# FCGI::Async(3pm)

use FastCGI with IO::Async

## NAME

"FCGI::Async" - use FastCGI with IO::Async

## SYNOPSIS

```
 use FCGI::Async;
 use IO::Async::Loop;
 my $loop = IO::Async::Loop->new();
 my $fcgi = FCGI::Async->new(
    loop => $loop
    service => 1234,
    on_request => sub {
       my ( $fcgi, $req ) = @_;
       # Handle the request here
    }
 );
 $loop->loop_forever;
```

## DESCRIPTION

This subclass of Net::Async::FastCGI provides a slightly different API; where it can take an argument containing the IO::Async::Loop object, rather than be added as `"Notifier"` object within one. It is provided mostly as a backward-compatibility wrapper for older code using this interface; newer code ought to use the `"Net::Async::FastCGI"` interface directly.

## CONSTRUCTOR

### $fcgi = FCGI::Async-\>new( %args )

Returns a new instance of a `"FCGI::Async"` object.

If either a `"handle"` or `"service"` argument are passed to the constructor, then the newly-created object is added to the given `"IO::Async::Loop"`, then the `"listen"` method is invoked, passing the entire `%args` hash to it.

If either of the above arguments are given, then a `"IO::Async::Loop"` must also be provided:

- loop =\> IO::Async::Loop

  A reference to the `"IO::Async::Loop"` which will contain the listening sockets.
