Hello Dancers,

Is it possible to print web page output directly using Dancer2?

I'm using Text::CSV_XS to output DB data as CSV like so:

while ( my $row = $sth->fetch ) { $csv->print ( $io, $row ); }

where $io is a file handle, socket, etc.

At the moment, I'm creating a temp file, writing the data, and then using send_file to dispatch the data. Ideally I'd like to just print it straight to the web output, but (e.g.) setting $io to *STDOUT does not work, and there is no serialiser for csv or plain text.

Is there a shortcut that I'm missing?

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; }; -- C.
