NAME
Mojo::IOLoop::Server - Non-blocking TCP server
SYNOPSIS
use Mojo::IOLoop::Server;
# Create listen socket
my $server = Mojo::IOLoop::Server->new;
$server->on(accept => sub {
my ($server, $handle) = @_;
...
});
$server->listen(port => 3000);
# Start and stop accepting connections
$server->start;
$server->stop;
DESCRIPTION
Mojo::IOLoop::Server accepts TCP connections for Mojo::IOLoop.
EVENTS

"accept"
$server->on(accept => sub {
my ($server, $handle) = @_;
