=head1 NAME
Plack::Handler - Connects PSGI applications and Web servers
=head1 SYNOPSIS
package Plack::Handler::AwesomeWebServer;
sub new {
my($class, %opt) = @_;
...
return $self;
}
sub run {
my($self, $app) = @_;
# launch the AwesomeWebServer and run $app in the loop
}
# then from command line
plackup -s AwesomeWebServer -a app.psgi
=head1 DESCRIPTION
Plack::Handler defines an adapter (connector) interface to adapt
L<plackup> and L<Plack::Runner> to various PSGI web servers, such as
Apache2 for mod_perl and Standalone for L<HTTP::Server::PSGI>.
It is an empty class, and as long as they implement the methods
defined as an Server adapter interface, they do not need to inherit
Plack::Handler.
If you write a new handler for existing web servers, I recommend you
to include the full name of the server module after I<Plack::Handler>
prefix, like L<Plack::Handler::Net::Server::Coro> if you write a
handler for L<Net::Server::Coro>. That way you'll be using plackup
command line option like:
plackup -s Net::Server::Coro
that makes it easy to figure out which web server you're going to use.
=head1 METHODS
=over 4
=item new
$server = FooBarServer->new(%args);
Creates a new adapter object. I<%args> can take arbitrary parameters
to configure server environments but common parameters are:
=over 8
=item port
Port number the server listens to.
=item host
Address the server listens to. Set to undef to listen any interface.
=back
=item run
$server->run($app);
Starts the server process and when a request comes in, run the PSGI
application passed in C<$app> in the loop.
=item register_service
$server->register_service($app);
Optional interface if your server should run in parallel with other
event loop, particularly L<AnyEvent>. This is the same as C<run> but
doesn't run the main loop.
