        class="action-link"
        href.package = 'My.Package'

### Get cache lifetime of nodes

Source: https://neos.readthedocs.io/en/8.3/References/FlowQueryOperationReference.html

Gets the minimum of all allowed cache lifetimes for the nodes in the current FlowQuery context. To include already hidden nodes, invisible nodes must also be included in the context.

```javascript
q(node).context({'invisibleContentShown': true}).children().cacheLifetime()
```

--------------------------------

### Flow Standard File Header

Source: https://neos.readthedocs.io/en/8.3/References/CodingGuideLines/PHP.html

Every PHP file must start with a namespace declaration and a copyright header. Ensure the header includes the correct package and license information. Do not use '/**' to start the copyright header.

```PHP
<?php
namespace YourCompany\Package\Something\New;

/*
 * This file is part of the YourCompany.Package package.
 *
 * (c) YourCompany
 *
 * This package is Open Source Software. For the full copyright and license
 * information, please view the LICENSE file which was distributed with this
 * source code.
 */

```

### List Available Commands

Source: https://neos.readthedocs.io/en/8.3/Operations/CommandLine.html

Lists all available commands in the Neos CLI. Use this to get a general overview of the tools.

```bash
./flow help                     # lists all available command
./flow help <packageKey>        # lists commands provided in package
./flow help <commandIdentifier> # show help for specific command

```

### Example Nodetype for Asset Subtypes

Source: https://neos.readthedocs.io/en/8.3/Appendixes/ChangeLogs/8313.html

This example nodetype demonstrates how to configure properties for different asset subtypes (Video, Document, Audio) using the AssetEditor in the Neos backend. It shows how to define types, labels, and inspector groups.

```yaml
‘Neos.Demo:Content.Test’:
    superTypes:
        ‘Neos.Neos:Content’: true
        ‘Neos.Demo:Constraint.Content.Column’: true
        ‘Neos.Demo:Constraint.Content.Main’: true 
    ui:
        label: Test
        icon: picture
        position: start
    inspector:
        groups:
            settings:
                label: Test Settings 
    properties:
        video:
            type: Neos\Media\Domain\Model\Video
            ui:
                label: ‘Video’
                reloadIfChanged: true
                showInCreationDialog: true
                inspector:
                    group: ‘settings’
                    editor: Neos.Neos/Inspector/Editors/AssetEditor 
        document:
            type: Neos\Media\Domain\Model\Document
            ui:
                label: Document
                inspector:
                    group: ‘settings’
                    editor: Neos.Neos/Inspector/Editors/AssetEditor 
        audio:
            type: Neos\Media\Domain\Model\Audio
            ui:
                label: Audio
                inspector:
                    group: ‘settings’
                    editor: Neos.Neos/Inspector/Editors/AssetEditor
```

### Array.length

Source: https://neos.readthedocs.io/en/8.3/References/EelHelpersReference.html

Gets the number of elements in an array.

```APIDOC
## Array.length(array)

### Description
Get the length of an array

### Parameters
#### Path Parameters
- **array** (iterable) - Required - The array

### Return
(int)
```

--------------------------------

### Include Resources for All Backend Modules

Source: https://neos.readthedocs.io/en/8.3/Appendixes/ReleaseNotes/830.html

Configuration to add stylesheets and JavaScript to all backend modules simultaneously. This avoids the need to add resources to each module individually.

```yaml
Neos:
    moduleConfiguration:
        additionalResources:
            styleSheets:
                ‘My.Package’: ‘resource://My.Package/Public/JavaScript/Main.css’
            javaScripts:
                ‘My.Package’: ‘resource://My.Package/Public/JavaScript/Main.js’
```

--------------------------------

### Accessing Assets in Fusion

Source: https://neos.readthedocs.io/en/8.3/Appendixes/ChangeLogs/830.html

Provides examples of how to access Neos.Media assets using Fusion helpers. Ensure assets are tagged or in collections for effective searching.

```fusion
assetsByTag = ${Neos.Media.Assets.findByTag('MyTag')}
assetsByCollection = ${Neos.Media.Assets.findByCollection('MyCollection')}
assetsBySearchTerm = ${Neos.Media.Assets.findBySearchTerm('alice')}
```

--------------------------------

### Commit Message Format Example

Source: https://neos.readthedocs.io/en/8.3/_sources/References/CodingGuideLines/PHP.rst.txt

Demonstrates the standard format for commit messages, including type, summary, detailed explanation, and issue tracking.

```text
TASK: Short (50 chars or less) summary of changes

 More detailed explanatory text, if necessary.  Wrap it to about 72
 characters or so.  In some contexts, the first line is treated as the
 subject of an email and the rest of the text as the body.  The blank
 line separating the summary from the body is critical (unless you omit
 the body entirely); tools like rebase can get confused if you run the
 two together.

 Write your commit message in the present tense: "Fix bug" and not "Fixed
 bug."  This convention matches up with commit messages generated by
 commands like git merge and git revert.

 Code snippets::

  should be written in
  ReStructuredText compatible
  format for better highlighting

 Further paragraphs come after blank lines.

 * Bullet points are okay, too
 * An asterisk is used for the bullet, it can be preceded by a single
   space. This format is rendered correctly by Forge (redmine)
 * Use a hanging indent

 Fixes #123
