Inferno US Core R4 Reference Server

This is a FHIR reference implementation server supporting the US Core R4 IG and SMART Launches.

By default, you can browse the server at

http://localhost:8080/reference-server, and the FHIR endpoint is at http://localhost:8080/reference-server/r4

Running with Docker

The server runs using two containers, one for the server, and one for the database. You can build the containers with docker-compose build and run both containers with docker-compose up.

Note that sometimes on the initial start up, the database initialization might cause the inferno reference server container to not start correctly, so you may need to stop the container with docker-compose down and restart it with docker-compose up .

Resetting the server

You can delete the server's data by stopping the containers with docker-compose down and then running docker volume rm inferno-reference-server_fhir-pgdata to remove the existing volume. Note that the default data will be reloaded when starting the containers.

The database will be initially populated by the default initdb.sql script. To update the default initial data with the data in the current db container, run docker-compose exec db pg_dump -U postgres postgres > initdb.sql

Running without Docker

System Requirements: The reference server requires Java 11 or above.

If you cannot run docker, you will need to create a postgres database.

Once you have done that, update the src/main/resources/hapi.properties to connect datasource.url, datasource.username, datasource.password, datasource.schema (or make your existing postgres db have the provided values).

Once that is done, you can run an instance of the fhir-reference server using mvn jetty:run. You should be able to go to localhost:8080 to see information about the fhir server.

To populate the database with sample data, run bundle install then bundle exec ruby upload.rb Note: make sure the jetty server is running, and that the FHIR_SERVER variable at the top of upload.rb corresponds to your running fhir reference server.

Using with Apps

Currently, there is no registration process. To use with an app, use the default client ids:

To use as a public client, use SAMPLE_PUBLIC_CLIENT_ID as the client id.

To use as a confidential client, use SAMPLE_CONFIDENTIAL_CLIENT_ID as the client id, and SAMPLE_CONFIDENTIAL_CLIENT_SECRET as the client secret.

To launch an app from the EHR go to reference-server/app/app-launch

The Bulk Data Token Endpoint is /reference-server/oauth/bulk-token

The registered Bulk Data Client ID is eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6InJlZ2lzdHJhdGlvbi10b2tlbiJ9.eyJqd2tzX3VybCI6Imh0dHA6Ly8xMC4xNS4yNTIuNzMvaW5mZXJuby8ud2VsbC1rbm93bi9qd2tzLmpzb24iLCJhY2Nlc3NUb2tlbnNFeHBpcmVJbiI6MTUsImlhdCI6MTU5NzQxMzE5NX0.q4v4Msc74kN506KTZ0q_minyapJw0gwlT6M_uiL73S4.

init.db provides the following resources:

  • Patients with ids 85 and 355
  • Groups with ids 1a and 64fdf2a5-ebad-4ed0-a512-567970843d49. Both Groups contain patients 85 and 355 as members.

upload.rb includes the resources above, except the Group with id 1a.

Custom Authentication Token

If you would like to execute requests without going through the process to get a token, you can set the environment variable CUSTOM_BEARER_TOKEN to a value of your choice.

Revoking a token

To revoke a token, go to reference-server/oauth/token/revoke-token

The tokens are currently saved in memory, so if the reference server is restarted, all existing tokens will be invalid

Running Read-Write Mode

By default, the Dockerized server runs in read-only mode – meaning, operations modifying the state of the server are not supported. For example, requests to CREATE, UPDATE, or DELETE a resource will receive a 405 Method Not Allowed error. To adjust this while running Docker, change the READ_ONLY environment variable to false in ./docker-compose.yml. If running without Docker, run mvn jetty:run -DREAD_ONLY=false when starting the server.

Running Tests

Tests can be run with:

mvn test

Running Checkstyle

Checkstyle can be run with:

mvn checkstyle:check
