Turns on/off lights (or anything else) connected to a Raspberry Pi's GPIO pins through a reactive socket-based web connection.
cd /path/to/lights/
yarn # install npm dependencies (frontend and backend)
Derived from create-react-app, the frontend behaves like any other CRA project;
yarn start # run local development server e.g. http://localhost:3000/
yarn build # ... or compile a build for production hosting
You'll want to yarn build and then go host the resulting build/ dir somewhere when you're reading to go to production. It does not have to be hosted on the same server as the backend.
Backend is just Node's http server wrapped in Express. The entire contents of the backend are in server.js while configuration variables are kept as env vars (Check .env file).
Start the backend server with:
yarn server
By default, the config stored in the .env file will be used. Adjust them to your liking (You'll need to restart your server process for changes to take effect):
export REACT_APP_DEBUG='true'
export REACT_APP_LIGHTS_PIN_LIST='[11, 15, 16]' # Pin position number
NOTE: These variables are also used in the frontend.
