I want to show svg files (I have bunch of svg images) but the thing I couldn't find the way to show. I tried to use Image and Use components of react-native-svg but they don't work with that. And I tried to do that with native way but it's really hard work to show just svg image.
Example code:
import Svg, {
Use,
Image,
} from 'react-native-svg';
<View>
<Svg width="80" height="80">
<Image href={require('./svg/1f604.svg')} />
</SvgRn>
</View>
Also I know the react native doesn't support svg basically but I think someone fixed this problem with tricky way (with/without react-native-svg)
I used the following solution:
.svg
image to JSX with https://svg2jsx.herokuapp.com/react-native-svg
component with https://svgr.now.sh/ (check the "React Native checkbox)I posted another solution (react-native-vector-icons) here . This approach use a vector font (from SVG) instead a SVG file. PS: react-native-vector-icons is the best approach to deal with SVG in react-native, it's also works in iOS and android. You will be able to change the color and size of your vector icon.
If you want to insert a svg directly into your app, you can try a 3rd party library : react-native-svg. With more than 3k stars in github it's one of the best approach.
Install any one of these using npm
:
Then link it to native using
react-native link react-native-svg
An example with react-native-svg-uri
:
import * as React from 'react';
import SvgUri from 'react-native-svg-uri'; // SVG Package
import testSvg from './test.svg'; // SVG File
export default () => (
<SvgUri
width="200"
height="200"
svgXmlData={testSvg}
/>
);
Install react-native-svg-transformer
npm i react-native-svg-transformer --save-dev
I'm using SVG as following and it works fine
import LOGOSVG from "assets/svg/logo.svg"
in render
<View>
<LOGOSVG
width="100%"
height="70%"
/>
</View>
I've tried all the above solutions and other solutions outside of the stack and none of working for me. finally, after long research, I've found one solution for my expo project.
If you need it to work in expo, one workaround might be to use https://react-svgr.com/playground/ and move the spreading of props to a G element instead of the SVG root like this:
import * as React from 'react';
import Svg, { G, Path } from 'react-native-svg';
function SvgComponent(props) {
return (
<Svg viewBox="0 0 511 511">
<G {...props}>

}
export default function App() {
return (
<SvgComponent width="100%" height="100%" strokeWidth={5} stroke="black" />

}
you can do this using a simple way
const { getDefaultConfig } = require("metro-config"); module.exports = (async () => { const { resolver: { sourceExts, assetExts } } = await getDefaultConfig(); return { transformer: { babelTransformerPath: require.resolve("react-native-svg-transformer") }, resolver: { assetExts: assetExts.filter(ext => ext !== "svg"), sourceExts: [...sourceExts, "svg"] } }; })();
declare module "*.svg" { import { SvgProps } from "react-native-svg"; const content: React.FC<SvgProps>; export default content; }
Finally, This is a import mathod
import USER from "../../assets/icons/user.svg"
and, this is for jsx
<USER width="100%" height="100%"/>
I had the same problem. I'm using this solution I found: React Native display SVG from a file
It's not perfect, and i'm revisiting today, because it performs a lot worse on Android.
Use https://github.com/kristerkari/react-native-svg-transformer
In this package it is mentioned that .svg
files are not supported in React Native v0.57 and lower so use .svgx
extension for svg files.
