Command Line Tool for HAPI FHIR
hapi-fhir-cli is the HAPI FHIR Command Line tool. It features a number of HAPI's built-in features as easy to use command line options.
Download and Installation
You can get the tool by downloading it from our GitHub Releases page (look for the archive named hapi-fhir-[version]-cli.tar.bz2 on OSX/Linux or hapi-fhir-[version]-cli.zip on Windows).
When you have downloaded the archive (either ZIP or tar.bz2), expand it into a directory where you will keep it, and add this directory to your path.
You can now try the tool out by executing the following command: hapi-fhir-cli
This command should show a help screen, as shown in the screeenshot below.
Download and Installation - Mac/OSX
hapi-fhir-cli is available as a Homebrew package for Mac. It can be installed using the following command:brew install hapi-fhir-cli
Note on Java version support: The HAPI library is designed to work in Java 6+, but the Command Line Tool required a minimum of Java 8. This is because the Jetty Web Server that is used within the tool has this requirement.
The tool should work correctly on any system that has Java 8 (or newer) installed. If it is not working correctly, first try the following command to test if Java is installed:
$ java -version
If this command does not produce output similar to the following, you should install/reinstall Java.
$ java -version java version "1.8.0_60" Java(TM) SE Runtime Environment (build 1.8.0_60-b27) Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
If this does not help, please post a question on our Google Group.
The CLI tool can be used to start a local, fully functional FHIR server which you can use for testing. To start this server, simply issue the command hapi-fhir-cli run-server as shown in the example below:
Note that by default this server will not be populated with any resources at all. You can easily populate it with the FHIR example resources by leaving it running and opening a second terminal window, then using the hapi-fhir-cli upload-examples command (see the section below).
The server uses a local Derby database instance for storage. You may want to execute this command in an empty directory, which you can clear if you want to reset the server.
Upload Example Resources (upload-examples)
The upload-examples command downloads the complete set of FHIR example resources from the HL7 website, and uploads them to a server of your choice. This can be useful to populate a server with test data.
To execute this command, uploading test resources to a local CLI server, issue the following: hapi-fhir-cli upload-examples -t http://localhost:8080/baseDstu2
Note that this command may take a surprisingly long time to complete because of the large number of examples.
The HAPI FHIR JPA server has a terminology server, and has the ability to be populated with "external" code systems. These code systems are systems that contain large numbers of codes, so the codes are not stored directly inside the resource body.
HAPI has methods for uploading several popular code systems into its tables using the distribution files produced by the respective code systems. This is done using the upload-terminology command. The following examples show how to do this for several popular code systems.
Note that the path and exact filename of the terminology files will likely need to be adjusted for your local disk structure.
