Markdown for react server components

---

rsc-markdown, a powerful markdown rendering library for React Server Components. This library uses remark and rehype to provide a powerful server component for rendering markdown content. Compatible with react, nextjs, and remix.

Features

• 🚀 Server-Side Rendering: Built as a React Server Component, ensuring lightning-fast performance by rendering markdown content directly on the server.
• 🔒 Safe Rendering: Does not use dangerouslySetInnerHTML, ensuring a secure rendering process.
• 📝 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.

Installation

To use rsc-markdown in your project, you can install it via npm or yarn:

npm install rsc-markdown

yarn add rsc-markdown

Usage

rsc-markdown is designed for Next.js, Remix, and React 19.

Server Component:

'use server';

import Markdown from 'rsc-markdown';

const markdownContent = ` # Welcome to rsc-markdown This is a **powerful** library for rendering markdown in React Server Components. `;

function MyComponent() {
  return <Markdown markdown={markdownContent} />;
}

Client Component:

'use client';

import Markdown from 'rsc-markdown';

const markdownContent = ` # Welcome to rsc-markdown This is a **powerful** library for rendering markdown in React Server Components. `;

function MyComponent() {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <Markdown markdown={markdownContent} />
    </Suspense>
  );
}

With Api:

'use server';

import Markdown from 'rsc-markdown';

const prisma = new PrismaClient();

export default async function MyComponent() {
  const markdown = await fetch('/api/markdown').then((res) => res.text());

  return <Markdown markdown={markdown} />;
}

Props

• markdown: The markdown content to be rendered. (Required)
• options: Configuration options (Optional):
  • trimWhiteSpace: Trims leading white space from each line in the markdown content.
  • gfm: Enables GitHub Flavored Markdown.
  • syntaxHighlighting: Enables syntax highlighting for code blocks.
  • components: An optional object to override default HTML elements with custom React components.

Custom Components

You can replace standard markdown elements with your custom components. For example, to use a custom component for rendering links:

import Markdown from 'rsc-markdown';
const components = {
  a: ({ href, children }) => (
    <a href={href} style={{ color: 'red' }}>
      {children}
    </a>
  ),
};
const markdownContent = `[Custom Link](https://example.com)`;
function MyComponent() {
  return <Markdown markdown={markdownContent} components={components} />;
}

Note

Remember, rsc-markdown is a server component and cannot use any hooks or functions that start with the word use or have event handlers. It's designed to render static markdown content efficiently on the server side, enhancing the performance and SEO of your React applications.
