Embedding SVG into ReactJS

Update 2016-05-27

As of React v15, support for SVG in React is (close to?) 100% parity with current browser support for SVG (source). You just need to apply some syntax transformations to make it JSX compatible, like you already have to do for HTML (class → className, style="color: purple" → style={{color: 'purple'}}). For any namespaced (colon-separated) attribute, e.g. xlink:href, remove the : and capitalize the second part of the attribute, e.g. xlinkHref. Here’s an example of an svg with <defs>, <use>, and inline styles:

function SvgWithXlink (props) {    return (        <svg            width="100%"            height="100%"            xmlns="http://www.w3.org/2000/svg"            xmlnsXlink="http://www.w3.org/1999/xlink"        >            <style>                { `.classA { fill:${props.fill} }` }            </style>            <defs>                <g id="Port">                    <circle style={{fill:'inherit'}} r="10"/>                </g>            </defs>            <text y="15">black</text>            <use x="70" y="10" xlinkHref="#Port" />            <text y="35">{ props.fill }</text>            <use x="70" y="30" xlinkHref="#Port" className="classA"/>            <text y="55">blue</text>            <use x="0" y="50" xlinkHref="#Port" style={{fill:'blue'}}/>        </svg>    );}

For more details on specific support, check the docs’ list of supported SVG attributes. And here’s the (now closed) GitHub issue that tracked support for namespaced SVG attributes.

You can do a simple SVG embed without having to use dangerouslySetInnerHTML by just stripping the namespace attributes. For example, this works:

        render: function() {            return (                <svg viewBox="0 0 120 120">                    <circle cx="60" cy="60" r="50"/>                </svg>            );        }

At which point you can think about adding props like fill, or whatever else might be useful to configure.

If you just have a static svg string you want to include, you can use dangerouslySetInnerHTML:

render: function() {    return <span dangerouslySetInnerHTML={{__html: "<svg>...</svg>"}} />;}

and React will include the markup directly without processing it at all.

According to a react developer, you dont need the namespace xmlns. If you need the attribute xlink:href you can use xlinkHref from react 0.14

Example

Icon = (props) => {  return <svg className="icon">    <use xlinkHref={ '#' + props.name }></use>  </svg>;}
