Questions tagged [chicagoboss]

Chicago Boss is a server framework inspired by Rails and written in Erlang.

Chicago Boss takes advantage of functional programming and under-the-hood compiler magic to provide clean, understandable controller logic, Django-style templates, and an ORM based on Erlang's parameterized modules. The best part is that the network I/O is 100% asynchronous so you can seamlessly integrate Comet endpoints into your app, and you never have to worry about a slow database query dragging down unrelated requests.
