Support for the Relay framework from Elixir, using the Absinthe package.

Install from Hex.pm:

def deps do
  [
    {:absinthe_relay, "~> 1.5.0"}
  ]
end

Note: Absinthe.Relay requires Elixir 1.11 or higher.

See CHANGELOG for upgrade steps between versions.

You may want to look for the specific upgrade guide in the Absinthe documentation.

See "Usage," below, for basic usage information and links to specific resources.

• Absinthe.Relay hexdocs.
• For the tutorial, guides, and general information about Absinthe-related projects, see http://absinthe-graphql.org.

See the GitHub organization.

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.

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.

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.

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.

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
