swgs

The swgs module is compatibility layer between react-native-svg and regular react (browser) based SVG elements, forked from the svgs module to support react-native-web. This allows you to write SVG in the react and react-native using exactly the same API. Bringing your applications a step closer to writing fully isomorphic application.

The library itself is written in ES6 and comes with the correct babel transforms as dependencies so it's easy to integrate in your existing tool chains and webpack builds.

There are 2 ways in using this package, you could use swgs instead of react-native-svg which is recommended. But you could also instruct your WebPack builder to use swgs as an alias for react-native-svg.

Install

For regular react usage:

npm install --save swgs

For React-Native usage:

npm install --save swgs
npm install --save react-native-svg
react-native link react-native-svg

Word of caution, make sure that you install a react-native-svg version that works with your react-native version. See the react-native-svg project for a list of supported React versions.

WebPack

To use this package as alias for react-native-svg you need to update your WebPack configuration to include the following snippet:

resolve: {
  alias: {
    ...
    'react-native-svg': 'swgs',
  }
}

API

The API that we expose is exactly the same as the react-native-svg project so please visit: https://github.com/react-native-community/react-native-svg for the full API documentation. But here is a quick little overview of the available elements:

import Svg, {
  Circle,
  ClipPath,
  Defs,
  Ellipse,
  G,
  Image,
  Line,
  LinearGradient,
  Mask,
  Path,
  Pattern,
  Polygon,
  Polyline,
  RadialGradient,
  Rect,
  Stop,
  Svg,
  Symbol,
  TSpan,
  Text,
  TextPath,
  Use,
} from 'swgs';

Any incompatibilities should be seen as a bug and be reported in the swgs/issue page on Github.

Example

Import all the SVG elements and make a Twitter logo.

import React, { Component } from 'react';
import Svg, { Path } from 'swgs';

class Twitter extends Component {
  render() {
    return (
      <Svg
        height="1208"
        width="1000"
        viewbox="0 0 1000 1208.3"
        preserveAspectRatio="meet"
      >
        <Path
          fill="#000"
          d="M0 1007.9q139.6 92.1 305.8 92.1 76.7 0 146.9-18.1 70.2-18.1 126.5-50 56.2-31.9 103.9-75.6 47.7-43.8 82.5-95.7 34.8-51.8 59.2-108.9 24.4-57.1 36.5-116.3 12-59.1 12-117.5 0-17.9-0.4-26.6 13.4-10 42.1-25.5 28.8-15.4 51-30.8 22.3-15.4 34-33.3-15.8 7.1-41.5 10-25.6 2.9-56.4 3.7-30.8 0.9-44.2 2.5 34.6-21.6 69.2-58.1 34.6-36.5 45-69.8-31.3 19.2-76.3 38.3-45 19.2-77 25.9-28-30.4-65.7-47.5-37.7-17.1-79.8-17.1-54.1 0-100.2 27.5-46 27.5-72.7 74.6-26.6 47.1-26.6 102.5 0 24.1 5 46.6-122.5-6.6-229.4-63.1-106.9-56.4-181.9-150.6-26.7 46.7-26.7 102.9 0 52.1 23.8 97.1 23.7 45 64.6 72.9-48.4-1.2-90-25.4l0 2.5q0 73.7 45.4 130.2 45.4 56.5 114.6 70.2-25 7.5-52.5 7.5-19.2 0-37.9-3.7 19.1 61.6 70.4 101.2 51.2 39.6 116.2 40.8-108.7 87.5-247.9 87.5-25.8 0-47.5-2.9z"
        />
      </Svg>
    );
  }
}

Accessibility

If you want Section 508 Accessibility add the title prop to the <Svg /> component like this:

<Svg title="Image Description" width="1000" height="1000" ... />

When this renders on native, you'll get your SVG wrapped in a View with an accessibilityLabel. On web, the SVG element will get two aria labels and a <title> element that are required for accessibility.

<svg role="img" aria-label="[title]" width="1000" height="1000">
  <title>Image Description</title>
  ...
</svg>
