Run the provided generator to create a new ViewComponent with slot-based composition, Lookbook previews, and RSpec tests. This produces boilerplate files that enforce a consistent component API and robust test coverage automatically.

Slot-based composition in ViewComponent allows you to define named content areas within a component for building reusable UI elements. Use slots to standardize complex UI structures like cards, modals, and tables across your Rails application.

Yes, you need a Rails project with ViewComponent, RSpec, and Lookbook already configured. The generator relies on this existing setup to enforce a strong component API, generate previews, and provide automated test coverage.

The best way to standardize UI components like cards and modals in a Rails app is to use ViewComponent with slot-based composition and SOLID design principles. This approach enforces a consistent API and includes Lookbook previews for documentation.

Lookbook previews work for Rails ViewComponents by rendering isolated component instances with predefined parameters for documentation. This allows developers to visualize and test component states and slot usage directly within the development environment.

You should use RSpec for testing ViewComponents to ensure robust test coverage of component APIs and slot behavior. RSpec provides the testing framework required by this setup to validate standardized UI elements and prevent regressions across Rails apps.
