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.

How to use

Add dependency in build.sbt.

// For Node.js v12
libraryDependencies += "net.exoego" %%% "aws-lambda-scalajs-facade" % "0.10.0"

Import and code.

import scala.scalajs.js
import net.exoego.facade.aws_lambda._

object MyFirstLambda extends APIGatewayProxyHandler {
  @js.annotation.JSName("apply")
  override def apply(event: APIGatewayProxyEvent, context: Context, callback: Callback[APIGatewayProxyResult]): Unit = ???
}

object MyFirstAsyncLambda extends AsyncAPIGatewayProxyHandler {
  @js.annotation.JSName("apply")
  override def apply(event: APIGatewayProxyEvent, context: Context): js.Promise[APIGatewayProxyResult]  = ???
}
