Core Features of Progressive Web Applications

The demand for flexible and user-friendly digital solutions is increasing all the time. PWAs are essentially the highest level of digital platforms since they so skillfully fill in the gaps and constraints that were previously connected to native mobile apps and regular web sites. Their unified, effective, and user-focused design comes from a variety of aspects that we have briefly mentioned. 

We will now take a more detailed tour, revealing the complex web of features and attributes that really capture the essence of Progressive Web Applications.

Offline accessPWAs are notable for their ability to work even when there is no internet connection. This is accomplished through the use of “service workers,” which cache important app pieces. This means that users can continue to access content, browse pages, and even accomplish work without being interrupted by a loss of connectivity.
Push notificationsPWAs, like mobile apps, may send notifications that inform you of new messages, changes, or events. Push notifications are messages that appear on a user’s smartphone even when the app is not active. This function helps in re-engaging consumers, keeping them up-to-date, or encouraging them to take part in a specific activity.
Fast load timesThe essence of the user experience is speed. PWAs are meant to load quickly, allowing consumers to access content without having to wait long. This is accomplished through the use of effective caching, streamlined content delivery, and optimized code. As a result, the experience is smooth and lag-free, comparable to native apps.
Responsive designPWAs are designed to fit every screen size, whether it’s a smartphone, tablet, desktop, or even a wristwatch. This adaptable design ensures that the app’s layout, pictures, and features alter automatically to deliver the best viewing experience possible, regardless of device.
Home screen installationWhile PWAs are accessible through a browser, users may ‘install’ them on their device’s home screen. This doesn’t require installing them from an app store, but rather the addition of a shortcut icon. This functionality makes accessing the PWA as simple as touching on the icon of a native app, encouraging regular use.
Safe and secureSecurity is essential. PWAs employ HTTPS to ensure that the material is not tampered with and that user interactions are private. Furthermore, the architectural design of PWAs provides fundamental security against typical web vulnerabilities.
Automatic updatesPWAs update themselves in the background, unlike traditional apps, which require users to manually update to the latest version. This ensures that users always have access to the most recent and secure version of the application with no effort.
Cross-platform capabilityPWAs are designed to work across multiple platforms. The experience is exactly the same whether you’re using an Android smartphone, an iOS tablet, or a Windows PC. This broad reach simplifies development and provides users with a consistent experience.

The PWA Impact: From big brands to our own benchmarks

Progressive Web Applications, or PWAs, are no longer just fancy terms used in business. Some of the top businesses in the world have incorporated these potent digital tools into their plans with ease, and the results have been revolutionary. Let’s take a look at two amazing success stories, Starbucks and Pinterest, before delving into OpenLMIS, our in-house initiative.


Starbucks, one of the world’s largest coffeehouse companies, recognized the need to improve its mobile ordering experience and created its PWA, which allows users to purchase beverages, identify nearby stores, and earn rewards.


Starbucks looked to create a one-of-a-kind digital experience without asking users to download and install a separate app. They wanted it to be accessible regardless of the network circumstances of their globally dispersed clients, some of whom live in areas with slow internet.


PWA evolved as a solution to Starbucks’ challenges. Starbucks enables users to explore their huge menu even in the absence of internet connectivity by including a PWA into their digital infrastructure. This offline functionality didn’t just allow customers to explore; it also actively engaged them by allowing them to customize their orders. This personalized ordering procedure became an essential aspect of the Starbucks experience. Furthermore, the PWA guaranteed that any offline modifications made by a user, such as changing their order, were instantly updated whenever they reconnected, ensuring a smooth, synchronized digital experience.


The switch to PWA technology generated positive benefits. Starbucks had an amazing doubling of daily active users. Furthermore, they witnessed a 65% increase in orders, with desktop users playing a substantial role, highlighting their PWA’s wide and consistent reach.


Pinterest, a well-known visual discovery engine, recognized the need to improve its mobile surfing experience. In response, the site launched its PWA, which provides users with faster access to pins, easier board management, and more engaging personalized content recommendations.


Pinterest, a giant in the visual content arena, faced a complex web of issues coming from its mobile platform. Their mobile landscape was slipping behind consumer expectations. This speed loss not only prevented engagement but also formed a bottleneck in enrolling new users, resulting in a substantial drop in sign-ups.


Like Starbucks, they saw the potential in utilizing this cutting-edge technology for a full redesign. The idea included more than just increasing speed; it also involved a more comprehensive upgrade of the user experience. They drastically lowered page load times and, for the first time, experimented with push notifications for mobile web users, which proved useful in re-engaging consumers. Along with these enhancements, they highlighted the creation of a fluid and interactive user interface.


