Manual Testing Steps

1. Start Game Session:

   # Run migration first
   npm run migrate
   
   # Start server
   npm start
   
   # Test session start
   curl -X POST http://localhost:5000/api/nexus/sessions/start \
     -H "X-Nexus-API-Key: test-key" \
     -H "X-Nexus-Player-ID: player-1" \
     -H "Content-Type: application/json" \
     -d '{"nexusPlayerId":"player-1","gameId":"test-game","gameName":"Test Game"}'
   

2. Test Friend System:

   # Send friend request
   curl -X POST http://localhost:5000/api/friends/request \
     -H "Authorization: Bearer <token>" \
     -H "Content-Type: application/json" \
     -d '{"targetIdentifier":"friend@nexus.aethex.cloud"}'
   
   # Get friends
   curl http://localhost:5000/api/friends \
     -H "Authorization: Bearer <token>"
   

3. Test Lobby System:

     -d '{"gameId":"test-game","maxPlayers":4}'
   

4. Test Overlay:

   • Open http://localhost:5173/overlay?session=test-session
