git clone [email protected]:satoshipay/stellar-candy-dispenser.git
npm install
Use with node 8, please. The rpi-ws281x-v2 package that controls the LEDs doesn't build on latest node versions.
In our case we just launched an SSH server on the Raspberry and added our ~/.ssh/id_rsa.pub to the Raspberry user's ~/.ssh/authorized_keys.
Deployment is then just a simple scp command to copy the files. Not super elegant, but straight forward.
scp -r *.js package* src/ [email protected]:/path/to/deployment/
Run the program in watch mode and on testnet:
sudo npm run dev
Run the program in production and on mainnet:
sudo npm start
Create a .env file in the project directory.

In order to make the application start automatically on every boot, we registered a new service called stellar-candy-dispenser.
- Create a new file for the service in the
/etc/init.d/directory and open it (sudo nano /etc/init.d/stellar-candy-dispenser). - Use this and replace the
dirandPATHto fit the needs of your local installation. - To register your new service call
sudo update-rc.d stellar-candy-dispenser defaults. - Afterwards you can control the service with
sudo service stellar-candy-dispenser start/stop/restart/status.
Try npm install --unsafe-perm.
If you run into errors like Can't lock /var/run/pigpio.pid and Error: pigpio error -1 in gpioInitialise; while trying to start the application, make sure that the application is not currently running in background because of the service (as only one instance can run at a time because of the access to pigpio).
Stop the service with sudo service stellar-candy-dispenser stop and check in the service status (sudo service stellar-candy-dispenser status) that no other processes are listed in CGroup. If processes are still running after you stopped the service you can kill them manually with kill 'pid'.
