heroicons-ruby

A simple Heroicons helper for Ruby on Rails.

bundle add heroicons-ruby

Usage

<!-- Render plain Heroicon SVG -->
<%= heroicon "arrow-right" %>

<!-- Use non-default variant -->
<%= heroicon "arrow-right", variant: :mini %>

<!-- Provide HTML attributes for the rendered SVG -->
<%= heroicon "arrow-right", class: "h-4 w-4", fill: "none" %>

Configuration

Valid variant values are %i[micro mini solid outline]. The default variant is solid however that default can be changed using:

# config/initializers/heroicons.rb
Heroicons.configure do |config|
  config.variant = :mini
end

If you would like to specify default HTML attributes (eg. class="h-4 w-4") for a given variant, you can configure that like so:

# config/initializers/heroicons.rb
Heroicons.configure do |config|
  config.attributes[:mini] = { class: "h-4 w-4" }
end

Rationale

Don't libraries already exist for this? Why make another?

The key differences between heroicons-ruby and others are:

• Can be used without Rails (no need to pull in entire Rails dependency if not needed)
• Renders exact Heroicons SVG identical to those found in the official repo. No transformations / differences from the official SVGs to worry about.
  • This also makes it very easy to keep this library up to date. On each new Heroicons release, all that needs to be done is a copy-paste of the official icons to the /icons folder.
• Very thin API wrapper around <svg> making it easy and concise to configure HTML attributes.

  <%= heroicon "check", class: "h-4 w-4" %>

• This library is used in production in numerous applications and given that I use TailwindCSS in all my projects, I'm highly incentivized to keep things up to date here. I can also guarantee that semantic versioning will be followed to ensure a stable API.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
