How to pass variable to html template in Nodemailer?

To pass variable to html template in Nodemailer, we put them in the context property.

For instance, we write

const mailOptions = {
  from: "abc@gmail.com",
  to: "username@gmail.com",
  subject: "Sending email",
  template: "yourTemplate",
  context: {
    username,
    whatever: variable,
  },
};

const info = await transporter.sendMail(mailOptions);

to call sendMail with mailOptions to send the email message.

We set the context property to an object with the template variables to interpolate them in the template.
