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 NIOSSL 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 2 has been tested with Swift 5. If you are using Swift 4, please use Kitura-NIO 1. See the release history for details.
- Port Listening
- HTTP Server support (request and response)
- Basic HTTP client support
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 application:
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 makes 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!
- Clone this repository.
$ git clone https://github.com/IBM-Swift/Kitura-NIO && cd Kitura-NIO
- 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.
We'd really love to hear feedback from you.

Help us keep the lights on
2.2.0 - Jul 29, 2019
- A nasty race condtion related to WebSocket upgrade has been removed (#217)
ClientRequest: HTTP credentials will no longer be included in the
ClientRequest.urlproperty. This is a small behaviour change (#208)
- The creation of
HTTPServerRequestobjects is now permissible only on the
EventLoopon which the underlying HTTP request arrived (#215)
ClientRequest: new request headers added for parity with Kitura-net (#213)
ClientResponse.statusis now updated to reflect the value of
2.1.1 - Jun 5, 2019
- Falling back to building HTTPServerRequest.urlURL using String concatenation instead of URLComponents. This also includes a change to
ClientRequestthat makes sure we don't percent-encode a URL string twice. (https://github.com/IBM-Swift/Kitura-NIO/pull/199)
2.1.0 - May 24, 2019
- Allow Kitura-NIO to only listen on one network address (#205). Kitura listens on every available address/interface. This feature allows Kitura to listen on only on interface (only one network address)
2.0.5 - May 17, 2019
- Upgrade to swift-nio 2.1 (#204)
2.0.4 - May 14, 2019
- Fix for a WebSocket upgrade failure in Safari based clients(https://github.com/IBM-Swift/Kitura-NIO/pull/203)
