You set the content type and return your output as a string.

Something like this:

    get '/data.csv' => sub {
	my $output = '';
        while ( my $row = $sth->fetch ) {
            # TODO: append to $output instead of printing
        }

        content_type 'text/csv';
        return $output;
    };
