as @StefanGarofalo said, all it takes is for an attacker to inspect-element (your FORM), remove the required attribute and modify the type and just submit the form (either by click or JS). This answer makes no sense. UI is not backend validation, and it should never be treated as such.

@KNP Multiple @ is valid only if the extra "@" appear in username part and is wrapped in double quote. It seems that also the second point (missing extension) is not valid anymore since 2013 (icann.org/en/announcements/details/…), but yes it depends, I guess someone could consider extension optional. Finally, I choose the module address from joi: joi.dev/module/address/api/?v=4.1.0#emailisvalidemail-options to validate email addresss in my app.

At first I found this answer useful, but I tried with some invalid email address and the regex said there were valid... by example : bar@domain (extension is missing), A@b@[email protected] (multiple @) and so on (cf en.wikipedia.org/wiki/Email_address#Examples). I found a nice regex here: emailregex.com

Updating the regex as the spec on the source listed has changed.

this is good, but the problem with this is that it must be inside a form tag and submitted by a submit input, which not everyone has the luxury of doing. Also, you can't really style the error message.
