generateFaunaQuery

Given a GraphQLResolveInfo and a Fauna query that produces a result matching the output type of a GraphQL query or muation, this will generate a single FQL query that fetches fields and related data requested in the GraphQL query.

import { generateFaunaQuery } from "faunadb-graphql-lib"

{
    readPost: {
        type: PostType,
        args: {
            id: { type: PostIdType },
        },
        resolve: (_, { id }, context, info) => {
            const query = generateFaunaQuery(info, q.Get(id))
            return createClient()
                .query(query)
                .catch(err => {
                    console.log(err)
                    throw err
                })
        },
