react-native-svg-transformer

React Native SVG transformer allows you import SVG files in your React Native project the same way that you would in a Web application when a using library like SVGR to transform your imported SVG images into React components.

This makes it easy to use the same code for React Native and Web.

Usage

Import your .svg file inside a React component:

import Logo from "./logo.svg";

You can then use your image as a component:

<Logo width={120} height={40} />

If you use React Native version 0.56 or older, you need to rename your .svg files to .svgx.

Installation and configuration

Step 1: Install react-native-svg library

Make sure that you have installed and linked react-native-svg library:

• https://github.com/react-native-community/react-native-svg#installation

Step 2: Install react-native-svg-transformer library

yarn add --dev react-native-svg-transformer

Step 3: Configure the react native packager

For React Native v0.57 or newer

Add this to your rn-cli.config.js (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"]
    }
  };
})();

For React Native v0.56 or older

React Native versions older than 0.57 do not support running the transformer for .svg file extension. That is why a .svgx file extension should be used instead for your SVG files. This is fixed in React Native 0.57 and newer versions.

Add this to your rn-cli.config.js (create the file if it does not exist already):

module.exports = {
  getTransformModulePath() {
    return require.resolve("react-native-svg-transformer");
  },
  getSourceExts() {
    return ["js", "jsx", "svgx"];
  }
};

...or if you are using Expo, in app.json:

{
  "expo": {
    "packagerOpts": {
      "sourceExts": ["js", "jsx", "svgx"],
      "transformer": "node_modules/react-native-svg-transformer/index.js"
    }
  }
}

Dependencies

In addition to React Native, this transfomer depends on the following libraries:

• react-native-svg
• react-native-svg-loader
