A small, unopinionated "don't get into my way" / "I don't wanna wait"
asynchronous web framework for Swift.
With a strong focus on replicating the Node APIs in Swift.
But in a typesafe, and fast way.
This repository contains examples for Macro.swift.
Single file examples can be either run as scripts using
swift-sh
(install using a simple brew install mxcl/made/swift-sh),
from within Xcode or via swift run.
This also contains an example for deploying to AWS Lambda: express-simple-lambda.
Raw HTTP server w/o Express extras (middleware, templates).

There is an AWS Lambda variant of this (with minor adjustments): express-simple-lambda.
Use the simpler connect module, instead of express.
Probably no need to do this in the real world, just use MacroExpress.
Single source file with a static index.html plus images.
