Overview

An abstract class with the logic for the GraphQL endpoint for a single component to be searchable. Normal components (such as Proposal) can inherit from this class and just add the needed search arguments

Usually something like:

class ProposalFinderHelper < Decidim::Core::ComponentFinderBase
  argument :id, !types.ID, "The ID of the proposal"
end

For an example check decidim-proposals/app/types/decidim/proposals/proposals_type.rb
