This will allow you to send emails using smtpTransport via nodemailer

Install emailIt package to your machine using this command,

  npm i emailit

emailit(template, fileFormat, mailDetails, templateData, callback);

• template : Name of the template you wish to render in email;

• fileFormat : Format of the file you are sending. eg: 'hbs', 'pug' NOTE: If the template format is html, keep the fileFormat param to hbs and also, update your actual template format. Because hbs format renders the required template and returns an html file

• mailDetails: -recepient: (email address of the receiver), -sender: (email address of the sender), -subject: (Subject of the email),

• templateData: (relevant template data that your templates need dynamically),

• template : Name of the template you wish to render in email;

• callback: A callback function;

    if(err) {
      console.log('Sending email Failed');
    } else {
