Export your sendMail method and import it in your controller.

controller function

let sendMail = require('your nodemailer file').sendMail;
exports.createListing = (req, res) => {
    // Validate request
    if(!req.body.content) {
        return res.status(400).send({
            message: "Fields can not be empty"
        });
    }

    const listing = new Listing({
        title: req.body.title, 
        city: req.body.city,
        street: req.body.street,
        businessname: req.body.businessname,
        description: req.body.description
    });

    listing.save()
    .then(data => {
        sendMail({
        title: req.body.title, 
        city: req.body.city,
        street: req.body.street})
        res.send(data);
    }).catch(err => {
        res.status(500).send({
            message: err.message || "Some error occurred while creating the listing."
        });
    });
};

NodeMailer function

var smtpTransport = nodemailer.createTransport({
        service: 'Gmail',
        port: 465,
        auth: {
          user: 'YOUR_GMAIL_SERVER',
          pass: 'YOUR_GMAIL_PASSWORD'
        }
      });



module.exports.sendmail = (data)=>{
return new Promise((resolve,reject)=>{

      var mailOptions = {
        to: data.email,
        subject: 'ENTER_YOUR_SUBJECT',
        html: `
${data.title}
              
${data.city}
              
${data.street}
`,
              ...
      };





      smtpTransport.sendMail(mailOptions,
        (error, response) => {
          if (error) {
            reject(error);
          } else {
            resolve('Success');
          }
          smtpTransport.close();
        });
});
};
