Plug support for Absinthe, the GraphQL toolkit for Elixir.

Please see the website at http://absinthe-graphql.org.

Installation

Install from Hex.pm:

def deps do
  [{:absinthe_plug, "~> 1.5"}]
end

Note: Absinthe.Plug requires Elixir 1.10 or higher.

Absinthe.Plug also requires a JSON codec. Jason and Poison work out of the box.

    {:absinthe_plug, "~> 1.5"},
    {:jason, "~> 1.0"}

Usage

In your MyAppWeb.Router module add:

plug Plug.Parsers,
  parsers: [:urlencoded, :multipart, :json, Absinthe.Plug.Parser],
  pass: ["*/*"],
  json_decoder: Jason

plug Absinthe.Plug,
  schema: MyAppWeb.Schema

If you want Absinthe.Plug to serve only a particular route, configure your MyAppWeb.Router like:

plug Plug.Parsers,
  parsers: [:urlencoded, :multipart, :json, Absinthe.Plug.Parser],
  pass: ["*/*"],
  json_decoder: Jason

forward "/api",
  to: Absinthe.Plug,
  init_opts: [schema: MyAppWeb.Schema]

For more information, see the API documentation for Absinthe.Plug.

Phoenix.Router

If you are using Phoenix.Router, forward expects different arguments:

Plug.Router

forward "/graphiql",
  to: Absinthe.Plug.GraphiQL,
  init_opts: [
    schema: MyAppWeb.Schema,
    interface: :simple
  ]

Phoenix.Router

forward "/graphiql",
  Absinthe.Plug.GraphiQL,
  schema: MyAppWeb.Schema,
  interface: :simple

For more information see Phoenix.Router.forward/4.

GraphiQL

To add support for a GraphiQL interface, add a configuration for Absinthe.Plug.GraphiQL:

forward "/graphiql",
  to: Absinthe.Plug.GraphiQL,
  init_opts: [schema: MyAppWeb.Schema]

See the API documentation for Absinthe.Plug.GraphiQL for more information.
