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

Inherits:

Schema::Object

• Object
• Schema::Member

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

# 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)
  has_nodes_field(true)
end
