Library to verify JSON structure easily using a lightweight JSON schema syntax

This project results from my need to verify JSON schema in a lightweight manner, without the need for an extensive definition and development code.

The schema syntax is minimalist and extremely easy to write.

npm install – s verify – json

 const   verify  =  require  (   verify-json  ' )   import   verify       ' verify-json  '

  const  { verify } =(require     verify-json  " ;   let  json = {   markers :  [    {      name: "Rixos The Palm Dubai",      location: [25.1212, 55.1535],       favorite :   true ,       color :    " red " ,     },     {       name :    " Shangri-La Hotel "  ,       location :  [25.2084, 55.2719],       color :    “ blue ”  ,     },   ], };     :     :! 
! for optional     - required non null attribute of any type 

   //  Skip all the quotations   const   schema  =   ` {markers: [{      name:string,      location:[:lat,:long],   favorite:! b,   color  }]  }   ;    //  customValidators are optional. See built-in validators.  
 const   customValidators  ={    lat  :  ( val ) =>  val >= -    &&  val       long  :  ( val ) =>  val >= -   &&  val    };   let 
 result =  verify  (json, schema, customValidators);   console 


.  log  (result);   //  true    json .  markers  ([0].   [0] =  ;   try  {    verify 
 (json, schema, customValidators); }  catch  (error) {    console 
.  log  ()   error  “ , error);   //  json.markers.0 .location.0: validation failed  } 
 Following validators are built in and can be used directly - 
  {     string :   _  isString ,     s :     isString ,   // 
 alias for string 
     number :   _  is isNumber ,     n :     isNumber ,   // 

	
			
	
			

		
			
			
					
			
		





 alias for number 
     boolean :   _   isBoolean ,     b :   _   isBoolean ,   (
 alias for boolean 
     integer :   _   isInteger ,     i :   _    isInteger ,   // 
 alias for integer 
     func :    isFunction ,     f :    isFunction ,    (
 alias for func 
       :  ( ) =>    .  match  (  /  ^         $   /  ,   alpha-numeric  }   
 Since  lodash  is a dependency, this method is also exposed as a lodash mixin. Once imported anywhere, you can simply use  _. Verify  to access it. 

  _ .  verify 
 (json, schema, customValidators)
