I want to validate all email inputs on my app with regex. But there is a problem, all the regex I have found allow emails with no TLD. I want a regex that can help me reject emails such as testing@testing,

Examples:

The current regex I use is : ^([a-zA-Z0-9_-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([a-zA-Z0-9-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})$

But it accepts testing@testing for example, and that is not what I want. How would I go about validating emails and rejecting ones without TLD

This is the regex which does what you want:

[A-Za-z0-9._%-]+@[A-Za-z0-9._%-]+\\.[a-z]{2,3}

I have tried this in my Angular app and it fails to match any emails
Please create a stackblitz as I think the problem is not with the regex.

Hi. I edited my earlier answer, now the regex will work.
