Prompt a csv file to download as pop up using node.js and node-csv-parser (node module)

Question

Recently I have started working with node.js. While going through a requirement in one of my projects I am facing an issue where I should be able to write some data to a csv

Answer 1

Manish Kumar's answer is spot on - just wanted to include a Express 4 syntax variant to accomplish this:

function(req, res) {
  var csv = GET_CSV_DATA // Not including for example.

  res.setHeader('Content-disposition', 'attachment; filename=testing.csv');
  res.set('Content-Type', 'text/csv');
  res.status(200).send(csv);

}
