• Ruby - click here for the exact version
• Bundler
• Rails
• HAML

Installation

Within your rails application, add the below to your Gemfile.

gem 'pugin'

Usage

This gem's main function is to expose front-end components and assets to the host application's asset pipeline.

Once you add the gem to your Gemfile run:

bundle install

Now all of the view components should be available within your host application.

Example

<%= render partial: 'pugin/components/status' %>

Adding the Parliamentary layout

Add the following line into the application controller within your host application

layout 'pugin/layouts/pugin'

Including rel-alternate links

When rendering using the Parliamentary layout, if you'd like to document rel-alternates like so:

<link rel="alternate" type="application/rdf+json" href="https://api.example.com/some/url" />
<link rel="alternate" type="application/rdf+xml" href="https://api.example.com/some/other/url" />

You can do so automatically by setting Pugin.alternates.

Example

Within your controller:

alternates = [
  { type: 'application/rdf+json', href: 'https://api.example.com/some/url' },
  { type: 'application/rdf+xml', href: 'https://api.example.com/some/other/url' }
]

Pugin.alternates = alternates
