Orthanc Explorer 2

This Orthanc plugin implements a new user interface for Orthanc to replace the Orthanc Explorer.

Installation

Binaries are available:

• here on Github, you'll find the plugin for
  • Windows 64bits
  • Ubuntu 20.04
  • MacOS (Universal binary)
• in the Windows Installers (64bits version only), the plugin is enabled but, right now, the legacy Orthanc Explorer remains the default UI. Note that, in a future release, OE2 will become the default UI for Orthanc in the Windows Installers.
• in the orthancteam/orthanc Docker images, the plugin is enabled but, right now, the legacy Orthanc Explorer remains the default UI. Note that, in a future release, OE2 will become the default UI for Orthanc in the Windows Installers.

The binaries must be copied next to other Orthanc plugins (Windows: C:\\Program Files\\Orthanc Server\\Plugins, ubuntu: /usr/share/orthanc/plugins/). You should also possible make sure that the plugin is listed in the "Plugins" Orthanc configuration.

Configuration

Like any other Orthanc plugins, Orthanc Explorer 2 is configured through a json configuration file that is provided to Orthanc at startup.

At minimum, you should provide this configuration file:

{
    "Plugins": [ "." ],
    "OrthancExplorer2": {
        "Enable": true,
        "IsDefaultOrthancUI": false
    }
}

Using this minimal configuration file, Orthanc Explorer 2 is accessible at http://localhost:8042/ui/app/ . If IsDefaultOrthancUI is set to true, Orthanc Explorer 2 will replace the built-in Orthanc Explorer.

If you are using Docker, the easiest way to try the new Orthanc Explorer 2 is to run this command and then open a browser in http://localhost:8042/ui/app/ (login: orthanc, pwd: orthanc)

docker pull orthancteam/orthanc:latest
docker run -p 8042:8042 orthancteam/orthanc:latest

Front-end development

Prerequisites:

• install nodejs version 14 or higher and npm version 6 or higher
• install nginx

Then, to continuously build and serve the front-end code on your machine, in a shell, type:

cd WebApplication
npm install
npm run dev

Npm will then serve the /ui/app/ static code (HTML/JS).

Then, launch an Orthanc with the OE2 plugin already enabled and listening on localhost:8043. This can be achieved with by typing this command in another shell:

docker run -p 8043:8042 -e ORTHANC__AUTHENTICATION_ENABLED=false orthancteam/orthanc:24.6.2

This Orthanc will serve the /ui/api/ routes.

In third shell, type:

sudo ./scripts/start-nginx.sh

This will launch an nginx server that will implement reverse proxies to serve both the static code and the Orthanc Rest API on a single endpoind. You may then open http://localhost:9999/ui/app/ to view and debug your current front-end code. As soon as you modify a WebApplication source file, the UI shall reload automatically in the browser.

Edit scripts/nginx-dev.conf if needed.

Compilation

Prerequisites to build the frontend: you need nodejs version 14 or higher and npm version 6 or higher.

To build the frontend:

cd WebApplication
npm install
npm run build

And then, to build the C++ plugin:

cd /build
cmake -DWEBAPP_DIST_SOURCE=LOCAL -DALLOW_DOWNLOADS=ON -DCMAKE_BUILD_TYPE:STRING=Release -DUSE_SYSTEM_ORTHANC_SDK=OFF /sources/orthanc-explorer-2/
make -j 4

LSB (Linux Standard Base)

Here are the build instructions for LSB:

cd WebApplication
npm install
npm run build
cd ..
mkdir build-lsb
cd build-lsb
LSB_CC=gcc-4.8 LSB_CXX=g++-4.8 cmake -DCMAKE_TOOLCHAIN_FILE=../Resources/Orthanc/Toolchains/LinuxStandardBaseToolchain.cmake -DALLOW_DOWNLOADS=ON -DSTATIC_BUILD=ON -DUSE_LEGACY_JSONCPP=ON -DWEBAPP_DIST_SOURCE=WEB ..
make -j4

Pre-compiled LSB binaries can be found at: https://orthanc.uclouvain.be/downloads/linux-standard-base/orthanc-explorer-2/index.html

Linking against system-wide Orthanc Framework

Here are the build instructions to dynamic link against the system-wide Orthanc Framework:

cd WebApplication
npm install
npm run build
cd ..
mkdir build-system
cd build-system
cmake .. -DCMAKE_BUILD_TYPE=Debug -DORTHANC_FRAMEWORK_SOURCE=system -DUSE_SYSTEM_GOOGLE_TEST=OFF -DALLOW_DOWNLOADS=ON -DUSE_SYSTEM_ORTHANC_SDK=OFF -DWEBAPP_DIST_SOURCE=LOCAL
make -j4
