This package implements ValidEmail using Match.Where. This means that you can use:

check(email, ValidEmail);

and:

if (Match.test(email, ValidEmail)) {
    // ...
}

For code clarity it also provides IsValidEmail:

if (IsValidEmail(email)) {
    // ...
}

By default, a very basic regexp is used:

ValidEmail.regex = /^[A-Z0-9\._%+-]+@[A-Z0-9\.-]+\.[A-Z]{2,}$/i;

But you can change the value of ValidEmail.regex to suit your needs.

Some extra regexps are provided:

// /^[^@]+@[^@]+$/;
ValidEmail.regex = ValidEmail.permissive;

And if you wanted to follow the rfc you could do this:

// from http://badsyntax.co/post/javascript-email-validation-rfc822
ValidEmail.regex = /^([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x22([^\x0d\x22\x5c\x80-\xff]|\x5c[\x00-\x7f])*\x22)(\x2e([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x22([^\x0d\x22\x5c\x80-\xff]|\x5c[\x00-\x7f])*\x22))*\x40([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x5b([^\x0d\x5b-\x5d\x80-\xff]|\x5c[\x00-\x7f])*\x5d)(\x2e([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x5b([^\x0d\x5b-\x5d\x80-\xff]|\x5c[\x00-\x7f])*\x5d))*$/;
