pipeline status coverage report

NPM

JavaScript implementation for the Nexa cryptocurrency address format.

Compliant with the Nexa address specification.

Installation

Using NPM

$ npm install --save nexaaddrjs

Using Bower

$ bower install --save nexaaddrjs

Manually

You may also download the distribution file manually and place it within your third-party scripts directory: dist/nexaaddrjs-1.1.1.min.js.

Usage

In Node.js

const nexaaddr = require('nexaaddrjs');
const address = 'nexatest:qzmzm493h5j67z2zk2lsag4qeye02x5pxyrlswqv76';
const { prefix, type, hash } = nexaaddr.decode(address);
console.log(prefix); // 'nexatest'
console.log(type); // 'P2PKH'
console.log(hash); // Uint8Array [... ]
console.log(nexaaddr.encode(prefix, type, hash)); // 'nexatest:qzmzm493h5j67z2zk2lsag4qeye02x5pxyrlswqv76'

Example with bitcore-lib

This example decodes a Nexa cashaddr P2PKH address and loads it into a bitcore-lib Address. Even though bitcore-lib is for Bitcoin, Nexa P2PKH is equivalent to Bitcoin/Bitcoin Cash P2PKH so some bitcore-lib operations apply.

var bitcore = require("bitcore-lib");
var nexaaddr = require("nexaaddrjs");

const fixAddressFormat = address => {
    let addrBytes = nexaaddr.decode(address);
    let buf = addrBytes.hash.buffer.slice(1,21);  // ignore the type byte
    let buf2 = Buffer.from(buf);
    console.log(buf);
    console.log(buf2);
    return bitcore.Address.fromPublicKeyHash(buf2, "livenet")
}
