JarCastingredis4cats
Redis client built on top of Cats Effect, Fs2 and the async Java client Lettuce.
Quick Start
import cats.effect._
import cats.implicits._
import dev.profunktor.redis4cats.Redis
import dev.profunktor.redis4cats.effect.Log.Stdout._
object QuickStart extends IOApp {
override def run(args: List[String]): IO[ExitCode] =
Redis[IO].utf8("redis://localhost").use { cmd =>
for {
_ <- cmd.set("foo", "123")
x <- cmd.get("foo")
_ <- cmd.setNx("foo", "should not happen")
y <- cmd.get("foo")
_ <- IO(println(x === y)) // true
} yield ExitCode.Success
}
}
The API is quite stable and heavily used in production. However, binary compatibility won't be guaranteed until we reach 1.0.0.

Dependencies
Add this to your build.sbt for the Effects API (depends on cats-effect):
libraryDependencies += "dev.profunktor" %% "redis4cats-effects" % Version
Add this for the Streams API (depends on fs2 and cats-effect):
libraryDependencies += "dev.profunktor" %% "redis4cats-streams" % Version
Log4cats support
redis4cats needs a logger for internal use and provides instances for log4cats. It is the recommended logging library:
libraryDependencies += "dev.profunktor" %% "redis4cats-log4cats" % Version
Running the tests locally
Start both a single Redis node and a cluster using docker-compose:
> docker-compose up
> sbt +test
