react-svg-unique-id

SVG processors like SVGO optimize SVG ids which often results in duplicated ids across multiple SVGs. This library tries to fix that by replacing all children ids and id references (#id, url(#id)) in SVG tags with unique generated ids like ___SVG_ID__10__0___.

How to install

yarn add react-svg-unique-id
# or
npm install react-svg-unique-id

Usage

import * as React from 'react'
import { SVGUniqueID } from 'react-svg-unique-id'

export const SVG1 = () => (
  <SVGUniqueID>
    <svg width="100%" height="100%" viewBox="0 0 60 64">
      <defs>
        <linearGradient id="prefix__bga" /> // prefix__bga => ___SVG_ID__0__0___
      </defs>
      <g fillRule="nonzero" fill="none">
        <use xlinkHref="#prefix__bga" /> // #prefix__bga => #___SVG_ID__0__0___
        <path fill="url(#prefix__bga)" /> // url(#prefix__bga) => "url(#___SVG_ID__0__0___)
      </g>
    </svg>
  </SVGUniqueID>
)

export const SVG2 = () => (
  <SVGUniqueID>
    <svg width="100%" height="100%" viewBox="0 0 60 64">
      <defs>
        <linearGradient id="prefix__bga" /> // prefix__bga => ___SVG_ID__1__0___
      </defs>
      <g fillRule="nonzero" fill="none">
        <use xlinkHref="#prefix__bga" /> // #prefix__bga => #___SVG_ID__1__0___
        <path fill="url(#prefix__bga)" /> // url(#prefix__bga) => url(#___SVG_ID__1__0___)
      </g>
    </svg>
  </SVGUniqueID>
)

If both of these SVGs were not wrapped in SVGUniqueID component there would be an id collision since two html elements would have prefix__bga as thier id.
