A set of type definition and utility to implement AWS Lambda functions.
This is NOT a type definition for AWS Lambda API in aws-sdk-js. It can be found in aws-sdk-scalajs-facade.
exoego/scala-js-nodejs offers type definition and utilities for Node.js API.
| ScalaJS 0.6.28+ | ScalaJS 1.x | |

| Scala 2.12 | ✔️ (0.9.0 was final) | ✔️ (0.11.0 was final) |
| Scala 2.11 | N/A | N/A |
| Scala 2.10 | N/A | N/A |
- ✔️ Supported

}
private def handle(event: APIGatewayProxyEvent)(implicit ec: ExecutionContext): Future[APIGatewayProxyResult] = Future {
APIGatewayProxyResult(
statusCode = 200,
body = "hello " + event.body,
headers = js.defined(js.Dictionary("Content-Type" -> "text/plain"))
)
}
}Some of pre-defined handler traits:
- APIGatewayProxyHandlerV2
- AppSyncResolverHandler
- DynamoDBStreamHandler
- S3Handler
- SNSHandler
Each has Async~ variant that returns js.Promise instead of accepting callback.
