A nice set of tutorials on how to get a rest service up and running in nodejs with authentication.
What is also good is that it is using Express 4, if your currently wanting to migrate from 3 and your having trouble this could be a useful tutorial in order to get a solution working.
With an ever growing collection of beer, I am in dire need of a way to store and track my beer. What better way to do this than to create an application where I can add, remove, update, and view my beer collection. Like any motivated developer, I want my friends to be able to create their own lockers and control who has access to mine. In this multipart series we’ll be creating a RESTful API using Node, Express, Mongoose to interact with MongoDB, Passport for authentication, OAuth2orize for OAuth support, and explore best practices and tools.
