What is SVGR?
SVGR is an universal tool to transform SVG into React components.
SVGR takes a raw SVG and transforms it into a ready-to-use React component.
For example, take the following SVG:
<?xml version="1.0" encoding="UTF-8"?>
<svg
width="48px"
height="1px"
viewBox="0 0 48 1"
version="1.1"
xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
>

<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>
</g>
</g>
</g>
</g>
</g>
</g>
</svg>
After running SVGR, we got:
import * as 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" />
</svg>
)
export default SvgComponent
To achieve this result, SVGR applies several complex transformations:
- Optimizing using SVGO
- Transforming HTML into JSX in several steps:
- Converting SVG into HAST (HTML AST)
- Converting HAST into Babel AST (JSX AST)
- Transforming AST using Babel (renaming attribute, changing attribute values, ...)
- Wrapping JSX into a React Component
- Converting Babel AST into code
- Formatting code using Prettier
This complex pipeline makes SVGR a reliable, safe and extendable tool.
It can be used through:
- Online playground
- Command line tool
- webpack loader
- Node.js API
- rollup.js plugin
- parcel plugin
- Next.js plugin
It is just the list of official integrations, but the community around SVGR is huge. If you are looking for a plugin, it probably already exists. Give a look to ecosystem to learn more about existing SVGR integrations.
