Single Param Validations

Strictly solo Datatype Validations

Example String ( min and max are allowed )

Example Integer ( min and max are allowed )

Critiq.validate(['integer'], 23554667, function(err,result){})

Example Object ( min and max are forbidden )

Critiq.validate(['object'], {key:'value'}, function(err,result){})

Example Array ( min and max are forbidden )

Critiq.validate(['array'], [1,'two',3,4,'five'], function(err,result){})

Example Function ( min and max are forbidden )

Critiq.validate(['function'], function(){}, function(err,result){})

Multiple Params Validations

// Example String and Number
Critiq.validate(['string','number'], '3456547', function(err,result){})

// Example String and alphaNum
Critiq.validate(['string','alphaNum'], 'aBcd3456547', function(err,result){})

// Example String and Number
Critiq.validate(['string','alphaber'], 'abcdEfgHij', function(err,result){})

Catch the Error and Result

Critiq.validate(['string'], 'asdfasdf', function(err,result){

    if(err){
      console.log(err);
      return
    }
    console.log('Hooray data is valid!')
    console.log(result)

  })

Complex Validation

PARAMETERS

• config - (Object) containing the fields you want to validate from the data
• data - (Object) data set
• callback - (function) callback is call after validation process is done.

  Callback Parameters

  • error - null if no error
  • result - null if has error

Below is an example

var payload = {

  email:'[email protected]',
  username:'user123',
  accountNumber: 1478248799308456,
  callback:function(){},
  education:{
    highschool:'name of highschool',
    college:'name of college school',
    awards:{
      award1:'Award1 name',
      award2:'Award2 name',
      award3:'Award3 name',
    }
  },
  friends:['tina','james']


}

var config = {

  email:['string','email','required'],
  username:['string','alphaNum','min-5','max-15'],
  accountNumber: ['integer','min-10','max-16'],
  callback: ['function'],
  education: ['object', {
    highschool: ['string','min-500'], // has error for testing
    college: ['string','min-5'],
    awards:['object',{
      award1:['number'] //has error for testing
    }]
  }],
  friends: ['array']

}

Critiq.validate(config, payload, function(err,result){

  if(err){
    console.log(err);
