Class: MedplumClient

The MedplumClient class provides a client for the Medplum FHIR server.

The client can be used in the browser, in a Node.js application, or in a Medplum Bot.

The client provides helpful methods for common operations such as: 1) Authenticating 2) Creating resources 2) Reading resources 3) Updating resources 5) Deleting resources 6) Searching 7) Making GraphQL queries

Here is a quick example of how to use the client:

import { MedplumClient } from '@medplum/core';
const medplum = new MedplumClient();

Create a Patient:

const patient = await medplum.createResource({
resourceType: 'Patient',
name: [{
given: ['Alice'],
family: 'Smith'
}]
});

Read a Patient by ID:

const patient = await medplum.readResource('Patient', '123');
console.log(patient.name[0].given[0]);

Search for a Patient by name:

const bundle = await medplum.search('Patient', 'name=Alice');
console.log(bundle.total);
