Run

npm run start This will start local version of expo with its own QR code to scan from Expo Go app.

Prepare Data

This app works with https://github.com/FHIR/Gravity-SDOH-Exchange-RI. With that web application you can create the correct data, of course, using a shared sandbox

To authenticate correctly your sandbox app should have proper redirectURI https://auth.expo.io/@khlukanets/Gravity-Patient-App-RI and scopes patient/*.* launch/patient offline_access

To generate correct linking url (the one that you click in your email) please refer to this as example: exp://exp.host/@khlukanets/Gravity-Patient-App-RI/--/import-server?title=Logica&fhirUri=https%253A%252F%252Fapi.logicahealth.org%252FGravitySandboxNew%252Fdata&clientId=e501d8e5-d742-462b-bf27-669e385ec243 where:

  • title is your server title (could be whatever)
  • fhirUri your secured fhir endpoint
  • clientId client id of your sandbox app

If you are running the app dev locally please refer to logicaParams variable in App.tsx and enter your title | fhirUri | clientId there. After app starts you will get console.log with correct linking. Or you can always enter those params manually from Create New Server screen and don't bother with linking process.
