SocketIO

More information about SocketIO you can find on the website http://socket.io/, or on GitHub https://github.com/LearnBoost/Socket.IO.

EXAMPLE

Below is an example similar to Socket.IO-node example chat. To run this example, you need to make the following simple steps:

1. Clone somewhere https://github.com/LearnBoost/Socket.IO-node.

2. Save the shown .psgi file, changing <$path_to_socket_io> so it points to the Socket.IO-node files.

use Plack::Builder;
use Plack::App::File;
use Plack::Middleware::Static;
use Plack::Middleware::SocketIO;

my $path_to_socket_io = "/path/to/Socket.IO-node";

builder {
    mount '/socket.io/socket.io.js' => Plack::App::File->new(
        file => "$path_to_socket_io/support/socket.io-client/socket.io.js");

    mount '/' => builder {
        enable "Static",
          path => qr/\.(?:js|css|jpe?g|gif|png|html?|js|css|swf|ico)$/,
          root => "$path_to_socket_io/example";

        enable "SimpleLogger", level => 'debug';

        enable "SocketIO", handler => sub {
            my $self = shift;

            $self->on_message(
                sub {
                    my $self = shift;
                    my ($message) = @_;

                    $self->send_broadcast({message => [$self->id, $message]});
                }
            );

            $self->on_disconnect(
                sub {
                    $self->send_broadcast(
                        {announcement => $self->id . ' disconnected'});
                }
            );

            $self->send_message({buffer => []});

            $self->send_broadcast({announcement => $self->id . ' connected'});
        };

        sub {
            [   200,
                ['Content-Type' => 'text/html'],
                ['Open <a href="/chat.html">chat</a>.']
            ];
        };
    };
};

3. Start Twiggy or Fliggy (same as Twiggy but with inlined Flash Policy server)

$ sudo flash-policy-server &
$ twiggy chat.psgi --listen :8080

or

$ fliggy chat.psgi --listen :8080

4. Point your browser to

http://localhost:8080

TLS/SSL

For TLS/SSL a secure proxy is needed. stunnel or App::TLSMe is recommended.

DISCLAIMER

This middleware is in a very beta stage. API will be probably changed.
