Simple Example

In this example, we take advantage of the Dub package manager's single-file SDL syntax to declare HandyHttpd as a dependency. For this example, we'll call this my_server.d.

#!/usr/bin/env dub
/+ dub.sdl:
	dependency "handy-httpd" version="~>7"
+/
import handy_httpd;

void main() {
	new HttpServer((ref ctx) {
		if (ctx.request.url == "/hello") {
			ctx.response.writeBodyString("Hello world!");
		} else {
			ctx.response.setStatus(HttpStatus.NOT_FOUND);
		}
	}).start();
}

To start the server, just mark the script as executable, and run it:

chmod +x my_server.d
./my_server.d

And finally, if you navigate to http://localhost:8080/hello, you should see the Hello world! text appear.
