# Net::Async::FastCGI::PSGI(3pm)

use "PSGI" applications with "Net::Async::FastCGI"

## NAME

"Net::Async::FastCGI::PSGI" - use "PSGI" applications with "Net::Async::FastCGI"

## SYNOPSIS

```
   use Net::Async::FastCGI::PSGI;
   use IO::Async::Loop;
   my $loop = IO::Async::Loop->new;
   my $fcgi = Net::Async::FastCGI::PSGI->new(
      port => 12345,
      app => sub {
         my $env = shift;
         return [
            200,
            [ "Content-Type" => "text/plain" ],
            [ "Hello, world!" ],
         ];
      },
   );
   $loop->add( $fcgi );
   $loop->run;
```

## DESCRIPTION

This subclass of Net::Async::FastCGI allows a FastCGI responder to use a PSGI application to respond to requests. It acts as a gateway between the FastCGI connection from the webserver, and the `"PSGI"` application. Aside from the use of `"PSGI"` instead of the `"on_request"` event, this class behaves similarly to `"Net::Async::FastCGI"`.

## PARAMETERS

The following named parameters may be passed to `"new"` or `"configure"`:

- app =\> CODE

  Reference to the actual `"PSGI"` application to use for responding to requests

## PSGI ENVIRONMENT

The following extra keys are supplied to the environment of the `"PSGI"` app:

- "net.async.fastcgi"

  The `"Net::Async::FastCGI::PSGI"` object serving the request

- "net.async.fastcgi.req"

  The Net::Async::FastCGI::Request object representing this particular request

- "io.async.loop"

  The IO::Async::Loop object that the `"Net::Async::FastCGI::PSGI"` object is a member of.
