Überauth Discord

Discord OAuth2 strategy for Überauth.

For additional documentation on Discord’s OAuth implementation see discord-oauth2-example.

Installation

1. Setup your application at Discord Developers.

2. Add :ueberauth_discord to your list of dependencies in mix.exs:

    def deps do
      [{:ueberauth_discord, "~> 0.5"}]
    end

3. Add the strategy to your applications:

    def application do
      [applications: [:ueberauth_discord]]
    end

4. Add Discord to your Überauth configuration:

    config :ueberauth, Ueberauth,
      providers: [
        discord: {Ueberauth.Strategy.Discord, []}
      ]

5. Update your provider configuration:

   config :ueberauth, Ueberauth.Strategy.Discord.OAuth,
     client_id: System.get_env("DISCORD_CLIENT_ID"),
     client_secret: System.get_env("DISCORD_CLIENT_SECRET")

6. Include the Überauth plug in your controller:

   defmodule MyApp.AuthController do
     use MyApp.Web, :controller
     plug Ueberauth
     ...
   end

7. Create the request and callback routes if you haven’t already:

   scope "/auth", MyApp do
     pipe_through :browser
   
     get "/:provider", AuthController, :request
     get "/:provider/callback", AuthController, :callback
   end

   And make sure to set the correct redirect URI(s) in your Discord application to wire up the callback.

8. Your controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

For an example implementation see the Überauth Example application.

Calling

Depending on the configured url you can initialize the request through:

/auth/discord

Or with options:

/auth/discord?scope=identify%20email

By default the requested scope is “identify”. Scope can be configured either explicitly as a scope query value on the request path or in your configuration:

config :ueberauth, Ueberauth,
  providers: [
    discord: {Ueberauth.Strategy.Discord, [default_scope: "identify email connections guilds"]}
  ]

Additionally you can now specify the prompt param to pass to Discord:

config :ueberauth, Ueberauth,
  providers: [
    discord: {Ueberauth.Strategy.Discord, [
      default_scope: "identify email connections guilds",
      prompt: "none"
    ]}
  ]
