## Install

### NodeJS

```
npm install @gohelpfund/helpcore-lib
```

### Browser

See the section below to generate your own bundle, or download the pre-generated [minified file](dist/helpcore-lib.min.js)

#### Building the Browser Bundle

To build a helpcore-lib full bundle for the browser:

```sh
npm run build
```

This will generate files named `helpcore-lib.js` and `helpcore-lib.min.js` in the `dist/` folder.

## Usage

### Browser

```
<script src='./dist/helpcore-lib.min.js' type="text/javascript"></script>
<script>
  const PrivateKey = helpcore.PrivateKey;
  const privateKey = new PrivateKey();
  const address = privateKey.toAddress().toString();
</script>
```
