Is there a way to do Automatic Persisted Queries with this toolkit? about gatsby-graphql-toolkit

[vladar]

Hey, thanks for reaching out!

The toolkit doesn't really care how you execute GraphQL queries. It just expects you to provide a function:

execute({ query, operationName, variables })

that returns a standard GraphQL response (actually a Promise for this response):

{
  data: {
    // response data
  },
  errors: []
}

You can use persisted queries or just send a full query. That is totally up to you. We do provide a default implementation of such execute function but you can easily swap it with your own.

If you want you can use Apollo links inside this function:

const { toPromise, execute as apolloExecute } = require('apollo-link');

const myApolloLink = createPersistedQueryLink({useGETForHashedQueries: true})
  .concat(createHttpLink({ uri: `https://${process.env.DATA_SOURCE_URL}/graphql`, fetch: fetch }))

async function execute({ query, operationName, variables }) {
  return toPromise(apolloExecute(myApolloLink , { query, operationName, variables }))
}

But as for me, apollo links introduce unnecessary overhead. Still, you can use them if you want.

Thanks @vladar! I see how I would set a custom execute when writing a source plugin using the toolkit. Do you expect that a site using your new gatsby-source-drupal-graphql would eventually be able to also override just the execute function from configuration?

[vladar]

I think yes. It makes sense to expose execute as an option. But it depends on how gatsby-source-drupal-graphql plugin will be implemented. So it's up to the plugin author to decide (I will just prepare an initial prototype for this).

sounds good! thanks @vladar.
