ViewComponent is a Ruby framework for building reusable, testable, and encapsulated view components in Ruby on Rails, inspired by React and the presenter pattern. As of version 4 it is feature-complete and in Long-Term Support, with recent releases adding experimental component-level caching support.

Use cases

• build reusable UI components in Rails
• unit test Rails view templates
• replace partials with encapsulated components
• consolidate view logic scattered across helpers and models
• render view objects from controllers
• speed up view testing compared to controller tests

When to choose

• you maintain a Rails app with templates reused across views
• you want component-style architecture (React-like) in Rails ERB
• you need fast, direct unit tests for view markup
• your views have heavy embedded Ruby logic that needs encapsulation

When to avoid

• you are not using Ruby on Rails
• you want a full frontend framework with client-side interactivity
• you need a JavaScript component system like React or Vue
• you prefer simple partials for one-off templates
