Are you wondering what the much-hyped Progressive Web Apps are? Well, this blog is all you need to learn regarding the immensely popular Progressive Web Apps, or PWAs. It offers an in-depth tutorial on Progressive Web Apps (PWAs) and the advantages they have over conventional web apps.
Progressive web applications (PWAs) combine the best features of mobile apps with those of the web. They are gaining popularity among businesses across the globe because they eliminate the need for native app development, use less data, load quickly, and occupy less disc space than traditional apps.
There are a number of applications available for Android and iOS devices, but are they worth the space that they occupy on your device? If you are of the opinion that many of them aren’t, Progressive Web Apps PWA react in a way that is bound to attract you!
A study reveals that 53% of visitors leave a website if it takes longer than three seconds to load. In order to provide a web-based app-like user experience, progressive web applications are the best solution.
What is a Progressive Web App, or PWA?
Websites that are more like native mobile apps are known as “progressive web apps” (PWAs). It is by mimicking the look and feel of a native app that a PWA provides a seamless experience across the desktop, tablet, and smartphone. When making a progressive web app, one must use both web development and mobile app development techniques.
Here are a few examples of progressive web apps.
1. Twitter Lite
The consumption of data was reduced, page loads were sped up, and engagement was boosted thanks to Twitter’s progressive web app. The list of popular progressive web apps includes apps such as Starbucks, Tinder, and Facebook.
Trivago launched its own PWA in 2017, and this enabled Trivago to increase their clickthrough rates for hotel deals by 97%. Over half a million people have declared trivago.com to be their default hotel search engine, proving the feature’s massive popularity. PWA users who put the app on their home screen had 150% more engagement than those who used the prior mobile site (average of 0.8 repeat visits vs. two for PWA users).
It was Pinterest’s goal to expand internationally to encourage its first foray into the progressive web app space. They found out that just 1% of visitors signed up, logged in, or downloaded the native app due to the sluggishness and antiquated nature of their website. This prompted them to invest money in PWA, motivated by the belief that it had a good chance of increasing this conversion rate.
AliExpress is a well-known online marketplace where you can purchase just about everything, from apparel and accessories to electronics and even pet supplies and home appliances. After launching its PWA, AliExpress saw a 104 percent increase in the percentage of visitors who became paying customers.
The investment in Safari’s mobile web also increased conversion rates by 82%, and this proves how PWAs can transform the face of any business.
In 2015, Flipkart, India’s largest online marketplace, temporarily disabled its mobile website in favour of an app-only strategy. Flipkart found it challenging to provide a user experience on par with the speed and novelty of their mobile app. But once the company realised its strengths and weaknesses, it went ahead to introduce new features that made the mobile web fast and offline-capable. This enabled them to garner users, leading to a significant increase in mobile web use. Here’s a summary of the results.
• Increased re-engagement rates by 40%
• Increase in effectiveness by 70%
• Three times less data usage
How does a PWA function?
PWAs operate neither like websites nor like native applications. It therefore becomes crucial to learn how a PWA can benefit a company. When a user starts a PWA, it will automatically begin downloading any available updates, and once the web app is updated, users will automatically get to enjoy the new features.
With PWAs, websites can provide features such as the ability to work offline, push notifications for new data, and so on. This gradual revelation of functionality is dependent on the user’s device and whether it works on the same code base.
Progressive Web Apps vs. Native Apps: A Comparative Study
In contrast to traditional mobile apps, progressive web apps are web-based yet nevertheless provide a high-quality user experience. With a PWA, one can expect faster page loads and lower data consumption.
However, a native app is a mobile programme that is meant to work in conjunction only with a particular operating system. To consider an example, even though the functionality is similar, Java is compatible with the Android operating system, while Object C is compatible with the iOS operating system.

What Characterizes a Progressive Web App?
Progressive web applications are characterised by the following characteristics:
Functions consistently across all major web browsers
adaptable to the screen size of its viewer, whether they’re using a smartphone, laptop, or tablet, irrespective of the size of the screen.
3. Readily accessible:
Discoverable through search engines. In light of Google’s recent updates to its search algorithm, PWAs have a better chance of rising in the search results.
4. Independent of internet access:
capable of functioning even with intermittent or slow internet connections and allowing for partial or complete use even when no network is available (through caching).
5. App like:
The user interface and features are quite similar to those of other popular mobile apps.
It supports “HTTPS,” which means the data you send and receive will be encrypted.
Push API, a notification mechanism, is available for re-engagement.
8. Updated regularly:
A service worker updates the script on regular intervals, ensuring that the material is always fresh.
It is possible to send a link to your friends and family to access your PWA.
