What API should I use to access Redux store through graphql query and update the store back

I’m querying Google Analytics and creating a node with data from it like this:

exports.sourceNodes = ({ actions, createNodeId, createContentDigest }) => {
    const data = analytics().then((data) => {
        const node = {
            hits: data,
            internal: {
                type: "AnalyticsNode",
            }
            ...
        };
        createNode(node);
    });
};

then I need to transform this data using information from other nodes, say posts, so I can query these nodes and transform the data inside createPages:

exports.createPages = async ({ graphql, actions }) => {
    const { createPage } = actions;

    const result = await graphql(`
        {
            allPost() { ... }
	    analyticsNode() { ... }	
         }
    `);

    const resultingData = mixData();

and now I need to send this resultingData back to the store to make it queryable inside pages. How do I do that?

If the page is static, I could send it through context inside create pages:

    createPage({
        path: 'analytics',
        component: path.resolve(`./src/templates/analytics.js`),
        context: {
            resultingData
        }
    });

but this wouldn’t work for for dynamic pages, i.e. /app pages rendered using a Router.

@maxkoretskyi OK, now I understand a bit better what you’re after. A custom resolver is what you need. Attach as a new field on Analytics, and inside the resolver you can access Post and handle mixData. See https://www.gatsbyjs.org/docs/schema-customization/#createresolvers-api

Hi @maxkoretskyi. No, there’s not currently a way to access that data at runtime. It’s something people have requested, but couldn’t be implemented without running a live GraphQL server for each site.

I’m going to close this now. If you have any more questions, let me know.
