Introduction to building a responsive web application

Responsive web applications have become a necessity in today’s digital landscape. With users accessing websites and applications on various devices, it is crucial for you to create experiences that seamlessly adapt to different screen sizes and orientations. In this section, we will provide an overview of responsive web applications and explore why they are essential in delivering a satisfying user experience.

Why responsive web applications matter

In the past, websites were primarily designed for desktop computers with fixed screen sizes. However, with the rapid proliferation of smartphones, tablets, and other mobile devices, the landscape of web browsing has dramatically changed. Users now expect websites and applications to be accessible across a wide range of devices, from large desktop monitors to small smartphone screens. Here is an example of a broken website on mobile:

Introducing our responsive web application project

Our project focuses on creating a responsive landing page that effectively showcases a Software as a Service (SAAS) product. The landing page consists of several key sections, including the header, hero, features, testimonials, pricing, and footer. Each section is strategically designed to engage visitors and drive conversions, whether by turning them into customers or capturing them as valuable leads. Let’s have a look at the following sketch:

Figure 14.2 – Project initial sketch

Based on the sketch, let’s examine the purpose of each section:

• Header: The gateway to our application, the header, will feature a clean and intuitive navigation menu, ensuring users can effortlessly explore the various facets of our landing page.
• Hero: Our hero section will be a visual delight, instantly grabbing attention with compelling imagery and a succinct message that communicates the essence...

Creating the layout of the website

Once we have the initial idea for our website, it becomes relatively straightforward to transform those sections into Angular components. Let’s have a look at the following transformation:

Figure 14.4 – Breaking down sections into Angular components

As depicted in the figure, each section is distinct and can be readily mapped to an Angular component. For instance, the header section can be assigned to header.component.ts. By following this approach, we can establish the following code structure as an illustrative example:

// app.component.ts
<primebook-header />
<primebook-hero />
<primebook-features />
<primebook-testimonials />
<primebook-footer />

Each selector represents the corresponding section in our sketch or design.

It’s pretty simple to get started to create those components by running the following command:

primengbook$ ng g c header --inline-template...

Starting to develop the website

So far, we’ve laid out the blueprint for our responsive web application. Now, let’s dive into the implementation details of each section. Remember, our goal is to create a seamless and visually appealing experience using Angular, PrimeFlex, PrimeIcons, and PrimeNG components.

Prerequisites

Before getting started, make sure that you have everything configured in your project such as primeng, primeflex, and primeicons. If not, you can run the following command:

npm i primeng primeflex primeicons

After that, check that your styling and theming are updated. Here is an example of a styles.scss file:

// src/styles.scss
@import 'primeflex/primeflex.scss';
@import 'primeng/resources/themes/lara-light-blue/theme.css';
@import 'primeng/resources/primeng.css';
@import 'primeicons/primeicons.css';

The provided code imports style files from different libraries. By importing these files, you are...

Deploying the responsive web application

Congratulations! You’ve successfully built a responsive web application using Angular, PrimeFlex, PrimeIcons, and PrimeNG components. Now, it’s time to share your creation with the world. Deploying a web application involves several crucial steps, from preparing the project for production to choosing the right deployment platform. Let’s explore each of these aspects to ensure a smooth deployment process.

Getting the project ready for production

Before deploying your web application, it’s essential to ensure that everything is optimized and ready for production. Here are a few key steps to follow:

• Optimize assets: Make sure to optimize your images to reduce their file size and improve loading times. You can use tools such as image compressors to achieve this. Here is an example of how to serve different images in different screen sizes:

  <picture>
    <source srcset="image-small.jpg...
