QueryTypes
Ƭ QueryTypes: URLSearchParams | string[][] | Record<string, any> | string | undefined
QueryTypes defines the different ways to specify FHIR search parameters.
Can be any valid input to the URLSearchParams() constructor.
TypeScript definitions for URLSearchParams do not match runtime behavior. The official spec only accepts string values. Web browsers and Node.js automatically coerce values to strings. See: https://github.com/microsoft/TypeScript/issues/32951

ResourceArray
Ƭ ResourceArray<T>: T[] & { bundle: Bundle<T> }
ResourceArray is an array of resources with a bundle property. The bundle property is a FHIR Bundle containing the search results. This is useful for retrieving bundle metadata such as total, offset, and next link.

|---|---|---|
resourceType | string | The candidate resource type string. |
Returns
boolean

validateResourceType
▸ validateResourceType(resourceType): void
Validates that the given string is a valid FHIR resource type. On success, silently returns void. On failure, throws an OperationOutcomeError.
validateResourceType('Patient'); // nothing
validateResourceType('XYZ'); // throws OperationOutcomeError
Note that this depends on globalSchema, which is populated by the StructureDefinition loader.
In a server context, you can load all schema definitions:
import { indexStructureDefinitionBundle } from '@medplum/core';
import { readJson } from '@medplum/definitions';
import { Bundle } from '@medplum/fhirtypes';
indexStructureDefinitionBundle(readJson('fhir/r4/profiles-resources.json') as Bundle);
In a client context, you can load the schema definitions using MedplumClient:
import { MedplumClient } from '@medplum/core';
const medplum = new MedplumClient();
await medplum.requestSchema('Patient');
Parameters
| Name | Type | Description |
|---|---|---|
resourceType | string | The candidate resource type string. |
Returns
