- Offline Functionality: Through service workers, PWAs can work offline or with poor network conditions by caching resources.
- App-Like Experience: PWAs provide an app-like user experience with a similar look and feel to native apps.
- Push Notifications: They support push notifications, enabling real-time updates and engagement.
- Secure: PWAs are served over HTTPS to ensure content is secure and tamper-proof.
- Installable: Users can add PWAs to their home screen without going through an app store, making them easily accessible.
- Linkable: PWAs can be easily shared via URL without complex installation processes.
Benefits:
- Cost-Effective Development: Developing a single PWA can be more cost-effective than creating separate native apps for different platforms.
- Improved Performance: By caching resources and optimizing performance, PWAs can provide faster loading times and better overall performance.
- Increased Engagement: Features like push notifications and home screen access can drive user engagement.
