Duplicate email or username validation using Async validator in Angular

[@opcapgaming2232]

As an Angular user, I valued this video on duplicate email validation, Sourav. But the verification process would be much smoother if you incorporated FilterBounce into it. It is honestly a game changer!

[@asifferdous2432]

this is for the client side, what about the backend validation? i still can register even if its showing duplicate email.... so how to do the back end validation?

[@souravkumarpaul]

It os always better to keep validation in backend also and you can do that in your store procedure or from backend api. But from UI you wont allow user to submit the for if duplicate email found. You may disable the submit button or onSubmit function always keep a check if the formName.valid is true only then allow to proceed.

Front-end validation is for user-friendliness. Back-end validation is to ensure data integrity (e.g avoid bad data in your application).

The input field still has the invalid class evenafter entering a unique email address
