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:

```elixir
def deps do
  [{:ueberauth_auth0, "~> 0.1"}]
end
```

3. Ensure ueberauth_auth0 is started before your application:

```elixir
def application do
  [applications: [:ueberauth_auth0]]
end
```

4. Add Auth0 to your Überauth configuration:

```elixir
config :ueberauth, Ueberauth,
providers: [
  auth0: {Ueberauth.Strategy.Auth0, []}
]
```

5. Update your provider configuration:

```elixir
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:

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

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

```elixir
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:

```elixir
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
