    host: 'smtp.gmail.com', 
    port: 465, 
    auth: { 
     user: '[email protected]', 
     pass: 'ashbdhbedbudu.' 
    } 
})); 

transporter.sendMail({ 
    from: "[email protected]", 
    subject:" hello ji " , 
    text: "I would like to write dialogue", 
    attachments:[ 
     { 
      'filename':'link.txt',

     } 
    ], 
    to: "[email protected]" 
}, function(error, info) { 
    if (error) { 
     return console.log(error); 
    }
