s3dsl
Minimal, stream based S3 DSL. Depends on aws-java-sdk-s3.
Getting s3dsl
If you're using SBT, add the following line to your build file:
libraryDependencies += "com.github.wirthan" %% "s3dsl" % <version>
Quick Start
Initialize an interpreter
s3dsl provides a function that returns a cats-effect interpreter:
import s3dsl.S3Dsl._
import s3dsl.domain.S3._
val config = S3Config(
creds = new BasicAWSCredentials("BQKN8G6V2DQ83DH3AHPN", "GPD7MUZqy6XGtTz7h2QPyJbggGkQfigwDnaJNrgF"),
endpoint = new EndpointConfiguration("http://localhost:9000", "us-east-1"),
blockingEc = ExecutionContext.fromExecutor(Executors.newCachedThreadPool)
)
val cs = IO.contextShift(ExecutionContext.fromExecutor(Executors.newFixedThreadPool(3)))
val s3 = interpreter(config, cs)(IO.ioConcurrentEffect(cs))Use the interpreter
val path = Path(BucketName("mybucket"), Key("blob.txt"))
val blob = "abc".getBytes
]
val content: Stream[IO, Byte] = for {
_ <- Stream.emits(blob).covary[IO]
.through(s3.putObject(path, blob.length.longValue))
.compile.drain
content <- s3.getObject(path, 1024)
} yield content
