Component Library

This document provides documentation for the reusable components in the Kuviq application.

Overview

Components are organized into these categories:

Common - Generic, reusable UI components
Forms - Form controls and layouts
Dashboard - Dashboard widgets
Inspections - Inspection-specific components
Layout - Page layout components

All components are built with Material-UI and follow consistent patterns for:

Accessibility (WCAG AA compliant)
Responsive design
Theme integration
TypeScript types

Best Practices

Accessibility

All components follow WCAG AA guidelines:

Minimum 4.5:1 color contrast
Keyboard navigation support
ARIA attributes where needed
Focus management

Responsive Design

Components use MUI breakpoints:

sx={{
  width: { xs: '100%', sm: '50%', md: '33%' },
  padding: { xs: 2, md: 3 },
}}

Touch Targets

Minimum 44px touch targets on mobile:

sx={{
  minWidth: { '@media (pointer: coarse)': 44 },
  minHeight: { '@media (pointer: coarse)': 44 },
}}

Responsive Button Layout

Button groups must be responsive. Use column layout on mobile with full-width buttons:

import { useTheme, useMediaQuery, Box, Button } from '@mui/material'

function MyComponent() {
  const theme = useTheme()
  const isMobile = useMediaQuery(theme.breakpoints.down('sm'))

  return (
    <Box
      sx={{
        display: 'flex',
        flexDirection: isMobile ? 'column' : 'row',
        gap: 1,
      }}
    >
      <Button variant="outlined" fullWidth={isMobile}>
        Cancel
      </Button>
      <Button variant="contained" fullWidth={isMobile}>
        {isMobile ? 'Save' : 'Save Changes'}
      </Button>
    </Box>
  )
}

Key patterns:

Use fullWidth={isMobile} on all action buttons
Use column layout on mobile, row on desktop: flexDirection: isMobile ? 'column' : 'row'
Shorten button text on mobile when needed (e.g., "Save" vs "Save Changes")
For dialogs, use fullScreen={isMobile} prop on the Dialog component

For DialogActions, apply custom styling to stack buttons:

<DialogActions
  sx={{
    flexDirection: isMobile ? 'column' : 'row',
    gap: isMobile ? 1 : 0,
    p: isMobile ? 2 : undefined,
    '& > :not(:first-of-type)': { ml: isMobile ? 0 : undefined },
  }}
>

Theme Integration

Use theme tokens for consistency:

sx={{
  color: 'primary.main',
  backgroundColor: 'background.paper',
  borderColor: 'divider',
}}

TypeScript

All components are fully typed:

interface MyComponentProps {
  title: string
  onAction?: () => void
  children: React.ReactNode
}

export default function MyComponent({ title, onAction, children }: MyComponentProps) {
  // ...
}
