Build Status NuGet

A PoC .NET source generator for mapping model classes to HL7 FHIR® Parameters resources.

Useful when interacting with FHIR® server operation endpoints.

Getting Started

dotnet add package FhirParametersGenerator

This sample code...

using FhirParametersGenerator;
using Hl7.Fhir.Model;
using Hl7.Fhir.Serialization;

var t = new TestModel
    Age = 123,
    Name = "Test",
    Code = new("http://snomed.info/sct", "386661006", "Fever"),

// the ToFhirParameters() extension method is code-generated
var parameters = t.ToFhirParameters();

Console.WriteLine(parameters.ToJson(new() { Pretty = true }));

// apply this attribute to the desired model class
public class TestModel
    public string Name { get; init; } = string.Empty;
    public int Age { get; init; } = 0;
    public CodeableConcept? Code { get; init; }

...will output:

  "resourceType": "Parameters",
  "parameter": [
      "name": "name",
      "valueString": "Test"
      "name": "age",
      "valueDecimal": 123
      "name": "code",
      "valueCodeableConcept": {
        "coding": [
            "system": "http://snomed.info/sct",
            "code": "386661006"
        "text": "Fever"


This library is in a very early stage and many edge and not-so-edge cases that are not covered by the generated source. The list of open issues is a good starting point to see what isn't yet supported. Contributions are of course always welcome.


A benchmark project exists which measures the performance of generating the source code for a 1000-property class: https://github.com/chgl/FhirParametersGenerator/blob/master/src/FhirParametersGenerator.Benchmark/Program.cs.

Benchmarking results over time are available at https://chgl.github.io/FhirParametersGenerator/dev/bench/.
