Getting started
Before I start explaining how you create a FHIR web service, you need to know about the structure in FhirStarter.
| Name of the library | Explaination |
|---|---|
| FhirStarter.Bonfire.STU3 | The Bonfire project is the main library. It is the core library which 99% of the logic lies in. |
| FhirStarter.Flare.STU3 | The Flare project contains only the global.asax and global.asax.cs file plus a xslt to render results to html. |
| Spark.Engine | The Spark.Engine code was originally in FhirStarter.Bonfire, but is now a separated library. |
| FhirStarter.Inferno | The Inferno project runs the FHIR service. This service references the Bonfire and Flare project directly for debugging purposes |
| Fhirstarter.Inferno.Template | The Inferno.Template project references the nuget packages from nuget.org, and can be used as a starting project for new FHIR projects since all the basic necessities are present in the template project. |
A FhirStarter service is based on the IFhirService interface. It contains all the necessary methods which the FhirController needs to access when receiving a request.
The FhirController is using ninject to create instances of IFhirServices, so you can have as many services as you want, but the resource in each service must be unique. So you can't for example have two Patient services in the same Inferno project.
Since most of the logic to handle FHIR is in the Bonfire project, the only thing needed to get things running is to copy the FhirStarter.Inferno.Template project and put it in your FHIR solution. This way you also ensure you get the updated nuget packages which are accessible through nuget.org
It is preferable to change the Inferno.Template project (assembly and all) to something more easily associative with what the service is supposed to do. For example, PatientRegistry if the Inferno service is just getting patients from a registry. If you change the assembly name, do also change the reference to the dll name in the appSetting element in the web.config (See the Settings for more information).
