A React component that injects SVG into the DOM.

Background | Basic Usage | Live Examples | API | Installation | FAQ | License

This component uses @tanem/svg-injector to fetch an SVG from a given URL and inject its markup into the DOM (why?). Fetched SVGs are cached, so multiple uses of the same SVG only require a single request.

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" />)

Props

• src - The SVG URL. Supports fetchable URLs (relative or absolute), data:image/svg+xml URLs (URL-encoded or base64), and SVG sprite sheets via fragment identifiers (e.g. sprite.svg#icon-star). See the data URL example and sprite usage example.
• afterInjection(svg) - Optional Function to call after the SVG is injected. svg is the injected SVG DOM element. If an error occurs during execution it will be routed to the onError callback, and if a fallback is specified it will be rendered. Defaults to () => {}.
• beforeInjection(svg) - Optional Function to call just before the SVG is injected. svg is the SVG DOM element which is about to be injected. If an error occurs during execution it will be routed to the onError callback, and if a fallback is 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. When set, a unique id is added to the <desc> element and aria-describedby is set on the SVG for assistive technology. 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 the beforeInjection or afterInjection functions. Can be a string, class component, or function component. Defaults to null.
• httpRequestWithCredentials - Optional Boolean indicating if cross-site Access-Control requests for the SVG should be made using credentials. Defaults to false.
• loading - Optional Component to use during loading. Can be a string, class component, or function component. Defaults to null.
• onError(error) - Optional Function to call if an error occurs during injection, or if errors are thrown from the beforeInjection or afterInjection functions. error is an unknown object. Defaults to () => {}.
• renumerateIRIElements - Optional Boolean indicating if SVG IRI addressable elements should be renumerated. Defaults to true. When enabled, IDs on IRI-addressable elements (clipPath, linearGradient, mask, path, etc.) are made unique, and all references to them (presentation attributes, href/xlink:href, inline style attributes, and <style> element text) are updated. Note: all matching element types are renumerated, not only those inside <defs>. Set to false if you need to query injected elements by their original IDs.
• title - Optional String used for SVG <title> element content. If a <title> exists it will be replaced, otherwise a new <title> is created. When set, a unique id is added to the <title> element and aria-labelledby is set on the SVG for assistive technology. Defaults to '', which is a noop.
• useRequestCache - Optional Use SVG request cache. Defaults to true.
• 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.

Example

<ReactSVG
  afterInjection={(svg) => {
    console.log(svg)
  }}
  beforeInjection={(svg) => {
    svg.classList.add('svg-class-name')
    svg.setAttribute('style', 'width: 200px')
  }}
  className="wrapper-class-name"
  desc="Description"
  evalScripts="always"
  fallback={() => <span>Error!</span>}
  httpRequestWithCredentials={true}
  loading={() => <span>Loading</span>}
  onClick={() => {
    console.log('wrapper onClick')
  }}
  onError={(error) => {
    console.error(error)
  }}
  renumerateIRIElements={false}
  src="svg.svg"
  title="Title"
  useRequestCache={false}
  wrapper="span"
