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']);
         $daemon->unsubscribe('request')->on(request => sub ($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, SNI, Comet (long polling), keep-alive and multiple event
       loop support.

       For better scalability (epoll, kqueue) and to provide non-blocking name resolution, SOCKS5
       as well as TLS support, the optional modules EV (4.32+), Net::DNS::Native (0.15+),
       IO::Socket::Socks (0.64+) and IO::Socket::SSL (2.009+) will be used automatically if
       possible. Individual features can also be disabled with the "MOJO_NO_NNR", "MOJO_NO_SOCKS"
       and "MOJO_NO_TLS" environment variables.

       See "DEPLOYMENT" in Mojolicious::Guides::Cookbook for more.

SIGNALS

       The Mojo::Server::Daemon process can be controlled at runtime with the following signals.

   INT, TERM
       Shut down server immediately.

EVENTS

       Mojo::Server::Daemon inherits all events from Mojo::Server.

ATTRIBUTES

       Mojo::Server::Daemon inherits all attributes from Mojo::Server and implements the
       following new ones.

   acceptors
         my $acceptors = $daemon->acceptors;
         $daemon       = $daemon->acceptors(['6be0c140ef00a389c5d039536b56d139']);

       Active acceptor ids.

         # Check port
         mu $port = $daemon->ioloop->acceptor($daemon->acceptors->[0])->port;

   backlog
         my $backlog = $daemon->backlog;
         $daemon     = $daemon->backlog(128);

       Listen backlog size, defaults to "SOMAXCONN".

   inactivity_timeout
         my $timeout = $daemon->inactivity_timeout;
         $daemon     = $daemon->inactivity_timeout(5);

       Maximum amount of time in seconds a connection with an active request can be inactive
       before getting closed, defaults to the value of the "MOJO_INACTIVITY_TIMEOUT" environment
       variable or 30. Setting the value to 0 will allow connections to be inactive indefinitely.

   ioloop
         my $loop = $daemon->ioloop;
         $daemon  = $daemon->ioloop(Mojo::IOLoop->new);

       Event loop object to use for I/O operations, defaults to the global Mojo::IOLoop
       singleton.

   keep_alive_timeout
         my $timeout = $daemon->keep_alive_timeout;
         $daemon     = $daemon->keep_alive_timeout(10);

       Maximum amount of time in seconds a connection without an active request can be inactive
       before getting closed, defaults to the value of the "MOJO_KEEP_ALIVE_TIMEOUT" environment
       variable or 5. Setting the value to 0 will allow connections to be inactive indefinitely.

   listen
         my $listen = $daemon->listen;
         $daemon    = $daemon->listen(['https://127.0.0.1:8080']);

       Array reference with one or more locations to listen on, defaults to the value of the
       "MOJO_LISTEN" environment variable or "http://*:3000" (shortcut for
       "http://0.0.0.0:3000").

         # Listen on two ports with HTTP and HTTPS at the same time
         $daemon->listen(['http://*:3000', 'https://*:4000']);

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

         # Domain specific certificates and keys (SNI)
         $daemon->listen(
           ['https://*:3000?example.com_cert=/x/my.crt&example.com_key=/y/my.key']);

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