Markdown

A simple Markdown widget for Flarum 2.0, built as a widget for fof/forum-widgets-core. Same skeleton as linkrobins/html-widget, with a Markdown renderer in front of the body.

What it does

Adds one configurable Markdown widget to the FoF Forum Widgets placement editor. Admin sets:

• Title — optional, shown above the body
• Icon — FontAwesome class (e.g. fab fa-markdown)
• Markdown body — standard GitHub-flavored Markdown, rendered to HTML on the client

Drag and place it from the FoF Forum Widgets admin page like any other widget.

Requirements

• Flarum 2.0 or later
• fof/forum-widgets-core installed and enabled

The Markdown renderer (marked) and the HTML sanitiser (DOMPurify) are bundled into the extension — nothing is fetched from a CDN at runtime.

Markdown features

Supports the full Markdown syntax that marked.js handles, including:

• Headings (# H1, ## H2, ...)
• Bold (**bold**) and italic (*italic*)
• Lists (ordered and unordered)
• Links and images
• Code spans and fenced code blocks
• Blockquotes
• Tables (GFM)
• Horizontal rules
• Inline HTML (sanitised before display)

The widget styles headings, lists, code, blockquotes, and tables to fit cleanly in any placement.

Security note

The rendered HTML is passed through DOMPurify before display, so <script> tags, event-handler attributes, and other unsafe markup in the Markdown body are stripped. The body is still admin-only — treat it like any other admin-controlled content.
