React Markdown
react-markdown is a React renderer that converts markdown text into a virtual DOM to safely display formatted content. It functions as a markdown syntax parser and renderer that transforms markdown strings into structural elements, ensuring XSS-safe content delivery.
The project allows for the mapping of standard markdown elements to custom React components for specialized styling and behavior. It supports syntax extensions through a plugin system, enabling additional formatting features such as tables, footnotes, and tasklists.
The system includes security primitives for HTML and URL sanitization, using element filtering and schema-based validation to remove unsafe tags. It also supports asynchronous plugin processing for data fetching during the transformation process.
Features
- Virtual DOM Rendering Engines - Converts markdown text directly into a virtual DOM tree to ensure XSS-safe content delivery in React.
- Markdown-to-HTML Transpilers - Parses markdown source into a virtual DOM model for safe web rendering and XSS prevention.
- Markdown Parsers - Processes markdown strings into structural elements using an extensible plugin system.
- Markdown Renderers - Transforms markdown syntax into safe React component layouts for displaying documentation.
- Schema-Based Tag Filters - Filters the output tree against a permitted list of tags to prevent the rendering of unsafe elements.
- Cross-Site Scripting Prevention - Implements schema-based filtering and sanitization to prevent cross-site scripting attacks during markdown rendering.
- Rendered Content Sanitization - Prevents cross-site scripting attacks by sanitizing rendered markdown and filtering unsafe HTML elements.
- React Component Tree Mappings - Transforms markdown abstract syntax trees directly into React component hierarchies for rendering.
- Component Mappings - Maps specific markdown node types to custom React component implementations for specialized rendering.
- Safe Rich Text Renderers - Implements a security-first rendering system that strips dangerous elements from user-generated markdown.
- Markdown Renderers - A React-based renderer that converts markdown text into a virtual DOM for safe display.
- Markdown Element Overrides - Allows replacing standard markdown HTML output with custom React components for specialized styling.
- Component Mapping Engines - Resolves markdown document elements to custom React components at runtime for interactive behavior.
- HTML Element Filters - Provides the ability to define permitted output tags and strip unsafe HTML elements from the rendered output.
- Plugin-Based Syntax Extensions - Allows external plugins to define new tokens and custom text transformations during the parsing phase.
- Asynchronous Processing Pipelines - Supports asynchronous plugin execution for data fetching during the markdown transformation process.
- URL Protocol Sanitizers - Transforms links to ensure they use permitted protocols and prevent malicious redirects.
- Plugin Execution Engines - Provides an execution pipeline that supports asynchronous plugin logic during the markdown rendering process.
- Asynchronous Rendering Hooks - Executes asynchronous plugins during rendering via server-side awaits or client-side hooks.
- Markdown - Supports third-party plugins that add specialized markdown syntax such as tables and footnotes.
- Markdown and Text - Renders markdown content as React components.
