GraphQL with Strapi 4: How to query all components as unstructured JSON?

[paulwellnerbou]

We are migrating our CMS from Strapi 3 to Strapi 4, adjusting our GraphQL queries.

We have some dynamic zones (e.g. Components), which we just want to query as unstructured JSON. So we defined this in our schema in gatsby-node.js:

exports.createSchemaCustomization = ({ actions, schema }) => {
    const { createTypes } = actions;

    const typeDefs = [
        schema.buildObjectType({
            name: 'StrapiMedia',
            fields: {
                id: { type: 'String!' },
                ...,
                localFile: {
                    type: 'File',
                    resolve: (source, args, context, info) => {
                        return context.nodeModel.getNodeById({
                            id: source.localFile___NODE,
                            type: 'File'
                        })
                    }
                },
            },
            extensions: {
                infer: true
            }
        }),
        `
        type StrapiEntity implements Node {
            title: String
            smallImage: StrapiMedia
            largeImage: StrapiMedia
            strapiChildren: [StrapiEntity]
            Components: [JSON]
            locale: String
            localizations: [StrapiEntitiesLocalizations]
        }
        `
    ];
    createTypes(typeDefs);
}

So we could just mention this field in our query, without adding any subfields:

graphql(`query {
    allStrapiEntity {
        nodes {
            identifier
            Components
        }
    }
}`);

This does not work with Strapi 4 any more. I would have to do something like this in the query:

graphql(`query {
    allStrapiEntity {
        nodes {
            identifier
            Components {
            ... on STRAPI__COMPONENT_COMPONENT_1 { ...all fields }
            ... on STRAPI__COMPONENT_COMPONENT_2 { ...all fields }
            ... on STRAPI__COMPONENT_COMPONENT_3 { ...all fields }
            ...
            ... on STRAPI__COMPONENT_COMPONENT_n { ...all fields }
            }
        }
    }
}`);

Which I definitely do not want, as I don't want to adjust the queries each time I change the data model in Strapi.

And even then, how do I query lists/relations that are part of this component?

Is there a way to just say "Give me all components as JSON", as before?

I already considered dropping GraphQL completely, but I do not want to loose the preview feature. So unfortunately I have to use GraphQL.
