What prevents all apps from being PWAs?

Why Aren’t All Apps Progressively Web Apps (PWAs)?

While browsing through web.dev about Progressive Web Apps (PWAs), I came across some compelling insights. It seems like adopting PWAs could be considered a straightforward and strategic move.

The process appears uncomplicated: without the need to leverage any specific features instantly, you mainly need to integrate a manifest.json file, and your web app can transform into an installable application.

This brings me to a fundamental question: Why haven’t all modern applications transitioned to PWAs by default? Is there hidden complexity or obstacles that aren’t widely discussed? It seems like any web app could be converted in an hour, but what could possibly be the “catch”?

  1. Progressive Web Apps (PWAs) indeed offer a compelling approach to delivering app-like experiences via the web. They combine the features offered by most modern browsers with the benefits of mobile experiences. However, there are several reasons why not all apps are PWAs, and this includes technical, business, and strategic considerations. Let’s explore these in detail:

    1. Feature Limitations

    • Access to Device Features: Native apps traditionally have more access to device hardware and features (such as Bluetooth, NFC, advanced camera controls) compared to PWAs. Although this gap is closing, it still exists for certain APIs, which can limit the functionality of a PWA if comparable native-level access is required.

    2. Performance Considerations

    • Hardware Performance: Native apps often outperform PWAs in terms of processing speed and responsiveness due to their direct interaction with the device hardware and operating system.
    • Heavy Computations or Graphics: Apps requiring heavy computations or graphics processing might still favor native solutions for optimized performance.

    3. Business Strategy and Ecosystem Lock-in

    • App Store Presence: Businesses often prioritize having a presence in app stores (Google Play, Apple App Store) due to their vast user bases, discoverability, and monetization mechanisms.
    • User Expectations: Many users are accustomed to downloading apps from these app stores, and a PWA doesn’t provide this traditional app store experience.

    4. Browser Compatibility

    • Support Across Platforms: While browser support for PWAs has improved, discrepancies still exist, especially on platforms like iOS, where certain PWA features are more restricted compared to others.
    • Regression Risks: Ensuring consistent behavior across all browsers can be challenging and may require additional development effort.

    5. Integration Complexities

    • Existing Infrastructure: Large-scale or legacy applications might have intricate dependencies and complex architecture hindering quick transition to PWA.
    • Cost and Time: The perception that transitioning to a PWA can happen in an hour might underestimate the potential need for Restructuring.cloud/restructuring/” target=”_blank” rel=”noopener noreferrer”>restructuring or re-engineering certain parts of the app.

    6. Network Reliability and Offline Functionality

    • Caching Strategies: Although PWAs have offline capabilities, implementing efficient caching strategies to provide seamless experiences is non-trivial and can demand significant development overhead.

  2. This is a great question and a topic that deserves deeper exploration! While the technical aspects of converting a web app to a PWA might seem straightforward, there are several nuanced factors that can deter developers from making this transition.

    First, performance and offline capabilities are often reliant on how well the app is architected. For existing applications, especially those that didn’t originally plan for offline functionality or service workers, retrofitting these features can be complex. It often involves significant code refactoring and testing.

    Second, there are still concerns about compatibility and standardization across different browsers and devices. Although major modern browsers support PWAs, the experience can vary significantly—exposing developers to additional work to ensure consistent performance across platforms.

    Third, the user experience plays a crucial role. PWAs have great potential, but converting to a PWA means rethinking user interactions and workflows. Not all applications fit the PWA model seamlessly, especially those that rely heavily on complex interactions or require robust features like push notifications that may not yet be uniform across all platforms.

    Lastly, there are business considerations. Some organizations may hesitate to adopt PWAs due to existing investments in native mobile applications or specific business models that favor traditional app stores.

    In summary, while PWAs offer numerous advantages, the transition isn’t as simple as adding a `manifest.json` file. It involves comprehensive planning and consideration of technical, user experience, and business implications. It’s an exciting area of development, and I look forward to seeing more companies embrace PWAs as they
