Post Resource
A prior reading of how to use the SMART Client is required to understand this section.
Document Reference
Example: Post a DocumentReference to Epic
The following code snippet takes a Client object and uses it to post a DocumentReference note to Epic
Post new DocumentReference to Epic SMARTerFHIR client
const response = await client.create(myDocumentReference).catch((reason) => {
throw new Error(`Failed to create resource because: ${reason}`);
});
console.log(response);
The corresponding myDocumentReference:
The original myDocumentreference object
import { DocumentReference } from "fhir/r4";
const noteText = "Some example Note text"
const myDocumentReference: DocumentReference = {
"resourceType": "DocumentReference",
"status": "current",
"docStatus": "final",
"type": {
"coding": [
{
"system": "http://loinc.org",
"code": "11488-4",
"display": "Consultation Note"
}
],
"text": "Consultation Note"
},
"content": [
{
"attachment": {
"contentType": "text/plain",
"data": `${Buffer.from(noteText).toString('base64')}`
}
}
]
};
Note that we're posting the Document as an HL7 FHIR Resource defined using HL7's respective Typescript package
Additionally, our DocumentReference is missing Patient and Encounter information. That's because our create function for posting Resources automatically gets the Patient and Encounter context from our Client object and inserts it into myDocumentReference before posting it to the EMR. The respective response object shows us the Resource that was fully fleshed out and created as a result of calling the function:

Note that the content is stored in an attachment url.
The following is an example of how to read back the DocumentReference Binary content from the EMR to confirm that the POST was successful:
Retrieve Attachment Objects from Response
const docReferenceBinaryIds = response.content.map(item => item.attachment.url)
const attachments = docReferenceBinaryIds.filter((id): id is string => !!id).map(async id => {
return await client.requestResource(id)
})
attachments.forEach(async attachment => console.log(await attachment))
Patient
Example: Posting a Patient
The following code snippet takes a Client object and uses it to post a Patient resource to Epic:
Post new Patient to Epic SMARTerFHIR client
const response = await client.create(myPatient).catch((reason) => {
throw new Error(`Failed to create resource because: ${reason}`);
});
console.log(response);
Note that unlike the DocumentReference example, we do not provide a patient or encounter ID to the create function
The corresponding myPatient:
The original Patient object
const noteText = "Some example Note text"
const myPatient: Patient = {
"resourceType": "Patient",
"name": [
{
"use": "usual",
"given": [
"Demo"
],
"family": "Patient",

"Mr."
]
