This adds the WPGraphQL for Yoast SEO to the extensions page registry.

Smoke Tests

I've verified basic functionality with the plugin.

With the following environment:

WordPress 6.7.1
PHP: 8.2.23
WPGraphQL v1.29.3
WPGraphQL Yoast SEO Addon v4.23.2
Yoast SEO v24.2

I was able to create a post with some SEO data:

And I was able to query the SEO data for the post:

Here's the full query I used:

query GetPostWithSEOFields {
  post(id:83 idType:DATABASE_ID) {
    id
    databaseId
    seo {
      ...PostTypeSEO
    }
  }
}

fragment PostTypeSEO on PostTypeSEO {
  canonical
  metaKeywords
  metaDesc
  title
}

And the payload I received:

{
  "data": {
    "post": {
      "id": "cG9zdDo4Mw==",
      "databaseId": 83,
      "seo": {
        "canonical": "http://wpgraphql.local/test-slug/",
        "metaKeywords": "",
        "metaDesc": "Test meta description",
        "title": "SEO Post Test - wpgraphql"
      }
    }
  }
}

Conclusion

The plugin appears to work as advertised, provides documentation, has regular maintenance and offers support via WordPress.org and Github
