Usage

Schemas should use Absinthe.Relay.Schema, optionally providing what flavor of Relay they'd like to support (:classic or :modern):

defmodule Schema do
  use Absinthe.Schema
  use Absinthe.Relay.Schema, :modern

  # ...

end

For a type module, use Absinthe.Relay.Schema.Notation

defmodule Schema do
  use Absinthe.Schema.Notation
  use Absinthe.Relay.Schema.Notation, :modern

  # ...

end

Note that if you do not provide a flavor option, it will choose the default of :classic, but warn you that this behavior will change to :modern in absinthe_relay v1.5.

See the documentation for Absinthe.Relay.Node, Absinthe.Relay.Connection, and Absinthe.Relay.Mutation for specific usage information.

Node Interface

Relay requires an interface, "Node", be defined in your schema to provide a simple way to fetch objects using a global ID scheme.

See the Absinthe.Relay.Node module documentation for specific instructions on how do design a schema that makes use of nodes.

Connection

Relay uses Connection (and other related) types to provide a standardized way of slicing and paginating a one-to-many relationship.

Support in this package is designed to match the Relay Cursor Connection Specification.

See the Absinthe.Relay.Connection module documentation for specific instructions on how do design a schema that makes use of nodes.

Mutation

Relay supports mutation via a contract involving single input object arguments (optionally for Relay Modern) with client mutation IDs (only for Relay Classic).

See the Absinthe.Relay.Mutation module documentation for specific instructions on how to design a schema that makes use of mutations.

Supporting the Babel Relay Plugin

To generate a schema.json file for use with the Babel Relay Plugin, run the absinthe.schema.json Mix task, built-in to Absinthe.

In your project, check out the documentation with:

mix help absinthe.schema.json
