Source for service that is backend for BAR Live Services https://bar-rts.com/. The frontend is in https://github.com/Jazcash/bar-live-services.
There are two services that share a lot of the code and operate on the same database, processor and rest API.
The processor is running in the background and doing more heavy computations. It covers processing of maps, replays and balance changes from git repository. The changes are pulled in periodically, for maps and replays they are pulled in by watching local filesystem directories, and for balance changes by looking them up using GitHub API.
Rest API is hosting all the endpoints used by the BAR Live services frontend. The endpoints primarily serve data that was filled in by the processor component to the database, but it also has components that communicate with the teiserver to pull dynamic information from there: leaderboards and live battle list.
You need to install nodejs version 14: that's the version that is used at the moment. The service depends on PostgreSQL and Redis, so you need to have them installed and running. One of the easier ways to do that is to use docker:
docker run --name bar-db-postgres -e POSTGRES_PASSWORD=postgres -d postgres
docker run --name bar-db-redis -d redis
Then to cleanup or start again you can use standard docker commands docker {stop|rm|start} bar-db-{redis|postgres}.
Then, it's best if you setup the config.json file. You can copy the example
file from config.json.example and edit it to your liking. See the file
src/bar-db-config.ts for full list of options. Out of the box you might for
sure need to update the IP address of the postgres and redis containers, you
can get them with:
$ docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' bar-db-{postgres,redis}
172.17.0.2
172.17.0.3
Notice that example config doesn't have credentials set for some of the components, so for development of those component you need to acquire them yourself.
You can start processor and rest API with respectively:
npm run build && npm run processor
and
npm run build && npm run rest-api
