bignumberify

bigNumberify

A simple parser to correctly rebuild objects containing big numbers while parsing JSON strings

Intro

Managing transactions and results of query to smart contracts, you get a JSON string that encodes some Big Number in a format like

{
  "bn": {
    "type": "BigNumber",
    "hex": "0x32"
  }
}

If you JSON.parse it, the property bn won't be a BigNumber :(

bigNumberify fixes the issue fixing all the BigNumber objects inside the JSON.

Usage

In a Node app load as

const bigNumberify = require("bignumberify");

In a ES6 app, load as

import {bigNumberify} from "bignumberify";

To parse an object

const obj = bigNumberify(inputObj);

or as a reviver function

const obj = JSON.parse(jsonStr, bigNumberify);
