Is there any way to output the actual source code from an SVG asset in Craft?

Rather than linking to it, I would like to embed the code in the page.

I tried a twig include, but I cannot include files outside the templates folder.

Thanks!

Check out my plugin Inlin, I made it exactly for this. :)

What about using <use> (see css-tricks article) to reference the SVG from the template instead of embedding the actual code?

That's what I do for SVGs currently. Difference is that I don't use Craft assets for this, but have a grunt task that concatenates all SVGs from a folder into one single SVG file with multiple symbols. Then I use a macro that outputs the SVG tag. Just modified that code to make it work with Craft assets, all you need to do is to add an assets meta field to your asset with a handle symbol (or similar) to reference the right shape.

{% macro svg(svgAssetModel, cssClasses) %}

    <svg class="{{ cssClasses }}" title="{{ svgAssetModel.title }}">
        <use xlink:href="{{ svgAssetModel.url }}#{{ svgAssetModel.symbol }}"></use>
    </svg>

{% endmacro %}

{{ macros.svg(entry.svg.first, 'big-blue-symbol') }}

  • Looks like a great approach for multiple icons, but in my limited use case I actually needed to just embed one svg. – mjr Aug 22 '14 at 14:47

    @mjr use the html without the macro. Now you install and update a plugin for that one SVG? I'm confused... – carlcs Aug 22 '14 at 14:52
  • @carlcs Your approach creates one (!) request for the svg-file. :) The whole point of inlining is reducing requests. – André Elvan Aug 22 '14 at 15:57
  • @aelvan ouuups.. re-read the question and noticed that mjr actually asks on how to inline the code. Without inlining you'd benefit from having the file cached though :) – carlcs Aug 22 '14 at 16:03
  • But! We don't know how large that files is, @aelvan. Maybe it's a 13MB city map... X) – carlcs Aug 22 '14 at 16:13

    @carlcs Yeah, there are trade-offs with both solutions. I'm not sure about this, but I also think it's not possible to style svg elements inside the element you "use", with this approach? If your symbol contains three paths, and you want to control the fill of these individually? Might be something to check out. – André Elvan Aug 22 '14 at 16:15
  • @carlcs Haha, true, we don't know if inlining is a good idea in this case. But I trust mjr to know what he's doing. ;) – André Elvan Aug 22 '14 at 16:16

There is now a function called svg in Craft itself: https://docs.craftcms.com/v3/dev/functions.html#svg
