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

DESCRIPTION

Plack::Handler defines an adapter (connector) interface to adapt plackup and Plack::Runner to various PSGI web servers, such as Apache2 for mod_perl and Standalone for 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 Plack::Handler prefix, like Plack::Handler::Net::Server::Coro if you write a handler for 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.

METHODS

new

  $server = FooBarServer->new(%args);

Creates a new adapter object. %args can take arbitrary parameters to configure server environments but common parameters are:

port

Port number the server listens to.

host

Address the server listens to. Set to undef to listen any interface.

run

  $server->run($app);

Starts the server process and when a request comes in, run the PSGI application passed in $app in the loop.

register_service

  $server->register_service($app);

Optional interface if your server should run in parallel with other event loop, particularly AnyEvent. This is the same as "run" but doesn't run the main loop.
