A simple example of makesure using CoffeeScript

makesure.example.coffee

validateUser = makesure ->
  @permit "name email" # optional
  @attrs("name email").isNot('empty').orSay "can't be empty"

userInput =
  name: ""
  description: "My description"
  admin: true
 
 
# Validates a object, with an intrusive attribute.
validateUser userInput, (error, user) ->
 
 
# error == {
#   error: {
#     attrs: {
#       name: {
#         messages: { "empty": "can't be empty" }
#       }
#     }
#   }
# }
# user == {
#   name: '',
#   description: 'My description'
# }

The parentesis in makesure are optionals 😆

validateUser = makesure ->
  @permit "name email" # optional
  @attrs("name email").isNot(empty).orSay "can't be empty"

🆒 🎱 !! 😄 good catch @dgmike!
