This task involves developing a notification system within our application to keep users informed about relevant activities and events. Notifications play a crucial role in enhancing user engagement and providing timely updates about interactions within the platform.

The implementation will include creating user interface components for displaying notifications, managing notification settings, and handling notification actions. Backend logic will be implemented to generate and send notifications based on various user activities and events.

Notifications may include alerts for actions such as receiving likes on repositories, receiving messages from friends, new friend requests, comments on repositories, and other relevant interactions. Users should have the ability to customize their notification preferences and manage their notification history.

The implementation of a notification system ensures that users stay informed about important activities and events within the application, fostering better engagement and interaction among users.
