Description

It would be useful for people to be able to load schemas on the fly (lazily at runtime) instead of binding them in a view. This could be used for dynamic graphql servers, when you need to serve a different schema per user context.

express-graphql does this by allowing the schema to be resolved lazily. Similar to this example: https://github.com/graphql/express-graphql/issues/791 Note that in this case the options: Options is either an Object or a promise returning an object.

Apollo does not offer this by default, only by using a dangerous hack (which unfortunately is used in production in a few places that I've seen):
