Folder structure for both server side and thick client web app

Question

Currently I am using Node.js for the backend and either extjs or backbone for the client and I am now completely confused on the folder structure.

Using express my folder structure is as follow

appname
  |--controllers
  |--models
  |  |--appmodel.js
  |--public
  |  |--css
  |  |--js // any client-side javascripts
  |--routes
  |  |--router.js
  |--views
  |  |--appview.ejs
  |--app.js

where app.js is the point of entry and it uses router.js to handle routing and rendering of the views. This works fine if it is only server-side development. Now if I want to use ExtJS or Backbone for the client, how should I organize my code? Should I add it to public folder or views?

appname
  |--controllers
  |  |--extbasedcontroller.js // correct location?
  |--models
  |  |--appmodel.js
  |  |--extbasedmodels.js // correct location?
  |--public
  |  |--css
  |  |--js
  |  |  |--extjs // extjs files
  |--routes
  |  |--router.js
  |--views
  |  |--appview.ejs
  |  |--extbasedview.ejs // correct location?
  |--app.js

If this is the case, where should I put the model for my extjs files? If I put it in models folder it feels like I'm mixing up client and server code in one folder and it's going to be confusing...

Answer 1

Just put the whole /webapp under /public so you'll end creating, for instance, frontend's models under /public/webapp/models

appname
  |--models
  |  |--appmodel.js
  |--public
  |  |  |--webapp // extjs/backbone files
  |  |  |  |--models
  |  |  |  |--controllers
  |  |  |  |--css
  |  |  |  |--js
  |  |  |  |--img
  |  |  |  |--views
  |  |  |  |  |--appview.ejs
  |  |  |  |  |--extbasedview.ejs
  |--routes
  |  |--router.js
  |--app.js

In your place, I would do that way:

appname
  |--ServerCode
  |  |--controllers
  |  |--models
  |  |  |--appmodel.js
  |  |--routes
  |  |  |--router.js
  |  |--views
  |  |  |--appview.ejs
  |  |--app.js
  |--public
  |  |--css
  |  |--js // any client-side javascripts
  |  |--models
  |  |--controllers
  |  |--...

The main idea is to place public folder outside of the scope of your server javascript files.
