Usage

Standalone NodeType

You can use the standalone Markdown NodeType on your pages to render Markdown. Per default the NodeType comes with the options to enable or disable the extensions for it. The Fusion component can be overwritten in your site package. For example, you can include some CSS class names in the HTML output.

Add the Markdown editor to custom NodeTypes

The package comes with two Mixins:

• Editor Mixin
• Options Mixin

Add the Mixins to your NodeType:

'Vendor.Site:Content.CustomNodeType':
    superTypes:
        'Neos.Neos:Content': true
        'Beromir.Markdown:Mixin.MarkdownEditor': true
        'Beromir.Markdown:Mixin.MarkdownSettings': true

The Settings Mixin is optional. It allows you to enable or disable the CommonMark extensions for the NodeType. If you do not use the Mixin, the global settings are used.

You have two options to render the Markdown in your Fusion component.

Fusion object:

renderer = afx`
<div>
    <Beromir.Markdown:Markdown/>
</div>
`

Eel helper:

html = ${Beromir.Markdown.Markdown.convertMarkdown(props.markdown)}