The move to PWA bore significant fruit, mirroring the success stories we’ve seen with firms like Starbucks. Their user-generated ad revenue increased by 44%, while their core interactions increased by 60%. Perhaps most impressively, the once-stagnant new user sign-up measure was renewed, increasing by 50%.


OpenLMIS, an established open-source logistics management information system designed to improve the distribution of health products in countries with low incomes, saw an increasing need to maximize its online presence. The conventional OpenLMIS interface was unable to provide the necessary level of smoothness in light of the growing use of mobile devices in these countries.


The goals of OpenLMIS were straightforward: to offer consumers an identical experience regardless of the type of device they use, while at the same time staying under tight budgetary constraints. Taking advantage of native applications for many different devices would be an expensive and complex method of development. A flexible, affordable solution that wouldn’t compromise the user experience was urgently required.


The answer was the intentional integration of many state-of-the-art technologies. In order to provide a flexible, native-like experience across all platforms, OpenLMIS made the decision to rely more on Progressive Web Apps.

On the frontend, well-known frameworks such as React, Angular, and Vue.js stand out, each with its own set of characteristics for creating intuitive and performant PWAs.

The backend, on the other hand, should not be disregarded. It is critical for the overall performance of a PWA to provide seamless data flow, scalability, and robust server-side activities.

Next.js is an example of a full-stack framework which is built on React and provides an out-of-the-box efficient architecture for developing server-rendered JavaScript apps, easing the process of constructing PWAs. It combines frontend and backend development in a seamless manner, ensuring quick data management, server-side rendering, and an improved user experience.

Finally, the unique requirements of the project determine the selection of a certain framework. While frontend frameworks define the user experience and interface, backend systems and full-stack solutions such as Next.js ensure that this interface is backed by strong server-side support. The combination of these technologies, carefully selected depending on project objectives, is the foundation of effective, high-performing PWAs.

Development Best Practices for PWAs

We’ve covered the fundamental features, architectural complexities, and important tools of PWAs, as well as various best practices essential to their development. In this part, we aim to consolidate and expand on such practices, resulting in a more comprehensive picture. 

How can we apply what we’ve learned to create successful PWAs? The answer is in the following established best practices – guidelines that ensure our PWA is developed successfully, efficiently, and stands out in a digital sea of similarity. Let’s go over these useful practices, which are closely related to the previously discovered insights.

Prioritize performance and responsiveness

A quick and seamless user experience is essential. Remember how we talked about the need for quick load times earlier? User satisfaction is deeply related to performance, with even little delays causing declines in engagement.

Key strategies:

– Optimize images and assets: Images account for a sizable amount of the weight of a web page. You can assure speedy loading times and low bandwidth use by adopting modern formats such as WebP and ensuring assets are compressed and optimized.

– Lazy loading: This strategy ensures that only the content that is immediately required is loaded up front. Additional items, such as photos further down a page, are loaded only when they are visible to the user or are otherwise required. This significantly reduces initial page load times.

– Cache strategically with Service Workers: They run in the background, separate from your web app, and provide features such as push alerts and background syncs. More importantly, they may intercept network requests, cache or retrieve resources from the cache, and respond quickly.

Ensure offline functionality

The beauty of PWAs is their ability to function smoothly even in unstable network situations. PWAs can provide users with uninterrupted experiences by leveraging service workers, which brings us back to our prior concept of offline access.

Key strategies:

– Implement Service Workers for caching: They are essential for offline functioning as well as performance. Service workers ensure that your app stays accessible, even when the internet is unavailable, by caching assets.

– Dynamic content updates: If a user makes changes while offline (such as saving a draft or adding an item to a wishlist), make sure that when the PWA comes back up, it syncs and updates.

Engage users with push notifications

A crucial component, push notifications, serve as a direct route of communication with users. When utilized wisely, they can significantly boost user engagement.

Key strategies:

– Seek permission thoughtfully: It can be off-putting to bombard a new user with permission requests. Consider asking for permission after a user has completed a relevant activity, such as making a purchase or bookmarking an item.

– Craft notifications with care: A push notification should always be useful. Make sure it’s timely and relevant, whether it’s an update, a reminder, or a personalized recommendation.

Design with a mobile-first approach

Given that PWAs are intended to bridge the gap between standard websites and native apps, their design should prioritize mobile experiences, reflecting our previous ideas on responsiveness.

Key strategies:

– Responsive design across devices: Your PWA should adapt seamlessly to every device, tablet, smartphone, or desktop, guaranteeing consistent functionality and design.

– Optimize for touch: Touch interactions are the most common on mobile devices. This means that clickable items should be appropriately sized, and there should be enough space between them to prevent accidentally clicking. Smooth animations and transitions should be used to contribute to the app-like vibe.
