FHIR OpenApi Generator

This is an (incomplete) node library that converts a FHIR CapabilityStatement into OpenAPI definitions. This is useful because once you have an OpenAPI file, you can use all the tooling avaialble for OpenAPI for your FHIR server.

Library usage

const FHIRClient = require('fhir-kit-client');
// const {generate} = require('fhir-open-api-generator`);

const client = new FHIRClient({baseUrl: 'http://hapi.fhir.org/baseR4'});

(async function() {
  const capabilityStatement = await client.capabilityStatement();
  console.log(JSON.stringify(capabilityStatement, null, 2))
  return generate(client.metadata); // result will be an OpenAPI definition
})().then(console.log).catch(console.error);

You would likely want to use this in combination with something like the swagger-ui-express package.

Command line usage

TBD

Limitations and assumptions

1. For now we render the capability statement for JSON only.
2. Currently only FHIR R4 is supported
