Mojo::IOLoop::Server - Non-blocking TCP and UNIX domain socket server

  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;
  # Start reactor if necessary
  $server->reactor->start unless $server->reactor->is_running;

Mojo::IOLoop::Server accepts TCP/IP and UNIX domain socket connections for Mojo::IOLoop.

Mojo::IOLoop::Server inherits all events from Mojo::EventEmitter and can emit the following new ones.

  $server->on(accept => sub {
    my ($server, $handle) = @_;
    ...
  });
Emitted for each accepted connection.

Mojo::IOLoop::Server implements the following attributes.

  my $reactor = $server->reactor;
  $server     = $server->reactor(Mojo::Reactor::Poll->new);
Low-level event reactor, defaults to the "reactor" attribute value of the global Mojo::IOLoop singleton. Note that this attribute is weakened.

Mojo::IOLoop::Server inherits all methods from Mojo::EventEmitter and implements the following new ones.

  my $port = Mojo::IOLoop::Server->generate_port;
Find a free TCP port, primarily used for tests.

  my $handle = $server->handle;
Get handle for server, usually an IO::Socket::IP object.

  my $bool = $server->is_accepting;
Check if connections are currently being accepted.

  $server->listen(port => 3000);
  $server->listen({port => 3000});
Create a new listen socket. Note that TLS support depends on IO::Socket::SSL (2.009+).
These options are currently available:
address
  address => '127.0.0.1'
    
Local address to listen on, defaults to 0.0.0.0.
backlog
  backlog => 128
    
Maximum backlog size, defaults to "SOMAXCONN".
fd
  fd => 3
    
File descriptor with an already prepared listen socket.
path
  path => '/tmp/myapp.sock'
    
Path for UNIX domain socket to listen on.
port
  port => 80
    
Port to listen on, defaults to a random port.
reuse
  reuse => 1
    
Allow multiple servers to use the same port with the "SO_REUSEPORT" socket option.
single_accept
  single_accept => 1
    
Only accept one connection at a time.
tls
  tls => 1
    
Enable TLS.
tls_ca
  tls_ca => '/etc/tls/ca.crt'
    
Path to TLS certificate authority file.
tls_cert
  tls_cert => '/etc/tls/server.crt'
  tls_cert => {'mojolicious.org' => '/etc/tls/mojo.crt'}
    
Path to the TLS cert file, defaults to a built-in test certificate.
tls_ciphers
  tls_ciphers => 'AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH'
    
TLS cipher specification string. For more information about the format see <https://www.openssl.org/docs/manmaster/apps/ciphers.html#CIPHER-STRINGS>.
tls_key
  tls_key => '/etc/tls/server.key'
  tls_key => {'mojolicious.org' => '/etc/tls/mojo.key'}
    
Path to the TLS key file, defaults to a built-in test key.
tls_protocols
  tls_protocols => ['foo', 'bar']
    
ALPN protocols to negotiate.
tls_verify
  tls_verify => 0x00
    
TLS verification mode.
tls_version
  tls_version => 'TLSv1_2'
    
TLS protocol version.

  my $port = $server->port;
Get port this server is listening on.

  $server->start;
Start or resume accepting connections.

  $server->stop;
Stop accepting connections.
