GOV.UK Navigation Helpers

This is a gem to share code between GOV.UK frontends.

** It should not be used anymore ***

This gem was a temporary solution to the problem of sharing code used to generate the input to components. Since the components can now be built into the govuk_publishing_components gem, it is no longer necessary.

Nomenclature

  • content item: An object returned by the content store

Technical documentation

These helpers format data from the content store for use with GOV.UK Components.

Installation

Add this line to your application's Gemfile:

gem 'govuk_navigation_helpers', '~> VERSION'

And then execute:

$ bundle

Configuration

This gem allows the configuration of:

  • an error handler class (e.g. Airbrake), that implements a notify method which takes an exception object (by default, it prints the exception to stdout when not configured);
  • a statsd client - when not configured, it does not do anything. This client should implement increment(metric) and time(metric, &block).

Usage

Get the JSON representation of a page and initialise the helper:

def some_controller_method
  content_item = Services.content_store.content_item("/register-to-vote")
  @navigation = GovukNavigationHelpers::NavigationHelper.new(content_item)
end

Render the component:

<%= render partial: 'govuk_component/breadcrumbs', locals: @navigation.breadcrumbs %>
<%= render partial: 'govuk_component/related_items', locals: @navigation.related_items %>

Running the test suite

bundle exec rake
