=head1 NAME
Mojo::Server::Morbo - Tonight at 11...DOOOOOOOOOOOOOOOM!
=head1 SYNOPSIS
use Mojo::Server::Morbo;
my $morbo = Mojo::Server::Morbo->new;
$morbo->run('/home/sri/myapp.pl');
=head1 DESCRIPTION
L<Mojo::Server::Morbo> is a full featured, self-restart capable non-blocking
I/O HTTP and WebSocket server, built around the very well tested and reliable
L<Mojo::Server::Daemon>, with IPv6, TLS, SNI, UNIX domain socket, Comet (long
polling), keep-alive and multiple event loop support. Note that the server uses
signals for process management, so you should avoid modifying signal handlers in
your applications.
To start applications with it you can use the L<morbo> script.
$ morbo ./myapp.pl
Server available at http://127.0.0.1:3000
For better scalability (epoll, kqueue) and to provide non-blocking name
resolution, SOCKS5 as well as TLS support, the optional modules L<EV> (4.0+),
L<Net::DNS::Native> (0.15+), L<IO::Socket::Socks> (0.64+) and
L<IO::Socket::SSL> (1.94+) will be used automatically if possible. Individual
features can also be disabled with the C<MOJO_NO_NNR>, C<MOJO_NO_SOCKS> and
C<MOJO_NO_TLS> environment variables.
See L<Mojolicious::Guides::Cookbook/"DEPLOYMENT"> for more.
