how to send email confirmation in nodejs and SendGrid? - node.js

Question

I have a NodeJs and ReactJs project, where a user can register and after the user is registered they will get an email to confirm their account.
so now when I register the email is working well. but it works with an email that I set in like this.
function sendMail() {
const msg = {
to: "someoneemail#gmail.com",
from: "myemail#gmail.com",
subject: "a subject",
text: "some text herer",
html: "<strong>and easy to do anywhere, even with Node.js</strong>",
};
sgMail
.send(msg)
.then(() => {
console.log("Email sent");
})
.catch((error) => {
console.error(error);
});
}
module.exports = { sendMail };
I need to remove this to: "someoneemail#gmail.com" a*
nd instead set the user email, the user who to register on this
system
and instead of text: i have to send the token.
so here is the registration part:
router.post("/register", async (req, res) => {
const { fullName, emailAddress, password } = req.body;
const user = await Users.findOne({
where: {
[Op.and]: [{ fullName: fullName }, { emailAddress: emailAddress }],
},
});
if (user) {
res.status(400).send({
error: `some message.`,
});
} else {
bcrypt
.hash(password, 10)
.then((hash) => {
return {
fullName: fullName,
emailAddress: emailAddress,
password: hash,
isVerified: false,
};
})
.then((user) => {
const token = TokenGenerator.generate();
const creator = Verifications.belongsTo(Users, { as: "user" });
return Verifications.create(
{
token,
user: user,
},
{
include: [creator],
}
);
})
.then((verification) => {
console.log("verification", verification);
sendMail();
})
.then(() => res.json("User, Successmessage "));
}
});
but the codes are not in the same file.

Just add the parameters you need to the sendMail function:
function sendMail(user, token) {
const msg = {
to: user.emailAddress,
from: "myemail#gmail.com",
subject: "Sending with SendGrid is Fun",
text: token,
html: `<strong>${token}</strong>`,
};
sgMail
.send(msg)
.then(() => {
console.log("Email sent");
})
.catch((error) => {
console.error(error);
});
}
Also inject the needed parameters in the promises:
.then(async (user) => {
const token = TokenGenerator.generate();
const creator = Verifications.belongsTo(Users, { as: "user" });
await Verifications.create(
{
token,
user: user,
},
{
include: [creator],
}
);
return {user, token};
})
.then(({user, token}) => {
sendMail(user, token);
})
.then(() => res.json("User, Successmessage "));
