svg-to-react-native-cli

Based on svg-to-react-cli. A command line utility that takes a svg image file and outputs a fully formatted stateless functional React Native component with height and width for props. With flags to toggle formatting and remove style attributes.

To Use

npm install -g svg-to-react-naive-cli

One File

svg-to-react-native src/svg/images/logo Logo --output ./src/svg/components/

NOTE: image file must be in current working directory. Do not add the extension. If file is image.svg, then just enter image as the first argument. ComponentName will be the name of the sfc and filename with .js appended.

Multi File

svg-to-react-native --dir src/svg/images/ --output ./src/svg/components/

or for all files in directory (will name all components in CamelCase based on image name. If image is image.svg then new component will be Image and file will be Image.js):

Optional Flags:

-d, --directory <path> - the dirctory from project folder to your svg images (./src/svg/images) (optional)

-o, --output <path> - the output path. Do not include the filename.

--help - Prints out this readme.

--example - Prints an example of the i/o of this util.

Example

Takes this:

<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 15.1.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

</svg>

And creates a new file with this:

import React from 'react';
import {
  Svg,
  Circle,
  Ellipse,
  G,
  LinearGradient,
  RadialGradient,
  Line,
  Path,
  Polygon,
  Polyline,
  Rect,
  Symbol,
  Text,
  Use,
  Defs,
  Stop
} from 'react-native-svg';

export default function TestSvg(props) {
  return (
    <Svg height="128px" id="Layer_1" width="128px" version="1.1" viewBox="0 0 128 128" x="0px" y="0px" xmlSpace="preserve">

    		<Path d="M74,81.5H54c-1.3..." fill="#242424"/>
    	</G>
    </Svg>
  );
}

Width / height order of precedence

The order of precedence of how width/height is set on a generated component is as follows:

  • 1 - Passed in width and height props are always priority one. This gives run time control to the container.
  • 2 - If a svg has its width/height set, this will be the first fallback if width/height props are not provided.
  • 3 - If the svg has not provided width/height attributes, the svg's viewbox's width/height segments are used as the fallback if width/height props are not provided.
  • 4 - Finally, if the svg has no width/height attributes, and the svg also doesn't have a viewbox - a fallback of 50px is applied to the width and height
