Hi Andrew,
Thanks for your quick response. I tried your first option.
Say, i have data from database in array called results,
for(var i = 0; i < results.length; i++) {
body = '';
body = results[i]+'\n';
res.write(body);
}
res.setHeader('Content-disposition', 'attachment;
filename='sample.csv');
res.setHeader('Content-type', 'text/csv');
res.end('');
I want to write data in chunks since my array is very big. I used
res.write() for this. By doing this my response is written directly to
browser
and file download option is not asked. How can i solve this?
