Node.js and Nodemailer: Can we attached PDF documents to emails?

Question

I am wanting to attach a PDF document using nodemailer and node.js, however, the only examples I am finding for attachments with nodemailer is with .txt files (here).

Does anyone know if PDF document attachment is supported with nodemailer?

Initially it appears a PDF can be attached, yet the PDF file that arrives through the email appears to be damaged (see image).

Code: (Adapted from Mahesh's answer)

fs.readFile('/filePath/fileName.pdf', function (err, data) {
if (err) throw err;                                                  
var mailOptions = {
    from: 'Test <formEmail@gmail.com>', // sender address                                   
    to: 'toPersonName <toEmail@gmail.com>', // list of receivers                                 
    subject: 'Attachment', // Subject line                                                 
    text: 'Hello world attachment test', // plaintext body                                                 
    html: '<b>Hello world attachment test HTML</b>', // html body                                               
    attachments: [
        {
            filename: 'fileName.pdf',                                         
            contentType: 'application/pdf'
        }]
};

// send mail with defined transport object                                                 
transporter.sendMail(mailOptions, function(error, info){
    if(error){
        return console.log(error);
    }
    console.log('Message sent: ' + info.response);
});
console.log(data);
});

Answer 1

Yes you can. You have to add the path of the file which you are trying to attach.

transporter.sendMail({
  from: 'foo@bar.com',
  to: 'bar@foo.com',
  subject: 'An Attached File',
  text: 'Check out this attached pdf file',
  attachments: [{
    filename: 'file.pdf',
    path: 'C:/Users/Username/Desktop/somefile.pdf',
    contentType: 'application/pdf'
  }],
  function(err, info) {
    if (err) {
      console.error(err);
      res.send(err);
    } else {
      console.log(info);
      res.send(info);
    }
  }
});
