Introduction

What?

Graphir is an example lightweight proxy that reshapes GraphQL queries and mutations into standard FHIR REST requests.

This example uses the Azure implementation of FHIR as its backend.

Why?

The FHIR schema encompasses large objects that can be cumbersome to develop client applicatons with. By providing a Graph QL interface over a FHIR API, we hope to accelerate client app development agility.

Getting Started

Requirements

To follow this guide for running locally you will need the following

• dotnet 6.0
• Visual Studio 2022 (Professional or Enterprise)
• Prerequisites API app registration & client App Registration

Running Locally

• Open Solution with Visual Studio
• Right click on the Graphir.API poject and select "Manage User Secrets"
• Add your information from app registrations

{
	"AzureAd": {
    	"Instance": "https://login.microsoftonline.com/", // ???
    	"Domain": "hlshack.onmicrosoft.com", // ???
    	"TenantId": "<add the tenant id from the azure tenant containing your app registrations here>",
    	"ClientId": "<add the client id from your client app registration here>",
    	"ClientSecret": "<add the client secret from your client app registration here>"
  }
}

• Compile
• Run/debug local

Calling Graphir

With Postman

• Install Postman
• Add a new POST request
• Add the URI https://localhost:5001/GraphQL
• Add the body of your request in the "Body" tab e.g.

query patientList {
  PatientList {
    id
    name { given family }
    birthDate
  }
}

• Open up the Authorization tab
• For Type, select 'OAuth 2.0'
• In the Configure New Token section
  • select 'Authorization Code' for Grant Type (*if you have multi-factor enabled, select 'Authorization Code (with PKCE)')
  • Leave 'Authorize with browser' checked
  • Auth URL: https://login.microsoftonline.com/{{tenantId}}/oauth2/v2.0/authorize
  • Access Token URL: https://login.microsoftonline.com/{{tenantId}}/oauth2/v2.0/token
  • ClientId: <client id>
  • Scope: <insert scope from API app registration>
• Click 'Get New Access Token'

In Banana Cake Pop UI

• You will need to complete the section "With Postman" so that you can generate a valid access token.
