[Layyzyy]

Description

This PR fixes issue #16 by implementing functionality to display user details (username, email, and number of attacks run) on the UI when the user is logged in.

Changes Made

Backend (auth-server)

1. handlers.go: Added getUserInfoHandler function that:

   • Fetches user details from the database using the authenticated user ID
   • Counts the number of reports/attacks for the user
   • Returns user information including username, email, attacks count, and other relevant details

2. main.go: Added new route /api/auth/getUserInfo with authentication middleware

Frontend

3. Navbar.jsx:
   • Added useEffect to fetch user data when component mounts
   • Updated API call to use the new /api/auth/getUserInfo endpoint
   • Display fetched user details (username, email, attacks count) in the profile card
   • Replaced hardcoded placeholder values with actual user data

Testing

• Tested user login flow
• Verified user details are fetched and displayed correctly
• Confirmed attacks count is accurately reflected

Fixes

Closes #16
