Überauth Patreon

Patreon OAuth2 strategy for Überauth.

Installation

1. Setup your application in Patreon Development Dashboard https://www.patreon.com/portal/registration/register-clients

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

   def deps do
     [{:ueberauth_patreon, "~> 1.0"}]
   end

3. Add Patreon to your Überauth configuration:

   config :ueberauth, Ueberauth,
     providers: [
       patreon: {Ueberauth.Strategy.Patreon, [default_scope: "identity[email] identity"]},
     ]

4. Update your provider configuration:

   config :ueberauth, Ueberauth.Strategy.Patreon.OAuth,
     client_id: System.get_env("PATREON_CLIENT_ID"),
     client_secret: System.get_env("PATREON_CLIENT_SECRET"),
     redirect_uri: System.get_env("PATREON_REDIRECT_URI")

5. Include the Überauth plug in your router pipeline:

   defmodule TestPatreonWeb.Router do
     use TestPatreonWeb, :router
   
     pipeline :browser do
       plug Ueberauth
       ...
      end
   end

6. Add the request and callback routes:

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

7. Create a new controller or use an existing controller that implements callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses from Patreon.

     defmodule TestPatreonWeb.AuthController do
       use TestPatreonWeb, :controller
   
       def callback(%{assigns: %{ueberauth_failure: _fails}} = conn, _params) do
         conn
         |> put_flash(:error, "Failed to authenticate.")
         |> redirect(to: "/")
       end
   
       def callback(%{assigns: %{ueberauth_auth: auth}} = conn, _params) do
         case UserFromAuth.find_or_create(auth) do
           {:ok, user} ->
             conn
             |> put_flash(:info, "Successfully authenticated.")
             |> put_session(:current_user, user)
             |> configure_session(renew: true)
             |> redirect(to: "/")
   
           {:error, reason} ->
             conn
             |> put_flash(:error, reason)
             |> redirect(to: "/")
         end
       end
     end
