@woop-js/utils
This package provides a collection of utility apis for unit conversions like fromWei, toWei, hexToNumber, numberToHex, isAddress, etc.
Installation
npm install @woop-js/utils
Usage
Available units
const { Units } = require('@woop-js/utils');
[Units.wei, '1'], // 1 wei
[Units.Kwei, '1000'], // 1e3 wei
[Units.Mwei, '1000000'], // 1e6 wei
[Units.Gwei, '1000000000'], // 1e9 wei
[Units.szabo, '1000000000000'], // 1e12 wei
[Units.finney, '1000000000000000'], // 1e15 wei
[Units.ether, '1000000000000000000'], // 1e18 wei
[Units.one, '1000000000000000000'], // 1e18 wei
[Units.Kether, '1000000000000000000000'], // 1e21 wei
[Units.Mether, '1000000000000000000000000'], // 1e24 wei
[Units.Gether, '1000000000000000000000000000'], // 1e27 wei
[Units.Tether, '1000000000000000000000000000000'], // 1e30 wei
Converting between different units
const { Units, Unit, numberToString, add0xToString, fromWei, toWei, numToStr} = require('@woop-js/utils');
const { BN } = require('@woop-js/crypto');
const one = new Unit('1').asOne();
const oneToGwei = one.toGwei();
console.log(oneToGwei);
// numberToString
const num = 123;
const str = numberToString(num)
console.log(str);
// add0xToString
const str = '12345';
const expected = add0xToString(str)
console.log(expected);
// fromWei
const Wei = new BN('1000000000000000000');
const expected = fromWei(Wei, Units.one);
console.log(expected);
// toWei
const one = new BN('1');
const expected = toWei(one, wiki.utils.Units.one);
const num = numToStr(expected);
console.log(num);
