Background
Let's say you have an SVG available at some URL, and you'd like to inject it into the DOM for various reasons. This module does the heavy lifting for you by delegating the process to @tanem/svg-injector, which makes an AJAX request for the SVG and then swaps in the SVG markup inline. The async loaded SVG is also cached, so multiple uses of an SVG only require a single server request.
Basic Usage
import { createRoot } from 'react-dom/client'
import { ReactSVG } from 'react-svg'
const container = document.getElementById('root')
const root = createRoot(container)
root.render(<ReactSVG src="svg.svg" />)Live Examples

API
Props
src- The SVG URL.afterInjection(svg)- Optional Function to call after the SVG is injected.svgis the injected SVG DOM element. If an error occurs during execution it will be routed to theonErrorcallback, and if afallbackis specified it will be rendered. Defaults to() => {}.beforeInjection(svg)- Optional Function to call just before the SVG is injected.svgis the SVG DOM element which is about to be injected. If an error occurs during execution it will be routed to theonErrorcallback, and if afallbackis specified it will be rendered. Defaults to() => {}.desc- Optional String used for SVG<desc>element content. If a<desc>exists it will be replaced, otherwise a new<desc>is created. Defaults to'', which is a noop.evalScripts- Optional Run any script blocks found in the SVG. One of'always','once', or'never'. Defaults to'never'.fallback- Optional Fallback to use if an error occurs during injection, or if errors are thrown from thebeforeInjectionorafterInjectionfunctions. Can be a string, class component, or function component. Defaults tonull.httpRequestWithCredentials- Optional Boolean indicating if cross-site Access-Control requests for the SVG should be made using credentials. Defaults tofalse.loading- Optional Component to use during loading. Can be a string, class component, or function component. Defaults tonull.onError(error)- Optional Function to call if an error occurs during injection, or if errors are thrown from thebeforeInjectionorafterInjectionfunctions.erroris anunknownobject. Defaults to() => {}.renumerateIRIElements- Optional Boolean indicating if SVG IRI addressable elements should be renumerated. Defaults totrue.title- Optional String used for SVG<title>element content. If a<title>exists it will be replaced, otherwise a new<title>is created. Defaults to'', which is a noop.useRequestCache- Optional Use SVG request cache. Defaults totrue.wrapper- Optional Wrapper element types. One of'div','span'or'svg'. Defaults to'div'.
Other non-documented properties are applied to the outermost wrapper element.

console.log('wrapper onClick')
}}
onError={(error) => {
console.error(error)
}}

useRequestCache={false}
wrapper="span"
/>Installation
⚠️This library depends on @tanem/svg-injector, which uses
Array.from(). If you're targeting browsers that don't support that method, you'll need to ensure an appropriate polyfill is included manually. See this issue comment for further detail.
$ npm install react-svgUMD builds are also available for use with pre-React 19 via unpkg:
- https://unpkg.com/react-svg/dist/react-svg.umd.development.js
- https://unpkg.com/react-svg/dist/react-svg.umd.production.js
For the non-minified development version, make sure you have already included:
For the minified production version, make sure you have already included:
FAQ
This module delegates it's core behaviour to @tanem/svg-injector, which requires the presence of a parent node when swapping in the SVG element. The swapping in occurs outside of React flow, so we don't want React updates to conflict with the DOM nodes @tanem/svg-injector is managing.
Example output, assuming a div wrapper:
<div> <!-- The wrapper, managed by React -->
<div> <!-- The parent node, managed by @tanem/svg-injector -->
<svg>...</svg> <!-- The swapped-in SVG, managed by @tanem/svg-injector -->
</div>
</div>See:
