Design System
Comprehensive guide for building, styling, and using components in the frontend.
When to Apply
Reference these guidelines when:
- Working on
.{vue|css|scss}files inpackages/frontend - Adding new components to
packages/frontend/@n8n/design-system - Refactoring styles for Vue components
- Implementing new UI components or features
- Reviewing changes to UI
Rules
- Follow guidelines in
packages/frontend/@n8n/design-system/src/styleguide/*.mdx - ALWAYS use CSS variables for styles from
packages/frontend/@n8n/design-system/src/css/_tokens.scssorpackages/frontend/@n8n/design-system/src/css/_primitives.scss. Use hard-coded values only when no suitable tokens. - ALWAYS prefer using existing components from
packages/frontend/@n8n/design-system/src/components. Prefer components that aren't marked@deprecated. - Use
light-dark()when alternating colors for ligh/dark mode - If you need to add hover/active alpha behavior to solid components, prefer
color-mix()with explicit percentages. - When working with animations or transitions, ALWAYS prefer using mixins from
packages/frontend/@n8n/design-system/src/css/mixins/motion.scss - When reviewing animations, follow the guides in
rules/web-animation-guidelines.md - When reviewing UI changes or adding new components, follow
rules/web-interface-guidelines.md
Storybook Stories
- ALWAYS add new stories to
packages/frontend/@n8n/design-system. - Every story must use one of these title categories:
Style Guide: styles, tokens, and utilitiesCore: components used across the appAreas/<Product area>: patterns and components for a specific product area, for exampleAreas/SettingsorAreas/AssistantExperimental: beta components that require caution
- The last
titlesegment is the component name and MUST be PascalCase (Core/EmptyState, notCore/empty-state). Category prefixes are unrestricted.
