Kitura-NIO

Kitura-NIO is a SwiftNIO based networking library for Kitura. Kitura-NIO adopts the same API as KituraNet, making the transition from KituraNet to Kitura-NIO seamless. While Kitura-NIO shares some code with Kitura-Net, the core comprising of HTTPServer, ClientRequest/ClientResponse and TLS support have been implemented using SwiftNIO. Kitura-NIO uses NIOOpenSSL for TLS support.

We expect most of our users to require higher level concepts such as routing, templates and middleware, these are not provided in Kitura-NIO, if you want to use those facilities you should be coding at the Kitura level, for this please see the Kitura project. Kitura-NIO, like Kitura-net, underpins Kitura which offers a higher abstraction level to users.

Kitura-NIO works with Swift 4.2. It is also being tested with the development binaries for Swift 5.

Features

  • Port Listening
  • HTTP Server support (request and response)

Using Kitura-NIO

With Kitura 2.5 and future releases, to run on top of Kitura-NIO (instead of Kitura-Net) all you need to do is set an environment variable called KITURA_NIO before building your Kitura appilication:

    export KITURA_NIO=1 && swift build

If you have already built your Kitura application using Kitura-Net and want to switch to using KITURA_NIO, you need to update the package before building:

    export KITURA_NIO=1 && swift package update && swift build

Using the environment variable we make sure that only one out of Kitura-NIO and Kitura-Net is linked into the final binary.

Please note that though Kitura-NIO has its own GitHub repository, the package name is KituraNet. This is because the Kitura-NIO and Kitura-Net are expected to provide identical APIs, and it make sense if they share the package name too.

Contributing to Kitura-NIO

We’d be more than happy to receive bug reports, enhancement requests and pull requests!

  1. Clone this repository.

$ git clone https://github.com/IBM-Swift/Kitura-NIO && cd Kitura-NIO

  1. Build and run tests.

$ swift test

You may also want to run the tests in parallel: $ swift test --parallel

In some Linux environments, a low open file limit could cause test failures. See this.
