Application Session Management With OAuth -- Ionic & AngularJS

Application Session Management With OAuth

Fun with AngularJS & Ionic

I don't know about other developers -- but one of the most frustrating things in my mind to get going when starting a new hybrid application is session/authorization management. Do you use OAuth 1, OAuth 2, generic email login, facebook...even thinking about it stresses me out. Unfortunately, no good hybrid (or mobile for that matter) application can escape the need for good authorization (unless it is a stateless app, like a calculator, or something easy).

Personally -- I have come to love the OAuth 2 standard for its simplicity, and standards of operation. It takes some of the stress out of the decision making process when coming up with how to manage application state flow -- something which is especially necessary in [most] mobile (or native) applications. This article is going to focus on one of those pain points -- hybrid mobile app state management, and how to solve it with regards to the marriage of AngularJS & Ion
