Each time we want to create an account, we must wait until the verification email is sent. Then, we should click on the link to verify the account.

This is a very long and tedious process, especially during testing.

We can solve it using one of the following ways:

• Add an environment variable named REQUIRE_EMAIL_VERIFICATION and act according to its value.
• Setup a new container that runs mailhog as an SMTP testing server

Problem

in backend/authentication/router.js:

authRouter.post('/register', schemaValidator(registerSchema), async (req, res) => {
    if (await User.findOne({ where: { email: req.body.email } })) {
        throw new ForbiddenError("Email already in use");
    }

    const user = await User.create({
        ...req.body,
        password: await hash(req.body.password)
    });

    const verificationToken = await VerificationToken.create({
        content: generateVerificationToken(user.id)
    });

    await sendMail(verificationEmail(req.body.email, verificationToken));

    res.json(user);
});

If the email was not sent successfully, we'll have an obsolete user account in the database.

Possible Solutions

Transaction rollback

We can include the database query in a postgres transaction and simply rollback it if we fail to send the email.

Explicit delete query

We can explicitly issue a delete query if the email was not sent.

I am trying to run the project and backend server is giving me

 Server is running on port undefined

we need to specify the default port without depending on .env value or throw exception to user and don't start service
