httpd-helloworld

Macro.swift httpd-helloworld

Demonstrates the use of the basic http module. That doesn't feature any middleware or such, but just the basic request/response mechanism.

The server take a client request and returns an HTML response with some information about the submitted request.

Like in Node, IncomingMessage and ServerResponse are regular streams.

Running the Sample

If you have swift-sh installed (brew install swift-sh), just starting the main.swift file works:

$ Sources/httpd-helloworld/main.swift
2020-01-07T17:14:35+0100 notice: Server listening on http://localhost:1337/

Or you can use swift run w/o installing additional software:

$ swift run httpd-helloworld
2020-01-07T21:37:05+0100 notice: Server listening on http://localhost:1337/

Source

#!/usr/bin/swift sh

import Macro // @Macro-swift ~> 0.5.4
http.createServer { req, res in
    // log request
    console.log("\(req.method) \(req.url)")

    // set content type to HTML
    res.writeHead(200, [ "Content-Type": "text/html" ])
    
    // write some HTML
    res.write("<h1>Hello Client: \(req.url)</h1>")

    res.write("<table><tbody>")
    for ( key, value ) in req.headers {
        res.write("<tr><td><nobr>\(key)</nobr></td><td>\(value)</td></tr>")
    }
    res.write("</tbody></table>")

    // finish up
    res.end()
}
.listen(1337, "0.0.0.0") { server in
    console.log("Server listening on http://0.0.0.0:1337/")
}
