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
