MD変換の例

pages/test3/App.tsx: dangerouslySetInnerHTML　使う例です

App.tsx

import React from 'react';
import { marked } from 'marked';

const testMD = `
### hoge
***
* 123
* 145
***
* CCC
`
//
export default function Page(props: any) {
    const content = marked.parse(testMD);
console.log(content);
    //
    return (
    <div>
        <h1 className="text-4xl font-bold">Test3</h1>
        <hr className="my-2" />
        <pre dangerouslySetInnerHTML={{ __html: content }} />
        <hr className="my-2" />
        {/* JS */}
        {import.meta.env.PROD ? (
            <script type="module" src="/static/Page2.js"></script>
        ) : (
            <script type="module" src="/src/client/Page2.ts"></script>
        )}        
    </div>
    )
}
