How to use a new FIHR server? about growth-chart-app HOT 10 OPEN

Yes, it should be possible. The simplest way would be to:

1. Host the PGC app somewhere. For example npm start will start small http server and then the app will be available at http://127.0.0.1:9000/
2. In the launch.html file at https://github.com/smart-on-fhir/growth-chart-app/blob/master/launch.html#L10-L11 add a patientId option. The value should be the ID of the patient (on your FHIR server) that you want to launch with.
3. Then load your launch.html file and pass a fhirServiceUrl parameter like so: http://127.0.0.1:9000/launch.html?fhirServiceUrl=http://my.fhir.server

@vlad-ignatov hi that works fine as long as you testing hapi fhir servers but if your fhir server requires Oauth Porcess i can get a token and patient data using POSTMAN, my next step is that i want to plugin my FHIR Server to test Growth Chart App but for that i need to get access token first within your app.?

Hi @usmanbahadur,

That was just an example of how to work-around SMART/Oauth. If you have an Oauth server, then you can register a client there and use the client_id in the launch.html file and launch as usual.

hi @vlad-ignatov
so i have done the following this autheitcates the app against fhir server but how do we actually search a patient?

from growth-chart-app.

It is a responsibility of the server to offer you a patient selection UI if you have stated that you need it using the launch/patient scope. You can also bypass that by adding a patientId option to the authorize call in your launch.html, but that will "fix" your app to always use that patient.

hi @vlad-ignatov

i have tried by providing static patientId when launching as stand alone patient app, the error is patient not found.

from growth-chart-app.

Does that patient exist on the server you are launching against?

BTW, the scope looks weird. Try "patient/*.read launch/patient".

from growth-chart-app.

@vlad-ignatov the patient exist in server, Azure FHIR Server does not like "patientId : smart-77777703"
so i had to convert patient id
var launchContext = {patient: patientId};
var launchContextString = encodeURIComponent(btoa(JSON.stringify(launchContext)));

Hello, I'm trying to connect to our FHIR server as well. Did you finish using the growth chart app with your own FHIR server ? I could use any help or samples to get started in this. Please let me know.

@hexicalsystems Use the following in launch.html file of the project, you would need client_id, patientid etc from your fhir service provider, a redirect_uri is also very important this is where you will see the patient data pulled out of your fhir service.
BW
FHIR.oauth2.authorize({
"scope": "patient$*.read",
"iss": "https://name-of-your-fhir-server.com",
"patientId": "patient-id-that-exist-in-your-fhir-server",
"client_id": "id-given-by-your-server",
"redirect_url": "uri-where-you-want-to-redirect-this-app"
)}
