NAME

Mojo::Server::Daemon - Non-blocking I/O HTTP and WebSocket server

SYNOPSIS

use Mojo::Server::Daemon;

my $daemon = Mojo::Server::Daemon->new(listen => ['http://*:8080']);
$daemon->unsubscribe('request');
$daemon->on(request => sub {
  my ($daemon, $tx) = @_;

  # Request
  my $method = $tx->req->method;
  my $path   = $tx->req->url->path;

  # Response
  $tx->res->code(200);
  $tx->res->headers->content_type('text/plain');
  $tx->res->body("$method request for $path!");

  # Resume transaction
  $tx->resume;
});
$daemon->run;

DESCRIPTION

Mojo::Server::Daemon is a full featured, highly portable non-blocking I/O HTTP and WebSocket server, with IPv6, TLS, Comet (long polling) and multiple event loop support.

Optional modules EV (4.0+), IO::Socket::IP (0.16+) and IO::Socket::SSL (1.75+) are supported transparently through Mojo::IOLoop, and used if installed. Individual features can also be disabled with the MOJO_NO_IPV6 and MOJO_NO_TLS environment variables.

See Mojolicious::Guides::Cookbook for more.

# Listen on IPv6 interface
$daemon->listen(['http://[::1]:4000']);

# Listen on two ports with HTTP and HTTPS at the same time

# Use a custom certificate and key
$daemon->listen(['https://*:3000?cert=/x/server.crt&key=/y/server.key']);

# Or even a custom certificate authority
