> A pure and powerful JavaScript Gewel library.

## Install

### NodeJS

```
npm install @gewelio/gewelcore-lib
```

### Browser

See the section below to generate your own bundle, or download the pre-generated [minified file](dist/gewelcore-lib.min.js)

#### Building the Browser Bundle

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

```sh
npm run build
```

This will generate files named `gewelcore-lib.js` and `gewelcore-lib.min.js` in the `dist/` folder.

## Usage

### Browser

```
<script src="./dist/gewelcore-lib.min.js" type="text/javascript"></script>
<script>
  const PrivateKey = gewelcore.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](https://github.com/gewelio/gewelcore-payment-protocol)-->
* [Peer to Peer Networking](https://github.com/gewelio/gewelcore-p2p)
* [Gewel Core JSON-RPC](https://github.com/gewelio/geweld-rpc)
<!--* [Payment Channels](https://github.com/gewelio/gewelcore-channel)
* [Mnemonics](https://github.com/gewelio/gewelcore-mnemonic)
* [Elliptical Curve Integrated Encryption Scheme](https://github.com/gewelio/gewelcore-ecies)
* [Signed Messages](https://github.com/gewelio/gewelcore-message)-->

### Development & Tests

```sh
git clone https://github.com/gewelio/gewelcore-lib
cd gewelcore-lib
npm install
```
