Article José Pereira · Jun 5, 2021 6m read SMART on FHIR JS Library and examples in iris-on-fhir Introduction In the first article, a simple tutorial helped you to set up your FHIRaaS deployment. Now, let's move forward and introduce a JS library to access the FHIR resource. In the end, two examples of usage of this library will be presented, exploring the Appointment FHIR resource type. SMART on FHIR JavaScript Library FHIR is a REST API, so you can use any HTTP client in order to use it. But, it’s always a good idea to have help. #InterSystems IRIS for Health #Open Exchange Open Exchange app 3 0 0 1.5K

There's no need for any configuration because the library uses the standard of defined by the resource type. So, I decided to apply the same idea, but for charts.
