This package provides some validators to be used in a Flow based project.

Included validators

  • Domain-Names
  • Geocodes (Latitude + Longitude pairs)


to be written...


This package's code is heavily inspired by code I wrote years ago for the Roketi Cluster Hosting Management application. Thanks to open-source, this code can now live on - while Roketi in the planned form will probably never come to fly.

Thanks to the inspiration from the phenaproxima/domain-constraint package, the domain name validator now also checks against the list of allowed top-level domains defined by IANA.

Thanks to my employer internezzo ag some parts of the packages could be done as paid working time + shared as open-source.
