Mobilizing Million Hearts

Mobilizing Million Hearts is a portable SMART On FHIR powered application to calculate and display the risk of having cardiac issues.

Getting Started

Configure your application

The application must be configured with the proper SMART on FHIR information in order to launch securely against your FHIR Server. Create a .env file in the app directory with your application configuration before building. The following variables are configurable.

NAME	REQUIRED	DEFAULT VALUE
CLIENT_ID	yes
SCOPE	yes
ISS	yes
REDIRECT_URI	yes
AUDITING	no	false
ENABLE_DEVELOPERS_LOG	no	false
BLOODPRESSURE_CUTOFF	no	5
CHOLESTEROL_CUTOFF	no	5

An example .env file might like this:

touch app/.env

CLIENT_ID=your-client-id
SCOPE=patient/Patient.read patient/Observation.read patient/MedicationOrder.read patient/MedicationStatement.read patient/MedicationAdministration.read patient/Condition.read patient/DocumentReference.read patient/DocumentReference.write
ISS=https://your-fhir-server/
REDIRECT_URI=http://where-your-app-is-deployed/

The server also offers some configuration to be more flexible in different situations. Create a .env file in the server directory.

touch `server/.env`

NAME	REQUIRED	DEFAULT VALUE
DB_STORAGE	no	../../data/database.sqlite3
NODE_ENV	no	development

How to Build and Run

This application is a modular Smart On FHIR application. The application that is sent to the client lives in the app directory. The Smart On FHIR launch server lives in the server directory.

You must create an application in a SMART on FHIR server such as Cerner Code.

1. Create an App

2. Select the following scopes at a minimum:

   - patient/Patient.read
   - patient/Observation.read
   - patient/MedicationStatement.read
   - patient/Condition.read
   

3. Use /launch.html as the launch context

4. Use / as the Redirect URI

5. See CONFIGURATION on how to build your application with your App details

6. Serve the app using the included Express server:

   cd server
   yarn install
   yarn migrate
   yarn start
   

7. Build the application

yarn install
yarn build

8. Launch the App from a SMART on FHIR portal

Because this app is a compiled React SPA, you must rebuild it on any change to the code. The server is configured to have its public path in the build location.

Or: Use docker-compose

docker-compose up

Or: Use docker

NODE_ENV=development docker build -t hearts .

docker run -p 3000:3000 hearts

SQLite

The application uses SQLite to persist some usage information when AUDITING is enabled. If you need access to this data, consider mounting a volume when running the application:

mkdir data
docker run -p 3000:3000 -v data:/usr/src/app/data hearts