Users need not download it from the App Store or Google Play, and they can just add the app’s icon to their home screen.
Various Technologies That PWAs Use
A progressive web app is the result of several technologies working together to create something that is both novel and intuitively distinct from conventional web apps and even single-page applications. Below is a list of some of the popular technologies used by PWAs:
It is what lets Progressive Web Apps provide their information, display mode, icons, and other app-specific settings.
2. Service Worker:
With the help of a service worker, PWAs can function even when they don’t have access to the internet. Its service worker facilitates cache management and prevents any hindrance when it comes to the offline experience.
3. Database libraries:
PWAs need a persistent data storage mechanism, just like mobile apps. PWAs can make effective use of data storage with the support of non-relational databases such as PouchDB and RxDB.
Advantages of Progressive Web Apps
PWAs have the potential to provide a high-quality user experience that caters to the demands of modern consumers. Here are the advantages of using a progressive web app:
1. Rapid loading:
PWA pages load quickly because only necessary resources are downloaded at the time of the first request. The service worker caches more resources, making page transitions even quicker.
2. Increased interaction:
User interaction has been enhanced thanks to the service worker’s push notifications.
3. Reduced storage:
It is possible to use a PWA directly in the browser without the need for downloading and installing anything. It has a low footprint and can be used on almost any device, and a suitable example of this is Twitter’s progressive web app (PWA), which is just 600 kb.
4. Reduced data consumption:
Very little bandwidth is used owing to the fact that PWAs rely mostly on static content.
5. Offline support:
Creating an app is more cost-effective when you simply have to write one set of code instead of dedicating separate teams for creating an Android app and an iOS app.
7. Reduced time consumption:
Development time is reduced since just one version has to be developed rather than two.
Typical Applications of PWAs
There is a resonance between Progressive Web Apps and other apps. Therefore, it is important to define your requirements in order to determine whether you desire a progressive web app, a website, or a native mobile app. So, when should you go for PWA development? Here are a few instances when you should consider developing a PWA:
- When you care most about storage, loading speed, and minimising data use.
- When you prioritise online and mobile development.
- When you are set on developing a native app and have even planned for ASO.
- When Bluetooth is enabled, wireless connections are not a requirement.
- When you do not wish to limit your focus to Apple products.
To-Do List for Progressive Web Apps
Consistently give these factors your full attention while developing a progressive web app:
- Offline assistance
- Push Notifications
- Pixels that may be rendered as vector graphics
- An appropriate icon size in PNG is 144 pixels by 144 pixels.
- Providing universal access to the World Wide Web while adhering to WCAG 2.0 norms
- Compatible with search engines
- Functions very well with any input devices such as a mouse, keyboard, and the like.
- A well-organised software architecture that helps reduce overall technical debt.
Is the PWA strategy dependable?
In order to arrive at a well-performing PWA, the first step you ought to take is that of developing a thorough plan. Always remember that the consumers’ interaction with the programme takes place outside of a web browser. Users expect a higher degree of functionality when a browser’s UI is eliminated.
The first step in any PWA plan should be to create a state-of-the-art website that follows a number of best practices.
- Flexibility and interaction in layout
- Compact nature
- Enhanced accessibility
Instead of relying on one’s browser as a crutch, one should gear up to meet the aforementioned features. The absence of standard browser features such as back and refresh buttons is a significant disadvantage of PWAs.
Are PWAs suitable for mobile use?
What we refer to as “progressive web applications,” or PWAs, is a combination of the best features of both traditional web pages and native mobile apps. However, PWAs stand out because of the fact that they provide the same level of customer service and can be downloaded and installed on mobile devices just like native apps. These apps offer their users a lightning-fast web experience on desktop computers as well as their mobile devices. Moreover, customers can accommodate additional capabilities, such as increased offline content storage, by installing a PWA.
Will PWAs supersede native apps?
Although PWAs are better than native mobile applications, they may not always be the right choice as they lack freedom in terms of the user experience when compared to a native mobile app. An illustration of this could be the fact that PWAs are not always effective at sending push notifications to iOS and Android devices, thereby affecting user engagement.
Should one implement PWA?
If you wish to both improve the performance and user engagement of your website, it is definitely time to switch over to a PWA. Since PWAs resemble traditional websites in that they enjoy the same search engine optimization advantages, they can boost the traffic on the website in no time. Their adaptability across a range of devices makes it easier for customers to engage with them.
Is support for progressive web applications available in all browsers?
While Firefox on Android devices fully supports PWA features, Chrome, Apple Safari, and Microsoft Edge partially support this feature. However, the desktop version of Firefox does not support a PWA framework.
