I believe you can, you just have to use innerHTML as the property you pass in.

{ type: "application/ld+json", innerHTML: JSON.stringify({"hello": "world"})}

from react-helmet-async.

You're probably right -

if (attribute === TAG_PROPERTIES.INNER_HTML) {
newElement.innerHTML = tag.innerHTML;

I'll close this - it doesn't execute the script unless it is loading the page via SSR but that's another issue

For SSR do no forget to add the helmet.script.toString() in the rendered HTML.

SSR HTML:

<!doctype html>
<html lang="en">
  <head>
    ${helmet.title && helmet.title.toString()}
    ${helmet.meta && helmet.meta.toString()}
    ${helmet.script && helmet.script.toString()}
  </head>
  <body>
    <div id="app">${appStr}</div>
    <script src="/dist/bundle.js"></script>
  </body>
</html>

React component:

import React from 'react';
import PropTypes from 'prop-types';
import { Helmet } from 'react-helmet-async';

const Post = ({ post }) => {
  return (
    <div>
      <Helmet>
        <meta name="title" content={post.title} />
        <meta name="description" content={post.description} />
        <script type="application/ld+json">
          {`
           {
               "@context": "https://schema.org",
               "@type": "NewsArticle",
               "headline": "${post.title}",
               "datePublished": "${post.createdAt}",
               "dateModified": "${post.modifiedAt}"
           }
        `}
        </script>
      </Helmet>
      <div>
        <h1>{post.title}</h1>
        <p>{post.description}</p>
      <div>
    </div>      
  );
};

Post.propTypes = {
  post: PropTypes.object
};

export default Post;

Ensuring the text inside the <script /> tags is a string worked for me:

<script>{`console.log("hello world`}</script>
