end

Add it to your applications configuration in mix.exs, too:

def application do

Usage

Schemas should use Absinthe.Relay.Schema, eg:

defmodule Schema do
  use Absinthe.Schema
  use Absinthe.Relay.Schema

  # ...

end

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

defmodule Schema do
  use Absinthe.Schema.Notation
  use Absinthe.Relay.Schema.Notation

  # ...

end

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 with and client mutation IDs.

Support in this package is designed to match the Relay Input Object Mutations Specification.

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
