Question: How to use fhir-path-cli?

In IBM FHIR Server 4.7.0, the IBM FHIR Server team introduced fhir-path-cli and related to a blog on $everything.

Now, let’s download some sample data on the server using the Integration Test data.

1. Download the Sample Data

curl -L https://raw.githubusercontent.com/IBM/FHIR/main/fhir-server-test/src/test/resources/testdata/everything-operation/Antonia30_Acosta403.json -o Antonia30_Acosta403.json

2. Load the Sample Data bundle to the IBM FHIR Server

curl -k --location --request POST 'https://localhost:9443/fhir-server/api/v4' \
--header 'Content-Type: application/fhir+json' \
--header "Authorization: Basic ${DUMMY_PASSWORD}" \
--data-binary  "@Antonia30_Acosta403.json" -o response.json

3. Scan the response.json for any status that is not "status": "201". For example, the status is in the family of User Request Error or Server Side Error.

4. Check the response.json and find the id for Patient (it should be the first one).

        {
            "response": {
                "id": "178f4a3f869-6abfe1e6-3a4a-4c9a-81a8-fb8c6263e003",
                "status": "201",
                "location": "Patient/178f4a3f869-6abfe1e6-3a4a-4c9a-81a8-fb8c6263e003/_history/1",
                "etag": "W/\"1\"",
                "lastModified": "2021-04-21T13:34:50.207684Z"
            }
        },

5. Check the Patient/[id]/$everything with a _type constraint and _since.

• Request *

curl -k --location --request GET 'https://localhost:9443/fhir-server/api/v4/Patient/178f4a3f869-6abfe1e6-3a4a-4c9a-81a8-fb8c6263e003/$everything?_type=CarePlan,CareTeam&_since=2021-01-01T00:00:00Z&_count=1' \
    --header 'Content-Type: application/fhir+json' \
    --header "Authorization: Basic ${DUMMY_PASSWORD}" -o care.json

• Response *

{
    "resourceType": "Bundle",
    "id": "689856f9-6ef6-4d74-8f77-a813ff7b1c6d",
    "type": "searchset",
    "total": 11,
    "entry": [
        {
            "fullUrl": "https://localhost:9443/fhir-server/api/v4/Patient/178f4a3f869-6abfe1e6-3a4a-4c9a-81a8-fb8c6263e003",
            "resource": {
                "resourceType": "Patient",
                "id": "178f4a3f869-6abfe1e6-3a4a-4c9a-81a8-fb8c6263e003",
                "meta": {
                    "versionId": "1",
                    "lastUpdated": "2021-04-21T13:34:50.207684Z"
                }
                ...
            }
        }
    ]
}

You’ll see further down CareTeam and CarePlan resources…

7. This is where we can have a bit of fun… download the fhir-path-cli

curl -L https://github.com/IBM/FHIR/releases/download/4.7.0/fhir-path-4.7.0-cli.jar -o fhir-path-4.7.0-cli.jar

6. Let’s run the fhir-path-4.7.0-cli.jar and test a FHIRPath.

Command Line

java -jar fhir-path-4.7.0-cli.jar --path 'entry.fullUrl' --file care.json

You’ve seen a brief introduction to fhir-operation-everything and a bonus fhir-path-cli showing the output.

Note, DUMMY_PASSWORD should be replaced with or set as a value when the corresponding curl steps are executed.

Thanks to my colleague that implemented $everything.
