NAME

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

SYNOPSIS

9         use Mojo::Server::Daemon;
10
11         my $daemon = Mojo::Server::Daemon->new(listen => ['http://*:8080']);
12         $daemon->unsubscribe('request')->on(request => sub {
13           my ($daemon, $tx) = @_;
14
15           # Request
16           my $method = $tx->req->method;
17           my $path   = $tx->req->url->path;
18
19           # Response
20           $tx->res->code(200);
21           $tx->res->headers->content_type('text/plain');
22           $tx->res->body("$method request for $path!");
23
24           # Resume transaction
25           $tx->resume;
26         });

DESCRIPTION

30       Mojo::Server::Daemon is a full featured, highly portable non-blocking
31       I/O HTTP and WebSocket server, with IPv6, TLS, SNI, Comet (long
32       polling), keep-alive and multiple event loop support.
33
34       For better scalability (epoll, kqueue) and to provide non-blocking name
35       resolution, SOCKS5 as well as TLS support, the optional modules EV
36       (4.0+), Net::DNS::Native (0.15+), IO::Socket::Socks (0.64+) and
37       IO::Socket::SSL (2.009+) will be used automatically if possible.
38       Individual features can also be disabled with the "MOJO_NO_NNR",
39       "MOJO_NO_SOCKS" and "MOJO_NO_TLS" environment variables.

EVENTS

51       Mojo::Server::Daemon inherits all events from Mojo::Server.
52

ATTRIBUTES

54       Mojo::Server::Daemon inherits all attributes from Mojo::Server and
55       implements the following new ones.
56
57   acceptors
58         my $acceptors = $daemon->acceptors;
59         $daemon       = $daemon->acceptors(['6be0c140ef00a389c5d039536b56d139']);
60
61       Active acceptor ids.
62
63         # Check port
64         mu $port = $daemon->ioloop->acceptor($daemon->acceptors->[0])->port;
65
66   backlog
67         my $backlog = $daemon->backlog;

77       getting closed, defaults to the value of the "MOJO_INACTIVITY_TIMEOUT"
78       environment variable or 15. Setting the value to 0 will allow
79       connections to be inactive indefinitely.

118         $daemon->listen(['http://*:3000', 'https://*:4000']);

120         # Use a custom certificate and key
121         $daemon->listen(['https://*:3000?cert=/x/server.crt&key=/y/server.key']);
122
123         # Domain specific certificates and keys (SNI)
124         $daemon->listen(
125           ['https://*:3000?example.com_cert=/x/my.crt&example.com_key=/y/my.key']);

229         # Run multiple web servers concurrently
230         my $daemon1 = Mojo::Server::Daemon->new(listen => ['http://*:3000'])->start;

232         Mojo::IOLoop->start unless Mojo::IOLoop->is_running;

237       Stop accepting connections through "ioloop".
238

DEBUGGING

240       You can set the "MOJO_SERVER_DEBUG" environment variable to get some
