The code written in JSX Fragments is not rendering after fetching it. It is just displayed as it is written in an array of objects. Postdata.js file is containing an array of objects. I am trying to fetch the data of blog articles using getStaticProps and getStaticPaths.

Answer 1

The first solution can be using dangerouslySetInnerHTML
<div dangerouslySetInnerHTML={{__html: post.content}} />
But as for the security problem, it will lead you to cross-site scripting (XSS) attack. So I'd propose you use html-react-parser that will help you to render a string as JSX safely.
import parse from 'html-react-parser';
const Post = ({post}) => {
return (
<>
{parse(post.content)}
</>
)
}

You have to use dangerouslySetInnerHTML in React, it is equivalent to seting innerHTML in vanilla JS refer this React.js: Set innerHTML vs dangerouslySetInnerHTML
