MacroLambda

AWS Lambda API Gateway Support for Macro and MacroExpress (and all things built on-top).

It allows deployment of arbitrary Macro applications as AWS Lambda functions, including MacroApp endpoints.

Blog article: Deploying Swift on AWS Lambda.

The module is split into the MacroLambda module, which provides the Express runner (Lambda.run(express-app)) and MacroLambdaCore which only links against http and provides the lambda.createServer (the peer to http.createServer).

There is a tutorial on getting started with those things: Create your first HTTP endpoint with Swift on AWS Lambda.

Note: The Swift Lambda Runtime requires Swift 5.2.

Example

import MacroLambda

let app = Express()

app.use(bodyParser.text())

app.post("/hello") { req, res, next in
  console.log("Client posted:", req.body.text ?? "-")
  res.send("Client body sent: \(req.body.text ?? "~nothing~")")
}

app.get { req, res, next in
  res.send("Welcome to Macro!")
}

Lambda.run(app)

Deployment

Using swift lambda (brew install SPMDestinations/tap/swift-lambda):

$ swift lambda deploy -d 5.2
