NAME
Plack::Middleware - Base class for easy-to-use PSGI middlewareSYNOPSIS
package Plack::Middleware::Foo; use parent qw( Plack::Middleware ); sub call { my($self, $env) = @_; # Do something with $env # $self->app is the original app my $res = $self->app->($env); # Do something with $res return $res; } # then in app.psgi use Plack::Builder; my $app = sub { ... } # as usual builder { enable "Plack::Middleware::Foo"; enable "Plack::Middleware::Bar", %options; $app; };
DESCRIPTION
Plack::Middleware is an utility base class to write PSGI middleware. All you have to do is to inherit from Plack::Middleware and then implement the callback "call" method (or "to_app" method that would return the PSGI code reference) to do the actual work. You can use "$self->app" to call the original (wrapped) application.See Plack::Builder how to actually enable middlewares in your .psgi application file using the DSL. If you do not like our builder DSL, you can also use "wrap" method to wrap your application with a middleware:
use Plack::Middleware::Foo; my $app = sub { ... }; $app = Plack::Middleware::Foo->wrap($app, %options); $app = Plack::Middleware::Bar->wrap($app, %options);
