PageStructuredData

Use this gem to churn out meta tags for your rails webpages. This also renders meta tags for the following:

1. Page <title> tag with proper hyphenation when used with breadcrumbs
2. Basic <meta> tags
3. Twitter meta tags
4. Open graph meta tags
5. Google Schema JSON-LD <script> tags

Add this line to your application's Gemfile:

gem "page_structured_data"

And then execute:

$ bundle

Or install it yourself as:

$ gem install page_structured_data

Add the following in your layout to include the basic meta tags by default

<%= render 'page_structured_data/meta_tags', page: @page_meta, 
    default_image_url: image_url('<path_to_default_image>') %>

Note: This doesn't include csrf or any other security or viewport related meta tags.

In your views, please define the @page_meta as follows

<% @page_meta = PageStructuredData::Page.new(title: 'Home', extra_title: "Official Page",
        description: 'Welcome to my Page') %>

The instance variable will be used in the layout to create proper meta tags. Most attributes are self explanatory. extra_title is used to append to the title.

Configure the application wide settings as follows:

# config/initializers/page_structured_data.rb
Rails.application.config.after_initialize do
  PageStructuredData.config do |config|
    config.base_app_name = 'AwesomestApp' # or use any application constant as this is called after_initialize
  end
end

Create a list of breadcrumbs like this:

<% breadcrumb = PageStructuredData::Breadcrumbs.new(hierarchy: [{ title: 'Resources', href: resources_url }, { title: 'Articles', href: resources_articles_url }]) %>

And include it in the Page.new as:

<% @page_meta = PageStructuredData::Page.new(title: 'Home', extra_title: "Official Page",
        description: 'Welcome to my Page', breadcrumb: breadcrumb) %>

This will create a JSON+LD breadcrumbs similar to Breadcrumbs

Currently this gem supports the following page types:

• BlogPosting
• NewsArticle

To use these, it is similar to breadcrumbs: include them in Page.new and it the json+ld will be automatically included.

<% article_page_type = PageStructuredData::PageTypes::BlogPosting.new(headline: @article.title, published_at: @article.published_at,
        updated_at: @article.updated_at, authors: [name: @article.authors.first.name, url: @article.authors.first.website],
        images: [main_app.url_for(@article.cover_image.variant(:standard))]) %>
<% @page_meta = PageStructuredData::Page.new(title: 'Home', extra_title: "Official Page",
                                             description: 'Welcome to my Page', page_type: article_page_type) %>

Just replace BlogPosting class with the other type for other page types.
