Vectorinox

Cleans up and compresses SVG files exported from Sketch (and other design tools). Optionally formats SVG as JSX for inlining into React projects.

Install

> npm install -g vectorinox

Example Usage

To optimize an SVG file in place:

> vectorinox vector-file-to-optimize.svg

To output the optimized SVG to stdout:

> vectorinox --stdout vector-file-to-optimize.svg

Full Usage

vectorinox [options] svgfile ... svgfile

Output:
  --stdout, -o  Print results to stdout instead of writing to file                   [boolean] [default: false]

                                                           with a .js extension using the default template
  vectorinox --jsx image.svg --jsx-template                Optimize a file and convert it to a React module
  mySvgTemplate.js                                         with a .js extension using the provided template
  vectorinox --jsx --jsx-extension tsx image.svg           Optimize a file and convert it to a React module

React/JSX

To prep and format SVG for inlining in your React codebase, use the --jsx option.

> vectorinox --jsx --stdout vector-file-to-optimize.svg

<svg stroke="#444444" strokeWidth={2} fill="none">
  <rect x={8} y={3} width={32} height={41} rx={3} />
  <circle fill="#CFE9FF" cx={15} cy={10} r={3} />
  <path d="M22.4375,10 L35.5625,10" />
</svg>

You can pipe the output to pbcopy (Mac) or clip (Windows) for easy pasting into your code:

> vectorinox --jsx --stdout vector-file-to-optimize.svg | pbcopy

You can customize the root tag and props assigned to it. For example, if you use JSXStyle, you can output <View component="svg" /> instead of <svg />:

> vectorinox --jsx --stdout vector-file-to-optimize.svg --jsxTag View --jsxProp component=svg

<View stroke="#444444" strokeWidth={2} fill="none" component="svg">
  <rect x="#CFE9FF" cx="M22.4375,10 L35.5625,10" />
  <circle cx="M22.4375,19 L35.5625,19" />
</View>

You can even specify which props to pass through from the parent:

> vectorinox --jsx --stdout vector-file-to-optimize.svg --jsxTag View --jsxProp component=svg --jsxInheritProp stroke --jsxInheritProp fill

<View stroke={stroke} strokeWidth={2} fill={fill} component="svg">
  <rect x="#CFE9FF" cx="M22.4375,10 L35.5625,10" />
  <circle cx="M22.4375,19 L35.5625,19" />
</View>

Or which props object to splice in:

> vectorinox --jsx --stdout vector-file-to-optimize.svg --jsxTag View --jsxProp component=svg --jsxSpliceProp props

<View component="svg" {...props}>
  <rect x="#CFE9FF" cx="M22.4375,10 L35.5625,10" />
  <circle cx="M22.4375,19 L35.5625,19" />
</View>

If you use the --jsx option without --stdout, a .js file with the same name as the .svg file will be created. To customize the extension used, use --jsxExtension tsx.

React Component Templates

It usually takes a small amount of boilerplate to convert an SVG image to a valid React component. Vectorinox comes with a default template used when converting to JSX. It looks like this:

import * as React from 'react';

const %NAME% = (%PROPS%) =>
  %SVG%;

export default %NAME%;

You can customize the template by providing a --jsxTemplate template.js option, or by creating a file called .svgTemplate.js in the current directory.

Available placeholders are:

• %NAME%: a CamelCased version of the SVG file name.
• %PROPS%: an object destructuring of props, inferred from the --jsxInheritProp and --jsxSpliceProp options provided. For example, with --jsxInheritProp color --jsxInheritProp fill --jsxSpliceProp props, this token gets replaced with {color, fill, ...props}.
• %SVG%: the actual converted SVG markup. Put this on its own line with space in front of it to indent the code accordingly.

Known Issues

Not all of SVG is currently supported. Specifically masks and transforms on paths that use arc segments are known to be broken.
