JarCastingslick-effect
Compatibility tools for Slick + cats-effect. Released for Scala 2.12 and 2.11.
Usage
Add the dependency. SBT:
"com.kubukoz" %% "slick-effect" % "0.3.0"
Ammonite:
$ivy.`com.kubukoz::slick-effect:0.3.0`
Coursier:
com.kubukoz::slick-effect:0.3.0
Instances
Import the instances:
import slickeffect.implicits._
//an implicit EC is needed for cpu-bound work on DBIOs (map, flatMap)
import scala.concurrent.ExecutionContext.Implicits.global
//the instances will be in implicit scope
scala> Async[slick.dbio.DBIO]
res0: Async[slick.dbio.package.DBIO] = slickeffect.DBIOAsync@434c179e
[EXPERIMENTAL] Transactor (from 0.3.0-M2 onwards)
You can use slick-effect to run your DBIOs. This functionality is experimental, and the API may change.
If you still want to use it, add a dependency on the transactor module:
"com.kubukoz" %% "slick-effect-transactor" % "0.3.0"
Create a transactor:
val transactorResource: Resource[IO, Transactor[IO]]
.fromDatabase[IO](IO(Database.forURL("jdbc:h2:mem:"))) //or .fromDatabaseConfig
.map(_.configure(config.transactionally)) //or any DBIO ~> DBIO
.use(_.transact(action))
val result: DBIO[Int] = ???
transactorResource.use { tx =>
tx.transact(result): IO[Int]
}
