Package Exports

json-future

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-future) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

JSON Future

Last version

Unbelievable and Modern JSON interface. Prollyfills propositions for ECMAScript 7.

Prollyfill: A polyfill for a not yet standardized API.

Why

High level methods for manipulate JSON files (stringify, parse, load and save).
Backward compatibility with JSON Object in Node or Browser.
Async support (Node Callback style and Promise).

JSON Future is based into a set of cool libraries to handle JSON, but some of this libraries uses promises or callback style. This library adds an extra layer to call these libraries uniformly.

Install

npm install json-future --save

If you want to use in the browser (powered by Browserify):

bower install json-future --save

and later link in your HTML:

<script src="bower_components/json-future/dist/json-future.js"></script>

Usage

var jsonFuture = require('json-future');

Don't be afraid to replace for the default JSON object. The library is specially designed for be compatible and don't break your code:

JSON = require('json-future');

Also you can do this action using the register helper:

require('json-future/register')
