revalidator

revalidator

A cross-browser / node.js validator used by resourceful and flatiron.

Example

The core of revalidator is simple and succinct: revalidator.validate(obj, schema):

  var revalidator = require('revalidator');
  
  console.dir(revalidator.validate(someObject, {
    properties: {
      url: {
        description: 'the url the object should be stored at',
        type: 'string',
        pattern: '^/[^#%&*{}\\:<>?\/+]+$',
        required: true
      },
      challenge: {
        description: 'a means of protecting data (insufficient for production, used as example)',
        type: 'string',
        minLength: 5
      },
      body: {
        description: 'what to store at the url',
        type: 'any',
        default: null
      }
    }
  }));

This will return with a value indicating if the obj conforms to the schema. If it does not, a descriptive object will be returned containing the errors encountered with validation.

  {
    valid: true // or false
    errors: [/* Array of errors if valid is false */]
  }

In the browser, the validation function is exposed on window.validate by simply including revalidator.js.
