Installation

Add dependencies to build.sbt.

val libraryName = "dynamodb"
val version = "1.2.0"

libraryDependencies += Seq(
  "com.github.j5ik2o" %% s"reactive-aws-$libraryName-core" % version,
  "com.github.j5ik2o" %% s"reactive-aws-$libraryName-monix" % version, // optional
  "com.github.j5ik2o" %% s"reactive-aws-$libraryName-akka" % version, // optional
  "com.github.j5ik2o" %% s"reactive-aws-$libraryName-cats" % version, // optional
)

Usage

The following is an example of dynamodb. The usage is almost the same as other libraries.

import com.github.j5ik2o.reactive.aws.dynamodb._
import com.github.j5ik2o.reactive.aws.dynamodb.implicits._ // import for enrich
import software.amazon.awssdk.services.dynamodb.model._
import software.amazon.awssdk.services.dynamodb.{ DynamoDbAsyncClient => JavaDynamoDbAsyncClient }

val underlying = JavaDynamoDbAsyncClient
  .builder()
  // ...
  .build()
val client = DynamoDbAsyncClient(underlying) // Pass the Java client instance to the constructor
val putItemRequest = PutItemRequest // Java types can be used as is
  .builder()
  .tableName(tableName)
  .itemAsScala(
    Map[String, AttributeValue](
      "Id"   -> AttributeValue.builder().s("abc").build(),
      "Name" -> AttributeValue.builder().s("xyz").build()
    )
  ) // use the enriched Scala method
  .build()
val putItemResponseFuture = client.putItem(putItemRequest)

How to build

Run the following commands (Maven is required to run mvnInstall or mvnClean)

$ git submodule update --init
$ sbt mvnClean mvnInstall // first time only
$ sbt compile