For web or react-native-web use https://www.npmjs.com/package/@svgr/webpack
To render svg files using react-native-svg-uri
with react-native version 0.57 and lower, you need to add following files to your root project
Note: change extension
svg
tosvgx
transformer.js
to project's root// file: transformer.js
const cleanupSvg = require('./cleanup-svg');
const upstreamTransformer = require("metro/src/transformer");
// const typescriptTransformer = require("react-native-typescript-transformer");
// const typescriptExtensions = ["ts", "tsx"];
const svgExtensions = ["svgx"]
// function cleanUpSvg(text) {
// text = text.replace(/width="([#0-9]+)px"/gi, "");
// text = text.replace(/height="([#0-9]+)px"/gi, "");
// return text;
// }
function fixRenderingBugs(content) {
// content = cleanUpSvg(content); // cleanupSvg removes width and height attributes from svg
return "module.exports = `" + content + "`";
}
module.exports.transform = function ({ src, filename, options }) {
// if (typescriptExtensions.some(ext => filename.endsWith("." + ext))) {
// return typescriptTransformer.transform({ src, filename, options })
// }
if (svgExtensions.some(ext => filename.endsWith("." + ext))) {
return upstreamTransformer.transform({
src: fixRenderingBugs(src),
filename,
options
})
}
return upstreamTransformer.transform({ src, filename, options });
}
rn-cli.config.js
to project's rootmodule.exports = {
getTransformModulePath() {
return require.resolve("./transformer");
},
getSourceExts() {
return [/* "ts", "tsx", */ "svgx"];
}
};
The above mentioned solutions will work in production apps too ✅
SVG does not support directly in Native applications. For displaying those we need to take help of third party modules
Please follow these steps
step 1 . Install react-native-svg and react-native-svg-transformer
npm i react-native-svg react-native-svg-transformer
step 2 . Add file metro.config.js if it doesn't exist
const { getDefaultConfig } = require("metro-config");
module.exports = (async () => {
const {
resolver: {
sourceExts,
assetExts
}
} = await getDefaultConfig();
return {
transformer: {
babelTransformerPath: require.resolve("react-native-svg-transformer")
},
resolver: {
assetExts: assetExts.filter(ext => ext !== "svg"),
sourceExts: [...sourceExts, "svg"]
}};
})();
step 3 . Use SVG file like a React component
import Invest from '../assets/invest.svg'; // import SVG
return (
<View>
<Invest /> // Use SVG as component
</View>
)
you can convert any SVG to a component and make it reusable.
here is my answer for the easiest way you can do it
import React from 'react'
import SvgUri from 'react-native-svg-uri';
export default function Splash() {
return (
<View style={styles.container}>
{/* provided the svg file is stored locally */}
<SvgUri
width="400"
height="200"
source={require('./logo.svg')}
/>
{/* if the svg is online */}
<SvgUri
width="200"
height="200"
source={{ uri: 'http://thenewcode.com/assets/images/thumbnails/homer-simpson.svg' }}
/>
<Text style={styles.logoText}>
Text
</Text>
</View>
)
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center'
},
logoText: {
fontSize: 50
}
});
Using svg in a react native project is not as simple as using it in the web, although it is not that difficult either.
Many of the above answers are complicated in my view. So, here is the solution that I use and like.
Since react native does not support the svg file format directly you need to follow some steps to get it working.
1. Install react-native-svg
npm install react-native-svg --save
This package will help you render the svg file
2. Install react-native-svg-transformer
npm install react-native-svg-transformer --save
This package will transform your svg to the format that react native understands.
3. Import the svg as normal component
import Belsvg from "../assets/belsvg.svg";
While importing give it a name that you like now this svg is transformed into a react native component by the react-native-svg-transformer
4. Now you can use this as a normal component
For a detailed explanation and example visit the link:
https://kumar2396jayant.medium.com/how-to-use-svg-in-react-native-e581eca59534
ps: I would like to thank Jayant kumar yadav for posting that blog
Note: Svg does not work for android release versions so do not consider for android. It will work for android in debug mode only. But it works fine for ios.
