clinical:example-plugin

This is an example plugin for Node on FHIR. It will provides an example reference of how to create:

an HTTP REST endpoint
a database collection
server side publication
client side subscription
a reactive user interface
custom settings files

When implemented, you will be able to post data to the REST endpoint, and see the user interface automatically update to reflect the changes.

Example: Body Mass Index - Data Pipeline

The BodyMassIndex calculator relies on SMART on FHIR to fetch FHIR Patient and FHIR Observation resources. We then create a FHIR RiskAssessment for obesity. When fetching from an upstream FHIR Server, the overall data architecture and sequence diagram looks like the following.
