Lookbook is a UI development environment for Ruby on Rails applications, implemented as a Rails Engine gem. It combines a component browser and preview system with an integrated Markdown documentation engine for building modular UIs with ViewComponent, Phlex, and ActionView partials.
Use cases
- browse and preview Rails UI components in isolation
- build a living styleguide for a Rails app
- document ViewComponent components with live preview embeds
- test responsive component behavior in a resizable preview window
- preview Phlex components and ActionView partials
- add editable parameters to component previews
When to choose
- you develop Rails UIs with ViewComponent, Phlex, or partials and want isolated component previews
- your team needs a browsable component styleguide with integrated docs
- you want a drop-in replacement for ViewComponent preview classes with no changes to existing previews
When to avoid
- your project is not a Ruby on Rails application
- you need a general-purpose design tool or static site styleguide outside Rails
- you only need simple CSS styling without component previewing
