Devise[1] alone makes it worth using rails for many webapps. Throw in things like simple form[2] and will paginate[3] and it's incredible how much you can get done cleanly and quickly. Using something like intercooler.js, you can build a solid modern web app in a fraction of the complexity of most systems today.
That's interesting! I do some ajax with the js.erb files, but I honestly find that it's pretty messy & gross. Maybe I could eliminate those .js.erb files with intercooler.js (or clean them up).
Do you find that intercooler lets you avoid using .js.erb files altogether?
