Content Models and Handlers
MediaWiki allows for page content types other than wikitext. It offers built-in support for JavaScript, CSS, JSON and plain text. Extensions can use MediaWiki's ContentHandler mechanism to add new content models for accepting different formats and controlling how they are rendered, stored and edited.

This page contains information about different content models and their implementations. It may be incomplete as any extension can add their own content model. Content model refers to the internal ID that represents that content type. The content format is the mime-type of ways the content can be represented (serialized) in.

Core content handlers

These are the content handlers which are included in MediaWiki. The "content handler" column pertains to a content handler class found in the MediaWiki core repository.

Content handler	Content model	Content format(s)	Usage
CssContentHandler	css	text/css	For pages that contain CSS, like MediaWiki:Common.css
JavaScriptContentHandler	javascript	text/javascript	For pages that contain JavaScript, like MediaWiki:Common.js
JsonContentHandler	json	application/json	A generic model that stores information in the JSON format. Many extension content handlers build on top of this.
TextContentHandler	text	text/plain	A generic model that displays plain text (no formatting). It is not intended to be used directly, but it can be.
WikitextContentHandler	wikitext	text/x-wiki	Wikitext! The default in most pages.
