SVG sprite in external file

I'm using an icon system for my app with SVG Sprite, created by IcoMoon App.
In index.html I have now something like this:

<html>
<head>...</head>
<body>
<svg display="none" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="752" height="80" viewBox="0 0 752 80">
<defs>
<g id="icon-home">
<path class="path1" d="M32 18.451l-16-12.42-16 12.42v-5.064l16-12.42 16 12.42zM28 18v12h-8v-8h-8v8h-8v-12l12-9z" />
</g>
<g id="icon-camera">
<path class="path1" d="M9.5 19c0 3.59 2.91 6.5 6.5 6.5s6.5-2.91 6.5-6.5-2.91-6.5-6.5-6.5-6.5 2.91-6.5 6.5zM30 8h-7c-0.5-2-1-4-3-4h-8c-2 0-2.5 2-3 4h-7c-1.1 0-2 0.9-2 2v18c0 1.1 0.9 2 2 2h28c1.1 0 2-0.9 2-2v-18c0-1.1-0.9-2-2-2zM16 27.875c-4.902 0-8.875-3.973-8.875-8.875 0-4.902 3.973-8.875 8.875-8.875 4.902 0 8.875 3.973 8.875 8.875 0 4.902-3.973 8.875-8.875 8.875zM30 14h-4v-2h4v2z" />
</g>
</defs>
</svg>
...some html code...
<!-- an image -->
<svg class="icon" viewBox="0 0 32 32"><use xlink:href="#icon-home"></use></svg>
</body>
<html>


I need to move the svg sprite in a file and then include it as an external resource.
How can I do this?

Answer Source

Try this:

Create a svg file, sprites.svg

Place the following in it:

<svg  version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" >
        <path id="icon-home" class="path1" d="M32 18.451l-16-12.42-16 12.42v-5.064l16-12.42 16 12.42zM28 18v12h-8v-8h-8v8h-8v-12l12-9z" />
        <path id="icon-camera" class="path1" d="M9.5 19c0 3.59 2.91 6.5 6.5 6.5s6.5-2.91 6.5-6.5-2.91-6.5-6.5-6.5-6.5 2.91-6.5 6.5zM30 8h-7c-0.5-2-1-4-3-4h-8c-2 0-2.5 2-3 4h-7c-1.1 0-2 0.9-2 2v18c0 1.1 0.9 2 2 2h28c1.1 0 2-0.9 2-2v-18c0-1.1-0.9-2-2-2zM16 27.875c-4.902 0-8.875-3.973-8.875-8.875 0-4.902 3.973-8.875 8.875-8.875 4.902 0 8.875 3.973 8.875 8.875 0 4.902-3.973 8.875-8.875 8.875zM30 14h-4v-2h4v2z" />
</svg>

Then whenever you want to include in a use element

    <svg class="icon" viewBox="0 0 32 32"><use xlink:href="sprites.svg#icon-home"></use></svg>

(At this time, Internet Explorer has a problem with this. IE would need a different approach. If you want, I can also show what's needed for IE)

EDIT - Cross browser support: Place SVG sprite elements in an XML file and call them into a defs element.

XML file, named sprites.xml:

<?xml version="1.0" encoding="UTF-8"?>
<SPRITES xmlns="http://www.w3.org/2000/svg">
<path id="iconHome"  d="M32 18.451l-16-12.42-16 12.42v-5.064l16-12.42 16 12.42zM28 18v12h-8v-8h-8v8h-8v-12l12-9z" />
<path id="iconCamera"  d="M9.5 19c0 3.59 2.91 6.5 6.5 6.5s6.5-2.91 6.5-6.5-2.91-6.5-6.5-6.5-6.5 2.91-6.5 6.5zM30 8h-7c-0.5-2-1-4-3-4h-8c-2 0-2.5 2-3 4h-7c-1.1 0-2 0.9-2 2v18c0 1.1 0.9 2 2 2h28c1.1 0 2-0.9 2-2v-18c0-1.1-0.9-2-2-2zM16 27.875c-4.902 0-8.875-3.973-8.875-8.875 0-4.902 3.973-8.875 8.875-8.875 4.902 0 8.875 3.973 8.875 8.875 0 4.902-3.973 8.875-8.875 8.875zM30 14h-4v-2h4v2z" />
</SPRITES>

An example HTML file with Javascript to propagate the defs element.

<!DOCTYPE HTML>
<html>
<head>
  <title>Sprites</title>
</head>
<body onLoad=loadSprites()>
<svg id=mySVG width="400" height="400">
<defs id="spriteDefs" />
    <use xlink:href="#iconHome" transform="translate(100 100)" />
    <use xlink:href="#iconHome" transform="translate(200 100)" />
    <use xlink:href="#iconHome" transform="translate(300 100)" />
    <use xlink:href="#iconCamera" transform="translate(100 200)" />
    <use xlink:href="#iconCamera" transform="translate(200 200)" />
    <use xlink:href="#iconCamera" transform="translate(300 200)" />
    <use xlink:href="#iconHome" transform="translate(200 300)" />
</svg>
<script>
function loadSprites()
{
   	var xmlFile="sprites.xml"
	var loadXML = new XMLHttpRequest;
	loadXML.onload = callback;
	loadXML.open("GET", xmlFile, true);
	loadXML.send();
	function callback()
	{
		//---responseText---
		var xmlString=loadXML.responseText
		//---DOMParser---
		var parser = new DOMParser();
	    var mySpritesDoc=parser.parseFromString(xmlString,"text/xml").documentElement ;
        var addSprites=mySpritesDoc.childNodes
        for(var k=0;k<addSprites.length;k++)
        {
           var sprite=addSprites.item(k).cloneNode(true)
           document.getElementById("spriteDefs").appendChild(sprite)
        }
    }
}
</script>
</body>
</html>
