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. One such solution is Progressive Web Apps. PWA technology has 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 on 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. Seeing such wide benefits of PWA, every enterprise software development company is leveraging this technology to build high-performing solutions for their clients, especially e-commerce and advertising ones who need to deliver a better shopping experience to customers every time they visit their website. 

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 the 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 with its appearance much similar to that of native apps. It provides the metadata of the application including icon, application name, launch URL, background color, 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 save offline user-generated data and minimizes data traffic.


A PWA requires an icon that should be approximate 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. 


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 the 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. The 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 are 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, a marketing site, or a shop. And, offer the best of both worlds – URLs from the www, offline access, push notifications, and deep linking.

Boosted ROI 

Companies have experienced significant improvement in their revenue, profits, user engagement, and lead conversion metrics after implementing PWA solutions. In case of Pinterest website, their user engagement and ad click-through rate were increased by 50% after PWA implementation. This was much better than their mobile application. The guarantee of an enriching user experience in PWA assists you in reaching more customers and keeping them engaged. 

Platform Independence 

With PWA in action, you don't need to worry about your website/app performance and accessibility issues. PWAs deliver native-like experiences and can be accessed from any device. It allows the user to install the app directly from the internet without worrying about the app store download. PWAs are always up to date even when there is no internet access. Users don't have to worry about installing updates on different devices. 

Search Engine Friendly

PWAs are essential websites so they are easily accessible on the internet via search engines. This makes them more discoverable and provides a decent edge above native applications which lags behind when it comes to online discoverability.
