React-native-loading-view NPM

react-native-loading-view

Loading view to show your user that magic is happening in the background.

Installation

Install and save it with npm...

npm install --save react-native-loading-view

Import it in the file you want to use it in...

import LoadingView from 'react-native-loading-view'

Usage

Just wrap the components you want to hide while loading in a LoadingView component. It won't show its children unless the prop loading is set to false.

// This LoadingView would never show its children
<LoadingView loading={true}>
    <Text>Im finished!</Text>
</LoadingView>

The LoadingView is highly customizable. You can use the following props:

Prop	Value type	Usage
loading	boolean	determines whether the loading view is shown or not
style	object	Style which applies on the outer container of the component
text	string	Text which is shown below the activity indicator
textStyle	object	Sets the style of the specified text. Be creative!
content	component	The content shown below the activity indicator. Will replace the default text specified in the `text` prop
textStyle	object	Styles which apply on the wrapping text element of the content string
indicator	component	The component which should indicate that something great is happening. By default it's an `<ActivityIndicator/>`.
size	large/small	The size of the activity indicator. Only applies if you use the default activity indicator.
overlay	boolean	If true, this will set the view as an absolute-positioned overlay over your content
overlayStyle	object	The style used when you use the overlay mode. It's applied on the container component.

Example

This is just a simple example with the default react-native app

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';
import LoadingView from 'react-native-loading-view'

export default class ReactNativeSandbox extends Component {

  constructor(props) {
    super(props)
    this.state = {
      loading: true
    }
  }

  componentDidMount = () => {
    // This is just meant as an example of how you handle an asynchronous operation
    // In reality this might be a fetch or storage access
    setTimeout(() => {
      this.setState({
        loading: false
      })
    }, 5000)
  }

  render() {
    return (
      <LoadingView loading={this.state.loading}>
        <View style={styles.container}>
          <Text style={styles.welcome}>
            Welcome to React Native!
          </Text>
          <Text style={styles.instructions}>
            To get started, edit index.ios.js
          </Text>
          <Text style={styles.instructions}>
            Press Cmd+R to reload,{'\n'}
            Cmd+D or shake for dev menu
          </Text>
        </View>
      </LoadingView>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

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