Progressive Web Apps: Why Companies Should Invest in PWA Technology

Introduction

Improving web experience on mobile devices has always been a tough task for programmers. But these coders always come up with innovative ideas and software solutions to offer amazing user experience across several verticals.

In today’s time, it is not only about meeting the specified requirements, but exceeding the limits and going beyond market demands to remain ahead in the game.

Progressive Web Apps (PWA) have brought a huge digital transformation in the software development industry. It has taken the web experience on mobile to the next level by giving an app-like experience to users.

Doesn't it sound too good to be true? Yeah!!! Let’s learn how it all became possible.

Although the PWA technology is still new to many, some early adopters are getting a very good response from users.

PWA comes with all the features you love to have in your site including offline capabilities, fast speed, easy updates, web push notifications and the rich functionality of a traditional web page. It offers a combination of mobile sites and native apps opening doors to a highly dynamic interface that exceeds conventionality. This enables users to interact easily across all channels, even in case of low Internet connectivity.

On the whole, it has a wider reach, very economical and keeps the users engaged on par with the best native apps.

What about progressive web apps and what’s the deal with it?

In 2015, Google introduced the term Progressive Web App (PWA). This is a type of application software that gives its users an app-like experience by using the latest web capabilities. It is built using popular programming languages including CSS, HTML, and JavaScript.

A quote from Alex Russell (Senior Staff Software Engineer at Google) can simplify the above definition,

Progressive Web Apps are just websites that took all the right vitamins.

In nutshell, PWA is a simple website that comes with some enhancements and offers certain functionality (mainly associated with native applications) and gives user the ability to:

  • Install it on a mobile home screen
  • Offline access
  • Push notifications
  • Background synchronization

And so much more.

Key Components of Progressive Web Apps

A number of key components support the functionality of Progressive Web App Framework and make these apps so special.

Web App Manifest

The web app manifest is the building block of progressive web apps that notifies the browser about your web app. It is a JSON file that provides the PWA apps its appearance much similar to that of native apps. It provides the metadata of the application including icon, application name, launch URL, background colour, app configuration data, and many other essentials.

For instance, imagine what will happen if you link to the manifest file in your index.html? This will allow the browser to detect that link and load the resource.

Service Worker

Service Worker is the backbone of PWA app development that allows web apps to manage network requests and multiple caches, saves offline user-generated data and minimizes data traffic.

ICON

A PWA requires an icon that should be approximately 144×144 large in size and in PNG format. This icon appears in the apps tray or on the home screen and a user launches the app with a simple tap. 

HTTPS

PWA apps are served through a secure HTTP connection. This is the only way to use the application.

Why build a Progressive Web App?

Because It Is Highly Responsive

Whether it is a desktop, mobile, laptop or tablet, PWAs can fit within any device. With its highly responsive feature, PWAs can automatically adjust the layout as per the device.

No Need To Worry About Security

PWAs are served via HTTPS. They are tamper-proof and cannot be vandalized. Hence, they offer better security when compared to traditional web apps.

Most Reliable

In spite of network flaws, progressive web apps are reliable as it offers offline access. Service worker, one of the key components of PWAs, makes it reliable. With PWA, a popular e-commerce app on internet in Nigeria named Konga managed to reduce the usage of user data by 92%.

It Is Always Up-to-date

With a service worker update process, you always get an updated version. User doesn`t need to visit the app store as there is no app store that serves as a mediator for updating/downloading the app. Hence, the app will be updated automatically as soon as it is updated from your end.

Higher User engagement

The link-adding feature of PWA allows the application to be cached easily and direct access right from your home-screen.

Oh It's Shareable

This app is easy to install and can be shared with a link or URL.

You Get Offline Access

Service workers is the keystone of PWA apps as it empowers content caching, offline functionality, push notification, and background updates. This means users get offline access to a previously visited website.

So now we can say a PWA may replace the traditional website very soon. It could be anything including a blog, marketing site, or a shop. And, offer the best of both worlds – URLs from the www, offline access, push notifications, and deep linking.

Final Thoughts!!!

With the above read, you can see how amazing PWAs can be. They are reliable, effective, fast and support offline mode. It enables you to improve the user experience of any traditional web app by adding a service worker and web app manifest file.

Having PWAs means you don’t need to develop apps separately for Android and iOS. You can also improve any mobile web property via progressive web apps and somehow eliminate the need for several “vanity” native apps that exist currently. They are cross-platform by default and comparatively economical to build.

Hence, to cut short, PWAs are excellent alternatives to mobile applications. So, it’s high time to integrate this powerful technology into your ecosystem.
