Medplum FHIR Type Definitions

This library contains TypeScript type definitions for all R4 types.

Installation

Add as a dependency:

npm install --save-dev @medplum/fhirtypes

Basic Usage

Consider the following untyped code:

const myPatient = {
  resourceType: 'Patient',
  name: 'George Washington',
};

Keen observers will note that Patient.name should not be a string. Instead, it should be an array of HumanName objects.

Let's add the type definition and see what happens:

import { Patient } from '@medplum/fhirtypes';

const myPatient: Patient = {
  resourceType: 'Patient',
  name: 'George Wasington',
};

Now "name" is a compile error. Developer tools with TypeScript support should provide feedback. For example, VS Code adds red squigglies and a helpful error message:

And now you will receive typeahead support:

Medplum fhirtypes typeahead

So we can build a well-formed example:

import { Patient } from '@medplum/fhirtypes';

const myPatient: Patient = {
  resourceType: 'Patient',
  name: [
    {
      given: ['George'],
      family: 'Washington',
    },
  ],
};
