ViewComponent is far from a novel idea! Popular implementations of view components in Ruby include, but are not limited to:
ViewComponent does not include support for validations. However, it can be added by using
class ExampleComponent < ViewComponent::Base include ActiveModel::Validations # Requires that a content block be passed to the component validate :content, presence: true def before_render validate! end end
Note: Using validations in this manner can lead to runtime exceptions. Use them wisely.
