Haroen | JSON-LD with React

It’s not very hard to render json-ld with React, but since it’s something that’s not completely obvious; it looks like this:

const JsonLd = ({ data }) =>
  <script type="application/ld+json">

As noted by Iain Collins, in some cases you’ll need to set this as dangerous HTML like this:

const JsonLd = ({ data }) =>
    dangerouslySetInnerHTML={{ __html: JSON.stringify(data) }}

You can then use this component like this:

const data = {
  "@context": "http://json-ld.org/contexts/person.jsonld",
  "@id": "http://dbpedia.org/resource/John_Lennon",
  name: "John Lennon",
  born: "1940-10-09",
  spouse: "http://dbpedia.org/resource/Cynthia_Lennon"

const App = () =>
    <h1>Hello World</h1>
    <p>Lorem ipsum dolor sit amet</p>
    <JsonLd data={data} />

If you would have naively done this, you would expect to escape the brackets (\{), but it’s easier if you render the JSON.stringify output for the content of the script.
