CI Status Gitter Chat Maven Central Cats friendly MergifyStatus Scala Steward badge

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.

If you like it, give it a ! If you think we could do better, please let us know!

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

ProfunKtor

A Profunctor is just a bifunctor that is contravariant in the first argument and covariant in the second. What's the problem?
