}
}
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 class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"><img src={logo} className="App-logo" alt="logo" /></a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav">
<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.
http://127.0.0.1:3000
