Angular Bootstrap Hello World App – Sample Code

0

In this post, you will learn about how to get your Angular App to use Bootstrap CSS and Javascript libraries for creating some great UI.

The following are the steps for creating the Angular app with Bootstrap CSS and Javascript:

  • Get started by creating a Hello World App. Check out the post, Angular 7 Hello World App for greater details.
  • Go to the folder consisting of index.html. This is the folder src within the project folder.
  • Place the following code within the head tag. The code primarily represents the Bootstrap CSS file and a viewport meta tag for responsive pages.
     <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
     <!-- Bootstrap CSS -->
     <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
    
  • Place the following code within the body tag. The code represents Javascript libraries of JQuery and Bootstrap.
     <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>
     <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js" integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49" crossorigin="anonymous"></script>
     <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>
    </body>
    
  • Test the Angular Bootstrap App: Test the app by placing the class as the container within body tag in index.html. This would result in changes on the page. If you do not want to load Angular App within Bootstrap container class, remove class=”container” from the body tag in index.html.
  • Using Bootstrap CSS and JS Components: Once done with above, one could easily use Bootstrap CSS and JS components within any Angular component by placing the appropriate Bootstrap code snippet in App components’ CSS or HTML file.
  • Jumbotron Template for Homepage: Test Bootstrap with the following Jumbotron template by placing the following code within app.component.html file. Alternatively, get the code from the following Jumbotron page from Bootstrap Website
    <nav class="navbar navbar-expand-md navbar-dark fixed-top bg-dark">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
    </button>
    
    <div class="collapse navbar-collapse" id="navbarsExampleDefault">
    <ul class="navbar-nav mr-auto">
    <li class="nav-item active">
    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
    </li>
    <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
    <a class="nav-link disabled" href="#">Disabled</a>
    </li>
    <li class="nav-item dropdown">
    <a class="nav-link dropdown-toggle" href="http://example.com" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a>
    <div class="dropdown-menu" aria-labelledby="dropdown01">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
    </div>
    </li>
    </ul>
    <form class="form-inline my-2 my-lg-0">
    <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
    </form>
    </div>
    </nav>
    
    <main role="main">
    
    <!-- Main jumbotron for a primary marketing message or call to action -->
    <div class="jumbotron">
    <div class="container">
    <h1 class="display-3">Hello, world!</h1>
    <p>This is a template for a simple marketing or informational website. It includes a large callout called a jumbotron and three supporting pieces of content. Use it as a starting point to create something more unique.</p>
    <p><a class="btn btn-primary btn-lg" href="#" role="button">Learn more &amp;raquo;</a></p>
    </div>
    </div>
    
    <div class="container">
    <!-- Example row of columns -->
    <div class="row">
    <div class="col-md-4">
    <h2>Heading</h2>
    <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
    <p><a class="btn btn-secondary" href="#" role="button">View details &amp;raquo;</a></p>
    </div>
    <div class="col-md-4">
    <h2>Heading</h2>
    <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
    <p><a class="btn btn-secondary" href="#" role="button">View details &amp;raquo;</a></p>
    </div>
    <div class="col-md-4">
    <h2>Heading</h2>
    <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
    <p><a class="btn btn-secondary" href="#" role="button">View details &amp;raquo;</a></p>
    </div>
    </div>
    
    <hr>
    
    </div> <!-- /container -->
    
    </main>
    
    <footer class="container">
    <p>&amp;copy; Company 2017-2018</p>
    </footer>
    

    In addition to the above code placed in app.component.html file, place below code in the styles.css file found within src folder.

    body {
      padding-top: 3.5rem;
    }
    
  • Check whether the homepage showed up the Jumbotron template.
