Graphql-continuations NPM

GraphQL Continuations

A WIP idea around a simpler approach to the problem solved by @defer. Adds a continuation field to the Query and any types implementing the Relay Node interface. Resolves the selection set underneath the query and executes.

npm i graphql-continuations

Try it out:

import { addContinuationsToSchema, memoryAdapter } from "graphql-continuations";

const schema = addContinuationsToSchema(myExistingSchema, {
  adapter: memoryAdapter(), // redisAdapter() or custom adapter intended for production usage
});
