Missing Rules

• active_url

  • This cannot be supported because JS does not support hostname lookups (dns_get_record in PHP)
  • This could be implemented if there was a reliable way to host a small API to do the lookup

• date_format

  • This can be added with something like return new Date(value).format(params[0]) === value;
  • Unfortunately that isn't so easy in vanilla js atm

• exists & unqiue

  • These are both rules relating to the database

• not_regex (to come)

• regex (to come)

  • Regex requires extra parsing to remove forward slashes around regex
