Hello

I am trying to use this example for a iot application: 
https://aberba.com/2018/using-vibe-d-web-interface/


The code i use is:

ushort port   =   5504;

void main(char[][] args)
{

 auto router = new URLRouter;
 router.post("/archive", );
 router.get("/archive", );

 auto settings = new HTTPServerSettings;
 settings.port = port;
 settings.bindAddresses = ["::1", "0.0.0.0"];
 listenHTTP(settings, router);

 runApplication();
}


This is fine. But now that we have ~ 100 IoT devices in the 
field, I would like to assign each a new port.




Why? I do not see any reason for that.


to separate the messages from the IoT responses quickly and 
forward them to different programs, and to have the capability 
in hand, so that when later i have an idea to exploit the 
capability, I can also do it.


What you are doing, if I understand you well, is a way of scaling 
the server to handle high amount of traffic.


If that's right, then I'm not sure how the number of PORT is the 
issue. Irrespective of the port, the server resources remains the 
same.


And if that's the case, then you might need a load balancer (or 
use nginx or any of the options I've used in my projects). In 
that case, you run multiple versions of the server in stateless 
environments... scaled up or down on demand.




Been a long while since I wrote some vibe.d tutorials though :)

Ok as Adam said you can do something like this:

void main()
{
immutable ushort startPort = 5500;
import std.range : iota;

foreach (ushort port; iota!(ushort,ushort)(startPort, startPort + 100))
{
auto settings = new HTTPServerSettings;
settings.port = port;
settings.bindAddresses = ["::1", "127.0.0.1"];
listenHTTP(settings, );
}
runApplication();
}

void hello(HTTPServerRequest req, HTTPServerResponse res)
{
import std.conv : to;
res.writeBody(req.fullURL.port.to!string);
}

If you loop this section it should listen to each port. This is 
just a setup loop, it wouldn't actually be wasteful once it is 
running.


(I think, I don't really know vibe super well)

vibe.de multiple ports.

Hello

listenHTTP(settings, router);

runApplication();
}


This is fine. But now that we have ~ 100 IoT devices in the 
field, I would like to assign each a new port. The devices should 
be communicating over HTTP as the vendor software running 
thereupon uses http.


What is the best practice to make a vibe.d server listen to 
multiple ports? Make a loop scanning each loop seems wasteful. Is 
there a function in vibe.d that can take multiple ports, and 
launch a set of threads assigned to each port?


Thank you
