JS Stellar Base

The stellar-base library is the lowest-level stellar helper library. It consists of classes to read, write, hash, and sign the xdr structures that are used in stellar-core. This is an implementation in JavaScript that can be used on either Node.js or web browsers.

• API Reference

Warning! Node version of this package is using ed25519 package, a native implementation of Ed25519 in Node.js, as an optional dependency. This means that if for any reason installation of this package fails, stellar-base will fallback to the much slower implementation contained in tweetnacl.

If you are using stellar-base in a browser you can ignore this. However, for production backend deployments you should definitely be using ed25519. If ed25519 is successfully installed and working StellarBase.FastSigning variable will be equal true. Otherwise it will be false.

Quick start

Using npm to include js-stellar-base in your own project:

npm install --save stellar-base

For browsers, use Bower to install it. It exports a variable StellarBase. The example below assumes you have stellar-base.js relative to your html file.

<script src="stellar-base.js"></script>
<script>console.log(StellarBase);</script>

Install

To use as a module in a Node.js project

1. Install it using npm:

npm install --save stellar-base

2. require/import it in your JavaScript:

var StellarBase = require('stellar-base');

To self host for use in the browser

1. Install it using bower:

bower install stellar-base

2. Include it in the browser:

<script src="./bower_components/stellar-base/stellar-base.js"></script>
<script>console.log(StellarBase);</script>

If you don't want to use install Bower, you can copy built JS files from the bower-js-stellar-base repo.

To use the cdnjs hosted script in the browser

1. Instruct the browser to fetch the library from cdnjs, a 3rd party service that hosts js libraries:

<script src="https://cdnjs.cloudflare.com/ajax/libs/stellar-base/{version}/stellar-base.js"></script>
<script>console.log(StellarBase);</script>

Note that this method relies using a third party to host the JS library. This may not be entirely secure.

Make sure that you are using the latest version number. They can be found on the releases page in Github.

To develop and test js-stellar-base itself

1. Clone the repo

git clone https://github.com/stellar/js-stellar-base.git

2. Install dependencies inside js-stellar-base folder

cd js-stellar-base
npm install
