Rails Heroicon ci

Ruby on Rails views helper for the awesome heroicons by Steve Schoger. To see all the icons visit heroicons.

The latest version of this gem is built with heroicons v2.0.16 (292 icons).

This gem has no official affiliation with Tailwind Labs, yet.

Installation

Add this line to your application's Gemfile:

gem "rails_heroicon"

And then execute:

bundle install

Or install it yourself as:

gem install rails_heroicon

Usage

After installing the gem, call <%= heroicon "user" %> on your erb template. The first argument is the icon name. All the icons are listed here.

This will generate the following html:

<svg
  xmlns="http://www.w3.org/2000/svg"
  aria-hidden="true"
  width="24"
  height="24"
  viewBox="0 0 24 24"
  fill="none"
  stroke="currentColor"
  stroke-width="1.5"
  version="1.1"
>
  <path
    d="M16 7C16 9.20914 14.2091 11 12 11C9.79086 11 8 9.20914 8 7C8 4.79086 9.79086 3 12 3C14.2091 3 16 4.79086 16 7Z"
    stroke-width="2"
    stroke-linecap="round"
    stroke-linejoin="round"
  />
  <path
    d="M12 14C8.13401 14 5 17.134 5 21H19C19 17.134 15.866 14 12 14Z"
    stroke-width="2"
    stroke-linecap="round"
    stroke-linejoin="round"
  />
</svg>

Note: Indentation is for readability purpose.

Variant

rails_heroicon provides 3 variants, outline, solid, and mini, outline being the default.

To change the variant <%= heroicon "user", variant: "solid" %>.

HTML attributes

Any html and eruby attribute is supported, for eg:

<%= heroicon "user", class: "text-gray-500", aria: { label: "user-icon" } %>

Handling the size of the icon

Normally, if you're just using vanilla heroicons with Tailwind CSS, you'd add w-5 h-5 as classes on the svg element. With rails_heroicon, you just need to set the size attribute on the helper method.

<%= heroicon "user", size: 20 %>

If the variant is set as outline or solid, size automatically defaults to 24, and if the variant is set as mini, size automatically defaults to 20. However, this can be over-written with the size attribute.

Accessibility

rails_heroicon automatically sets aria-hidden="true" if aria-label is not set, and if aria-label is set, then role="img" is set.

Tooltip

You can provide tooltips on hover if you pass in a title option. Anything passed into the title option will be rendered inside of a <title> tag within the rendered SVG, which modern browsers will lean on to display a tooltip on hover.
