Progressive Web Applications (PWA Development) combine the best features of web and mobile apps, offering users fast, reliable, and engaging experiences directly through a web browser. Introduced by Google in 2015, PWAs have gained popularity for providing app-like experiences—without needing to visit an app store. Looking for scalable custom software? At AssortTech, our core expertise lies in E-Commerce & Retail Innovations — where we transform your vision into powerful digital products.
What is a PWA?
A Progressive Web Application (PWA) is a type of web app designed to behave like a native mobile app. It works seamlessly across different platforms and devices and can be installed directly from the browser. PWAs include features like:
- Offline access
- Push notifications
- Hardware integration (camera, GPS, etc.)
- Faster performance via caching
These apps can also load content even in low-connectivity scenarios, evolving from Accelerated Mobile Pages (AMP) to enhance speed and reliability.
Three Pillars of PWA Development
- Capable
PWAs utilize modern web APIs—like WebRTC, WebGL, WebVR, and WebAssembly—to deliver feature-rich experiences. They also support upcoming APIs (e.g., file system access, clipboard integration) designed with user-first security. - Reliable
PWAs offer consistent performance regardless of network conditions. Users can interact with cached content offline, with quick load times and smooth navigation. - Installable
PWAs can be installed directly from the browser, appearing on home screens like native apps. Once installed, they operate independently of the browser, offering improved user interaction.
Core Elements of PWA Development
- Progressive Enhancement: Functions on all devices and browsers.
- Responsiveness: Adapts to various screen sizes.
- App-like Interface: Full-screen, smooth animations, home screen shortcuts.
- Offline Functionality: Uses cached data for offline access.
- Push Notifications: Keeps users engaged.
- Cross-platform Compatibility: Built using HTML, CSS, and JS.
- Seamless Updates: Automatically updated upon browser access.
- Service Workers: Manage cache and data for smooth offline experiences.
- HTTPS Protocol: Ensures data security through encryption.
Requirements for PWA Development
To build a successful PWA, developers must ensure:
- Browser Support: Major browsers like Chrome, Edge, and Firefox support most PWA features.
- Secure HTTPS Connection: Mandatory for service workers and push notifications.
