See more scripts in the package.json file or the makefile.

There is a peer dependency on the bsv library. This version of the JS BUX client supports version 1.x of the bsv library.


Here's the getting started with BUX

import bsv from 'bsv';
import { BuxClient } from 'js-buxclient';

const server = "http://localhost:3003/v1";
const transportType = 'http'; // or graphql
const xPriv = bsv.HDPrivateKey.fromRandom();

const buxClient = new BuxClient(server, {
  signRequest: true,

const recipients = [{
  to: "test@handcash.io",
  satoshis: 10000,
const result = await buxClient.SendToRecipients(recipients, { agent: 'Bux test' })

Connection as a BUX admin

You can add the admin key to the BUX client after initialisation to support admin requests (IE: registering an xPub).

const adminKey = 'xprv.....';

Library Deployment

Releases are automatically created when you create a new git tag!

If you want to manually make releases, please install GoReleaser:

goreleaser for easy binary or library deployment to Github and can be installed:

  • using make: make install-releaser
  • using brew: brew install goreleaser

The .goreleaser.yml file is used to configure goreleaser.

Automatic Releases on Tag Creation (recommended)

Automatic releases via Github Actions from creating a new tag:

make tag version=1.2.3

Manual Releases (optional)

Use make release-snap to create a snapshot version of the release, and finally make release to ship to production (manually).
