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
