Like doobie, but for Redis.
Brick is an open-source library which provides a set of tools to integrate Redis into the cats and cats-effects world.
It currently provides an implementation for the lettuce library
import cats.effect.IO
import com.datastax.driver.core.Session
import eu.monniot.brick
import eu.monniot.brick.lettuce.Transactor
import eu.monniot.brick.commands._ // TODO Fix this import
// Create the redis session (or reuse a lettuce RedisClient)
implicit val transact = Transactor.fromRedisClient("redis://password@localhost:6379/0")
val getAndExpire: CommandIO[String] = for {
v <- get("myKey")
_ <- expire("myKey")
} yield v
// Returns an effect monad which will execute our redis commands
val result: IO[String] = getAndExpire.exec
val transaction: CommandIO[String] = for {
v <- hget("myKey", "myField")
v2 = s"hello $v" // do some useful work :)
_ <- hset("myKey", "myField", v2)
} yield v2
// Returns an effect monad with our transactions commands executed in a MULTI/EXEC block
val result: IO[String] = transaction.multiBrick is published to maven Central and cross built against scala 2.12.4 and 2.11.12, so you can just add the following to your build:
libraryDependencies += "eu.monniot.brick" %% "brick-core" % "0.1.0"
libraryDependencies += "eu.monniot.brick" %% "brick-lettuce" % "0.1.0"The Brick documentation is available at https://francois.monniot.eu/brick.
