How to display svg icons(.svg files) in UI using React Component?

There are two ways I want to show you.

The first one is just a simple import of the required SVG.

import MyImageSvg from '../../path/to.svg';

Just remember to use a loader for e.g. Webpack:

 {
     test: /\.(ttf|eot|svg|woff(2)?)(\?[a-z0-9=&.]+)?$/,
     include: [Path.join(__dirname, "src/assets")],
     loader: "file-loader?name=assets/[name].[ext]"
 }

Another (and more elegant way) is that you can define an SVG icon sprite and use a component to fetch the correct sprite of the SVG. For example:

import React from "react";
import Icons from "../../assets/icons/icons.svg"; // Path to your icons.svg
import PropTypes from 'prop-types';

const Icon = ({ name, color, size }) => (
  <svg className={`icon icon-${name}`} fill={color} width={size} height={size}>
    <use xlinkHref={`${Icons}#icon-${name}`} />
  </svg>
);

Icon.propTypes = {
  name: PropTypes.string.isRequired,
  color: PropTypes.string,
  size: PropTypes.number
};

export default Icon;

The icon sprite (icons.svg) can be defined as:

<svg xmlns="http://www.w3.org/2000/svg" style="display: none;">

    <symbol id="icon-account-group" viewBox="0 0 512 512">
      <path d="m256 301l0-41c7-7 19-24 21-60 10-5 16-16 16-30 0-12-4-22-12-28 7-13 18-37 12-60-7-28-48-39-81-39-29 0-65 8-77 30-12-1-20 2-26 9-15 16-8 46-4 62 1 2 2 4 2 5l0 42c0 41 24 63 42 71l0 39c-8 3-17 7-26 10-56 20-104 37-112 64-11 31-11 102-11 105 0 6 5 11 11 11l384 0c6 0 10-5 10-11 0-3 0-74-10-105-11-31-69-48-139-74z m-235 168c1-20 3-66 10-88 5-16 57-35 99-50 12-4 23-8 34-12 4-2 7-6 7-10l0-54c0-4-3-9-8-10-1 0-35-12-35-54l0-42c0-3-1-5-2-11-2-8-9-34-2-41 3-4 11-3 15-2 6 1 11-2 13-8 3-13 29-22 60-22 31 0 57 9 60 22 5 17-6 37-11 48-3 6-5 10-5 14 0 5 5 10 11 10 3 0 5 6 5 11 0 4-2 11-5 11-6 0-11 4-11 10 0 43-16 55-16 55-3 2-5 6-5 9l0 54c0 4 2 8 7 10 51 19 125 41 132 62 8 22 9 68 10 88l-363 0z m480-94c-8-25-49-51-138-84l0-20c7-7 19-25 21-61 4-2 7-5 10-9 4-5 6-13 6-20 0-13-5-23-13-28 7-15 19-41 13-64-4-15-21-31-40-39-19-7-38-6-54 5-5 3-6 10-3 15 3 4 10 6 15 3 12-9 25-6 34-3 15 6 25 18 27 24 4 17-6 40-12 52-3 6-4 10-4 13 0 3 1 6 3 8 2 2 4 3 7 3 4 0 6 6 6 11 0 3-1 6-3 8-1 2-2 2-3 2-6 0-10 5-10 11 0 43-17 55-17 55-3 2-5 5-5 9l0 32c0 4 3 8 7 10 83 31 127 56 133 73 7 22 9 68 10 88l-43 0c-6 0-11 5-11 11 0 6 5 11 11 11l53 0c6 0 11-5 11-11 0-3 0-74-11-105z"/>

You can define your own icon sprite on http://fontastic.me/ for free.

And the usage: <Icon name="arrow-down" color="#FFFFFF" size={35} />

And possible add some simple styling for using the icons everywhere:

[class^="icon-"], [class*=" icon-"] {
    display: inline-block;
    vertical-align: middle;
}

For some reasons above mentioned approaches did not work for me, before I followed the advice to add .default like this:

<div>
  <img src={require('../../mySvgImage.svg').default} alt='mySvgImage' />
</div>

If you use create-react-app 2.0 you can now do it like this:

import { ReactComponent as YourSvg } from './your-svg.svg';

And then use it just like you would normally use a component:

const App = () => (
 <div>
   <YourSvg />
 </div>
);

Note that the new name must be capitalized, or else React won't recognize it as a component.
