import io.github.paoloboni.binance.{BinanceClient, BinanceConfig}
import cats.effect.{ExitCode, IO, IOApp}
import fs2._
import log.effect.fs2.SyncLogWriter._
import scala.concurrent.duration._
object PriceMonitor extends IOApp {
val config = BinanceConfig(
scheme = "https",
host = "api.binance.com",
port = 443,
infoUrl = "/api/v1/exchangeInfo",
apiKey = "***",
apiSecret = "***"
)
override def run(args: List[String]): IO[ExitCode] = {
implicit val log = consoleLog[IO]
BinanceClient[IO](config)
.use { client =>
Stream
.awakeEvery[IO](5.seconds)
.repeat
.evalMap(_ => client.getPrices())
.evalMap(prices => log.info("Current prices: " + prices))
.compile
.drain
}

{ t =>
log.error("Something went wrong", t)
ExitCode(1)
},
