FHIR UK Core NodeJS package

Hi,
Anyone has experience working with FHIR UK Core with node.js typescript?
We are looking for a library that can be used for validating FHIR resources against the UK Core profile. My research so far brought me to the validators in MedPlum client which perform validation via a FHIR server. However, Ideally, we want a library/package that can be standalone validating resources against UK profiles, offline without the need of a FHIR server.

Any advice would be appreciated.
