Lucide Icons in Rails
Render Lucide icons as inline SVGs via the lucide-rails gem. Icons use currentColor so they inherit text color automatically.
When To Use This Skill
- Adding icons to a Rails view (buttons, nav, badges, empty states)
- Choosing the right Lucide icon name for a UI element
- Making icons accessible (decorative vs interactive)
- Styling or sizing SVG icons with CSS
Philosophy
- Icons are decoration until they aren't — Decorative icons need no label. Interactive icons (buttons, links) MUST have accessible text.
- Size intentionally — Always pass
size:. The default 24px is too large for most inline contexts. - Let CSS handle color — Icons inherit
currentColor. Style the parent, not the SVG. - Use the helper, never raw SVGs —
lucide_iconkeeps icons consistent, cacheable, and updatable. - kebab-case names only — It's
"chevron-right", never"chevronRight"or"ChevronRight".
