Support multiple GraphQL endpoints

Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. Ex. I’m always frustrated when […] our app has to hit multiple graphql endpoints. So this is either a question, or if it’s not possible a feature request.

The problem is that our app is using graphql endpoints from more than 1 url.

Describe the solution you’d like

The ability to specify the base url for a graphql.query.

Currently you define a route like this: graphql.query("MyQuery", () => {})

Not sure exactly what the best api is for this, but here are a couple of options.

1. something simple like

graphql.query("MyQuery", () => {}, {baseUrl:"http://example")
graphql.query("MyFooQuery", () => {}, {baseUrl:"http://foo")

1. something at a higher level that let’s us map multiple queries:

graphql.urls({
  "http://example": [
     graphql.query("MyQuery", () => {}), graphql.query("MyOtherQuery", () => {})
  ],
  "http://foo": [
     graphql.query("MyFooQuery", () => {}), graphql.query("MyOtherFooQuery", () => {})
  ]

1. open to other options? just need a way to handle multiple GQL endpoints. again, maybe there’s already a way and we can close this issue.

Describe alternatives you’ve considered A clear and concise description of any alternative solutions or features you’ve considered.

Additional context Add any other context or screenshots about the feature request here.

While it may sound compelling, graphql.link and rest.link would have significant design difference:

• graphql.link adds an extra layer of endpoint matching as a part of its predicate.
• rest already matches a request URL against a given endpoint, so the functionality of linking routes to a specific endpoint becomes a matter of a plain abstraction:

const github = (path: string) => {
  return `https://api.github.com/v3${path}`
}

rest.get(github(‘/repo/:owner/:name’), resolver)

I wish this was a way we solve a per-endpoint mocking for GraphQL as well, and it may become similar to this in the future.
