Troubleshooting Steps:

1. Check if the request hits the server → Add this to deleteUser:

   log.Println("DELETE request received for ID:", id)
   

   If nothing shows in logs, request isn't reaching the handler.

2. Verify the id is valid → Convert to integer before querying:

   idInt, err := strconv.Atoi(id)
   if err != nil {
       log.Println("Invalid ID:", id)
       w.WriteHeader(http.StatusBadRequest)
       return
   }
   

3. Check if the user exists → Run manually in Postgres:

   SELECT * FROM users WHERE id = 1;
   

   If no result, your DELETE won't work.

4. Confirm the row is deleted → After Exec, check:

   rowsAffected, _ := result.RowsAffected()
   if rowsAffected == 0 {
       log.Println("No user deleted")
       w.WriteHeader(http.StatusNotFound)
       return
   }
   

5. CORS Issue? → If using a browser, check DevTools (Network > XHR) and ensure DELETE isn't blocked.

Try these and check your logs. Let me know what you find! 🚀
