Middleman Inline SVG

A Middleman extension embed SVG documents in your Middleman views.

1. Add middleman-inline_svg to your Gemfile and run Bundler:

   gem "middleman-inline_svg"

   bundle install

2. Activate the extension in config.rb:

   activate :inline_svg

middleman-inline_svg provides an inline_svg helper that you can use in your templates. Using it will inline your SVG document directly into the HTML enabling you to style it with CSS and pass in HTML attributes.

Given the following SVG file named heart.svg:

<svg width="24" height="24" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
  <path d="M20.84 4.61a5.5 5.5 0 0 0-7.78 0L12 5.67l-1.06-1.06a5.5 5.5 0 0 0-7.78 7.78l1.06 1.06L12 21.23l7.78-7.78 1.06-1.06a5.5 5.5 0 0 0 0-7.78z"></path>
</svg>

And the following code in a Middleman template:

<%= inline_svg "heart.svg", class: "icon icon--small" %>

Middleman will output the following:

<svg class="icon icon--small" width="24" height="24" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
  <path d="M20.84 4.61a5.5 5.5 0 0 0-7.78 0L12 5.67l-1.06-1.06a5.5 5.5 0 0 0-7.78 7.78l1.06 1.06L12 21.23l7.78-7.78 1.06-1.06a5.5 5.5 0 0 0 0-7.78z"></path>
</svg>

It's possible to specify a title for the SVG. And any other options passed will be rendered as attributes on the <svg> element. Adding a title to your SVG will improve accessibility.

<%= inline_svg(
  "heart.svg",
  role: "img",
  title: "Like this comment",
) %>

<svg role="img" width="24" height="24" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
  <title>Like this comment</title>
  <path d="M20.84 4.61a5.5 5.5 0 0 0-7.78 0L12 5.67l-1.06-1.06a5.5 5.5 0 0 0-7.78 7.78l1.06 1.06L12 21.23l7.78-7.78 1.06-1.06a5.5 5.5 0 0 0 0-7.78z"></path>
</svg>

Underscores are translated into hyphens in the output.

<%= inline_svg(
  "heart.svg",
  aria_hidden: true,
) %>

<svg aria-hidden="true" width="24" height="24" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
  <title>Like this comment</title>
  <path d="M20.84 4.61a5.5 5.5 0 0 0-7.78 0L12 5.67l-1.06-1.06a5.5 5.5 0 0 0-7.78 7.78l1.06 1.06L12 21.23l7.78-7.78 1.06-1.06a5.5 5.5 0 0 0 0-7.78z"></path>
</svg>

You can configure the default attributes/title in the Middleman config.rb file when the extension is activated:

activate :inline_svg do |config|
  config.defaults = {
    role: img,
  }
end
