React Structured Data

React Structured Data provides an easy way to add structured data to your React apps. Structured data is a standardized format for providing information about a page and classifying the page content. This library follows guidelines specified at http://schema.org/.

Installation

Yarn

yarn add react-structured-data

NPM

npm install react-structured-data --save

Code Example

The following JSX:

  <JSONLD>
    <Product name="Product Name">
      <AggregateRating ratingValue={4.3} reviewCount={197}/>
      <GenericCollection type="review">
        <Review name="It's awesome" reviewBody="This is Great! My family loves it" datePublished="11/22/1963">
          <Author name="Jerry"/>
          <Location name="Chicago, IL"/>
          <Rating ratingValue={5} />
        </Review>
        <Review name="Very cool" reviewBody="I like this a lot. Very cool product" datePublished="11/22/1963">
          <Author name="Cool Carl"/>
          <Location name="Chicago, IL"/>
          <Rating ratingValue={4} />
        </Review>
      </GenericCollection>
    </Product>
  </JSONLD>

will add the following to your markup (will be minified):

<script type="application/ld+json">
  {
    "@context":"https://schema.org/",
    "@type":"Product",
    "name":"Product Name",
    "aggregateRating": {
      "@type":"AggregateRating",
      "ratingValue":4.3,
      "reviewCount":197
    },
    "review":[
      {
        "@type":"Review",
        "datePublished":"11/22/1963",
        "reviewBody":"This is Great! My family loves it",
        "name":"It's awesome",
        "author": {
          "@type":"Person",
          "name":"Jerry"
        },
        "locationCreated": {
          "@type":"AdministrativeArea",
          "name":"Chicago, IL"
        },
        "reviewRating": {
          "@type": "Rating",
          "ratingValue": 5
        }
      },
      {
        "@type":"Review",
        "datePublished":"11/22/1963",
        "reviewBody":"I like this a lot. Very cool product",
        "name":"Very cool",
        "author":{
          "@type":"Person",
          "name":"Cool Carl"
        },
        "locationCreated": {
          "@type":"AdministrativeArea",
          "name":"Chicago, IL"
        },
        "reviewRating": {
          "@type": "Rating",
          "ratingValue": 4
        }
      }
    ]
  }
</script>

Reference

PropTypes

Generic Component PropTypes

PropType Value Description
type String The @type description in the json-ld body: "@type": "Product"
jsonldtype String The value of the @type description in the json-ld body: "@type": "Product"
schema Object (json) This should be the schema that you want for your structured data node: {name: "It is awesome", reviewBody: "This is great!"}

JSONLD node propTypes

PropType Value Description
dangerouslyExposeHtml Boolean Set this to render the json within script tag using dangerouslySetInnerHTML

Schema node PropTypes

PropType Value Description
parentID String Sets the id of the schema that becomes a reference that the children point to "@id": "product-x"
id String similar to parentID but uses the ID on itself

Preset Components

There are several preset schema components that can be used

  • AggregateRating
  • Answer
  • Author
  • ItemReviewed
  • Location
  • Product
  • Question
  • Rating
  • Review

If you would like to use a component that is not listed, simply use the Generic component and add the prop jsonldtype. Generic and GenericCollection allow you to add your own structured data type.

For example, If Review preset didn't exist, you could write:

<JSONLD>
  <Generic type="review" jsonldtype="Review" schema={{name: "It is awesome", reviewBody: "This is great!"}}>
    <Generic type="itemReviewed" jsonldtype="Product" schema={{"@id":"product-x"}} />
    <Generic type="author" jsonldtype="Person" schema={{name: "Cool Carl"}}/>
    <Generic type="locationCreated" jsonldtype="AdministrativeArea" schema={{name: "Chicago, IL"}}/>
  </Generic>
</JSONLD>

This will output (minified):

<script type="application/ld+json">
  {
    "@context": "http://schema.org/",
    "@type": "Review",
    "name": "It is awesome",
    "reviewBody": "This is great!",
    "itemReviewed": {
      "@type": "Product",
      "@id": "product-x"
    },
    "author": {
      "@type": "Person",
      "name": "Cool Carl"
    },
    "locationCreated": {
      "@type": "AdministrativeArea",
      "name": "Chicago, IL"
    }
  }
</script>

This may seem not as ideal as using the presets, but this allows completely customizable structured data. There will also be more preset components to come in future releases to make implementation easier so stay tuned!
