Progressive Web Apps: Building the Next Generation of Web Applications

Progressive web applications (PWAs) are the “hot tea” in the digital world right now for all the good reasons. They are the baby of a high-functioning website and a user-friendly mobile app. 

They deliver a smooth and rich user experience that everyone, especially Gen Z, loves. 

Compelling statistics, PWAs are not only capable of loading under 2 seconds faster than traditional websites, but they also boost remarkable data efficiency. For example, Jumia’s PWA users consume 80% less data during their initial transaction compared to the traditional application. 

This mixture of speed and efficiency directly translates to improving the user retention & conversion rates, with some companies reporting 36% higher conversion rates with PWAs compared to traditional applications & a 50% lower bounce rate. 

Consequently, many employers are actively searching for candidates with Progressive web application development skills to meet the ever-evolving requirements. So, you can forget about the slow, old-school websites. PWAs are the future – an avenue for immense career growth & innovation.

In this article, let’s take a deep dive & see how the digital powerhouses can pivot your front-end career 360 degrees & help you achieve your goals. 

What is a Progressive Web Application?

For starters, PWA bridges the gap between website and mobile experiences. 

They’re built using the same old traditional web technologies: HTML, CSS, and Java. They take advantage of the web ecosystem, inclusive of plugins, community, and the ease of deploying a website. They act like a normal website, you see on search engines. But this is where the term “progressive” comes into play. 

PWAs have the feel and functionality of a native app. They integrate modern APIs that offer reliability and the ability to install on every device. Therefore, you can access them on any device, on any browser.

Sounds Interesting? Doesn’t it? 

But you are still a step away from the real magic. The real marvel lies within its ability to transcend the traditional browser tab. 

All hail to the unsung heroes, “service workers”, because PWAs can: 

• Work offline: Got no WI-FI? No issue!
• Loads Quickly: Say bye-bye to long loading times. 
• Installable: Add PWAs on your home screen directly from your browser, in an app-like window, away from the browser clutter drama.
• Push notifications: Get timely alerts with push notifications. 

Alas, this proves that sometimes the most revolutionary changes are simply about doing what’s already good, even better. 

Characteristics of PWAs

Imagine being a highly skilled diplomat, always negotiating, trying to find the common ground, and ensuring seamless communication between two robust entities.

What if we tell you that this is the role progressive web applications typically plays between a web and a mobile application? 

Progressive web app development connects the best of both worlds without leaving anyone behind. The following features set them apart from their native counterparts:

1. Ultimate App-like Experience

It’s high time you strengthen your technical skillset in developing capabilities like offline access, push notifications, and home-screen installations. These PWA features are the crowd-pleasers, consistently driving engagement and retention. 

Now, just imagine your manager taking notice because your work directly contributed to a boost in quarterly profits. 

2. Platform Compatibility

As users are everywhere, brands want to reimagine the concept of responsiveness. They are looking for a skillset to deliver an app-like experience effortlessly. 

That being said, PWAs automatically adapt to various screen sizes, providing a consistent experience across desktops, laptops, tablets, or smartphones.

3. Improved Performance

One thing you must know about PWAs is that they are known for their speed & reliability. It loads faster than your normal websites, all thanks to the caching and optimized code.

4. Cost-Effectiveness

Companies are doubling down on PWAs because they offer returns at a lower development and maintenance cost compared to native apps. And that’s in your favor. 

When a technology boosts revenue, businesses invest more. That surge creates more job opportunities for those with the right skills. 

5. Connectivity Independence

Unlike native apps, PWAs use service workers, the background scripts that quietly do the heavy lifting to keep things running smoothly. They cache data and resources so your app can still work even when the internet isn’t playing nice. 

This means users can access content and perform an action without interruption, making the experience far more reliable.

6. Search Engine Optimization (SEO)

PWAs offer a strategic advantage in discoverability through SEO. Unlike native apps that depend on visibility within app stores, PWAs are indexed by search engines and can surface directly in organic search results. 

This not only broadens access for users actively searching for related products/services but also drives sustained, cost-effective user acquisition. By closing the gap between web and mobile, brands are now able to expand their digital reach without the constraints of app store algorithms.
