The SMART-on-FHIR team has built a node application to call Bulk Data $export and facilitate the calls to get a bearer token.

1. Clone the Bulk Data Client repository

/git/wffh/2023$ git clone -b main-pb --single-branch \
    https://github.com/prb112/bulk-data-client.git && \
    cd $(basename $_ .git)

Note I added a changes to support the IBM FHIR Server.

2. Install nvm

$ brew install nvm

3. Switch to Node 16

$ nvm use 16
Now using node v16.13.0 (npm v8.1.2)

4. Install Node 16

$ nvm install

5. Create the binaries

$ npm run clean && npm run build

> bulk-data-client@1.0.0 clean
> rm -rf ./built


> bulk-data-client@1.0.0 build
> tsc

5. Create the config/ibm-fhir-server.js – update the fhirUrl, tokenUrl and privateKey. I used the RS384 Key.

6. Run the application

$ AUTO_RETRY_TRANSIENT_ERRORS=1 SHOW_ERRORS=1 node . --config config/ibm-fhir-server.js  --_type=Patient
Kick-off started
Got new access token

    }
  ],

Do you want to signal the server that this export can be removed? [Y/n]n

If you need to debug, you’ll see all the outputs:

NODE_DEBUG=* AUTO_RETRY_TRANSIENT_ERRORS=1 SHOW_ERRORS=1 node . \
   --config config/ibm-fhir-server.js

7. The files are downloaded to a local directory, and you can check the data. cat downloads/1.Patient.ndjson

As you can see the bulk-data-client is a handy tool to test Bulk Data with $export with SMART Backend Services Authorization.

We opened a few issues with the bulk data client team:

1. Bearer token is expected to be capitalized Bearer. #1
2. User-Agent string is awkward #3
3. Output doesn’t give a lot of details on what resourceType was exported #5

And one we’re watching:

4. Provides token even if requiresAccessToken is false #2

We opened an Pull Request #1 to address 1,2,4.
