Medplum TS/JS Library
npm install @medplum/coreThe Medplum JS Client Library is a pure TypeScript library for calling a FHIR server from the browser.
- FHIR validation and operations
- FHIR client to create, read, update, delete, patch, and search
- WebSockets for realtime communication
- Evaluation of FhirPath
- No external dependencies
Add as a dependency:
``bash`
npm install @medplum/core
Create a new MedplumClient:
`ts
import { MedplumClient } from '@medplum/core';
const medplum = new MedplumClient();
`
Create a MedplumClient with additional configuration options:
`ts
import { MedplumClient } from '@medplum/core';
const medplum = new MedplumClient({
baseUrl: 'https://www.example.com/fhir/R4/',
clientId: 'MY_CLIENT_ID',
});
`
`ts`
const medplum = new MedplumClient();
await medplum.startClientLogin(MY_CLIENT_ID, MY_CLIENT_SECRET);
If you are using Medplum as your FHIR server, you can use a direct sign-in API to authenticate email and password.
Before you begin
1. Create a project in the Medplum App
2. Enable Email/Password
After that, you can use the startLogin() method:
`ts`
const loginResult = await medplum.startLogin({ email, password, remember });
const profile = await medplum.processCode(loginResult.code);
console.log(profile);
Authenticate with a FHIR server via OAuth2 redirect:
`ts`
medplum.signInWithRedirect().then((user) => console.log(user));
Search for any resource using a FHIR search string:
`ts`
search
resourceType: K,
query?: URLSearchParams | string,
options: RequestInit = {}
): ReadablePromise
Example:
`ts`
const bundle = await medplum.search('Patient', 'given=eve');
bundle.entry.forEach((entry) => console.log(entry.resource));
`ts`
createResource
Example:
`ts`
medplum.createResource({
resourceType: 'Observation',
subject: {
reference: 'Patient/123',
},
valueQuantity: {
// ...
},
// ...
});
`ts`
readResource
Example:
`ts`
const patient = await medplum.readResource('Patient', '123');
`ts`
readHistory
Example:
`ts`
const historyBundle = await medplum.readHistory('Patient', '123');
`ts`
readVersion
Example:
`ts`
const version = await medplum.readVersion('Patient', '123', '456');
`ts`
updateResource
Example:
`ts`
const result = await medplum.updateResource({
resourceType: 'Patient',
id: '123',
name: [
{
family: 'Smith',
given: ['John'],
},
],
});
console.log(result.meta.versionId);
`ts`
deleteResource(resourceType: string, id: string): Promise
Example:
`ts`
await medplum.deleteResource('Patient', '123');
`ts`
patchResource
Example:
`ts`
const result = await medplum.patchResource('Patient', '123', [
{ op: 'replace', path: '/name/0/family', value: 'Smith' },
]);
console.log(result.meta.versionId);
`ts`
graphql(query: string, options?: RequestInit): Promise
Example:
`ts
const result = await graphql(
{
PatientList(name: "Alice") {
name {
given
family
}
}
});``
