funJSON

• JSON with functions (methods)

Implemented using eval, don't parse untrusted JSON!

Implementation of reviver and replacer functions for JSON parser to stringify, detect and parse methods as strings. Works in browser and node, no dependencies.

Installation

In a browser just load a script:

<script src="https://cdn.jsdelivr.net/npm/funjson/browser/funJSON.min.js"></script>

Using npm:

npm i --save funjson

const funJSON = require('funjson');

or

import { stringify, stringifyToScript, parse } from 'funjson';

Basic Usage

var obj = {
  a:{
    a1:'a1',
    fa:function(name){
      //some comment here
      return 'fa Hello ' + name;
    }
  },
  b:{
    b1:'b1'
  },
  f:(name) => {
    //some comment here
    return 'f Hello ' + name;
  }
};

var str = funJSON.stringify(obj,null,2);// same syntax as for JSON.stringify
console.log('JSON:',str);
var obj2 = funJSON.parse(str);// same syntax as for JSON.parse
obj2.f('obj'); // --> 'f Hello obj'
obj2.a.fa('obj.a'); // --> 'fa Hello obj.a'

str = funJSON.stringifyToScript(obj,null,2);// generate JavaScript string.
//Useful to let user edit it in some code editor.
console.log('JS:',str);
eval('obj2 = '+str);
obj2.f("obj"); // --> 'f Hello obj'
obj2.a.fa("obj.a"); // --> 'fa Hello obj.a'

funJSON.*

• parse(text[,reviver]):object - parses JSON string into object with methods.
  • text - JSON string
  • reviver(key, value) - optional function to customize deserialization.
• stringify(value[, replacer[, space]]):string - serializes object with methods into string.
  • value - object to serialize
  • replacer(key, value) - optional function or array with white list to use instead of default replacer.
  • space - optional, defines how many spaces to use for pretty JSON indentation.
• stringifyToScript(value[, replacer[, space]]):string - serializes object with methods into string script. Functions serialized as is, not wrapped into quots.
  • value - object to serialize
  • replacer(key, value) - optional function to use instead of default replacer.
  • space - optional, defines how many spaces to use for pretty JSON indentation.
