Prgfx.Neos.AxeCore

This package integrates the axe-core accessibility analysis tools from Deque into the Neos inspector to allow editors to quickly determine accessibility issues on a document.

composer require prgfx/neos-axecore

The development of this package is supported by mindscreen GmbH.

Features

• Run axe-core analyzer for the current document and display accessibility errors in the inspector
• Highlight affected DOM nodes and select content-elements if available
• Pop-out results as separate window to keep errors open while fixing them
• Localized results based on user-preferences and translations provided by the axe-core project
• Export results for developers/integrators

Configuration

axe.run Options

You can specify the options passed to axe.run through the settings:

Neos:
  Neos:
    Ui:
      frontendConfiguration:
        Prgfx.Neos.AxeCore:runOptions:
          runOnly:
            type: 'rule'
            values: ['ruleId1', 'ruleId2', 'ruleId3']

Override used resources

If you want to use a specific (compatible) version of the axe-core library, you can override

Prgfx:
  Neos:
    AxeCore:
      script: 'resource://My.Package/Public/Path/To/axe.js'
      translations: 'resource://My.Package/Private/Path/To/locales/{language}.json'

By specifying a json without the {language} placeholder you could disable localization of the results.
