This repository contains a Firebase Cloud Function that can be deployed to your CardinalKit Firebase project to automatically convert documents written to your Cloud Firestore in Open mHealth format by the CardinalKit iOS application into HL7 FHIR R4 Observation Resources. Mapping is based on the Open mHealth to HL7 FHIR Implementation Guide.
Before using this function, you will need to have created a CardinalKit mobile app and connected it to a Firebase backend. If you haven't done this yet, please follow the instructions here first. Then you can return and add the cloud functions to your Firebase project by following the directions below.
Log in to your Firebase account from the command line:
firebase login
Clone this repository, then open it in the terminal and configure your firebase project for the Cloud Function:
cd CardinalKit-OMH-to-FHIR/firebase
firebase init
Then select "Functions" >> "Use Existing Project" >> "Select your Firebase project" >> Choose Javascript as the language.
Now, install dependencies:
npm install
Then, deploy the included functions:
firebase deploy --only functions
If the installation succeeded, you will see a new HealthFhir subcollection appear for each user in your Cloud Firestore that your app collects HealthKit data for which will contain all your OMH data converted to FHIR Observations.
