Funnel

Service which filters and sends out data to all listening clients over websockets. This service expects the data to be sent over grpc.

Configuration

Environment

• GRPC_PORT: mendatory under which the grpc server runs
• WEBSOCKET_PORT: mendatory under which port the websocket port runs
• API_DOMAIN: http domain of an running state-api

Filter

{
    "lines": [9, 11],
    "positions": [],
    "regions": [0],
    "enrich": true
}

This would only let telegrams from line 9 and 11 from region 0 (dresden). This Json just needs to be send to the websocket sending it again will overwrite the previous filter.
