Build a Progressive Web App (PWA) for Online Notes

PWAs offer native app-like experiences with web technologies. Building this project teaches you offline support, service workers, Web App Manifests, push notifications, and syncing local storage or cloud data — highly relevant for modern full-stack developers.

Users can create, edit, delete, and search notes. The app works offline, offers install prompts, syncs across devices if logged in, and sends optional push notifications for reminders — blending web and mobile seamlessly.

Users access the app through their browser or install it on their device. All notes are saved locally for offline usage. If logged in, notes are synced across devices securely. Push notifications remind users of important notes or deadlines.

• Service workers cache app shell and static assets to allow offline usage even without an internet connection.
• Notes are stored locally in IndexedDB or localStorage when offline and synced to the cloud when online.
• Manifest and service worker configuration allows 'Add to Home Screen' install prompts on mobile and desktop.
• Optional push notifications keep users updated about important notes and tasks.
• Secure login options allow syncing notes across multiple devices (if user chooses to register/login).
