Überauth Auth0

Auth0 OAuth2 strategy for Überauth.

Installation

  1. Set up your Auth0 application at Auth0 dashboard

  2. Add ueberauth_auth0 to your list of dependencies in mix.exs:

        def deps do
          [{:ueberauth_auth0, "~> 0.1"}]
        end
        ```
    
  3. Ensure ueberauth_auth0 is started before your application:

        def application do
          [applications: [:ueberauth_auth0]]
        end
        ```
    
  4. Add Auth0 to your Überauth configuration:

        config :ueberauth, Ueberauth,
        providers: [
          auth0: {Ueberauth.Strategy.Auth0, []}
        ]
        ```
    
  5. Update your provider configuration:

        config :ueberauth, Ueberauth.Strategy.Auth0.OAuth,
          domain: System.get_env("AUTH0_DOMAIN"),
          client_id: System.get_env("AUTH0_CLIENT_ID"),
          client_secret: System.get_env("AUTH0_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
        ```
    
  8. Create the controller to handle request and callback:

        def request(conn, _params) do
          render(conn, "login.html", callback_url: Ueberauth.Strategy.Helpers.callback_url(conn))
        end
        
        def callback(%Plug.Conn{assigns: %{ueberauth_failure: fails}} = conn, _params) do
          conn
          |> put_flash(:error, hd(fails.errors).message)
          |> render("login.html", callback_url: Ueberauth.Strategy.Helpers.callback_url(conn))
        end
    
        def callback(%Plug.Conn{assigns: %{ueberauth_auth: auth}} = conn, _params) do
          # auth = %Ueberauth.Auth{
          #   credentials: %Ueberauth.Auth.Credentials{
          #     token: token,
          #     token_type: token_type,
          #     other: %{"id_token" => id_token}
          #   }
          # }
          redirect(conn, to: private_page_path(conn, :index))
        end
