Components

Buttons

• Use Quasar's q-btn for all buttons
• Never create custom button components unless absolutely necessary
• Preferred icon: mdi-arrow-left for back navigation

Dialogs and Modals

• CRITICAL: Never use browser alert(), confirm(), or prompt()
• Always use Quasar's dialog system
• For notifications, use $q.notify() plugin

Forms

• Use Quasar Form components with validation
• Always show loading states during async submission
• Disable submit button while submitting

Notifications

Never:

alert('Error occurred')  // ❌ FORBIDDEN

Always:

$this.$q.notify({
  type: 'positive',  // or 'negative', 'warning', 'info'
  message: 'Success!',
  position: 'top'
})

Layout

Navigation

• Use q-layout with q-header, q-drawer, q-page-container
• Back button should be top-left in header
• Mobile: drawer for navigation, Desktop: drawer or tabs

Responsive Design

• Mobile-first approach
• Test at 375px, 768px, 1024px breakpoints
• Hide desktop-only elements on mobile with $q.screen.gt.md

Styling

Colors

• Use Quasar's color palette (primary, secondary, accent, etc.)
• Define project colors in quasar.variables.scss
• Never hardcode hex colors in components

Spacing

• Use Quasar's spacing classes (q-pa-md, q-gutter-sm, etc.)
• Consistent padding: q-pa-md for cards, q-pa-sm for form elements

Accessibility

ARIA Labels

• Always add labels to icon-only buttons
• Use descriptive labels for screen readers

<q-btn icon="mdi-close" aria-label="Close dialog" />

Keyboard Navigation

• All interactive elements must be keyboard accessible
• Use tabindex carefully (avoid if possible)
• Test with Tab, Enter, and Escape keys

Performance

Images

• Use q-img for lazy loading
• Optimize images before adding to project
• Use WebP format when browser support allows

Lists

• Use virtual scrolling for lists > 100 items (q-virtual-scroll)
• Avoid rendering all items at once
