Make your web app feel native: Unlocking the power of PWAs and push notifications

At our Friday Talk, Saša Mehmedagić, our software engineer, explored the transformative potential of Progressive Web Apps (PWAs) and their ability to bridge the gap between web and native applications.

Saša demonstrated how PWAs can deliver native-like experiences while maintaining the accessibility and cross-platform benefits of web technologies.

Key building blocks of a PWA

Saša held the audience’s attention by breaking down the essential ingredients needed for a successful PWA implementation, including the manifest file, service worker scripts, and the critical requirement for HTTPS security. He delved deep into the world of push notifications, comparing their capabilities against traditional in-app notifications and highlighting their power to engage users even when applications are closed or running in the background.

Cross-platform considerations

Furthermore, Saša methodically examined platform-specific support across different browsers and operating systems, paying particular attention to iOS limitations and the unique requirements for Safari-based implementations. He explained how VAPID (Voluntary Application Server Identification for Web Push) enables application servers to authenticate themselves with push services, eliminating dependency on third-party messaging platforms.

Practical implementation strategies

Throughout his presentation, Saša emphasized practical implementation strategies for managing push subscriptions, from initial setup and permission handling to dealing with expired subscriptions and re-authentication scenarios. He provided comprehensive guidance on subscription lifecycle management, ensuring developers understand how to maintain reliable push notification services across multiple devices and user sessions.

Making complex concepts accessible

In this session, Saša explored what Progressive Web Apps (PWAs) are and what it takes to turn a regular web app into an installable, app-like experience.

His approach combined theoretical knowledge with hands-on demonstration, making complex concepts accessible to developers looking to enhance their web applications with native-like capabilities.
