Vim Underground is a couchapp, that is, a web application served from CouchDB itself. While most of the application makes use of CouchDB’s awesome features, it uses node.js and ruby sparingly to overcome certain limitations of CouchDB and to speed up development.
CouchDB displays most of the data for the site through several views and lists. Templates, inside the templates directory, provide the underlying HTML. The lib directory contains modules that one can use inside of lists, shows, views, and updates. Speaking of which, the db folder houses those functions, along with filters that the app consumes to notify of new articles and to keep up to date with the latest script activity from the vim-scripts atom feed.
VU uses soca for pushing changes to CouchDB. Additionally, seeding the database requires thor, along with compass for the look and feel of the site. See the Gemfile for other ruby dependencies.
The Jimfile lists all JavaScript dependencies. Rather than letting soca concatenate all our scripts into one big file, VU uses yepnope.js instead to load them asynchronously. Scripts are divided into three sections: core, plugins, and application. Core includes all mandatory scripts, such as Sammy.js and jquery.couch. Plugins includes scripts like sammy.mustache and h5validate. Lastly, application contains helpers, models and app.js.
VU uses CouchDB external processes for things like sending emails and new article submission notifications. In addition, there’s a screen scraper script in data/tasks for scraping vim plugin information from the vim site.
VU is a subscriber to the vim-scripts atom feed. To subscribe, follow the instructions here. Make sure to specify the callback as http://yourapp.com/feeds/feed-name.
