rsc-markdown

Markdown for server components

---

rsc-markdown, a powerful markdown rendering library that supports React Server Components, powered by showdown and html-react-parser. We provide a powerful server component for rendering markdown content. Compatible with react, nextjs, and remix.

Next.JS Codesandbox Demo

Note: If you are using rsc-markdown with tailwindcss, it is recommended to also use @tailwindcss/plugin-typography because by default tailwind strips all styles off of native html elements, making the markdown content look very plain and like it is just pure text.

Features

• 🚀 Server-Side Rendering: Built for React Server Components, ensuring lightning-fast performance by rendering markdown content directly on the server.
• 🔒 Safe Rendering: Converts markdown to jsx without converting using dangerouslySetInnerHtml & sanitizes html with xss.
• 📝 Remark and Rehype Powered: Utilizes the powerful and flexible parsing and transformation capabilities of remark and rehype.
• 🎨 Custom Components: Allows for the substitution of standard markdown elements with custom React components.
• 🔧 Configurable Options: Supports options like trimming white space, GitHub Flavored Markdown (GFM), and syntax highlighting for code blocks.
• 🌈 Syntax Highlighting: Integrated with rehype-prism-plus for beautiful syntax highlighting in code blocks.
• 📈 Rendering Support: rsc-markdown is optimized for use with SSG (Static Site Generation), SSR (Server Side Rendering), and CSR (Client Side Rendering).
