What Is Progressive Web App And Why It Is Important?

A progressive web app (PWA) is an application that delivers an app-based interface to users. It uses modern web capacity to meet certain requirements and results in apps that can be accessed via URLs. Such apps are indexed on search engines as well as installed on servers. In layman’s words, PWAs combine the best of websites and apps. According to Alex Ruxwell, the expert who coined the term, “PWAs are just websites that took the right vitamins”.

To understand what a progressive web app is capable of, it is important to break down the meaning and functions of PWA. The following features also act as a criterion for something to be categorized as PWA. Therefore, Progressive Web App is a quantum of the following characteristics:

Progressive: a powerful tool that operates well irrespective of the browser choice of the user. It is unfazed by differences in types of users as it “enhances” itself after every time a user operates it.

Responsive: This suits the need for any gadget/hardware-whether it is a desktop, a laptop, phone, tablet, or any other medium that will be launched in the future.

Independent in Connectivity: PWA is supposed to be designed in such a way that it can operate offline or on slow-speed networks as well. Therefore, it is not dependent on the nature or speed of the user’s connectivity to the internet. PWA is the manifestation of the idea that apps should be able to run even without an offline server by caching data for visual content.

App Based: Any user can switch to an app-like view or interface on PWA because it offers them an option in the form of an “app shell model”. The app shell model enables the design to be split in terms of functionality and content. Thus while the application content will remain the same, it is possible to change or alter the functionalities of the application.

Safety: Every PWA provides a secure server, the green signal that users can see on top of their browser in the form of a green lock. In technical language, PWA has to be served via HTTPS to firewall against snooping or content tampering.

Up-To-Date: Due to cache-storage ability, PWAs are always upgraded timely.

Re-Engagement: With the help of elements like options to enable push notifications, PWAs can help users be engaged and notified on a custom basis.

Shareable: No complicated installation is required for users when they want to operate PWA, all they need to do if they want to share PWA is to share the URL.

Identifiable: PWAs are easily discoverable as worker registrations allow them to be indexed in search engines, and consequently, search-worthy on search engines.

Convenient to Keep: Users can just keep their preferred PWA on their home screen and they do not need to access any kind of app store to have access to them.

As the user constructs a relationship with the app after using it time and again, the PWAs have inherent programming to store the cached data, making it possible for the app to load even on slower connections.

Think of PWA as a Ferrero Rocher chocolate-the hazelnut is the content you want to use, the chocolate around the core is your visual aspect of the website-like presentation and finally, the outermost wafer and chocolate layer is the JavasScript. The layer outside can vary in terms of its surface or even color depending on the way the browser uses it.

Approaches to Progressive Web Apps – PWA Decoded

PWAs support is ever increasing. All different platforms and all major companies are choosing to make PWA versions of their websites. But how exactly does PWA work?

The world wide web is a relatively independent system that is bound to no operating system. Why then do users prefer to use native apps on the web for practically everything? It is due to the seamless and smooth interface of apps and the easily maneuverable experience along with engagement that native apps offer.

Thankfully, it is possible to combine ease of access to the internet and the smooth experience of native apps. For e-commerce websites, your ecommerce website development company uses all relevant approaches to combining these two spheres.

This way, PWA is an app that one can access directly from the web and are easy to run at the same time. These apps that people operate have notifications and are installable, and faster than native apps or web apps.


1. What is a Service Worker?

A service worker is a Javascript file that operates separately from the leading browser network in the background and intercepts all requests regarding the network, caches data, and gives a building block for many APIs like push notifications, caching, and background refresh.

In simple terms, the service worker is the element responsible for giving functionality to an app even when it is closed. It enables the app to be offline-first.

2. What is The use of HTTPS?

Hypertext Transfer Protocol Secure is just the tool that makes HTTP communications secure by using SSL or TLS encryption. The element of HTTPS as mentioned before makes the PWA function securely.

3. What is Web App Manifest?

Webapp Manifest is the tool that enables visual elements of the app. It gives information and data about the way an app should look on the home screen, on the web, and other mediums. It is used to add themes in terms of colors and gradient, it adds icons for the home screen, and many other visual functions.

In other words, Webapp Manifest makes apps look friendlier with themes and icons. It can be installed with the help of a JSON file.

4. What is the use of Push Notification and Background Refresh?

PWA servers deliver push_ notifications to service workers which communicate and update the current state or even display a message to the user. This function runs independently in the background and thus works when the app is closed too.

5. Are There any Additional tools an eCommerce Development Agency can use?

PWAs can be worked on with some extra standards for better output. All the competent ecommerce website developers use them. Here are some of the tools:

a) Lighthouse and PWA Checklist

Lighthouse is a tool for checking the quality of web pages as it takes audits of performances, practices, accessibility, and more criteria for PWA. It checks if your app meets the benchmarks and ranks how good of a PWA it is.

PWA Checklist is by Google and it lays down all suggestions to fill the gaps in your web app. It gives general guidelines to adhere to and some improvement techniques to fix issues.

b) Storage

Storage is a crucial aspect of PWA and as per experts, one must use the Cache API for URL resources for storage. In the case of any other data, IndexedDB should be used. These systems store all data from the browser and work as a high-performance API.

c) Caching

Caching API in your PWA can let you stock up on responses that are keyed by request. This way, the content can be loaded directly from the cache in the eventuality of a poor connection. Only necessary data is loaded.

6. Why Should my Company Depend on PWA?

PWAs offer a clean method to engage the users of the app and encourage them to use the application your company puts up. Owners of PWA have access to a bigger user group that increases the size of the audience. PWAs are the way to go about web services for all kinds of MNCs as well as Small. Medium and micro businesses.

It is also a noted fact that most search engines display PWA first on the results page as they offer a sophisticated surfing experience.

PWAs provide advanced platform features and are highly dynamic. Therefore, it is always recommended to upgrade your website or optimize it into a PWA so that you can enjoy the benefits of having an edge over your competitors in the market.
