Gem example

[Olivier]

Do you have a working example of a gem that leverages Komponent ready for a Rails app.?

[Florent FERRY]

We do not have an example gem which embed components. If you want to wrap your components in a gem you can refer to the additional paths.

[Olivier]

ok mais concrètement où devraient se trouver les composants dans le gem?

/frontend/components
/lib/frontend/components

Pour le moment j'obtiens

my_gem/lib/my_gem.rb:16:in `block in <class:Railtie>': undefined method `root' for #<MyGem::Railtie:0x007f8229fb10c8> (NoMethodError)

avec le code sous additional path dans my_gem.rb

[Florent FERRY]

I think the documentation is wrong about the self, try replacing it with Yastyle.root when using it in your initializers defined in your gem. I should update the readme if it's working for you too.

Getting undefined method `root' for Komponent:Module (NoMethodError) with the following

module Yastyle
  class Railtie < Rails::Railtie
    config.after_initialize do |app|
      app.config.komponent.component_paths.append(Komponent.root.join("frontend/components"))
    end

    initializer "yastyle.action_dispatch" do |app|
      ActiveSupport.on_load :action_controller do
        ActionController::Base.prepend_view_path Komponent.root.join("frontend")
      end
    end

    initializer 'yastyle.autoload', before: :set_autoload_paths do |app|
      app.config.autoload_paths << Komponent.root.join("frontend")
    end

    private

    def self.root
      Pathname.new(File.dirname(__dir__))
    end
  end
end

[Florent FERRY]

Put access modifier and root method inside Yastyle module but outside Railtie class.

[Olivier]

I'm getting this time

There was an error while trying to load the gem 'yastyle'. (Bundler::GemRequireError)
Gem Load Error is: undefined local variable or method `config' for Yastyle:Module

require "yastyle/version"

module Yastyle
  config.after_initialize do |app|
    app.config.komponent.component_paths.append(Komponent.root.join("frontend/components"))
  end

  initializer "yastyle.action_dispatch" do |app|
    ActiveSupport.on_load :action_controller do
      ActionController::Base.prepend_view_path Komponent.root.join("frontend")
    end
  end

  initializer 'yastyle.autoload', before: :set_autoload_paths do |app|
    app.config.autoload_paths << Komponent.root.join("frontend")
  end

  private

  def self.root
    Pathname.new(File.dirname(__dir__))
  end

  class Railtie < Rails::Railtie
  end
end

[Hans Lemuet]

I think what @florentferry meant was:

require "yastyle/version"

module Yastyle
  class Railtie < Rails::Railtie
    config.after_initialize do |app|
      app.config.komponent.component_paths.append(Komponent.root.join("frontend/components"))
    end

    initializer "yastyle.action_dispatch" do |app|
      ActiveSupport.on_load :action_controller do
        ActionController::Base.prepend_view_path Komponent.root.join("frontend")
      end
    end

    initializer 'yastyle.autoload', before: :set_autoload_paths do |app|
      app.config.autoload_paths << Komponent.root.join("frontend")
    end
  end

  private

  def self.root
    Pathname.new(File.dirname(__dir__))
  end
end

@Spone

Getting undefined method `root' for Komponent:Module (NoMethodError)

at app.config.autoload_paths << Komponent.root.join("frontend")

[Hans Lemuet]

Actually, Komponent.root should be Yastyle.root in your case (you have to use the name of your Gem module)

[Hans Lemuet]

Then, put your components in a frontend/components folder, which should be placed in the path returned by your Yastyle.root method.

[Florent FERRY]

Seems this issue been resolved, I closing it. I shoulda merge a PR with an update to readme on how to wrap components in a gem.
