How to Create a Shopping Experience Like Amazon and Best Buy Without Installing Native Mobile Apps? Rise of PWAs.


In the fast-paced world of e-commerce, providing a seamless shopping experience to your customers is paramount. Companies like Amazon and Best Buy have set the gold standard for online retail, and while they have native mobile apps, it’s possible to create a similarly seamless experience without requiring users to install apps. If you’re wondering how that is possible, then you are in the right place. And if you said Progressive Web Apps, then you are on point and this blog is for you.

Progressive Web Apps: The New App Success Formula

Progressive Web Apps (PWAs) are a groundbreaking approach in the world of mobile and web application development. They have revolutionized the way businesses engage with their customers by providing a seamless and efficient shopping experience. These digital wonders are not only shaping the future of e-commerce but also transforming the way users interact with online services. Let’s delve deeper into why PWAs have become the go-to strategy for businesses, the distinct advantages they offer over native apps, and their remarkable growth in popularity. PWAs are changing the game for businesses that rely on web-based platforms for their online presence. Here’s why they’ve become a dominant force:


  • Accessibility for All: PWAs break down the barriers of device and operating system limitations. Unlike native apps, which require separate development for iOS and Android, PWAs work seamlessly across all platforms, from smartphones and tablets to desktops. This universal accessibility empowers businesses to reach a wider audience without fragmenting their development efforts.


  • No Installation Hassles: The biggest turn-off for many potential users when it comes to native apps is the requirement to download and install them. PWAs eliminate this friction by offering a one-click access via a web URL. Users can dive right into the application without the need for a time-consuming installation process or concerns about device storage space.


  • Offline Reliability: PWAs are designed to function even in challenging network conditions. This means users can continue browsing, selecting products, and even completing transactions when they’re offline or in areas with limited connectivity. This offline capability is a game-changer, especially in regions with unreliable internet access.
  • Speed and Responsiveness: PWAs are optimized for performance. They load quickly, offer a smooth and responsive user experience, and reduce bounce rates. Techniques like service workers and caching ensure that content loads swiftly, leading to higher user satisfaction and retention.


  • Cost-Effective Development: Developing and maintaining native apps for multiple platforms can be resource-intensive. PWAs, on the other hand, are based on web technologies like HTML, CSS, and JavaScript. This not only reduces development costs but also simplifies the development process, allowing businesses to allocate resources more efficiently.


  • Cross-Platform Consistency: PWAs offer a consistent user experience across different devices and operating systems. Businesses don’t need to worry about the nuances of each platform, ensuring a consistent brand image and functionality. This simplifies development, support, and maintenance.


  • Automatic Updates: PWAs can be updated by developers without user intervention. This means that users always have access to the latest version of the app, including bug fixes and new features, without having to manually update the app.

Why are PWAs popular?

The growing popularity of PWAs is driven by their ability to combine the best features of websites and native apps. The user-centric design, cost-effectiveness, cross-platform compatibility, and various other advantages are making PWAs the preferred choice for businesses seeking to provide a seamless, accessible, and high-performing shopping experience to their customers. As the digital landscape continues to evolve, the appeal of PWAs is likely to increase, making them a crucial component of the modern online ecosystem. The adoption of PWAs is a trend that’s rapidly gaining momentum. Several factors contribute to their increasing popularity:

  • Major Industry Players: Many renowned companies have successfully integrated PWAs into their e-commerce strategies. The likes of Twitter, Pinterest, Alibaba, and Flipkart have reported remarkable improvements in engagement, conversion rates, and user retention after implementing PWAs.
  • SEO Benefits: PWAs are search engine-friendly, as they are easily indexable. This can lead to better visibility, increased organic traffic, and ultimately higher conversions for businesses.
  • Personalized User Experience: PWAs allow businesses to harness user data and behavior, enabling the delivery of personalized experiences. This, in turn, enhances user retention and drives sales.


  • Reduced Bounce Rates: The speed, accessibility, and reliability of PWAs contribute to lower bounce rates and increased user engagement. These factors directly impact sales and revenue, making them an attractive choice for businesses.

How to Test PWAs efficiently?

Testing PWAs is essential to guarantee a seamless user experience, maintain the reliability of the app, and ensure compatibility with various devices and browsers. PWA testing helps identify and address issues related to cross-browser compatibility, offline functionality, performance, and more. It also helps in optimizing user experience and addressing potential security vulnerabilities. Testing Progressive Web Apps (PWAs) involves a series of critical steps and considerations to ensure that the application functions reliably and offers a seamless user experience. Let’s delve further into these key points for testing PWAs:

  1. Validate PWA Manifest: The PWA manifest file is a fundamental component that defines how the PWA behaves when installed on a user’s device. Testers should ensure that:
  • The manifest has a “name” or “short_name” property for the app’s name.
  • It has a “start_url” property to define the entry point of the PWA.
  • The “icons” property includes at least 192px and 512px-sized icons for various display contexts.

The “display” property is set to “standalone,” “fullscreen,” or “minimal-ui” to determine the app’s display mode.

  1. Validate Service Worker: Service workers are essential for PWA functionality, as they enable background processes and caching. Testers should confirm that a service worker is registered and correctly handles fetch events.

  2. HTTPS Security: PWAs should be served exclusively via HTTPS to ensure data security and user trust. Testers can use tools like Lighthouse to verify that the PWA is served securely.


  1. Responsiveness: Ensure that the PWA offers a responsive design that adapts to various screen sizes and orientations. Test on different devices to confirm that the user experience remains consistent.

  2. Offline Loading: A crucial aspect of PWAs is their ability to work offline. Testers should validate that at least critical pages of the PWA function offline and return HTTP 200 responses. Tools like Lighthouse or WireMock can be used for this purpose.

Metadata for ‘Add to Homescreen’: PWAs should provide metadata that prompts users to “Add to Homescreen.” Testers can use tools like Lighthouse to check if this metadata is correctly configured.

  1. Page Rendering and Transitions: Smooth transitions and page rendering are essential for a positive user experience. Test the PWA’s performance, especially on slower networks, to ensure that pages render promptly without any delays or snappiness.
  2. URL Structure: Each page within the PWA should have a unique URL, and these URLs should be easily shareable and directly accessible in new browser tabs.
  3. Push Notifications: Test push notifications to ensure that they are not overly aggressive. Verify that notifications are respectful of user preferences and that they ask for permission as required by the user’s browser.
  4. Functionality Testing: Functional testing is a critical step to validate that the PWA behaves according to the defined requirements. It covers all aspects of the application’s functionality and can be conducted manually and through automation.


The growing popularity of PWAs is driven by their ability to combine the best features of websites and native apps. The user-centric design, cost-effectiveness, cross-platform compatibility, and various other advantages are making PWAs the preferred choice for businesses seeking to provide a seamless, accessible, and high-performing shopping experience to their customers. However, testing PWAs calls for a different approach to ensure delivery of a reliable, fast, and accessible experience to users. By systematically addressing various considerations while testing a PWA, you can ensure that the application is not only reliable and secure but also offers an outstanding user experience.
