FHIR is a data exchange standard maintained by the Health Level Seven International (HL7), a standards body. FHIR seeks to be the next-generation foundation by which electronic health records (EHRs), digital health applications, and consumers use and exchange structured healthcare data. FHIR aims to supplant existing HL7 standards such as HL7 version 2 (HL7v2) and HL7 version 3 (HL7v3).

The following video will share the results of implementing FHIR as a  model for communication across a microservice based on React, Node with Express js, and a database in postgres.
