Details on Installation

Overview

The ere-ps-app comprises two main components.

The ere-ps-app back-end which is a Java 11 Quarkus (https://quarkus.io/) application.
The ere-ps-app front-end UI, which is a browser based HTML, CSS and JavaScript application.

The repository for the front-end UI can be found here

Configuring the ERE-PS-App Front-End UI

Open a terminal window and do the following:

Clone the ere-ps-app back-end repository by running:

git clone https://github.com/ere-health/ere-ps-app.git
The repository of the front-end is setup as a submodule in the ere-ps-app repository. After cloning the ere-ps-app repository or to reference the latest version of the frontend repository, run the following command:

git submodule update --init
Cool tip! You can use one command which combines both of the previous commands to clone the ere-ps-app repository, and to update the front-end UI submodule as shown below:

git clone --recurse-submodules https://github.com/ere-health/ere-ps-app.git

The source files of the front-end UI will be located in the following directory location:

src/main/resources/META-INF/resources/frontend

At this point, you should now have access to the source files for both the backend and front-end of the application.

Updating the Front-End UI Submodule to Reference a Particular Branch in the Front-End UI Repo

Periodically, you may wish to update the front-end UI submodule to reference different branches in the front-end UI repository. You can do this by entering the following commands as shown below from the ere-ps-app directory:

Linux/MacOS
1. git submodule deinit --all
2. rm -rf .git/modules
3. git rm -rf src/main/resources/META-INF/resources/frontend
4. rm -rf src/main/resources/META-INF/resources/frontend
5. git submodule add -b < branch name > https://github.com/ere-health/front-end-ere.health.git src/main/resources/META-INF/resources/frontend

Running the ERE-PS-App Application

Software Requirements
1. Download and install the latest version of the OpenJDK 11 SDK. You can use your preferred package manager software on your computer to handle this, or simply download an archive or installer from a publishing site such as AdoptOpenJDK (https://adoptopenjdk.net/). Make sure to choose OpenJDK 11 (LTS) and the HotSpot version of the JVM.
2. Download and install the latest version of Apache Maven (https://maven.apache.org/).
3. The latest Chrome, Firefox or Edge Browser (https://www.google.com/intl/en/chrome, https://www.mozilla.org/en-US/firefox/new, https://www.microsoft.com/en-us/edge).

Running the Application (Development Mode)

Open a terminal window and change to the parent ere-ps-app directory of the back-end and then run the following commands:

In order to make sure you are working with the latest front-end UI, run the following first:

git submodule update --init

Then run:

mvn quarkus:dev

At this point, the application should be running as highlighted below.

You can access the front-end UI of the application by making reference to the following URL

http://localhost:8080/frontend/app/src/index.html

Verify Correct Reference to the Latest Front-End UI Version

To check that the ere-ps-app back-end is correctly referencing the front-end UI and its latest version, run the following command at a terminal window from the ere-ps-app parent directory:

git submodule status

You should see something similar to the following with the only difference being the preceding git revision number:

7887a70e4dbe35cede4d286dc57bc3bba608a48d src/main/resources/META-INF/resources/frontend (heads/main)

Environment Variables

List of Application Environment Variables

ERE_DIRECTORY_WATCHER_DIR

Specifies the path of the watch-folder for new muster 16 PDFs. Paths can be absolute or relative to the path location of the ere-ps-app.jar executable. For Windows environments, make sure to use the double backslash characters to represent Windows specific file separators (i.e. \).
ERE_CONNECTOR_TLS_CERT_TRUST_STORE_FILE

Specifies the path of the Titus Connector TLS certificate trust store. Paths can be absolute or relative to the path location of the ere-ps-app.jar executable. For Windows environments, make sure to use the double backslash characters to represent Windows specific file separators (i.e. \).
ERE_CONNECTOR_TLS_CERT_TRUST_STORE_PWD

Password for the Titus TLS certificate trust store. For Windows environments, make sure to use double quotes around numeric values that are to be interpreted as a string.
MUSTER16_TEMPLATE_CONFIGURATION

Allows for configuring which parsing profile the SVGExtractor module should use on startup of the application.

In the development dev profile, all environment variables have default values, provided through the application.properties file. Under other profiles, certain variable values are required to be explicitly provided as an environment variable. Namely, ERE_CONNECTOR_TLS_CERT_TRUST_STORE_FILE and ERE_CONNECTOR_TLS_CERT_TRUST_STORE_PWD.

The .env file should be located in the root project folder (ere-ps-app).

Important! Configure the .env file to be ignored and not checked into the source code repository.

In regard to file and directory paths, configure the values for the environment variables in the .env file to reference paths on your local computer.

An example of the layout of the contents in the .env file is shown below:

ERE_DIRECTORY_WATCHER_DIR=<YOUR_LOCAL_PATH>/watch-pdf
ERE_CONNECTOR_TLS_CERT_TRUST_STORE_FILE=<YOUR_LOCAL_PATH>/ere-ps-app/src/test/resources/certs/ps_erp_incentergy_01.p12
ERE_CONNECTOR_TLS_CERT_TRUST_STORE_PWD=<SECRET_VALUE_ON_YOUR_COMPUTER>
