Use icons from heroicons.com in your Rails applications.

Add this line to your application's Gemfile:

gem 'rails_heroicons', '~> 0.6.0'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_heroicons

Before you can add an icon, you need to find the icons name. Refer to heroicons.com for a full list of icon names.

This gem provides you with a single new Rails helper called heroicon. You can use heroicon in your templates to add an icon:

<%= heroicon('user') %>

This will embed the following HTML to render the icon:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 20" fill="currentColor">
  <path fill-rule="evenodd" d="M10 9a3 3 0 100-6 3 3 0 000 6zm-7 9a7 7 0 1114 0H3z" clip-rule="evenodd"/>
</svg>

You can add a class to the SVG to target the icon for styling. This is done using the class_name option:

<%= heroicon('user', class_name: 'icon icon-large') %>

This will embed the following HTML to render the icon:

<svg class="icon icon-large" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 20" fill="currentColor">
  <path fill-rule="evenodd" d="M10 9a3 3 0 100-6 3 3 0 000 6zm-7 9a7 7 0 1114 0H3z" clip-rule="evenodd"/>
</svg>

The official Heroicons icons support two different styles. On heroicons.com they refer to these as medium and small. Medium icons are outlined icons with no fill. Small icons are solid icons with a solid fill.

Behind the scenes, the offical Heroicon repo refers to medium icons as outlined icons. Small icons are referred to as solid icons. That naming convention makes more sense to me than medium vs small as these icons could be resized with CSS anyway.

Anyways...

You can use the style option to customize the icon style. There are two valid values:

• :solid - This is the default value. This render a solid icon (referred to as small on heroicons.com)
• :outline - This will render an outlined icon (referred to as medium on heroicons.com)

You can use style to switch to and outlined version of any icon:

<%= heroicon('user', style: :outline, class_name: 'icon icon-large') %>

This will embed the following HTML to render the icon:

<svg class="icon icon-large" xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor">
  <path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M16 7a4 4 0 11-8 0 4 4 0 018 0zM12 14a7 7 0 00-7 7h14a7 7 0 00-7-7z"/>
