# Überauth Twitch.tv
> Twitch.tv OAuth2 strategy for Überauth.
## Installation
1. Setup your application at [Twitch.tv Developer](https://www.twitch.tv/kraken/oauth2/clients/new).
1. Add `:ueberauth_twitch_tv` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:ueberauth_twitch_tv, "~> 0.3.0"}]
end
```
1. Add the strategy to your applications:
```elixir
def application do
[applications: [:ueberauth_twitch_tv]]
end
```
1. Add Twitch.tv to your Überauth configuration:
```elixir
config :ueberauth, Ueberauth,
providers: [
twitchtv: {Ueberauth.Strategy.TwitchTv, []}
]
```
1. Update your provider configuration:
```elixir
config :ueberauth, Ueberauth.Strategy.TwitchTv.OAuth,
client_id: System.get_env("TWITCH_TV_CLIENT_ID"),
client_secret: System.get_env("TWITCH_TV_CLIENT_SECRET")
```
1. Include the Überauth plug in your controller:
```elixir
defmodule MyApp.AuthController do
use MyApp.Web, :controller
plug Ueberauth
...
end
```
1. 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
```
1. You controller needs to implement callbacks to deal with `Ueberauth.Auth` and `Ueberauth.Failure` responses.
For an example implementation see the [Überauth Example](https://github.com/ueberauth/ueberauth_example) application.
## Calling
Depending on the configured url you can initial the request through:
/auth/twitchtv
Or with options:
/auth/twitchtv?scope=user,public_repo
By default the requested scope is "user,public\_repo". Scope can be configured either explicitly as a `scope` query value on the request path or in your configuration:
```elixir
config :ueberauth, Ueberauth,
providers: [
twitchtv: {Ueberauth.Strategy.TwitchTv, [default_scope: "user,public_repo,notifications"]}
]
```
