Web App and Progressive Web App (PWA) are two terms often used in the context of web development. While they share similarities, there are key differences between them. Let's understand these differences:
- Web App: A web app is a software application that is accessed through a web browser over the internet. It requires an active internet connection to function.
- Progressive Web App: A Progressive Web App (PWA) is a type of web app that incorporates modern web technologies to provide a more app-like experience. PWAs are designed to work offline and offer features such as push notifications and device hardware access.
- Web App: A web app does not require installation. Users can simply access it by entering the app's URL in a web browser.
- Progressive Web App: PWAs can be installed on the user's device, similar to native mobile apps. They can be added to the device's home screen and launched like any other app, providing a more seamless experience.
3. Offline Functionality:
- Web App: Web apps typically require an internet connection to function properly. If the user loses internet connectivity, the app's functionality may be limited or inaccessible.
- Progressive Web App: PWAs are designed to work offline or with limited connectivity. They can cache and store necessary resources, allowing users to access the app and content even when offline. When the connection is restored, the PWA can synchronize data with the server.
- Web App: Web apps provide a consistent user experience across different platforms and devices. They adapt to the device's screen size and capabilities but may lack some native app-like interactions.
- Progressive Web App: PWAs aim to provide a more immersive and app-like experience. They can utilize features like push notifications, full-screen mode, and device hardware access (such as camera or geolocation), bridging the gap between web and native apps.
5. App Store Distribution:
- Web App: Web apps are not distributed through app stores. They are accessible directly through a web browser, eliminating the need for app store approval or compliance.
- Progressive Web App: PWAs can be distributed through app stores like Google Play Store or Microsoft Store. This allows users to discover and install PWAs from familiar app store platforms.
6. Development and Maintenance:
- Web App: Web apps are typically built using web technologies like HTML, CSS, and JavaScript. They can be developed and maintained using standard web development tools and frameworks.
- Progressive Web App: PWAs require additional considerations during development to incorporate PWA features like service workers and manifest files. These features enable offline functionality, installation capabilities, and other PWA-specific features.
