Markdown rendering with react-markdown

Rich text content from Rails often comes as Markdown. The react-markdown library renders Markdown to React components with customizable styling and sanitization. I configure it to use syntax highlighting via react-syntax-highlighter for code blocks, customize heading levels for semantic HTML, and add target='_blank' to external links. The remarkGfm plugin enables GitHub-Flavored Markdown features like tables and task lists. For security, I use rehype-sanitize to prevent XSS attacks from user-generated content. Custom component mapping lets me render Markdown elements as styled components that match the design system. This approach gives users rich formatting while maintaining full control over rendered HTML.
