Easy AngularJS Authentication with Auth0
May 11, 2017 for SitePoint
Authentication for single page apps can be a tricky matter. In many cases, SPA architecture involves having an isolated front-end application with a framework like AngularJS, and a separate backend that serves as a data API to feed the front-end. In these cases, traditional session-based authentication that is done in most round-trip applications falls short. Session-based authentication has a lot of issues for this kind of architecture, but probably the biggest is that it introduces state to the API, and one of the tenets of REST is that things remains stateless. Another consideration is that if you ever want to use that same data API as a backend for a mobile application, session-based authentication won’t work.
