Tests npm

Installation

yarn add react-native-vector-image @klarna/react-native-vector-drawable

For expo, see @zamplyy/react-native-vector-image-plugin.

Android

Edit 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"

iOS

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

Usage

Since native vector assets cannot be served over http via metro dev server, they must be generated and compiled into the app bundle.

Step 1: import an .svg file

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.

Step 2: generate native assets

This takes a while as metro has to go through all the code to find the imported SVGs.

yarn react-native-vector-image generate
ArgumentDescriptionDefault
--entry-filePath to the app entrypoint file.index.js
--configPath to the metro config file.metro.config.js
--reset-cacheReset metro cache before extracting SVG assets.false
--ios-outputPath to an iOS .xcassets folder.ios/AppName/Images.xcassets
--no-ios-outputDisable iOS output.false
--android-outputPath to an Android res folder.android/app/src/main/res
--no-android-outputDisable Android output.false
--current-colorReplace any currentColor color references in SVGs.#000000
--current-color-darkReplace any currentColor color references in .dark.svg SVGs.#ffffff

Step 3: recompile

yarn react-native run-ios
# or
yarn react-native run-android

Troubleshooting

generate command outputs "Error while parsing image.svg"

Some optimizations applied by SVGO are not compatible with the SVG parser on Android. Try to re-export the SVG without optimizing it.

<VectorImage /> warns "Could not find image"

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.

the generate command does not generate any new assets

Make sure your image component is used (imported) somewhere in your code, otherwise the asset generator won't find it.
