🚩 FastImage

Performant React Native image component.

FastImage example app.

React Native's Image component handles image caching like browsers for the most part. If the server is returning proper cache control headers for images you'll generally get the sort of built in caching behavior you'd have in a browser. Even so many people have noticed:

Flickering.
Cache misses.
Low performance loading from cache.
Low performance in general.

FastImage is an Image replacement that solves these issues. FastImage is a wrapper around SDWebImage (iOS) and Glide (Android).

Features

Usage

Note: You must be using React Native 0.60.0 or higher to use the most recent version of react-native-fast-image.

1yarn add react-native-fast-image
2cd ios && pod install

1import FastImage from 'react-native-fast-image'
2
3const YourImage = () => (
4    <FastImage
5        style={{ width: 200, height: 200 }}
6        source={{
7            uri: 'https://unsplash.it/400/400?image=1',
8            headers: { Authorization: 'someAuthToken' },
9            priority: FastImage.priority.normal,
10        }}
11        resizeMode={FastImage.resizeMode.contain}
12    />
13)

Are you using Glide already using an AppGlideModule?

Are you using Glide already using an AppGlideModule? (you might have problems if you don't read this)

Are you using Proguard?

If you use Proguard you will need to add these lines to android/app/proguard-rules.pro:

-keep public class com.dylanvann.fastimage.* {*;}
-keep public class com.dylanvann.fastimage.** {*;}
-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.module.AppGlideModule
-keep public enum com.bumptech.glide.load.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}

Properties

`source?: object`

Source for the remote image to load.

`source.uri?: string`

Remote url to load the image from. e.g. 'https://facebook.github.io/react/img/logo_og.png'.

`source.headers?: object`

Headers to load the image with. e.g. { Authorization: 'someAuthToken' }.

`source.priority?: enum`

FastImage.priority.low - Low Priority.
FastImage.priority.normal (Default) - Normal Priority.
FastImage.priority.high - High Priority.

`source.cache?: enum`

FastImage.cacheControl.immutable - (Default) - Only updates if url changes.
FastImage.cacheControl.web - Use headers and follow normal caching procedures.
FastImage.cacheControl.cacheOnly - Only show images from cache, do not make any network requests.

`defaultSource?: number`

An asset loaded with require(...).
Note that like the built-in Image implementation, on Android defaultSource does not work in debug mode. This is due to the fact that assets are sent from the dev server, but RN's functions only know how to load it from res.

`resizeMode?: enum`

FastImage.resizeMode.contain - Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the view (minus padding).
FastImage.resizeMode.cover (Default) - Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).
FastImage.resizeMode.stretch - Scale width and height independently, This may change the aspect ratio of the src.
FastImage.resizeMode.center - Do not scale the image, keep centered.

`onLoadStart?: () => void`

Called when the image starts to load.

`onProgress?: (event) => void`

Called when the image is loading.

e.g. onProgress={e => console.log(e.nativeEvent.loaded / e.nativeEvent.total)}

`onLoad?: (event) => void`

Called on a successful image fetch. Called with the width and height of the loaded image.

e.g. onLoad={e => console.log(e.nativeEvent.width, e.nativeEvent.height)}

`onError?: () => void`

Called on an image fetching error.

`onLoadEnd?: () => void`

Called when the image finishes loading, whether it was successful or an error.

`style`

A React Native style. Supports using borderRadius.

`fallback: boolean`

If true will fallback to using Image. In this case the image will still be styled and laid out the same way as FastImage.

`tintColor?: number | string`

If supplied, changes the color of all the non-transparent pixels to the given color.

Static Methods

`FastImage.preload: (source[]) => void`

Preload images to display later. e.g.

1FastImage.preload([
2    {
3        uri: 'https://facebook.github.io/react/img/logo_og.png',
4        headers: { Authorization: 'someAuthToken' },
5    },
6    {
7        uri: 'https://facebook.github.io/react/img/logo_og.png',
8        headers: { Authorization: 'someAuthToken' },
9    },
10])

`FastImage.clearMemoryCache: () => Promise<void>`

Clear all images from memory cache.

`FastImage.clearDiskCache: () => Promise<void>`

Clear all images from disk cache.

Supported React Native Versions

This project only aims to support the latest version of React Native.
This simplifies the development and the testing of the project.

If you require new features or bug fixes for older versions you can fork this project.

Credits

The idea for this modules came from vovkasm's react-native-web-image package. It also uses Glide and SDWebImage, but didn't have some features I needed (priority, headers).

Thanks to @mobinni for helping with the conceptualization
