Dynamically Render React Components into Your ReactMarkDown

If you have a Markdown file processed by react-markdown and you want to dynamically render React components into certain placeholders later, you can follow these general steps:

Identify Placeholder Syntax in Markdown:
- Define a specific syntax in your Markdown file to indicate where placeholders for React components should go. For example, you might use a special syntax like {{ComponentName}} or any other syntax that is unlikely to conflict with typical Markdown content.

# My Markdown File

This is some content.

{{DynamicComponent1}}

More content.

{{DynamicComponent2}}

Process Markdown Content:

Use react-markdown to process the Markdown content, but capture the information about placeholders during this process. You can use a custom plugin for this.

import ReactMarkdown from 'react-markdown';
import { useMemo } from 'react';

const MyMarkdown = ({ markdownContent, dynamicComponents }) => {
  const renderers = useMemo(() => {
    return {
      text: (props) => {
        const { value } = props;
        // Check if the text contains a placeholder
        const match = value.match(/{{(.*?)}}/);
        if (match) {
          const componentName = match[1].trim();
          const DynamicComponent = dynamicComponents[componentName];
          if (DynamicComponent) {
            return <DynamicComponent />;
          }
        }
        return <span>{props.children}</span>;
      },
    };
  }, [dynamicComponents]);

  return <ReactMarkdown source={markdownContent} renderers={renderers} />;
};

export default MyMarkdown;

Render Dynamic Components:

Use the MyMarkdown component in your application, passing the Markdown content and an object containing React components that correspond to the placeholders.

import MyMarkdown from './MyMarkdown';
import DynamicComponent1 from './DynamicComponent1';
import DynamicComponent2 from './DynamicComponent2';

const dynamicComponents = {
  DynamicComponent1,
  DynamicComponent2,
};

const markdownContent = `
# My Markdown File

This is some content.

{{DynamicComponent1}}

More content.

{{DynamicComponent2}}
`;

const App = () => {
  return <MyMarkdown markdownContent={markdownContent} dynamicComponents={dynamicComponents} />;
};

export default App;

Render Dynamically Loaded Components:

Later in your application, dynamically load the components you want to render into the placeholders.

// Dynamically load components and update state or Redux store
import { useEffect, useState } from 'react';

const App = () => {
  const [loadedComponents, setLoadedComponents] = useState({});

  useEffect(() => {
    import('./path/to/DynamicComponent1').then((module) => {
      setLoadedComponents((prev) => ({ ...prev, DynamicComponent1: module.default }));
    });

    import('./path/to/DynamicComponent2').then((module) => {
      setLoadedComponents((prev) => ({ ...prev, DynamicComponent2: module.default }));
    });
  }, []);

  return (
    <MyMarkdown
      markdownContent={markdownContent}
      dynamicComponents={{ ...loadedComponents }}
    />
  );
};

This way, you have a flexible system where you can define placeholders in your Markdown file and dynamically render React components into those placeholders later in your application. Adjust the syntax and implementation based on your specific requirements and application architecture.
