How can i access signup function elements from verify function? - node.js

Question

I'm new to website building. I am using node js, express, and express-handlebars. I have 3 hbs page file called signup, verify, and login. I am trying to check if signup page has any errors using exports.signup and then if it's alright then rendering verify page and authenticating it using otp. Now my problem is I need to enter signup page values from verify page in the database after user is verified. How can I get signup page values from exports.signup and use it in exports.verify function?
This works to check in signup page:
exports.signup = (req, res) => { console.log(req.body);
const { name, email, password, passwordConfirm } = req.body;
db.query("select email from test where email=?",[email],async (error, results) => {
if (error) {
console.log(error);
}
if (results.length > 0) {
return res.render("signup", {
message: "The email is already in use",
});
} else if (password !== passwordConfirm) {
return res.render("signup", {
message: "Passwords do not match",
});
}
let hashedPassword = await bcrypt.hash(password, 8);
console.log(hashedPassword);
var digits = "0123456789";
let OTP = "";
for (let i = 0; i < 6; i++) {
OTP += digits[Math.floor(Math.random() * 10)];
}
let transporter = nodemailer.createTransport({
service: "gmail",
auth: {
user: process.env.GMAIL,
pass: process.env.GMAIL_PASSWORD,
},
});
let mailOptions = {
from: "checkmate.sdp#gmail.com",
to: email,
subject: "Verification code for Checkmate profile.",
text: "Your OTP is : " + OTP,
};
transporter.sendMail(mailOptions, function (error, info) {
if (error) {
console.log(error);
} else {
console.log("Email sent: " + info.response);
res.render("verify");
}
});
}
);
};
This verifies the user and enters values in database: (I haven't added anything here yet)
exports.verify = (req, res) => {
console.log(req.body);
};

Just an overview for you
signup.js
'use-strict';
exports.signup = (params) => { console.log("Hit", params) }
controller.js
'use-strict';
var signup = require('./signup');
var http = require('http');
// you can now access the signup function,
signup.signup({username: 'test', password: 'test'})
Looks like you want this to be an HTTP endpoint reciever,
depending on what library youre using, example with Koa route
Backend--
signup.js
var route = require('koa-route');
exports.init = (app) => {
app.use(route.post('/signup', signup));
}
async function signup(ctx) {
var body = ctx.request.body;
//operate
}
Frontend --
$.ajax({
url: "/signup",
type: "post",
data: JSON.stringify({username: 'get from html', password: 'get from html'})
});
