json-fns

About

json-fns is a JSON parser/stringifier that supports functions and regexp.

json-fns uses the native JSON parse and stringify methods and extends them to support functions and regular expressions.

Install

npm i json-fns

Usage

Node

Stringify

const JSONfns = require('json-fns')
 
const obj = {
    someFn: function (x) { console.log(x) },
    someRegexp: /foobar/
}
 
JSONfns.stringify(obj);

Note: objects serialized by JSONfns.stringify can only be restored back completely with JSONfns.parse. Using JSON.parse, although it works, will result in incomplete/incorrect objects.

Parse

const JSONfns = require('json-fns')
 
const serializedObj = '{ "someFn": "function (x) { console.log(x) }" }'
 
JSONfns.parse(serializedObj)

Browser

Just include it in your html:

<script type="text/javascript" src="https://unpkg.com/json-fns/json-fns.js">

The JSONfns object will be available in your global scope.

AMD is also supported.

API

• JSONfns.serialize(obj, space)

  • obj: the object to serialize in JSON format
  • space(optional) a String or Number object that's used to insert white space into the output JSON string for readability purposes. This is the exact same parameter passed to JSON.stringify (more info)

• JSONfns.parse(str)

  • str: the serialized object in string format

Credits

json-fns is an improved fork of json-fn that seems to be abandoned for some time.
