Shoelace Rails

The shoelace-rails gem adds useful helper methods for Shoelace.style, the design system.

Compatibility with Shoelace

  • For Shoelace version >= 2.0.0-beta.88, use the gem version 0.4.0 or above.
  • For Shoelace version <= 2.0.0-beta.87, use the gem version 0.3.0.

Installation

Add this line to your application's Gemfile:

gem 'shoelace-rails'

And then execute:

$ bundle install

Additionally, you need to add the following npm packages:

$ yarn add @shoelace-style/shoelace

Set up CSS

Asset Pipeline

Add the following lines to the app/assets/stylesheets/application.css if you need the sprockets gem:

/*
 *= require @shoelace-style/shoelace/dist/themes/light.css
 *= require @shoelace-style/shoelace/dist/themes/dark.css
 */

Webpack & CSS Loader

Add the following lines to the app/packs/entrypoints/application.js if you prefer the webpack and CSS loader:

import "@shoelace-style/shoelace/dist/themes/light.css"
import "@shoelace-style/shoelace/dist/themes/dark.css" // Optional dark mode

Set up Javascript

In this README, it is assumed that you are using a JS bundler such as webpack or esbuild. In order to define all the custome elements, import the shoelace dependency in the entrypoint file:

import "@shoelace-style/shoelace"

That's it!

Shoelace Icons

Shoelace icons are automatically set up to load properly, so you don't need to add any extra code. More specifically,

  • In development, the icons are served by the ActionDispatch::Static middleware, directly from the node_modules/@shoelace-style/shoelace/dist/assets/icons directory.
  • In production, the icon files are automatically copied into the public/assets directory as part of the assets:precompile rake task.

View Helpers

As explained above, this gem provides drop-in replacements to Rails view helpers.

Form Helpers

The sl_form_with or sl_form_for method could be used to generate a form with the Shoelace components:

<%= sl_form_for @user do |form| %>
  <%  # Text input: https://shoelace.style/components/input %>
  <%= form.text_field :name %>
  <%= form.password_field :password, placeholder: "Password Toggle", 'toggle-password': true %>

  <%  # Radio buttons: https://shoelace.style/components/color-picker %>
  <%= form.color_field :color %>

  <%  # Radio buttons: https://shoelace.style/components/radio %>
  <%= form.collection_radio_buttons :status, { id_1: "Option 1", id_2: "Option 2", id_3: "Option 3" }, :first, :last %>

  <%  # Select: https://shoelace.style/components/select %>
  <%= form.collection_select :tag, { id_1: "Option 1", id_2: "Option 2", id_3: "Option 3" }, :first, :last, {}, { placeholder: "Select one" } %>

  <%= form.submit %>
<% end %>

And this code will produce:

<form class="new_user" id="new_user" data-remote="true" action="/" accept-charset="UTF-8" method="post">
  <sl-input label="Name" type="text" name="user[name]" id="user_name"></sl-input>
  <sl-input label="Password" type="password" name="user[password]" id="user_password"></sl-input>
  <sl-color-picker value="#ffffff" name="user[color]" id="user_color"></sl-color-picker>

  <sl-radio-group no-fieldset="true">
    <sl-radio value="id_1" name="user[status]" id="user_status_id_1">Option 1</sl-radio>
    <sl-radio value="id_2" name="user[status]" id="user_status_id_2">Option 2</sl-radio>
    <sl-radio value="id_3" name="user[status]" id="user_status_id_3">Option 3</sl-radio>
  </sl-radio-group>

  <sl-select placeholder="Select one" name="user[tag]" id="user_tag">
    <sl-menu-item value="id_1">Option 1</sl-menu-item>
    <sl-menu-item value="id_2">Option 2</sl-menu-item>
    <sl-menu-item value="id_3">Option 3</sl-menu-item>
  </sl-select>

  <sl-button submit="true" type="primary" data-disable-with="Create User">Create User</sl-button>
</form>

Using the Shoelace FormBuilder with other gems

Sometimes you want to use the Shoelace FormBuilder with other gems, such as ransack. In this case, you can not use the sl_form_for or sl_form_with methods in tandem with ransack, but you can use the Shoelace::FormBuilder with e.g. the search_form_for method:

<%= search_form_for @q, builder: Shoelace::FormBuilder do |form| %>
  ...
<% end %>

Tag Helpers

#sl_avatar_tag

The @sl_avatar_tag method behaves just like the image_tag method.

<%= sl_avatar_tag "/path/to/image.jpg" %>

Will produce:

<sl-avatar image="/path/to/image.jpg"></sl-avatar>

#sl_button_to

The sl_button_to method behaves just like the link_to method. Note that this is slightly different from the built-in button_to method.

Without a block:

<%= sl_button_to "Next Page", "/components?page=2" %>
<sl-button href="/components?page=2">
  Next Page
</sl-button>

With a block:

<%= sl_button_to "/components?page=2" do %>
  Next Page 
<% end %>
<sl-button href="/components?page=2">
 Next Page
</sl-button>

#sl_icon_tag

The sl_icon_tag method takes the name attribute value as the first argument:

<%= sl_icon_tag "apple" %>
<sl-icon name="apple"></sl-icon>
