Validity

A validation framework for JavaScript models.

Features

• Wide variety of built in validators.
• Integrates easily with server side validation (i.e rails, node)
• Supports class-specific validations.
• Easy to add new site-wide validators, via the Validity.RULES dictionary.
• Works great with jQuery and Angular.js

Example

# Define a class with some validation rules
class Person
  Validity.define @,
    name: 'required'
    email: {regex: /.+\@.+\..+/}
    age: ['number', {greaterThan: 0}]
    zipcode: ['required', {length: 5}]

person = new Person
person.isValid() #= false
person.errors #= {name: ["can't be blank"], age: ["must be a number", "must be greater than 0"], zipcode: ["can't be blank", "must have exactly 5 characters"]}

person.name = 'John Smith'
person.age = 47
person.zipcode = '12345'
person.isValid() #= true
person.errors #= {}
