## README

# Ducatuscore JavaScript Library for Ducatuscore

**A pure and powerful JavaScript library for Ducatuscore.**

## Principles

Ducatuscore is a powerful new peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Ducatuscore network allows for highly resilient ducatuscore infrastructure, and the developer community needs reliable, open-source tools to implement ducatuscore apps and services. Ducatuscore JavaScript Library provides a reliable API for JavaScript apps that need to interface with Ducatuscore.

## Get Started

Clone the Ducatuscore monorepo and `npm install`:

## Building the Browser Bundle


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

```sh
gulp browser
```

This will generate files named `ducatuscore-lib.js` and `ducatuscore-lib.min.js`.

## Running Tests

```sh
npm test
```

You can also run just the Node.js tests with `gulp test:node`, just the browser tests with `gulp test:browser` or create a test coverage report (you can open `coverage/lcov-report/index.html` to visualize it) with `gulp coverage`.
