javascript - node.js Nodemailer array of objects to CSV file as attachment in email -

i'm sending email in node.js using nodemailer module. have array of objects i'm trying turn csv file , attach email. able send email, csv attachment doesn't populate correctly (showing blank). code looks similar following

var nodemailer = require('nodemailer');  // create reusable transporter object using smtp transport     var transporter = nodemailer.createtransport({     service: 'gmail',     auth: {         user: 'gmail.user@gmail.com',         pass: 'userpass'      } });  var data = [{age:24,name:"bob"},{age:35,name:"andy"},...];  var mailoptions = {     from: 'foo@blurdybloop.com', // sender address     to: 'bar@blurdybloop.com', //receiver     subject: 'hello', // subject line     text: 'hello world', // plaintext body     html: '<b>hello world</b>', // html body     attachments: [         {            filename: 'test.csv',         content: data      } };  // send mail defined transport object transporter.sendmail(mailoptions, function(error, info){ if(error){     return console.log(error); } console.log('message sent: ' + info.response); }); 

i'm guessing it's not able read array of objects , works string separated commas?

you should specify content property string. nodemailer doesn't convert files itself. need convert data csv string before sending it. use module to-csv it.
