  1. Start your service automatically

This is up to you :-) However, here's a suggested procedure:

  • create a start script in home; NODE_ENV allow you to create a personalized configuration yaml. Check out 'npm config.js'
echo "cd /home/pi/robocar-devices && export NODE_ENV=alpha && npm start" > start_service.sh
chmod +x start_service.sh
  • run the script at startup
sudo crontab -e

Add a line :

@reboot sh /home/pi/start_service.sh >/home/pi/logs/cronlog 2>&1 &
