Absolutecore Library

A pure and powerful JavaScript Absolute library.

Absolute is a powerful new peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Dash network allows for highly resilient Absolute infrastructure, and the developer community needs reliable, open-source tools to implement Absolute apps and services.

Browser

CDN Standalone

<script src="https://unpkg.com/@dashevo/absolutecore-lib"></script>

const { PrivateKey } = dashcore;
const privateKey = new PrivateKey();
const address = privateKey.toAddress().toString();
...
</script>

Building the Browser Bundle

To build a absolutecore-lib full bundle for the browser:

npm run build

This will generate a file named dashcore-lib.min.js in the dist/ folder.

Usage

Browser

<script src='./dist/absolutecore-lib.min.js' type="text/javascript"></script>
<script>
  const PrivateKey = dashcore.PrivateKey;
  const privateKey = new PrivateKey();
  const address = privateKey.toAddress().toString();
</script>

Modules

Some functionality is implemented as a module that can be installed separately:

• Payment Protocol Support
• Peer to Peer Networking
• Dash Core JSON-RPC
• Mnemonics
• Elliptical Curve Integrated Encryption Scheme
• Signed Messages

Development & Tests

git clone https://github.com/absolute-community/absolutecore-lib
cd absolutecore-lib
