Top Stations

This service for Element43 serves a list of top stations by market volume, based on data gathered from esi-markets. The statistics are updated hourly and persisted to disk using BoltDB.

Issues can be filed here. Pull requests can be made in this repo.

Interface

The service's gRPC description can be found here.

Installation

Either use the prebuilt Docker images and pass the appropriate env vars (see below), or:

• Install Go, clone this repo into your gopath
• Get and run esi-markets
• Set the ESI_MARKETS_HOST environment variable (see below)
• Run go get ./... to fetch the service's dependencies
• Run bash generateProto.sh to generate the necessary gRPC-related code
• Run go build to build the service
• Run ./top-stations to start the service

Now a gRPC server will listen on port 43000 unless configured otherwise, serving stats data once it has been generated.
