obsidian-callouts-markdown

Try the library at playground site 🚀

This library is for parsing Obsidian callout syntax in MDX. Transform your markdown syntax into callouts just like in Obsidian!

What is this library?

I write blog posts using Obsidian, and analyze markdown syntax using @mdx-js/react to operate my personal blog with Gatsby. Writing markdown posts with Obsidian allows you to post conveniently as if you were using services like velog or tistory. However, since Obsidian's callout syntax is not standard markdown syntax, callouts written in Obsidian just get parsed as blockquotes in the Gatsby blog. To alleviate this inconvenience, I created a library to help use the same callout syntax as Obsidian in Markdown.

Quick Start

1. Install the obsidian-callouts-markdown package.

npm install obsidian-callouts-markdown
yarn add obsidian-callouts-markdown

2. In the MDXProvider's components setting, map blockquote to ObsidianCallout.

It can be used in the same way in react-markdown. However, an additional rehype-raw plug-in is required to recognize the html tag inside the markdown.

import Post from '@/tests/posts.mdx';
import {MDXProvider} from '@mdx-js/react';
import {ObsidianCallout} from '@/package';

function App() {
  return (
    <MDXProvider
      components={{
        blockquote: ObsidianCallout,
      }}>
      <Post />
    </MDXProvider>
  );
}

3. You can now use callouts in markdown with the same syntax as in Obsidian.

Configuration

Types of Callouts

Types of Callout
normal ,note, abstract, summary, tldr, info, todo, tip, hint, important, success, check, done, question, help, faq, warning, caution, attention, danger, error, bug, example, quote, cite, normal

Supports all types of callouts that can be used in Obsidian. If you have not created a callout type, it is recognized as a normal type.

Customizing Callout Options

  const components = {
    blockquote: (props: HTMLAttributes<HTMLElement>) => (
      <ObsidianCallout
        {...props}
        options={{
          note: {
            icon: ErrorIcon,
            backgroundColor: '#fff',
            color: '#000',
          },
        }}
      />
    ),
  };

You can customize the icon, background color, and title text color of the callout using ObsidianCallout's options. The icon type is React.SVGProps<SVGSVGElement>.

Customizing Callout Components

  const components = {
    blockquote: (props: HTMLAttributes<HTMLElement>) => (
      <ObsidianCallout
        {...props}
        components={{
          note: CustomCallout,
        }}
      />
    ),
  };

You can define custom callout components using ObsidianCallout's components. Callout components can receive the following props.

props	type	require	description
type	string	false	The string in the [!type] part when writing a callout.
title	string	false	The title string written next to the type ([!type] title).
children	ReactNode	true	The main body of the callout.

Custom Callout Example

• code

const CustomCallout: React.FC<CustomCalloutComponentProps> = ({
                                                               type,
                                                               title,
                                                               children,
                                                            }) => {
   return (
           <div className="bg-teal-100 p-4 rounded-md">
              <div className="flex gap-2 text-teal-700 font-semibold mb-4">
                 <p>
                    [{type}] {title}
                 </p>
              </div>
              {children}
           </div>
   );
};

Adding Custom Callout Types

  const components = {
    blockquote: (props: HTMLAttributes<HTMLElement>) => (
      <ObsidianCallout
        {...props}
        components={{
          black: CustomCallout,
        }}
        options={{
           bigError: {
            icon: ErrorIcon,
            backgroundColor: 'red',
            color: 'yellow',
          },
        }}
      />
    ),
  };

When defining components or options, specifying a type key that does not exist adds that type of callout. In the code example above, new callout formats of type black and bigError are added. For callout types, any string except newline characters (\n) can be specified. If you customize the same callout type in both components and options, the settings applied in components will take effect.
