This was my very first project, for my family business, having the advantage of understanding the business model, I was able to model it entirely to my preference.
It took me over 4 months and I learned a lot.
In this case I used MERN stack and a few libraries which helpeded me to handle mailing suscriptions, checkouts, mongo database and also security.

The backend is not online but it is on my github repository and it's fully functional, so feel free to take a look for yourself or use it for personal purpose.

Password reset code:

app.post("/backend/forgot-password", async (req, res) => {
  try {
    const { username } = req.body;

    // Find the user based on the provided username or email
    const user = await User.findOne({ username });

    if (!user) {
      return res.status(404).json({ mensaje: "Usuario no encontrado" });
    }

    const token = jwt.sign({ userId: user._id }, process.env.JWT_SECRET, {
      expiresIn: "1h",
    });

    const source = fs.readFileSync(
      "./mail-templates/forgot-password.html",
      "utf-8"
    );

    const template = handlebars.compile(source);

    const replacements = {
      username: username,
      resetLink: `http://www.peludos.com/reset-password/${token}`,
    };

    const htmlToSend = template(replacements);

    const transporter = nodemailer.createTransport({
      service: "Gmail",
      auth: {
        user: "peludos@gmail.com",
        pass: process.env.NODE_MAILER,
      },
    });

    const mailOptions = {
      from: "peludos..@gmail.com",
      to: user.username,
      subject: "Recuperar contraseña",
      html: htmlToSend,
    };

    transporter.sendMail(mailOptions, (error, info) => {

  } catch (error) {
    if (error.name === "TokenExpiredError") {
      return res.status(400).json({ mensaje: "El token ha expirado" });
    }
    console.error(error);
    res.status(500).json({ mensaje: "Error en el servidor" });
