if you are just testing on your local machine, one simple way of understanding how to do it can be :

Assuming you already know sending mails through nodemailer..

Once user signs up, after storing sign-up data in your database, on your server side take user email from sign-up data received and a random generated number and build a custom url with the address of page where user will be directed after he/she clicks on the link given in mail.

var customUrl = "http://"+ your host + "/" + your verification web-page + "?email=" + userEmail + "&id=" + randomNumber;

An example can be:

var userEmail = someone@example.com
var host = localhost:8080
var directWebPage = verifyUserEmail.html
var randomNumber = // generate with math.random() // lets say 111

Putting in above format of customUrl it looks something like this

customUrl:http://localhost:8080/verifyUserEmail.htmlemail=someone@example.com&id=111

Save this customUrl somewhere (probably in your database) Now, send an email to user with email body containing this cutomUrl link.

Click to verify your email

When user clicks on the link he/she will be directed to verifyUserEmail.html page and when that happens you can extract the page url containing email and id information

For example in angular I go like this-

var urlVerifyData = $location.url(); or $location.absUrl();

Now extract email form urlVerifyData string using javascript string methods

Request your server with this email and urlVerifyData

Now query your database for this email and verify previously stored customUrl with user's urlVerifyData

If they match, hola ! You got yourself a genuine user !!!
