researchgateReact 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 @researchgate/react-structured-data
NPM
npm install @researchgate/react-structured-data --save
Code Example
The following JSX:
<JSONLD>
<Product name="Product Name">
<AggregateRating ratingValue={4.3} reviewCount={197} />
<GenericNodeCollection 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!"} |
Schema node PropTypes
| PropType | Value | Description |
|---|---|---|
| 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
- QAPage
- Organisation
- Person
- Review
- Place
If you would like to use a component that is not listed, simply use the Generic component and add the prop type. Generic and GenericCollection allow you to add your own structured data type.
For example, If Review preset didn't exist, you could write:
<JSONLD>
<GenericNode
type="review"
jsonldtype="Review"
schema={{ name: 'It is awesome', reviewBody: 'This is great!' }}
>
<GenericNode
type="itemReviewed"
jsonldtype="Product"
schema={{ '@id': 'product-x' }}
/>
<GenericNode
type="author"
jsonldtype="Person"
schema={{ name: 'Cool Carl' }}
/>
<GenericNode
type="locationCreated"
jsonldtype="AdministrativeArea"
schema={{ name: 'Chicago, IL' }}
/>
</GenericNode>
</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!
