react-native-image-progress

Progress indicator for networked images in React Native

Installation

npm install --save react-native-image-progress

Note: Progress indicators has been broken out to a separate component; react-native-progress. To use them, please follow installation instructions for that package.

Usage

import Image from 'react-native-image-progress';
import ProgressBar from 'react-native-progress/Bar';
<Image 
  source={{ uri: 'http://loremflickr.com/640/480/dog' }} 
  indicator={ProgressBar} 
  style={{
    width: 320, 
    height: 240, 
  }}/>

Properties

Any Image property and the following:

Prop	Description	Default
indicator	A component to display progress, will be passed a progress prop with a number between 0 and 1 and indeterminate a boolean wether or not component has started recieveing data.	ActivityIndicatorIOS or ProgressBarAndroid
indicatorProps	An object of props being passed to the indicator component. To disable indeterminate state, pass {indeterminate: false}.	None
renderIndicator(progress, indeterminate)	Function to render your own custom indicator, useful for something very simple. If not, consider breaking it out to a separate component and use indicator prop instead.	None
threshold	Number of milliseconds after mount to wait before displaying the indicator. Basically a workaround for cached images not to flash a spinner. Set to 0 to disable.	50

Note: onLoad* events are bubbled up, so if you wan't to do some custom thing when the image is loaded for example.
