Docker Quick Demo

  1. Clone the repository and run docker-compose up -d --build to bring up ClassExplorer to a docker container.
  2. Check localhost:52773/ClassExplorer/ in a little while - it should have the app already.

Full Installation from XML File

To install latest Caché Class Explorer, you just need to import ClassExplorer package. Download the archive from latest releases, and then import Cache/CacheClassExplorer-vX.X.X.xml file.

Web application

Note that importing ClassExplorer.WebAppInstaller class will also create a /ClassExplorer application. If you want to create WEB application manually, please, do not import this class. Anyway, importing this class requires %SYS permission.


Visit [server domain and port]/ClassExplorer/ (slash at end required) to enter application.


To build project, you need NodeJS platform to be installed. Then, clone source code and run npm install from the root of the project. This will install all necessary modules from NPM for the project.

After that and each next time just run npm run gulp command from the project root. This will generate build directory, where you will find XML file ready to import.

One can import/export the built source to the local Cache/URIS instance (see import.bat):


This will bring ClassExplorer-v*.*.*.xml to the build directory, which you can then package with npm run zip.


ZPM is the package manager for InterSystems products. Currently, the release pipeline for it is manual. The ZPM release should happen once the package is uploaded to InterSystems OpenExchange with the "ZPM" option checked in. This should grab manually moved files from build-for-zpm/ClassExplorer directory for the release.

Locally, one can run and test the application using Docker:

  1. Before each release, manually patch the version in the module.xml file.
  2. Run docker-compose up -d --build in the repository root to bring up ClassExplorer to a docker container.
  3. Check localhost:52773/ClassExplorer/ in a little while - it should have the app already.
  4. Run docker-compose exec iris iris session iris and then type zn "IRISAPP" zpm to start ZPM session in the "IRISAPP" namespace.
  5. Type load /irisdev/app to test whether ZPM can parse the repository root.
  6. Type classexplorer package to try to compile the package. It should say something like Module package generated: /tmp/dirymgtBA/classexplorer-1.20.0.tgz.
  7. Configure the test registry to publish the package repo -n registry -r -url -user test -pass test (type search to see the registries list).
  8. Finally publish the package classexplorer publish.
  9. Further steps to test it: https://
