% cat > app.cgi
package main;
my $app = sub {
return [ 200, [ "Content-Type", "text/html" ], [ "Hello" ] ];
};
Plack::Handler::CGI->new->run($app);
% cat `perldoc -l Plack::Handler::CGI` app.cgi > app_bundled.cgi
Now app_bundled.cgi works as a CGI script, no dependencies out of the
core (Plack::Handler::CGI only requires strict.pm and IO::Handle). FTP
that file, chmod +x it and it works as a CGI script on any host.
Although more realistically, take Mojolicious::Lite as an example,
since I want to point out PSGI doesn't really mean Plack and whichever
frameworks that support PSGI can come into play:
$ cat > myapp.pl
use Mojolicious::Lite;
get '/' => sub {
my $self = shift;
$self->render(text => "Hi");
};
app->start;
The myapp.pl can work as a CGI, but also as a PSGI handler if you
deploy to platforms that only supports PSGI apps and *not* CGI, such
as Heroku, DotCloud and Stackato.
