Noze.io is an attempt to carry over the Node.js ideas into pure Swift. It uses libdispatch for event-driven, non-blocking I/O. Noze.io is built around type-safe back-pressure aware pull-streams (using Swift generics) operating on batches of items. Instead of working with just bytes, deal with batches of Unicode lines or database records or HTML responses or - you get the idea. Be efficient: Stream everything and ßatch.

A focus is to keep the API similar to Node. Not always possible - Swift is not JavaScript - but pretty close. It comes with rechargeables included, Noze.io is self-contained and doesn't require any extra dependencies. No extra C modules, pure Swift.
Haz awezome modules such as: cows, leftpad, express, or redis.

Noze.io works in Cocoa environments as well as on Linux. It uses Swift 3 on macOS and Swift 3.0.1 on Linux. Head over to our Start page for install instructions.

Is it a good idea? You tell us. Not sure, but we think it might be, because: a) While Swift looks like JavaScript, it is actually a very high performance, statically typed and AOT-compiled language, b) Code often looks better in Swift, mostly due to the trailing-closure syntax, c) No monkey patching while still providing extensions. There are cons too.

Shows us some code!

There is a reasonably large collection of simple, focused: Noze.io examples. But here you go, the "standard" Node example, a HelloWorld httpd:

import http

http.createServer { req, res in 
  res.writeHead(200, [ "Content-Type": "text/html" ])
  res.end("<h1>Hello World</h1>")
}
.listen(1337)

An echo daemon, just piping the in-end of a socket into its own out-end:

import net

net.createServer { sock in
  sock.write("Welcome to Noze.io!\r\n")
  sock | sock
}
.listen(1337)
