# React Native Event Listeners
(This package isn't only restricted to react-native projects. The source is written in plain js with no dependencies to react-native.)

## Why
In some very specific cases it can be charming to have a simple global event listener. While working with global event listeners **you don't have to pass touch events through the component tree** into other components or can **bypass easily the redux architecture** for example.
## Installation
```
npm install --save react-native-event-listeners
```
or
```
yarn add react-native-event-listeners
```
## Usage Example
*Hint: The event listeners also work across different files. You only have to import the ```EventRegister``` in every file you need to send or receive your events.*
```javascript
import { EventRegister } from 'react-native-event-listeners'
/*
* RECEIVER COMPONENT
*/
class Receiver extends PureComponent {
constructor(props) {
super(props)
this.state = {
data: 'no data',
}
}
componentWillMount() {
this.listener = EventRegister.addEventListener('myCustomEvent', (data) => {
this.setState({
data,
})
})
}
componentWillUnmount() {
EventRegister.removeEventListener(this.listener)
}
render() {
return {this.state.data}
}
}
/*
* SENDER COMPONENT
*/
const Sender = (props) => (
{
EventRegister.emit('myCustomEvent', 'it works!!!')
})
>Send Event
)
```
## API
```javascript
// import
import { EventRegister } from 'react-native-event-listeners'
```
