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.

MacroExpress is a more capable variant of µExpress. The goal is still to keep a small core, but add some Noze.io modules and concepts.

MacroExpress adds the web framework components to Macro (kinda like Express.js adds to Node.js).

MacroLambda has the bits to directly deploy MacroExpress applications on AWS Lambda. MacroApp adds a SwiftUI-style declarative DSL to setup MacroExpress routes.

What does it look like?

The Macro Examples package contains a few examples which all can run straight from the source as swift-sh scripts.

#!/usr/bin/swift sh
import MacroExpress // @Macro-swift

let app = express()
app.use(serveStatic(__dirname() + "/public"))

app.get("/hello") { req, res, next in
  res.send("Hello World!")
app.get { req, res, next in

Release Notes

3 weeks ago

Enforce use of Swift 5.5 enabled Macro. Changed Package.swift to 5.2 syntax (on a quest to be as WET as possible).

Removed support for Swift 5.0 and 5.1, because Apple:

We didn’t do it because it was required, instead that it felt appropriate
