Answer 1

Best way to download a PDF on REST API call.

var path = require('path');     
var file = path.join(__dirname, 'file.pdf');    
res.download(file, function (err) {
       if (err) {
           console.log("Error");
           console.log(err);
       } else {
           console.log("Success");
       }    
});
