- Faster render – ~5x faster than
react-native-svg. - Smaller JS bundle = faster startup.
- Native support for dark mode.
yarn add react-native-vector-image @klarna/react-native-vector-drawableEdit android/app/build.gradle to look like this (without the +):
project.ext.react = [
enableHermes: false, // clean and rebuild if changing
]
apply from: "../../node_modules/react-native/react.gradle"
+ apply from: "../../node_modules/react-native-vector-image/strip_svgs.gradle"Open your project in Xcode, select the Build Phases tab, and edit the Bundle React Native code and images script to look like this (without the +):
set -e
export NODE_BINARY=node
../node_modules/react-native/scripts/react-native-xcode.sh
+ ../node_modules/react-native-vector-image/strip_svgs.sh
Since native vector assets cannot be served over http via metro dev server, they must be generated and compiled into the app bundle.
import VectorImage from 'react-native-vector-image';
const App = () => <VectorImage source={require('./image.svg')} />;To add dark mode to your image, create a new file with an .dark.svg extension, ie image.svg = light and image.dark.svg = dark.
This takes a while as metro has to go through all the code to find the imported SVGs.
yarn react-native-vector-image generate| Argument | Description | Default |
|---|---|---|
--entry-file |
Path to the app entrypoint file. | index.js |
--config |
Path to the metro config file. | metro.config.js |
--reset-cache |
Reset metro cache before extracting SVG assets. | false |
--ios-output |
Path to an iOS .xcassets folder. |
ios/AppName/Images.xcassets |
--no-ios-output |
Disable iOS output. | false |
--android-output |
Path to an Android res folder. |
android/app/src/main/res |
--no-android-output |
Disable Android output. | false |
--current-color |
Replace any currentColor color references in SVGs. |
#000000 |
--current-color-dark |
Replace any currentColor color references in .dark.svg SVGs. |
#ffffff |
yarn react-native run-ios
# or
yarn react-native run-androidSome optimizations applied by SVGO are not compatible with the SVG parser on Android. Try to re-export the SVG without optimizing it.
It means that the native vector asset does not exist or is out of sync with the SVG. Simply generate the files and recompile the app.
Make sure your image component is used (imported) somewhere in your code, otherwise the asset generator won't find it.
