Class: GraphQL::Types::Relay::BaseConnection

Inherits:

Schema::Object

• Object
• Schema::Member
• Schema::Object
• GraphQL::Types::Relay::BaseConnection

Includes:

ConnectionBehaviors

Defined in:

lib/graphql/types/relay/base_connection.rb

Overview

Use this to implement Relay connections, or take it as inspiration for Relay classes in your own app.

You may wish to copy this code into your own base class, so you can extend your own BaseObject instead of GraphQL::Schema::Object.

Examples:

Implementation a connection and edge

class BaseObject < GraphQL::Schema::Object; end

# Given some object in your app ...
class Types::Post < BaseObject
end

# Make a couple of base classes:
class Types::BaseEdge < GraphQL::Types::Relay::BaseEdge; end
class Types::BaseConnection < GraphQL::Types::Relay::BaseConnection; end

# Then extend them for the object in your app
class Types::PostEdge < Types::BaseEdge
  node_type Types::Post
end

class Types::PostConnection < Types::BaseConnection
  edge_type Types::PostEdge,
            edges_nullable: true,
            edge_nullable: true,
            node_nullable: true,
            nodes_field: true

  # Alternatively, you can call the class methods followed by your edge type
  # edges_nullable true
  # edge_nullable true
  # node_nullable true
  # has_nodes_field true
  # edge_type Types::PostEdge
end
