Parameters

Configure Storybook addons with parameters. Global parameters are defined in .storybook/preview.js - this is how the Storybook Rails application url.

Parameters can be defined for all stories with the parameters method:

# test/components/stories/header_component_stories.rb
class HeaderComponentStories < ViewComponent::Storybook::Stories
  # disable a11y for all stories in this class
  parameters(a11y: { disable: true ))

  def h1
    render HeaderComponent.new("h1") do
      "Hello World!"
    end 
end

Restricting parameters to certain stories

Parameters specified at the Stories and Story level are merged in that order. the paameters method suports only and except options in the same format as the controls method. For example disable the a11y addon for all stories and enable it for one:

# test/components/stories/header_component_stories.rb
class HeaderComponentStories < ViewComponent::Storybook::Stories
  # disable a11y for all stories in this class
  parameters(a11y: { disable: true ))

  def h1
    render HeaderComponent.new("h1") do
      "Hello World!"
    end 

  
  parameters(a11y: { disable: false ), only: :h2)
  
  def h2
    render HeaderComponent.new("h2") do
      "How are you?"
    end 
  end
end
