Package Exports

nuxt-jsonld

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (nuxt-jsonld) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

Make a jsonld method to your Vue components and return structured data object.

<template>
  ...
</template>

<script>
export default {
  data() {
    return {
      breadcrumbs: [
        {
          url: 'https://example.com',
          text: 'top page',
        },
        {
          url: 'https://example.com/foo',
          text: 'foo',
        },
        {
          url: 'https://example.com/foo/bar',
          text: 'bar',
        },
      ],
    };
  },
  jsonld() {
    const items = this.breadcrumbs.map((item, index) => ({
      '@type': 'ListItem',
      position: index + 1,
      item: {
        '@id': item.url,
        name: item.text,
      },
    }));
    return {
      '@context': 'http://schema.org',
      '@type': 'BreadcrumbList',
      itemListElement: items,
    };
  },
};
</script>

🎉 You will get the jsonld tag! 🎉

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "BreadcrumbList",
  "itemListElement": [
    {
      "@type": "ListItem",
      "position": 1,
      "item": {
        "@id": "https://example.com",
        "name": "top page"
      }
    },
    {
      "@type": "ListItem",
      "position": 2,
      "item": {
        "@id": "https://example.com/foo",
        "name": "foo"
      }
    },
    {
      "@type": "ListItem",
      "position": 3,
      "item": {
        "@id": "https://example.com/foo/bar",
        "name": "bar"
      }
    },
  ]
}
</script>

If you do not want to make jsonld tag, just return null;

<script>
export default {
  props: ['foo'],
  jsonld() {
    if (!this.foo) {
      return null;
    }

    return {
      '@context': 'http://schema.org',
      '@type': 'SomeType',
      body: foo,
    };
  },
};
</script>
