Examples
Examples using promises...
const Client = require('fhir-kit-client');
const fhirClient = new Client({
baseUrl: 'https://sb-fhir-stu3.smarthealthit.org/smartstu3/open'
});
// Get SMART URLs for OAuth
fhirClient.smartAuthMetadata().then((response) => {
console.log(response);
});
// Direct request
fhirClient.request('Patient/123')
.then(respose => console.log(response));
fhirClient.request('Patient/123', { method: 'DELETE' })
.then(respose => console.log(response));
// Read a patient
fhirClient
.read({ resourceType: 'Patient', id: '2e27c71e-30c8-4ceb-8c1c-5641e066c0a4' })
.then((response) => {
console.log(response);
});
// Search for patients, and page through results
fhirClient
.search({ resourceType: 'Patient', searchParams: { _count: '3', gender: 'female' } })
.then((response) => {
console.log(response);
return response;
})
.then((response) => {
console.log(response);
return fhirClient.nextPage(response);
})
.then((response) => {
console.log(response);
return fhirClient.prevPage(response);
})
.catch((error) => {
console.error(error);
});
Examples using async/await...
const Client = require('fhir-kit-client');
const fhirClient = new Client({
baseUrl: 'https://sb-fhir-stu3.smarthealthit.org/smartstu3/open'
});
async function asyncExamples() {
// Get SMART URLs for OAuth
let response = await fhirClient.smartAuthMetadata();
console.log(response);
// Read a patient
response = await fhirClient
.read({ resourceType: 'Patient', id: '2e27c71e-30c8-4ceb-8c1c-5641e066c0a4' });
console.log(response);
// Search for a patient with name matching abbott, then paging
let searchResponse = await fhirClient
.search({ resourceType: 'Patient', searchParams: { name: 'abbott ' } })
console.log(searchResponse);
searchResponse = await fhirClient.nextPage(searchResponse);
console.log(searchResponse);
searchResponse = await fhirClient.prevPage(searchResponse);
console.log(searchResponse);
}
asyncExamples();

JSDoc-generated documentation with plenty of examples
Launch Examples (SMART, CDS Hooks)
To see how to follow launch and authorization workflows for FHIR applications, see the examples directory and examples README.
Example React App
FHIRKit Create React App provides a create-react-app template that can be used to create a sample React app using FHIRKit Client.
Even more Examples (client-side ones)
See https://github.com/Vermonster/fhir-kit-client-examples for examples in React, Angular, and React Native.
Logging
The debug library can provide logging
during development. Two different logging namespaces are provided, fhir-kit- client:info
logs each request and response, and fhir-kit-client:error
logs
errors. To enable logging during development, add one of the namespaces to the
DEBUG environment variable, or use fhir-kit-client:*
to enable both.
$ DEBUG=fhir-kit-client:* node smart-launch.js
