A progressive web app comes with lots of functionalities that give them an edge over regular web apps or native apps. We are going to discuss the key attributes of progressive web apps below.


Just like you install a native app on your mobile device or desktop, you can also install a progressive web app on your device. In fact, installing a PWA is much easier than installing a native app because it doesn’t have a complicated installation process. The installation of the PWA eliminates download time in a browser and it is easily accessible from a device’s screen. Hence, you can use a PWA like a native app on your device while taking all the benefits of web apps.

App-like experience

This is what makes a PWA unbeatable because it runs in a separate browser window and in full-screen that offers the look and feel of the native apps on your devices. These apps are built on the application shell model and do minimum refreshes making them an exceptional solution for businesses that combine the best of both web apps and native apps.


Originally a PWA is a website that got the appearance and features of an application. Consequently, it is easily discoverable in the search engine results pages. And, this is one of the biggest advantages of progressive web apps. They are exposed to far more audiences than native apps.


The linkability of a progressive web app is one of its principal advantages that makes progressive web app framework development successful. Since every PWA has a URL that one user can use to share with others as well as bookmark the app. The app can retain or reload its state when sharing or bookmarking the app.


As we know PWA ‘P’ stands for progressive which means a PWA harnesses all the attributes of the users’ device or browser, augment progressively, and must function on all devices seamlessly. Hence progressive attribute of a PWA makes it an advanced web app with some excellent functionalities.

Safe and always fresh

Progressive web apps are served through HTTPS. So, these web apps are very secure. Further, they always remain up-to-date because they are updated automatically and load fresh content every time they run.

Connectivity independent

A progressive web app can run in a low connection or even without an internet connection because it caches the content that was loaded on the first launch. So, it offers an offline experience to users.


One more key advantage of PWAs is that these apps possess many device-related features and one such example is push notifications. They allow retailers to send notifications to ensure to re-engage users with the app.

What are the components of a PWA?

Every progressive web app has a technical structure that works behind the scene to make such an app operable. You can create outstanding PWAs today by using bare web technologies. You can also use a progressive web app framework like AngularJS, ReactJS, Ionic, etc to build a robust PWA. In this section, we will focus on the most important components of a PWA and discuss them.

Service Worker

This component works like a middleman between the app/browser and the network/server and processes network requests (receive requests from the browser and forwards to the server, similarly, receives a response from the server and sends to the browser). Service workers are behind caching of the content when a PWA loads for the first time. So, it offers offline functionality for users. Also, due to the caching pages load very speedily. Push notifications are also a task that is performed by the Service Worker. It also does background data synchronization.

Manifest File

It is one of the most important components of a progressive web app that contains a lot of important information about your app. This file is saved as manifest.json and contains metadata related to a PWA. This data includes the app’s name, icon, launching URL, and more. With the use of the manifest.json file, developers can control the display aspect as well as the appearance of a progressive web app.

Application Shell

It is the requirement of HTML, CSS, and JavaScript that powers a user interface. While a native app includes an application shell in its distributable, websites usually request this over the network. Progressive web apps fill up this gap between websites and native apps by loading the application shell’s assets and resources in the cache of a browser.

Benefits or progressive web apps

The following are some benefits of using a PWA for your business.

Better user adoption

PWAs are lightweight and easy to install as well as offer an app-like look and features, so more users can adopt these apps as compared to native apps.

Reduced development cost

High-performance apps

Progressive web apps are way better than native apps when it comes to performance. This is because PWAs can load almost instantly due to caching of data.

These are just a few benefits of what a progressive web app can offer to both businesses and end-users. However, all of these benefits add value to a business and help them get an edge in the market over competitors. From connectivity to speed, PWAs are quite an attractive alternative for resource-intensive and slow native apps that cannot offer a top-of-the-line user experience.
