Cozy: a Database-less RESTful Layer

After exploring some static site recipes in my staticRack project, I wanted to explore the world of simple, static Content Management Systems. There is a PHP implementation of that sort of idea in Pulse CMS, and Ruby has something a bit different called Nesta. The latter, in particular, is a great solution
if you love managing static sites with a desktop text editor and want a simple way to customize or build completely new designs. I decided to explore a custom CMS based on Sinatra to learn building apps with Rack and Sinatra.

The idea was to have a general-purpose layer that can be easily deployed using pretty much any web server and that allows flexible management and development of content. Imagine a RESTful API that abstracts away the messy local filesystem and lets you create objects that are stored as static files. If you're working
on a simple JavaScript client and want local filesystem access, such a layer would be immensely helpful. There is also some separation of concerns between the client and server and the whole thing starts looking like a general mini-framework
that can be used to target a wide range of problems. Also, after initial deployment, such a project could allow continued development through a REST client on any browser or even mobile device. And with the possibility of standalone deployment
with Passenger
and even simpler deployment with Heroku, such a project can actually have widespread, general use.

I worked out some initial functionality and pushed it here. I'm calling it Cozy, and hopefully it evolves into a good way to make basic prototypes, to have database-less dynamic web apps, or to manage static websites. For now, Cozy can create, read, update, and delete "nodes," which can be any kind of
file. There is also some authentication to protect the create, update, and delete actions. The code is a little brittle right now, but you get the idea.

While the true capabilities and drawbacks are not clear yet, this idea of a static REST backend is turning out to be a great educational project. If anything, it can help inform a future attempt to create a light framework. In the meantime,
I'm absolutely loving Sinatra's simplicity and will have some followups exploring the specifics of Cozy.
