Once I add the following code to my Angular project I get the 'os.networkInterfaces is not a function', but I do not know how to solve this and still use Nodemailer.

location: index.js - const networkInterfaces = (module.exports.networkInterfaces = os.networkInterfaces());

var nodemailer = require('nodemailer');

let transporter = nodemailer.createTransport({
 host: 'smtp.hostinger.com',
  port: 453,
  auth: {
    user: 'xx',
    pass: 'xxx'
  }
});
let mailOptions = {
  from: 'ixxx',
  to: 'xxxx@xx.com',
  subject: 'Sending Email using Node.js',
  text: 'That was easy!'
};

appreciate the help!
