FHIR GraphQL Client

About the tool

The FHIR (Fast Healthcare Interoperability Resources) standard enables easy exchange of health information electronically. To enhance data querying and interactions, FHIR supports the usage of GraphQL.

GraphQL is a powerful open-source data query and manipulation language. It enhances the capabilities of FHIR by minimizing over-fetching of data and enabling complex querying.

I've built this FHIR GraphQL Client tool to allow users to efficiently author and send GraphQL queries to FHIR servers via a simple UI. Under the hood, the app executes the $graphql operation against the specified FHIR endpoint.
