Any example for Relay Node inheritance and Connections?

[Vani-gurnani]

This is a great library, was wondering if there is implement types from Node which is required for graphql-relay and the connections.

var userType = new GraphQLObjectType({
name: 'User',
description: 'A person who uses our app',
fields: () => ({
id: globalIdField('User'),
firstName: {
type: GraphQLString,
description: "First Name of user"
},
lastName: {
type: GraphQLString,
description: "Last Name of user"
}
}),
interfaces: [nodeInterface],
});

//How to specify interfaces:[nodeInterface] ?

Personally i haven't used Relay, so I'm not really sure. Maybe some other folks know better though

@Vani-gurnani interfaces are determined by just writing them in the graphql type definitions, and then adding a resolveType on the interface definition object:

interface Node {
  id: ID!
}

type User implements Node {
  id: ID!
  firstName: String,
  lastName: String
}

type Query {
  node(id: ID!): Node
}

{
  Query: {
    node(root, args) { 
      // put resolver here 
    }
  },
  User: {
    id: globalIdField('User')
  },
  Node: {
    resolveType(value) {
      if (isUser(value)) {
        return 'User'
      }
    }
  }
}
