A real-time map of the NYC Subway System.
The backend API is written in Go and provides a single endpoint.
Returns a GeoJSON object with the best estimate of the position of every active train in the subway system.
Run docker-compose up to launch the backend and the client in development mode. The client will run on port 3000, and the backend is accessible on port 8080.
To launch a minified, static production client instead of the default development client, use docker-compose -f docker-compose-prod.yaml up.
For deployment on a public website, the client will need to be modified to request the train position GeoJSON from whatever URL is being used to proxy the backend Docker container.
