To create a client side of validation, you need to find a regular expression on which Laravel validates email .

In which file is the use of regular expressions?

    Why check email on a regular schedule if there is a good filter_var function?

    Laravel of the same opinion, and they do not use the regular season:

    /** * Validate that an attribute is a valid e-mail address. * * @param string $attribute * @param mixed $value * @return bool */ public function validateEmail($attribute, $value) { return filter_var($value, FILTER_VALIDATE_EMAIL) !== false; }
