js-jsonf

JS Objects w/ function support.

Move JS from one live system to another.

engines: node >= 8.x

Example

const {encode, decode} = require('js-jsonf');
const obj = {
  a: 1,
  b() {
    return 1;
  }
};
const str = encode(obj);
const obj1 = decode(str);

Installation

npm i js-jsonf --save

API

.encode(obj, [throwOnInvalidType = false])

Returns false given an invalid type.

.decode(str, [throwOnInvalidSyntax = false])

Returns undefined given a invalid syntax.

Supported data types

• String
• Boolean
• Number
• Array
• Object
• Date
• Function (all combinations of: regular, async, generator, arrow)
• NaN
• null
• undefined

All types are supported when wrapped in a function.

Caveats

Function behavior is normalized and consistent; however, the parsed function may contain slight formatting differences from the original; its functionality however, will remain consistent.

Perf

As fast as native JSON.parse() JSON.stringify():

// 1M iterations. Each iteration calls both encode and decode.

// js-jsonf:
