I using a util function in react /gui-development/src/util/isEmail.js
that checks a string with regex to validate is valid email or not
/**
* Check a string is a email or not
* @param {string} email
* @returns {boolean} is email
*/
export default function isEmail(email) {
/**
* Regex
*
** username group
* start with char_u
*
* OPTIONAL group
* - start with (.)
* - char_u group
*
** @
*
** domain group
* start with char_d
* (.)
* char_d
*
* OPTIONAL group
* - char_d
* - (.)
* - char_d
*/
// TODO : Solve error
let match = email
.trim()
.match(
/^(?'username'(?'char_u'[A-z0-9-#`!%$&+*/=?^-_{|}~]+)([.](?&char_u))?)@(?'domain'(?'char_d'[A-z-0-9-_]+)[.](?&char_d)([.](?&char_d))?)$/
);
return match !== null;
// return true;
}
But I got this error
ERROR in ./src/util/isEmail.js 33:34
Module parse failed: Invalid regular expression: /^(?'username'(?'char_u'[A-z0-9-#`!%$&+*/=?^-_{|}~]+)([.](?&char_u))?)@(?'domain'(?'char_d'[A-z-0-9-_]+)[.](?&char_d)([.](?&char_d))?)$/: Invalid group (33:34)
