Assets app

Magnolia Assets app is a container app for asset management subapps such as Magnolia Assets subapp, Amazon S3 Assets or Bynder.

Unlike the older Assets app - 5 UI (artifactID magnolia‑dam‑app-compatibility), which is based on the UI framework used in Magnolia 5.7 (referred to as Magnolia 5 UI), the Assets app (artifactID magnolia-dam-app) is based on the Magnolia 6 UI framework.


The Assets app is installed by the Digital Asset Management module as its submodule and is bundled with the following Magnolia-built webapps:

  • magnolia-community-webapp

  • magnolia-community-demo-webapp

  • magnolia-dx-core-webapp

  • magnolia-dx-core-demo-webapp

If you want to use the app in your custom webapp, make sure that you also add an asset management subapp, for example the Magnolia Assets subapp (artifactID magnolia-dam-app-jcr).

By default, the Assets app container does not have any subapp defined and will not start without a subapp.


The app’s configuration is stored in /dam-app-core/apps/dam.yaml. The configuration can be modified for example by definition decoration, as is the case of the Magnolia Assets subapp, with a definition decoration available in /dam-app-jcr/decorations/dam-assets-app/apps/dam.subApps.yaml.

ZIP file checks

It is possible to protect against potential zip-bombs attacks by using the configuration properties shown in the table below, which are located here: /dam-app-jcr/dialogs/upload.yaml.

Current default values are 104857600 for zipEntrySizeLimit and 1000 for maxNumberCompressedFiles.

Example: ZIP file checks enabled in upload.yaml
      root: true
    zipEntrySizeLimit: 104857600
    maxNumberCompressedFiles: 1000
Property Description


Size limit for each compressed file in a ZIP (in bytes).


Maximum number of files included in a ZIP file.


To open the app, click the Assets tile in the App launcher:

Then, depending on what asset management subapps are installed, you can see the respective subapps as tabs in the Assets app. See below, for example, the Assets app with the Bynder Assets subapp and the Magnolia Assets subapp:
