Example of dynamically creating JSON-LD to create Google Rich Cards in Meteor?

I would like to see if somebody could post an example of how to dynamically create a JSON-LD to create a google rich card? I had read issues here and stack overflow posts and I think it’s possible but I haven’t figured it out how. I would really appreciate if somebody could show me an example of how to implement this.

This is what I’ve so far:

<Helmet> <script type="application/ld+json"> { { “@context”: “http://schema.org”, “@type”: “WebSite”, “name”: ${this.state.title.toString()}, “url”: ${this.state.url.toString()}, “description”: ${this.state.body.toString()}, “image”: ${this.state.imgUrlGal.toString()} } } </script> </Helmet>

Thanks
