Does AEM 6.5.21 allows to customize GraphQL schema or use GraphQL resolvers?

Question

I want to validate if is it possible to customize GraphQL schemas or use GraphQL resolvers while using GraphQL API for Content Fragments in AEM 6.5.21. Right now we can fetch CF data using a persisted query and it returns all the data just like it exists in the JCR, but we would like to transform some fields before providing the response: for example, for a string multifield (String[]) that is returning data like this: {
  "data": {
    "sampleCFByPath": {
      "item": {
        "title": "Sample CF",
        "section": [
          "{\"field1\":\"value 1\",\"field2\":false}"
        ]
      }
    }
  }
}​  We need to transform it to be a JSON array like this: {
  "data": {
    "sampleCFByPath": {
      "item": {
        "title": "Sample CF",
        "section": [
          {
            "field1": "value 1",
            "field2": false
          }
        ]
      }
    }
  }
} Thanks in advance

Based on the sample which you shared it does not look like a standard cf multifield but rather some customized version of it, hence it might be easier to process the graphql response on front end.

The js code which I shared will be used by the application consuming your graphql query. So, you can check the place where the graphql query is being invoked (For e.g in some headless app or within AEM) and then can easily process the response as per your requirements.

Hope this helps.

Hi @elkinto

Is your fragment property is multifield like below ?

Please try below in graphQL query editor for multifield property. It should give desired output like you're expecting

multifieldName {
   name   // name property
   multi // string[] property 
}

Hope this helps
