in your app then use the npm run build and after you can run the application.

cd my-app
npm start

Now we will run our application using the below Url in the browser.
