Build Status

Validity style validator which validates a field against a set of valid options

Installation

npm install validity-required-options

Usage

Below is a simple example for usage with schemata:


var validity = require('validity')
  , schemata = require('schemata')
  , save = require('save')
  , createValidator = require('validity-required-options')

var schema = schemata(
    { state:
      { type: String
      , validators: { all: [ createValidator([ 'option1', 'option2' ]) ] }
      }
    })

API

var validate = createValidator()

Create a validate function.

validate(String:key, String:keyDisplayName, Object:object, Function:cb)

This is a validity compatible function, which in turn is used by schemata for schema validation.

The callback signature cb(err, errorMessage).

err is an Error object if something bad happened and null otherwise. errorMessage is a String if a validation error happened and undefined otherwise.