Use https://github.com/vault-development/react-native-svg-uri
Install
npm install react-native-svg-uri --save
react-native link react-native-svg # not react-native-svg-uri
Usage
import SvgUri from 'react-native-svg-uri';
<SvgUri source={require('./path_to_image/image.svg')} />
I use these two plugins,
First off all, You need to install that plugin. After that you need to change your metro.config.js, with this code.
const { getDefaultConfig } = require("metro-config");
module.exports = (async () => {
const {
resolver: { sourceExts, assetExts }
} = await getDefaultConfig();
return {
transformer: {
babelTransformerPath: require.resolve("react-native-svg-transformer")
},
resolver: {
assetExts: assetExts.filter(ext => ext !== "svg"),
sourceExts: [...sourceExts, "svg"]
}
};
})();
For more details, you can visit this link
react-native-svg
to your project.Ex:- This is the sample SVG that I have got.
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="17" height="17" viewBox="0 0 17 17">

</mask>
<use fill="#FFF" fill-rule="nonzero" xlink:href="#a"/>
<g fill="#3D3D3D" mask="url(#b)">
<path d="M0 0h16v16H0z"/>
</g>
</g>
</svg>
Output:-
import * as React from "react"
import Svg, { Defs, Path, G, Mask, Use } from "react-native-svg"
function SvgComponent(props) {
return (
<Svg

</G>
</G>
</Svg>
)
}
export default SvgComponent
** But when I use the above code in my project and it does not render properly. So I done it as below and somehow it works for me.
import * as React from "react"
import Svg, { Path, G } from "react-native-svg"
function SvgComponent(props) {
return (
<Svg
width={17}
height={17}
{...props}
>
<G>
<Path

/>
</G>
</Svg>
)
}
export default SvgComponent
I've written a new library to be able to use native vector assets based on .svg
files called react-native-vector-image . It doesn't need any custom babel transforms and you can use it like you would for other bitmap based assets, but there is an extra step in transforming the svg to the native equivalents (you only need to run it when you add new assets though).
Using your example the code would look something like this
import VectorImage from 'react-native-vector-image';
<View>
<VectorImage source={require('./svg/1f604.svg')} />
</View>
Use react-native-svg see its supports both android and Ios.
this is the basic example
import * as React from 'react';
import { SvgUri } from 'react-native-svg';
export default () => (
<SvgUri
width="100%"
height="100%"
uri="http://thenewcode.com/assets/images/thumbnails/homer-simpson.svg"
/>
);
if you want to use both normal image and svg images in one component, You can make a custom function that checks if the url has svg and return Image component or SvgUri
const ImageComponent = (Props) => {
const {Istyle, url, mode} = props;
const isSvg = url?.includes('.svg') ?? false;
if (isSvg) {
return <SvgCssUri style={Istyle} uri={defaultAvatar} />;
}
if (!isSvg) {
return <Image style={Istyle} source={{uri: url}} resizeMode={mode} />;
}
};
//let testURl = "https://avatars.dicebear.com/api/male/john.svg"
The best solution that worked for me on both platforms is https://github.com/seekshiva/react-native-remote-svg .
I additionally did a conditional render with https://github.com/react-native-svg/react-native-svg to have the best result on both platforms, because there's an know issue with Android as stated here https://stackoverflow.com/a/54182426/4934132 .
Just in case I have ErrorBoundry to cover the exceptions.
It looks like this:
<ErrorBoundary
FallbackComponent={error => ErrorFallback(error)}
onReset={() => {
// reset the state of your app so the error doesn't happen again
}}
onError={myErrorHandler}
>
{Platform.OS === 'ios' ?
