npm install @svgr/cli


Take an icon.svg:

<?xml version="1.0" encoding="UTF-8"?>
<svg width="48px" height="1px" viewBox="0 0 48 1" version="1.1" xmlns="" xmlns:xlink="">
    <!-- Generator: Sketch 46.2 (44496) - -->
    <title>Rectangle 5</title>
    <desc>Created with Sketch.</desc>
    <g id="Page-1" stroke="none" stroke-width="1" fill="none" fill-rule="evenodd">
        <g id="19-Separator" transform="translate(-129.000000, -156.000000)" fill="#063855">
            <g id="Controls/Settings" transform="translate(80.000000, 0.000000)">
                <g id="Content" transform="translate(0.000000, 64.000000)">
                    <g id="Group" transform="translate(24.000000, 56.000000)">
                        <g id="Group-2">
                            <rect id="Rectangle-5" x="25" y="36" width="48" height="1"></rect>


svgr --icon --replace-attr-values "#063855=currentColor" icon.svg


import React from 'react'

const SvgComponent = props => (
  <svg width="1em" height="1em" viewBox="0 0 48 1" {...props}>
    <path d="M0 0h48v1H0z" fill="currentColor" fillRule="evenodd" />

export default SvgComponent


React supports SVG out of the box, it's simpler, easier and much more powerful to have components instead of SVG files. Wrapped in a React component, your SVG is inlined in the page and you can style it using CSS.

There are a lot of similar projects, but I wanted something more solid and configurable. SVGR is based on h2x, a powerful and configurable HTML transpiler. It uses AST (like Babel) that gives a lot of power.

    svgr --replace-attr-values "#fff=currentColor" icon.svg


Transform a whole directory

A whole directory can be processed, all SVG files (matching .svg or .SVG) are transformed into React components.

# Usage: svgr [-d out-dir] [src-dir]
$ svgr -d icons icons
icons/web/clock-icon.svg -> icons/web/ClockIcon.js
icons/web/wifi-icon.svg -> icons/web/WifiIcon.js
icons/spinner/cog-icon.svg -> icons/spinner/CogIcon.js
icons/spinner/spinner-icon.svg -> icons/spinner/SpinnerIcon.js

Use stdin

$ svgr < icons/web/wifi-icon.svg

Use stdin / stdout

$ svgr < icons/web/wifi-icon.svg > icons/web/WifiIcon.js

Transform icons

To create icons, two options are important:

  • --icon: viewBox is preserved and SVG inherits text size
  • --replace-attr-values "#000000=currentColor": "#000000" is replaced by "currentColor" and SVG inherits text color
$ svgr --icon --replace-attr-values "#000000=currentColor" my-icon.svg

Target React Native

It is possible to target React Native using react-native-svg.

$ svgr --native my-icon.svg

Use a specific template

You can use a specific template.

$ svgr --template path/to/template.js my-icon.svg

You can find template examples in templates folder.

Node API usage

SVGR can also be used programmatically:

import svgr from '@svgr/core'

const svgCode = `
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns=""
  <rect x="10" y="10" height="100" width="100"
    style="stroke:#ff0000; fill: #0000ff"/>

svgr(svgCode, { icon: true }, { componentName: 'MyComponent' }).then(jsCode => {

Webpack loader

Rollup plugin



SVGR uses cosmiconfig for configuration file support. This means you can configure prettier via:

  • A .svgrrc file, written in YAML or JSON, with optional extensions: .yaml/.yml/.json/.js.
  • A svgr.config.js file that exports an object.
  • A "svgr" key in your package.json file.

The configuration file will be resolved starting from the location of the file being formatted, and searching up the file tree until a config file is (or isn't) found.

The options to the configuration file are the same as the API options.



  "icon": true,
  "expandProps": false


// .svgrrc.js
module.exports = {
  icon: true,
  expandProps: false,


# .svgrrc
icon: true
expandProps: false


The recommended way to configure Prettier for SVGR is to use .prettierrc. It is fully supported in all formats available and it is relative to the transformed SVG file.

Even if it is not recommended, you can also use prettierConfig option to specify your Prettier configuration. prettierConfig has precedence on .prettierrc.


The recommended way to configure SVGO for SVGR is to use .svgo.yml. Several formats are suported and it is relative to the transformed SVG file.

Even if it is not recommended, you can also use svgoConfig option to specify your SVGO configuration. svgoConfig has precedence on .svgo.yml.


SVGR ships with a handful of customizable options, usable in both the CLI and API.

File extension

Specify a custom extension for generated files.

Default CLI Override API Override
"js" --ext ext: <string>


Replace SVG "width" and "height" value by "1em" in order to make SVG size inherits from text size.

Default CLI Override API Override
false --icon icon: <bool>


Modify all SVG nodes with uppercase and use a specific template with react-native-svg imports. All unsupported nodes will be removed.

Default CLI Override API Override
false --native native: <bool>


Remove width and height from root SVG tag.

Default CLI Override API Override
false --no-dimensions dimensions: <bool>

Expand props

All properties given to component will be forwarded on SVG tag.

Default CLI Override API Override
true --no-expand-props expandProps: <bool>


Use Prettier to format JavaScript code output.

Default CLI Override API Override
true --no-prettier prettier: <bool>

Prettier config

Specify Prettier config. See Prettier options.

Default CLI Override API Override
null --prettier-config prettierConfig: <object>


Use SVGO to optimize SVG code before transforming it into a component.

Default CLI Override API Override
true --no-svgo svgo: <bool>

SVGO config

Specify SVGO config. See SVGO options.

Default CLI Override API Override
null --svgo-config svgoConfig: <object>


Setting this to true will allow you to hook into the ref of the svg components that are created by exposing a svgRef prop

Default CLI Override API Override
false --ref ref: <bool>

Replace attribute value

Replace an attribute value by an other. The main usage of this option is to change an icon color to "currentColor" in order to inherit from text color.

Default CLI Override API Override
[] --replace-attr-values <old=new> replaceAttrValues: { old: 'new' }>

SVG props

Add props to the root SVG tag.

Default CLI Override API Override
[] --svg-props <name=value> svgProps: { name: 'value' }>

You can specify dynamic property using curly braces: { focusable: "{true}" } or --svg-props focusable={true}. It is particulary useful with a custom template.


Specify a template file (CLI) or a template function (API) to use. For an example of template, see the default one.

Default CLI Override API Override
reactDomTemplate --template template: <func>

Output Directory

Output files into a directory.

Default CLI Override API Override
undefined --out-dir <dirname> outDir: <dirname>
