Email verify in sail.js - angularjs

Question

I am trying to make a portal for filling up a form for which an applicant needs to create an account before filling out the form. The only issue is how can I stop from spamming the applicant creating account with fake mail. Is it possible to verify email in sail. I have done this in express using node mailer.
var express = require('express');
var nodemailer= require('nodemailer');
var app = express();
var smtpTransport = nodemailer.createTransport("SMTP", {
service: "Gmail",
auth: {
user: "email",
pass: "pass"
}
});
var rand, mailOptions, host, link;
/*---SMTP OVER---*/
/*--Routing Started--*/
app.get('/', function(req , res) {
res.sendfile('index.html');
});
app.get('/send', function(req , res) {
rand=Math.floor((Math.random() * 100) + 54);
host= req.get(host);
link="http://"+req.get('host')+"/verify?id="+rand;
mailOptions={
to : req.query.to,
subject : "Please confirm your Email account",
html : "Hello,<br> Please Click on the link to verify your email.<br>Click here to verify"
}
console.log(mailOptions);
smtpTransport.sendMail(mailOptions, function(error, response){
if(error){
console.log(error);
res.end("error");
}else{
console.log("Message sent: " + response.message);
res.end("sent");
}
});
});
app.get('/verify',function(req,res){
console.log(req.protocol+":/"+req.get('host'));
if((req.protocol+"://"+req.get('host'))==("http://"+host))
{
console.log("Domain is matched. Information is from Authentic email");
if(req.query.id==rand)
{
console.log("email is verified");
res.end("<h1>Email "+mailOptions.to+" is been Successfully verified");
}
else
{
console.log("email is not verified");
res.end("<h1>Bad Request</h1>");
}
}
else
{
res.end("<h1>Request is from unknown source");
}
});
/*--------------------Routing Over----------------------------*/
app.listen(9999,function(){
console.log("Express Started on Port 3000");
});
Any help will be appreciated Thanks

You should be able to use nodemailer in sails pretty much the same, just change the app.gets into corresponding controller actions.
MailController.js:
module.exports = {
sendVerificationMail: function(req, res) {
// your app.get('/send') code
},
verifyEmail: function(req, res) {
// your app.get('/verify') code
}
}
As a side note, your verifying logic kinda breaks when another user tries to register before the first one has completed his registration:
First user requests for email verification, rand = 34 for example
Second user requests for email verification, rand = 58
First user tries to verify his email with id=34, verification fails since 34 !== 58