<SvgCssUri width="100%" height="100%" uri={url} />
:
<Image
source={{ uri: url }}
style={{ width: "100%", height: '100%' }}
/>
}
</ErrorBoundary>
Method that is working for me in 2022 for anyone that is still stuck on this, react native version 0.63.4, react-native-svg version ^12.1.0, you may be able to use this method for other versions too but always check the docs for the library first:
Install react-native-svg-transformer
by running this command yarn add react-native-svg-transformer --dev
or using npm if you prefer npm i react-native-svg react-native-svg-transformer --save-dev
Install babel-plugin-inline-import
by running yarn add babel-plugin-inline-import --dev
You need to update your metro.config.js
file to looks like this:
const { getDefaultConfig } = require('metro-config'); module.exports = (async () => { const { resolver: { sourceExts, assetExts } } = await getDefaultConfig(); return { transformer: { babelTransformerPath: require.resolve('react-native-svg-transformer'), getTransformOptions: async () => ({ transform: { experimentalImportSupport: false, inlineRequires: false } }) }, resolver: { assetExts: assetExts.filter(ext => ext !== 'svg'), sourceExts: [...sourceExts, 'svg'] } }; })();
Make sure to import your svg file into your component like this: import CreditCard from '../assets/CreditCard';
please note how I am not adding the .svg
file extension to the import, this is because it was giving me this error view config getter callback react-native-svg
while running it but removing it seems to make it run smoothly. You can add your file this way as a jsx element like that <CreditCard />
.
Finally Restart your packager by stopping it using ^Ctrl + C
on mac then restart it again with this command yarn start:dev --reset-cache
and install the app again.
You can try Converting .svg image to JSX with https:\/\/svg2jsx.herokuapp.com\/<\/a>
<\/li>
<\/li><\/ul> Make sure to install, yarn add react-native-svg
Incase anyone is stuck on this bug in 2022, here's the solution that worked for me:
Install react-native-svg-transformer :
yarn add react-native-svg-transformer --dev
or using npm
npm install react-native-svg-transformer --save-dev
Install react-native-svg :
yarn add react-native-svg
or using npm
npm install react-native-svg --save
Update your metro.config.js file to looks like this:
// Learn more https://docs.expo.io/guides/customizing-metro
const { getDefaultConfig } = require('expo/metro-config');
module.exports = (() => {
const {
resolver: {
sourceExts,
assetExts
}
} = getDefaultConfig(__dirname);
return {
transformer: {
babelTransformerPath: require.resolve("react-native-svg-transformer")
},
resolver: {
assetExts: assetExts.filter(ext => ext !== "svg"),
sourceExts: [...sourceExts, "svg"]
}};
})();
svg
image in your code like below:import {View} from 'react-native';
import SvgImage from './path/to/svg/file.svg';
function MyComponent(){
return (
<View>
<SvgImage />
</View>
)
}
If you're using React Native with TypeScript, here is the step-by-step solution:
1. Install react-native-svg
npm install react-native-svg
or
yarn add react-native-svg
2. Link native code
cd ios && pod install
3. Install react-native-svg-transformer
npm install --save-dev react-native-svg-transformer
or
yarn add --dev react-native-svg-transformer
4. Configure the react native packager
For React Native v0.59 or newer :
Merge the contents from your project's metro.config.js
file with this config (create the file if it does not exist already).
const { getDefaultConfig } = require("metro-config");
module.exports = (async () => {
const {
resolver: { sourceExts, assetExts }
} = await getDefaultConfig();
return {
transformer: {
babelTransformerPath: require.resolve("react-native-svg-transformer")
},
resolver: {
assetExts: assetExts.filter(ext => ext !== "svg"),
sourceExts: [...sourceExts, "svg"]
}
};
})();
This is how my merged metro.config.js
looks like:
const { getDefaultConfig } = require('metro-config')
module.exports = (async () => {
const {
resolver: { sourceExts, assetExts },
} = await getDefaultConfig()
return {
transformer: {
babelTransformerPath: require.resolve('react-native-svg-transformer'),
getTransformOptions: async () => ({
transform: {
experimentalImportSupport: false,
inlineRequires: true,
},
}),
},
resolver: {
assetExts: assetExts.filter((ext) => ext !== 'svg'),
sourceExts: [...sourceExts, 'svg'],
},
}
})()
5. TypeScript configuration:
If you are using TypeScript, you need to add this to your declarations.d.ts
file (create one if you don't have one already):
declare module "*.svg" {
import React from 'react';
import { SvgProps } from "react-native-svg";
const content: React.FC<SvgProps>;
export default content;
}
