Log Examples

backend.log

[13:30:15.00] ========================================
[13:30:15.00] Starting backend service...
INFO:     Started server process [12345]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:3000

frontend.log

[13:30:20.00] Starting frontend service...
VITE v5.0.0  ready in 1234 ms

➜  Local:   http://localhost:8080/
➜  Network: use --host to expose

Notes

1. First-time frontend startup: If dependencies are not installed, the script will automatically run npm install
2. Virtual environment: Ensure backend uses Python virtual environment (venv)
3. Firewall: Ensure firewall allows ports 3000 and 8080
4. Antivirus: Some antivirus software may block scripts, need to add to whitelist

Troubleshooting

Backend Won't Start

1. Check if Python virtual environment is correctly installed
2. View backend.log log file
3. Confirm port 3000 is not in use
4. Check if dependency packages are complete: venv\Scripts\pip list

Frontend Won't Start

1. Check if Node.js is installed: node --version
2. View frontend.log log file
3. Confirm port 8080 is not in use
4. Manually install dependencies: Enter frontend directory and run npm install

Process Won't Stop

1. Manually find process: tasklist | findstr python
2. Force stop: taskkill /F /IM python.exe
3. Check port: netstat -ano | findstr :3000

Advanced Usage

Modify Ports

• Backend: Modify port number in api_server.py
• Frontend: Modify port number in vite.config.js
• After modification, need to sync update port checking logic in scripts

Custom Log Location

• Modify LOG_FILE variable in scripts
• Ensure directory exists and has write permissions

Technical Support

If you encounter issues, please check:

1. Log files (backend.log, frontend.log)
2. PID files (backend.pid, frontend.pid)
3. Port usage (netstat -ano)
4. Process list (tasklist)
