"Das Haus das Verrückte macht."



**Note** (2021-11-09): It is not recommended to use this for production,

though it still makes a nice demo. The more modern, and quite recommendable,

version of this is [Macro.swift](https://github.com/Macro-swift/Macro),

which is based on SwiftNIO (instead of GCD like Noze.io).



**Noze.io** was an attempt to carry over the [Node.js](http://nodejs.org/)

ideas into *pure* [Swift](http://swift.org).

It uses [libdispatch](https://github.com/apple/swift-corelibs-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 just operating on bytes,

operate on 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.

It includes modules such as

[cows](Sources/cows),

[leftpad](Sources/leftpad),

[express](Sources/express) or

[redis](Sources/redis).



**Noze.io** works in Cocoa environments as well as on Linux.

Head over to our [Start](http://noze.io/start/) page for install instructions.



*Is it a good idea?* You [tell us](http://noze.io/about/).

Not sure, but we think it might be, because:

*a)* While Swift looks *very* much 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 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](Samples)

But here you go, the "standard" Node example, a HelloWorld httpd:

```swift

import http



http.createServer { req, res in 

  res.writeHead(200, [ "Content-Type": "text/html" ])

  res.end("
Hello World
")

}

.listen(1337)

```

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

```swift

import net



net.createServer { sock in

  sock.write("Welcome to Noze.io!\r\n")

  sock | sock

}

.listen(1337)

```

More complex stuff including a 

[Todo-MVC backend](https://github.com/NozeIO/Noze.io/blob/master/Samples/todo-mvc-redis/main.swift)

can be found in the

[Noze.io examples](https://github.com/NozeIO/Noze.io/tree/master/Samples).

With the release of Swift 3 Noze.io drops support for Swift 2.x. If you

are still interested in using it with 2.x, the last release is still available

in the `legacy/swift23` branch on GitHub.



### Status



- We chose the traditional Swift approach:

  Make something barely usable, though demoable,

  and release it with a 3.0 version tag.

  Then hope that the community kicks in and fills open spots.

  Well kinda. It's pretty good already! 😉



- It already has

  [leftpad](Sources/leftpad).

  As well as [cows 🐮](Sources/cows/README.md)!



- Implements primarily the happy path. Errors will error. Presumably this

  will improve over time.



- A huge strength of Node is the npm package environment and the

  myriads 

  of packages available for it.

  Or wait, is it? Well, at least we have

  [leftpad](Sources/leftpad)

  included.

  And we hope that the [Swift package](https://swift.org/package-manager/)

  environment is going to grow as well.



- There are tons of open ends in Noze.io. We welcome contributions of all kinds.
