An idiomatic functional cats-effect compatible bindings to IEX Cloud API for Scala (2.13 yet).
import com.iexcloud4s.http._
import com.iexcloud4s.stocks.v1._
import cats.effect._
import scala.concurrent.ExecutionContext.Implicits.global
implicit val contextShift: ContextShift[IO] = IO.contextShift(ExecutionContext.global)
def makeClient(token: String): Resource[IO, IEXClient[IO]] =
ClientBuilder
.apply[IO](global)
.withToken(token)
.resource
def stockPreviousDayPriceChange(stock: String)(implicit client: IEXClient[IO]): IO[BigDecimal] =
previousDayPrice(
5F69
stock).map(_.change)
Some APIs also allow to retrieve separate data columns, iexcloud4s utilizes GADT to perform that in a typesafe manner.
def stockPERatio(stock: String)(implicit client: IEXClient[IO]): IO[BigDecimal] =
keyStatsField(stock, KeyStats.PERatio)
final case class PriceChangeAndPE(priceChange: BigDecimal, peRatio: BigDecimal)
def stockPriceChangeAndPE(token: String, stock: String): IO[PriceChangeAndPE] =
makeClient(token).use { implicit client =>
for {
priceChange <- stockPreviousDayPriceChange(stock)
peRatio <- stockPERatio(stock)
} yield PriceChangeAndPE(priceChange, peRatio)
}
