SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Rails apps often re-implement UI logic across views. ViewComponents provide a structured, testable way to encapsulate UI, reducing duplication and improving maintainability.

Core Features & Use Cases

Encapsulated components with dedicated Ruby classes and templates.
Slots and patterns like renders_one, renders_many for flexible composition.
Reusable building blocks for badges, cards, tables, modals, and presenters.
Built-in testability with component specs using RSpec and Capybara.

Quick Start

Install the ViewComponent gem and generate your first component to begin building reusable UI blocks.

FAQPage Schema

How do I build reusable UI components in Rails to reduce view duplication?▼

Build reusable UI components in Rails using ViewComponent to encapsulate Ruby classes and templates, extracting complex partials into structured building blocks like cards and modals to reduce duplication.

When should I extract Rails partials into ViewComponents instead of helpers?▼

Extract Rails partials into ViewComponents when you need consistent, testable UI across views, especially for complex elements like tables, badges, and modals that require dedicated Ruby classes and templates.

How do I use renders_one and renders_many for flexible component composition in Rails?▼

Use renders_one and renders_many slot patterns in ViewComponent to enable flexible UI composition, allowing Rails components to accept multiple configurable content blocks for building complex cards and presenters.

Can I test ViewComponent UI elements with RSpec and Capybara in Rails?▼

Test ViewComponent UI elements with RSpec and Capybara by writing component specs that validate rendered output directly, ensuring UI components behave consistently without requiring full Rails integration tests.

Do I need the ViewComponent gem to build testable UI patterns in Ruby on Rails?▼

You need the ViewComponent gem, Ruby, Rails, and RSpec to build testable UI patterns, as the gem provides the framework for encapsulating Ruby classes and templates into reusable, structured UI blocks.
