NexaAddr.js: The Nexa address format for Node.js and web browsers.

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")
}

Browser

Script Tag

You may include a script tag in your HTML and the cashaddr module will be defined globally on subsequent scripts.

<html>
  <head>
    ...
    <script src="https://unpkg.com/nexaaddrjs@1.1.1/dist/nexaaddrjs-1.1.1.min.js"></script>
