How to get RelayJS to understand that a response from GraphQL is an array of items, not just a single item

Question

I have a GraphQL server running with a schema roughly like this:

type Card {
  id: String!
  name: String
}

type Query {
  card(name: String!): Card
  cards         


        

Answer 1

You probably want a @relay(plural: true) directive on your cards query fragment. There is an example of a plural field in action in the Star Wars example in the Relay repo.

If you care about pagination, though, you probably want a connection instead of a plural field. Connections are described in the Relay docs and implemented in graphql-relay-js.
