Swift AWS Lambda

This library is designed to allow writing AWS Lambdas using the Swift programming language.

Getting started

1. Create a SwiftPM project and pull SwiftAwsLambda as dependency into your project

import PackageDescription

let package = Package(
    name: "my-lambda",
    products: [
        .executable(name: "MyLambda", targets: ["MyLambda"]),
    ],
    dependencies: [
        .package(url: "https://github.com/swift-server/swift-aws-lambda.git", .upToNextMajor(from: "0.1.0")),
    ],
    targets: [PackageDescription.Target] = [
        .target(name: "MyLambda", dependencies: ["SwiftAwsLambda"]),    
    ]
)

2. Create a main.swift and implement you lambda. typically a lambda is implemented as a closure. For example, a simple lambda for a closure that receives a string payload and replies with the reverse version:

import SwiftAwsLambda

_ = Lambda.run { (context: LambdaContext, payload: String, callback: LambdaStringCallback) in
    callback(.success(String(payload.reversed())))
}

note you can implement 3 types of lambdas:

1. [UInt8] (byte array) based (default): see SwiftAwsLambdaExample
2. String based: see SwiftAwsLambdaStringExample
3. Codable based: see SwiftAwsLambdaCodableExample
