# Inferno FHIRPath Service

The `inferno-framework/fhirpath-service` provides a persistent service for
evaluating [FHIRPath](http://hl7.org/fhir/R4/fhirpath.html).
This lightweight wrapper enables applications not implemented in Java, such as
the [Inferno Framework](https://inferno-framework.github.io), to interface with
the FHIRPath in a service environment. It is primarily being used within
the Inferno Framework to provide HL7® FHIR® validation services for tests.

Since this is just a lightweight wrapper around the FHIRPathEngine, most of
the functionality provided by this service is [implemented within the HL7® FHIR®
Core library](https://github.com/hapifhir/org.hl7.fhir.core), which is
developed and maintained independently of this project.

## Definitions

The base FHIR R4 definitions are loaded during setup. No other IGs or FHIR
versions are currently available.

## REST API

**[See here](rest-api.md) for the REST API documentation.**

## Installation

**System Requirements:** The FHIRPath Service requires Java 11 or above.

## Running Locally with Java

To build and run the test suite:

### *nix

```shell script
./gradlew build check test
```

### Windows

```shell script
gradlew.bat build check test
```

To run the app:

```shell script
./gradlew run
```

The port can also be set through the environment

```shell script
FHIRPATH_PORT=8080 ./gradlew run
```

## Running with Docker

Build

```shell script
./build_docker.sh
```

Run

```shell script
docker run -p 6789:6789 inferno_fhirpath_service
```

## Creating an Uber Jar

An uber jar can be created with:

```shell
./gradlew uberJar
```

By default, the uber jar will be located in `build/lib/`.

This uber jar can be executed with `java -jar InfernoFHIRPathService--uber.jar`
