README

This package provides a more performant replacement for the asset usage calculation in Neos CMS 5.x, 7.x and 8.x.

In Neos >= 9.0, highly performant asset usage is included in the core, you do NOT need this package anymore then.

Upgrading to Neos 9

• remove the dependency to flowpack/neos-asset-usage
• there is no step 2 - that's it 🙂

Neos always calculated the asset usage when the information was requested. This could take quite long depending on the number of nodes and assets in a project.

This package solves the problem by using the registration service of Flowpack.EntityUsage to register a usage if an asset is referenced and unregister when the asset is not referenced by a node anymore. The data is stored in a database table and can be efficiently queried and accessed by the provided service.

Additionally, the package provides a replacement for the AssetUsageInNodePropertiesStrategy of Neos CMS. The core strategy is disabled via AOP.

TLDR

Viewing asset usages in Neos CMS will be super fast when this package is installed.

Using it with Flowpack.Media.Ui will also allow enabling additional features like filtering for unused assets and delete button are disabled if an asset is used.

Compatibility

Neos 5.2, Neos 7.x + Neos 8.x

Installation

Add the package, and the storage as dependency in your site package:

composer require --no-update flowpack/neos-asset-usage flowpack/entity-usage-databasestorage

The run composer update in your project root.

Finally you need to run the command to build the initial usage index:

./flow assetusage:update

This will store all usages in your database. If you deploy your project on another system you have to make sure that you run this command there.

It is recommended to run the command from time to make sure that no usages are in the database that don't exist anymore or usages are missing. When that happens, it is important that you try to find out where they come from. If you think this happened due to an error in this package, please open an issue with as much information as you can give.

Feature: Exclude node types from usage count

Possible use case: If you are using this package in combination with neos/metadata-contentrepositoryadapter, the metadata entries will be recognized as usage count. You can adjust this behaviour with the following settings.

Example to exclude all metadata node types from usage count:

Flowpack:
  Neos:
    AssetUsage:
      excludedNodeTypes:
        - 'Neos.MetaData:AbstractMetaData'

Example to exclude multiple custom metadata node types:

Flowpack:
  Neos:
    AssetUsage:
      excludedNodeTypes:
        - 'Vendor.PackageName:Custom.MetaData.NodeType1'
        - 'Vendor.PackageName:Custom.MetaData.NodeType2'

• Flowpack.EntityUsage.DatabaseStorage for storing usages in the database

Development goal

This functionality will at some point be integrated into the core of a future Neos CMS version.
