Copy to clipboard React component

Based on [copy-to-clipboard](https://npm.im/copy-to-clipboard)

> Would try to use execCommand with fallback to IE specific clipboardData interface and finally, fallback to simple prompt with proper text content & 'Copy to clipboard: Ctrl+C, Enter'

import {CopyToClipboard} from 'react-copy-to-clipboard';

class App extends React.Component {
  state = {
    value: '',
    copied: false,
  };

  render() {
    return (
      <div>
        <input value={this.state.value}
          onChange={({target: {value}}) => this.setState({value, copied: false})} />

        <CopyToClipboard text={this.state.value}
          onCopy={() => this.setState({copied: true})}>
          <span>Copy to clipboard with span</span>
        </CopyToClipboard>

        <CopyToClipboard text={this.state.value}
          onCopy={() => this.setState({copied: true})}>
          <button>Copy to clipboard with button</button>
        </CopyToClipboard>

        {this.state.copied ? <span style={{color: 'red'}}>Copied.</span> : null}
      </div>
    );
  }
}

const appRoot = document.createElement('div');
document.body.appendChild(appRoot);
ReactDOM.render(<App />, appRoot);
```

## Options


#### `text`: PropTypes.string.isRequired

Text to be copied to clipboard


#### `onCopy`: PropTypes.func

Optional callback, will be called when text is copied

```
onCopy(text, result)
```
`result (bool)`: Returns `true` if copied successfully, else `false`.


#### `options`: PropTypes.shape({debug: bool, message: string})

Optional [copy-to-clipboard](https://npm.im/copy-to-clipboard) options.

See [API docs](https://npm.im/copy-to-clipboard#api) for details

#### `children`: PropTypes.node.isRequired

CopyToClipboard is a simple wrapping component, it does not render any tags, so it requires the only child element to be present, which will be used to capture clicks.

```js
<CopyToClipboard text="Hello!">
  <button>Copy to clipboard</button>
</CopyToClipboard>
```

## Development and testing

yarn install
yarn start

# then
open http://localhost:8080
