Here you will find a simple Express web app illustrating how to authenticate Twitch API calls using the OAuth authorization code flow. This sample uses Express, Passport, and Handlebars.

After you have cloned this repository, use npm to install dependencies.

$ npm install

Before running this sample, you will need to set four configuration fields at the top of index.js:

1. TWITCH_CLIENT_ID - This is the Client ID of your registered application. You can register a new application at [https://dev.twitch.tv/dashboard/apps]
2. TWITCH_CLIENT_SECRET - This is the secret generated for you when you register your application, do not share this. In a production environment, it is STRONGLY recommended that you do not store application secrets on your file system or in your source code.
3. SESSION_SECRET - This is the secret Express session middleware uses to sign the session ID cookie.
4. CALLBACK_URL - This is the callback URL you supply when you register your application. To run this sample locally use [http://localhost:3000/auth/twitch/callback]

Optionally, you may modify the requested scopes when the /auth/twitch route is defined.

After setting these fields, you may run the server.

$ node index.js

From here you can add as many routes, views, and templates as you want and create a real web app for Twitch users.
