Add Twitter Authentication to an Ember.js App with Torii

Torii is a lightweight authentication library for Ember.js. It supports various OAuth providers (such as Twitter, Google or FaceBook), and can be used to implement a pop-up-based OAuth redirect flow. It uses a session manager (for maintaining the current user), and adapters (to persist authentication state). In this article I will demonstrate how to implement sign in with Twitter and how to handle user sessions with Torii. Twitter uses OAuth 1.0a for authentication, which doesn’t require much client-side setup (just the pop-up and the session management). It does however require a significant server-side component for which I will use Sinatra.
