AngularJS is an awesome javascript framework. With it’s $resource service it is super fast and easy to connect your javascript client to a RESTful API. It comes with some good defaults to create a CRUD interface.

However if you are using an API, which needs authentication via an auth token, you might run into issues: The resource factory creates a singleton. If you do not already have an auth token when the factory is called, or if the auth token changes afterwards, you cannot put the auth token as a default request parameter in the factory.

This article shows, how to solve this. First we define our resource, consuming a RESTful API, without using an authentication. Afterwards we create a wrapper to send the auth token with every request. This allows consumption of an API with an exchangeable auth token.
