How to send a HTML file with Nodemailer

In my node web application, i used nodemailer to sent emails.

.then(user => {
            const mailOptions = {
                from: "Mohammad.front.dev@gmail.com",
                to: user.email,
                subject: "Reset Password",
                html: `
                    <html>
                    <head>
                        <meta charset="utf-8" />
                        <style>
                            body, * {
                                direction: ltr;
                            }
                        </style>
                    </head>
                    <body>
                        <h1>You've requested a password reset!</h1>
                        <h3>
                            Click this <a href="http://localhost:8000/new-password/${token}">Link</a> to set a new password.
                        </h3>
                    <body>
                    </html>
                `
            };
            req.flash("info", "Checkout your email for reset password link.");
            res.redirect("/products");
            transporter.sendMail(mailOptions, (error, info) => {
                if(error) console.log(error);
                else console.log(info);
            });
...

I want to send a html reversed file instead of writing all that stuff in a js file. How do i do this?

Solution

You can just read the content from the HTML file to the variable and use this variable in mailOptions
