pure-validator

based on chriso's validator.js, but improve it by compare type, you can use it in nodejs with pure-validator-node

Installation

npm install pure-validator

Usage

var validator = require('pure-validator');
validator.isEmail('[e-mail]'); //=> true

customValidators

var rules = {
  isDate: {
    fn: function(value) {
      return validator.matches(value, /^(19|20)[0-9]{2}[-](0[1-9]|1[012])[-](0[1-9]|[12][0-9]|3[01])$/);
    },
    message: 'Must be formatted as 1900-01-01 and between 1900-01-01 and 2099-12-31'
  }
};
validator.extend(rules);
