# react-native-display

This module brings "Display: none" (css style) to turn on/off components from render. Using this module will improve your app performance and appearance with the enter/exit animations.



![intro](https://cloud.githubusercontent.com/assets/9949238/22396351/f1452940-e55f-11e6-8e9b-ae26396c2051.gif)



## Installation



`$ npm install react-native-display --save`



## Dependencies

[`react-native-animatable`](https://github.com/oblador/react-native-animatable)



## Usage

```js

import Display from 'react-native-display';

```

### Then, easy as:

```js



   My custom components 



```



## Properties

#### ***`enter/exit`***  props using [react-native-animatable](https://github.com/oblador/react-native-animatable) for animation name.

| Prop | Description | Default |

|---|---|---|

|**`enable`**|`true` to render. `false` to not render. |`true`|

|**`defaultDuration`**|Default duration for enter and exit animations. |`250`|

|**`enterDuration`**|Duration for enter animation. |`250`|

|**`exitDuration`**|Duration for exit animation. |`250`|

|**`enter`**|Animation name to run when render (***enable=true***).
Example: ***enter='fadeIn'*** |None|

|**`exit`**|Animation name to run when not render (***enable=false***).
Example: ***exit='fadeOut'*** |None|

|**`style`**|Same *react-native* style for `View`. |None|

|**`keepAlive`**|When ***enable=false*** 
 If `true` components will hide only ([`componentWillUnmount()`](https://facebook.github.io/react/docs/react-component.html#componentwillunmount) will not fire). 
If `false` components will not render at all. Use it on complex components or on modules that required init on everytime that they are mount (for example: [react-native-camera](https://github.com/lwansbrough/react-native-camera)).  |`false`|



### Using inspector to validate that after exit animation component will not render:

## Full example:

```js

import React, { Component } from 'react';

import {

  AppRegistry,

  StyleSheet,

  Text,

  View,

  Button,

} from 'react-native';



import Display from 'react-native-display';



export default class testdisplay extends Component {

  constructor(props) {

    super(props);



    this.state = {enable: true};

  }



  toggleDisplay() {

    let toggle = !this.state.enable;

    this.setState({enable: toggle});

  }



  render() {

    return (

      

        

          

        

        

          

            

          

          

            

          

          

            

          

        

      

    );

  }

}



const styles = {

  button: {

    padding: 10,

    margin: 15,

  },

  center: {

    flexDirection: 'row',

    justifyContent: 'space-between',

    alignItems: 'center',

  },

  circle: {

    borderRadius: 50,

    height: 100,

    width: 100,

    margin: 15

  },

}



AppRegistry.registerComponent('testdisplay', () => testdisplay);

```
