using coffeescript on windows

If you want to develop with CoffeeScript outside of Rails, here’s one way you could do it:

  • download the coffee.exe executable from CoffeeScript compiler for Windows
  • copy coffee.exe in a folder that is on the PATH
  • create a watchr file, for the ruby gem watchr. This way, everytime you modify the .coffee file, the js file gets recompiled. Here are the contents of my watchr file:
    watch("js/") do |s|
    	puts "#{} => Compiling #{s}"
    	system("coffee -c #{s[0]}")
  • start watching the file for modifications:
    watcher your_watch_file.rb
  • add the include for the resulting JS in your html code and you’re done
