 **isFQDN(str [, options])**             | check if the string is a fully qualified domain name (e.g. domain.com).<br/><br/>`options` is an object which defaults to `{ require_tld: true, allow_underscores: false, allow_trailing_dot: false, allow_numeric_tld: false, allow_wildcard: false, ignore_max_length: false }`.<br/><br/>`require_tld` - If set to false the validator will not check if the domain includes a TLD.<br/>`allow_underscores` - if set to true, the validator will allow underscores in the domain.<br/>`allow_trailing_dot` - if set to true, the validator will allow the domain to end with a `.` character.<br/>`allow_numeric_tld` - if set to true, the validator will allow the TLD of the domain to be made up solely of numbers.<br />`allow_wildcard` - if set to true, the validator will allow domains starting with `*.` (e.g. `*.example.com` or `*.shop.example.com`).<br/>`ignore_max_length` - if set to true, the validator will not check for the standard max length of a domain.<br/>
 **isFreightContainerID(str)**                      | alias for `isISO6346`, check if the string is a valid [ISO 6346](https://en.wikipedia.org/wiki/ISO_6346) shipping container identification.
 **isFullWidth(str)**                    | check if the string contains any full-width chars.
+**isValidGraphQLQuery(str [, options])** | check if the string is valid graphql query (note: uses parse function from graphql package).<br/><br/>`options` is an object which defaults to `{ allow_primitives: false }`. If `allow_primitives` is true, the primitives 'true', 'false' and 'null' are accepted as valid graphql query values.
 **isHalfWidth(str)**                    | check if the string contains any half-width chars.
 **isHash(str, algorithm)**              | check if the string is a hash of type algorithm.<br/><br/>Algorithm is one of `['crc32', 'crc32b', 'md4', 'md5', 'ripemd128', 'ripemd160', 'sha1', 'sha256', 'sha384', 'sha512', 'tiger128', 'tiger160', 'tiger192']`.
