[erlang-questions] Code organization for virtual websites based on Cowboy

[Loïc Hoguin]

Hi,

Sorry for the late reply, I had to think a little about it.

I would have a single application for all handlers.

I would create two folders under src, one per host. For example:

  src/www
  src/chat

Static files I would probably want to have a specific host for them so I 
wouldn't need to separate (I could create extra folders for the 
host-specific stuff, but there's no reason to separate jquery and others).

On initialization I would have the file src/my_app.erl call a predefined 
function for each host to get their routing rules, for example 
www_routes:get() ++ chat_routes:get().

I would make sure that I only have handlers or helpers in this 
application. I would make separate applications for different parts of 
the system, for example an application for managing sessions, an 
application for chat communication, an application for www business 
logic, etc. and I would call these applications from the handlers.

Does this answer your question?
