Validators which can be shared between browsers and Node.js_, based onDjango_'s core validators.
Validators are Functions which take a value and throw a `ValidationError if
they detect that it is invalid.
Browsers:
* validators.js_ / validators.min.js_
Node.js::
npm install validators
.. _Node.js: http://nodejs.org/Django
.. _: https://www.djangoproject.com/validators.js

Error
=====
ValidationError(messages[, {code: null, params: null}])
-----------------------------------------------------------
Validation error constructor.
For customisation purposes, in addition to a validation message, aValidationError may specify a code to itentify the category of error and
any params which were inserted into the validation message, when applicable.
For messages, you can pass:
* a single message as a String
* a list of messages
* an object containing field-specific messages, with properties corresponding to
field names.
Utilities
=========
EMPTY_VALUES
----------------
Defines input values for which a field is considered to be empty. These are:
* null
* undefined
* ''
Validators
==========
RegexValidator(options)
---------------------------
Creates a validator which validates that input matches a regular expression.
Options which can be passed are:
* regex -- the regular expression pattern to search for the provided value,
or a pre-compiled RegExp. By default, matches any string (including an
empty string)
* message -- the error message used by ValidationError if validation
fails. Defaults to "Enter a valid value".
* code -- the error code used by ValidationError if validation fails.
Defaults to "invalid".
* inverseMatch -- the match mode for regex. Defaults to false.
URLValidator(options)
-------------------------
Creates a validator which validates that input looks like a valid URL.
Options which can be passed are:
* schemes -- allowed URL schemes. Defaults to
['http', 'https', 'ftp', 'ftps'].
EmailValidator(options)
---------------------------
Creates a validator which validates that input looks like a valid e-mail
address.
Options which can be passed are:
* message -- error message to be used in any generated ValidationError.
* code -- error code to be used in any generated ValidationError.
* whitelist -- a whitelist of domains which are allowed to be the only thing
to the right of the @ in a valid email address -- defaults to
['localhost'].
validateEmail(value)
------------------------
Validates that input looks like a valid e-mail address -- this is a
preconfigured instance of an EmailValidator,
validateSlug(value)
-----------------------
Validates that input is a valid slug.
validateIPv4Address(value)
------------------------------
Validates that input is a valid IPv4 address.
validateIPv6Address(value)
------------------------------
Validates that input is a valid IPv6 address.
validateIPv46Address(value)
------------------------------
Validates that input is a valid IPv4 or IPv6 address.
ipAddressValidators(protocol[, unpackIPv4])
-----------------------------------------------
Returns the appropriate validator for validating IPv4 or IPv6 addresses, passing'ipv4', 'ipv6', or 'both' as protocol.
If a truthy unpackIPv4 argument is given and protocol is not 'both',
an Error will be thrown.
validateCommaSeparatedIntegerList(value)
--------------------------------------------
Validates that input is a comma-separated list of integers.
BaseValidator(limitValue)
-----------------------------
Base constructor for validators which compare input against a given value.
MaxValueValidator(limitValue)
---------------------------------
Validates that input is less than or equal to a given value.
MinValueValidator(limitValue)
---------------------------------
Validates that input is greater than or equal to a given value.
MaxLengthValidator(limitValue)
----------------------------------
Validates that input is at least a given length.
MinLengthValidator(limitValue)
----------------------------------
Validates that input is at most a given length.
Additional IPv6 Functions
=========================
ipv6.isValidIPv6Address(value)
------------------------------------
Returns true if input is a valid IPv6 address, false otherwise.
ipv6.cleanIPv6Address(value[, {errorMessage: '...', unpackIPv4: false}])
----------------------------------------------------------------------------
Cleans an IPv6 address string -- replaces the longest continious zero-sequence
with '::' and removes leading zeroes and makes sure all hextets are lowercase.
If an invalid address is passed, a ValidationError` is thrown.
