Angular PWAs: Your Anchor in the Digital Ocean | Ankita Sood | ng-conf 2024
Learn how Progressive Web Apps modernize Angular applications with offline capabilities, cross-platform support, and native-like features - without separate codebases.
- Progressive Web Apps (PWAs) provide a middle ground between native apps and traditional websites, offering better performance and user engagement
-
Converting an Angular app to PWA is straightforward using
ng add PWA, which adds service worker and manifest files - PWAs can work offline through caching APIs, providing seamless experience even with spotty internet connections
- 38% of PWA sessions were recorded on desktop, showing PWAs aren’t just for mobile devices
- Users prefer not to download native apps for single tasks - 50% would rather use a website on their phone
- PWAs solve the software distribution problem by eliminating the need to maintain separate codebases for web, iOS, and Android
-
Key PWA features include:
- Installation capability
- Offline access
- Push notifications
- Responsive design across devices
- Background task processing
- PWAs reduce development overhead as only one codebase needs to be maintained versus multiple for native apps
-
Performance optimization in Angular PWAs can be achieved through:
- Defer loading components
- Conditional rendering based on device/screen size
- Service worker caching
- Major platforms like GitHub and YouTube are offering PWA versions of their applications
