A modern programming language that makes developers happier.

kotlinlang

Hello :kodee-happy:

I’ve built an experimental library for running Ktor on AWS Lambda:

<https://github.com/jsoizo/ktor-server-lambda|github.com/jsoizo/ktor-server-lambda>

It implements a Ktor server engine that processes <https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-develop-integrations-lambda.html|Lambda events> without opening a socket, so you can use Ktor routing and plugins as usual.

There are two ways to run it:
• *JVM*: a KtorRequestStreamHandler subclass on the managed Java runtime, with support for <https://docs.aws.amazon.com/lambda/latest/dg/snapstart.html|SnapStart> priming.
• *Kotlin/Native*: a custom runtime that polls the <https://docs.aws.amazon.com/lambda/latest/dg/runtimes-api.html|Lambda Runtime API.>
Both share the same engine and event codecs, supporting API Gateway, Function URLs, and ALB.

It’s still very early, but I’d love to hear what you think of the approach :kodee_walking:

You might be interested to know that we're looking at <https://github.com/ktorio/ktor-klip/blob/b4938ece7a795d70ca8f9ab70306b40938240ca5/proposals/0008-server-function-ux.md#serverless-functions|introducing proper support for serverless functions in Ktor>.  It's just an idea right now, we haven't tried anything out yet, so you might be able to provide some good insight there.
