Why use ViewComponents over standard Rails partials?

ViewComponents offer better encapsulation, faster rendering, and are easier to test in isolation as plain Ruby objects compared to traditional global-scope partials.

What is view_component-contrib?

It is a set of extensions by Evil Martians that adds advanced features like the Style Variants DSL, dry-initializer support, and improved base classes to ViewComponent.

How does this skill handle Rails helpers inside components?

It enforces the best practice of prefixing Rails helpers with 'helpers.' (e.g., helpers.link_to) to ensure they resolve correctly within the component context.

Does this skill support Lookbook for UI previews?

Yes, it includes specific patterns for creating Lookbook previews, allowing you to visualize and interact with your components in a dedicated sandbox.

About

This skill empowers developers to transition from traditional Rails partials to a robust, object-oriented UI architecture using ViewComponent and view_component-contrib. It provides specialized guidance on implementing complex UI patterns like slots, style variants via a DSL, and Lookbook previews, ensuring components are encapsulated, testable, and maintainable. By enforcing best practices—such as proper helper usage and SVG management—it streamlines the development of high-quality, reusable frontend components within Ruby on Rails applications.

Key Features
