Service Name: DeepFocus Backend API

Description:

The DeepFocus Backend API is an Express.js-based service designed to handle user authentication, activity tracking, and email notifications. It provides endpoints for user sign-up and login, daily and weekly activity data persistence, and backend email functionality. The service is secured with JWT-based authentication and supports cross-origin requests (CORS) for integration with frontend applications. The API also includes health check and database connectivity endpoints for monitoring and diagnostics.

Key Features:

Authentication: JWT-based user authentication and authorization via /api/v1/auth. Activity Tracking: Enables tracking and persistence of daily and weekly user activity at /api/v1/activity. Email Notifications: Provides email-related functionalities at /api/v1/emails. Health Check: A simple endpoint (/api/v1/health) to monitor the server’s health. Database Connectivity: Verifies connection to the MongoDB database via /api/v1/test-db.
