K-Validation

Introduction

Validation library inspired from joi library and laravel validator, to make easy validation in vanilla.js

Code Samples

basic usage:

var validator = KValidation.schema(rules).validate(value)

or can be used with a callback

KValidation.schema(rules).validate(value, function(result) {
	// return
})

return from function was object with 3 keys applied

1. status [HTTP STATUS CODE] sign the function execution
2. message [STRING] show message according to status
3. data [OBJECT|NULL] return null if there was no errors validation

pass rules object to schema function. example:

{
   "id": "required",
   "title": "required|min-6"
}

KValidation have built-in validation rules:

• string
• number
• required
• min-{value} // min-6
• max-{value} // max-12
• phone
• email
• RegExp // regex-(/[^0-9]/g) see notes for detail
• sameas-{id} // sameas-id

Notes

• for using regex rules, you must escape some special characters because rules writed as string for example regex-(/\d/g) will return regex-(/d/g) if you not escape the special characters, so you had changes like this regex(/\\d/g) and it will return regex-(/\d/g)

Validation values can be passed with two variant

{
   "id": "{value}"
}

or advanced using

{
   "id": {
       "value": "value",
       "field": "field name",
       "rules": {
         "required": "custom message"
       }
   }
}

explanation:

value: Value want validate

field: Re-assign return field name if you called in custom message

rules: Object with keys have a same name with validation rules

notes: to call field name in custom message, follow example below

{
	"id": {
	  "value": "value",
	  "field": "User ID", // if you not passing it with default use object key as field name
	  "rules": {
		"required": "field {{field}} can't be empty!" // will return field User ID can't be empty!
	  }
	}
}

Installation

The installation instructions are low priority in the readme and should come at the bottom. The first part answers all their objections and now that they want to use it, show them how.
