NWHTTPProtocol

An HTTP protocol parser (aka NWProtocolFramer) for the Apple Network.framework.

How it works is described in my blog entry: Intro to Network.framework Servers.

Network.framework requires iOS 13+ / macOS 10.15+.

This is intentionally kept very simple and basic. E.g. it does not define Swift types for HTTP requests and the like, but puts the status/request/URI in plain Message metadata fields.

The protocol is just wrapping the (embedded) http_parser.c/h developed as part of the Node.js project.

NWHTTPServer

It also includes NWHTTPServer, a very simple HTTP server based on the NWHTTPProtocol.

Example:

let server = HTTPServer { request, response in
    print("Received:", request)
    try response.send("Hello!\n")
}
server.run()

Production

Note that for production use I’d suggest to not use a protocol framer for HTTP. Instead hookup http_parser.c to plain Network.framework (as shown for echo in the blog article). At least that’s what I do in production apps. NW protocol framing isn’t really required for http_parser.c, because that already does all the framing necessary and can be fed asynchronously).

NWHTTPProtocol is brought to you by ZeeZide. We like feedback, GitHub stars, cool contract work, presumably any form of praise you can think of.
