A few nights ago, I started up a new project called extstack. Instead of designing a registration and authentication system, I will rely on the nodejs module, everyauth. Everyauth authenticates with many different popular social sites: twitter, facebook, github, etc.
This new project will have exactly the same requirements and goals as portalstack, but with a more useful name and a little more care in the architectural design of the stack.
I investigated Express and its template abilities, such as jade. I have since learned jade works well with everyauth, eliminating redundant lines of code and simplifying the HTML UI aspect of the stack.
