In: Web Development

As the market of web development continues to evolve at an unprecedented pace, one innovation that’s been garnering significant attention among developers and businesses alike is Progressive Web Apps (PWAs). Initially introduced by Google in 2015, these modern web applications are engineered to bring a seamless, app-like browsing experience, combining the best of both web and native applications. Particularly in Malaysia, with a mobile penetration of 140% in 2023, the potential for PWAs is immense. Recent years have seen a surge in PWA adoption, indicating their significant role in the future of web development. Giants like Google, Microsoft, and Apple are not just advocating for PWAs but actively integrating them into their business models. This blog dives deep into PWAs – understanding their rise, benefits, limitations, and potential impact on the future of web development.

What Are Progressive Web Apps?

Progressive Web Apps, commonly known as PWAs, are a form of web applications that utilize modern web capabilities to deliver user experiences similar to those provided by native apps. They conform to specific criteria, reside on servers, and are accessible via unique URLs. Notably, they can be indexed by search engines, ensuring their discoverability and blending the advantageous attributes of both conventional websites and native mobile apps.

Key Features of PWAs

While traditional web apps can be less resource-intensive and typically have a broader reach, they often lack the advanced functionalities found in native apps. In contrast, native apps, while offering robust user experiences and full access to device capabilities, are usually costlier and time-consuming to develop and maintain. PWAs emerge as a middle ground, providing an optimal blend of web’s wide reach and native’s rich functionality. These apps encompass a range of features that make them stand out in the crowded digital landscape. Here are some of their distinctive features:

Responsive: PWAs are designed to work on any device, offering a consistent user experience from desktop to mobile.

Connectivity-independent: These apps can work offline or on low-quality networks, ensuring uninterrupted access.

Fresh: PWAs are always up-to-date due to the service worker update process. This means users will always have access to the latest version of the app.

Safe: As they are served via HTTPS, PWAs prevent data tampering to a great extent and effectively protect user information.

Discoverable: Thanks to service worker registration scope, search engines can hassle-freely find PWAs, making them highly discoverable.

Re-engageable: Through features like push notifications, PWAs can re-engage users with customisable updates and offers.

Linkable and Shareable: PWAs can be easily shared via a URL without requiring complex installation.

The Perks of Progressive Web Apps

PWAs bring several distinctive advantages to the table, for both businesses and end users, helping them navigate the many challenges of the digitally-driven paradigm. Here are some of the most notable benefits of PWAs:

Enhanced User Experience

PWAs take user experience to the next level, combining the best features of web and native apps. They are fast, engaging, and reliable, offering a full-screen experience without the browser’s address bar. Furthermore, they’re designed to be mobile-first, ensuring optimal performance and an intuitive interface on the devices users depend on most.

Cost and Time-Effective Development

Building a PWA can be more time and cost-effective than developing separate apps for different platforms. How? They are created using a single codebase that works across platforms and devices, which reduces development and maintenance costs. In addition to that, they bypass app stores, eliminating the need for approval processes and update delays.

Improved Performance

PWAs load quickly and offer smooth scrolling and navigation, even in uncertain network conditions. This is largely thanks to service workers, a type of web worker that can cache app resources. By storing core files and resources locally, PWAs can drastically improve load times and overall performance, leading to increased user engagement and higher conversion rates.

Offline Capabilities

One of the most significant advantages of PWAs is their ability to function offline or on low-quality networks. By pre-caching key resources, PWAs can ensure core app functionality even without an internet connection. This not only improves user experience but also increases accessibility for users with unstable or limited network access.

SEO Advantages

PWAs are discoverable in search engines and thus, can significantly boost a business’s online visibility. Moreover, factors like mobile-first design, fast load times, and engaging UX can positively impact search engine rankings, driving more organic traffic to the app.

Real-world Use Cases of PWAs

Progressive Web Apps are not just theoretical constructs; they have been implemented by some of the top brands across various sectors, yielding impressive results. Let’s explore a few of these success stories:

PWA use case in retail (AliExpress)

AliExpress, a popular e-commerce platform, turned to PWA technology to enhance its mobile web experience. Post PWA implementation, the company reported a whopping 104% increase in conversion rates for new users across all browsers. Also, they saw a 2X increase in pages visited per session and an astounding 74% increase in time spent per session.

PWA use case in social media (Twitter Lite)

Twitter introduced its PWA named ‘Twitter Lite’ in 2017, aiming to deliver a faster, more reliable, and more engaging user experience. Twitter Lite led to a 65% increase in pages per session and a 20% decrease in bounce rate. Moreover, it was just 3% of the size of Twitter’s native Android app, reducing data usage.

PWA use case in news and publishing (Forbes)

Forbes adopted a PWA approach for its new mobile experience, hoping to increase user engagement and session duration. And the outcome was remarkable: the PWA’s visual narrative storytelling led to a 100% increase in session duration. It is estimated that this new strategy will get the popular new platform 38 million monthly mobile readers.

D. PWA use case in travel and hospitality (Trivago)

Trivago, the popular travel company, saw an opportunity to improve its user experience and reach more users by creating a PWA in 2017. As a result, Trivago witnessed a 97% increase in clickouts to hotel offers, while users added its PWA to the home screen an impressive 150% more often.

Challenges and Limitations of PWAs

Like any technology, Progressive Web Apps are not without their challenges and limitations. Even though they have been celebrated for bridging the gap between traditional web applications and native mobile apps, there are certain areas where they fall short.

One of the significant limitations of PWAs is the inconsistent support across different browsers. While Google Chrome and Mozilla Firefox offer extensive PWA support, Safari lags behind, particularly regarding features like push notifications and offline storage. This inconsistency can cause disparities in user experience and performance across different browsers.

Additionally, PWAs may not fully tap into all device capabilities. For instance, advanced camera controls, biometric authentication, geofencing, Bluetooth connectivity, and other advanced sensors are often inaccessible or limited in scope.

However, these challenges do not dim the shining future of PWAs. Many of these limitations are likely to be addressed as the technology matures and adoption grows. The core benefits of PWAs position them strongly in the evolution of web technologies in Malaysia and worldwide. With that in mind, let’s take a deeper look into the promising future of Progressive Web Apps.
