An npm-published set of TypeScript definitions for Fast Healthcare Interoperability Resources (FHIR).

Install this into an existing TypeScript project with:

npm install @automate-medical/fhir-schema-types

The definitions are exported in the root level of the module, by version. You can import the latest stable version by default. You can also import named versions.

import FHIR from '@automate-medical/fhir-schema-types'

import { R4 as FHIR } from '@automate-medical/fhir-schema-types'

You can also import specific versions.

import { v4_6_0 as FHIR } from '@automate-medical/fhir-schema-types'

This library exposes type and interface definitions in TypeScript for all of the elements and resources in FHIR. You can use it in your TypeScript projects to bring type-safety guarantees to your programs that manipulate FHIR documents. We wrote a custom JSON schema parser to achieve this, and to ensure maximum flexibility so that the project can be maintained into the future.

Note This project is semantically versioned. We make no commitments about the stability of our interfaces until 1.0.0.

• Simple translation of JSON Schema definitions to type and interface definitions
• Support for const values
• Support for using named enum types instead of union types that enumerate field options
• Support for class definitions instead of interfaces
• Public test suite/CICD
• Support for version 4.0.1 (R4) and latest published 4.6.0
• Programatically download JSON Schema definitions for every version of FHIR and export schema
• Support definitions for the Graphql definitions provided in 4.6.0+
• Define a contributor license agreement
• Publish NPM module
• NPM build should include a bundle + sourcemaps instead of the raw build

Building the project can be done with:

npm run build

At present, you must create a directory in the root of the project called hl7, inside of which you must create specific fhir.schema.json files for each of the versions you need to build. In the future, the project will download the assets itself.
