Render customization

Override any rendering zone while keeping built-in search logic and keyboard navigation:

<AddressAutocomplete
  apiUrl="https://api.addressr.io/"
  onSelect={handleSelect}
  renderLoading={() => <li>Loading addresses...</li>}
  renderNoResults={() => <li>No matches found</li>}
  renderError={(err) => <div role="alert">Error: {err.message}</div>}
  renderItem={(item, highlighted, segments) => (
    <span>{segments.map((s, i) => s.highlighted ? <mark key={i}>{s.text}</mark> : s.text)}</span>
  )}
/>

When you provide a custom renderer, you are responsible for accessibility in that zone -- use appropriate roles and contrast ratios.

Headless hook

Build your own UI while keeping the search logic, debounce, pagination, and abort handling:

import { useAddressSearch } from '@mountainpass/addressr-react';

function MyCustomAutocomplete() {
  const {
    query, setQuery,
    results, isLoading,
    hasMore, loadMore, isLoadingMore,
    selectedAddress, selectAddress,
    error, clear,
  } = useAddressSearch({ apiUrl: 'https://api.addressr.io/' });

  return (
    <div>
      <input value={query} onChange={(e) => setQuery(e.target.value)} />
      <ul>
        {results.map((r) => (
          <li key={r.pid} onClick={() => selectAddress(r.pid)}>{r.sla}</li>
        ))}
        {hasMore && <li onClick={loadMore}>Load more...</li>}
      </ul>
    </div>
  );
}

Return values

Property	Type	Description
query	string	Current input value
setQuery	(q: string) => void	Update query (triggers debounced search)
results	AddressSearchResult[]	Search results (accumulated across pages)
isLoading	boolean	Initial search in progress
isLoadingMore	boolean	Pagination fetch in progress
hasMore	boolean	More pages available
loadMore	() => Promise<void>	Load next page of results
error	Error | null	Latest error
selectedAddress	AddressDetail | null	Selected address detail
selectAddress	(pid: string) => Promise<void>	Fetch full address detail
clear	() => void	Reset all state

Theming

All visual styles use CSS custom properties. Override on any ancestor element:

.my-form {
  --addressr-font-family: 'Inter', sans-serif;
  --addressr-border-color: #ccc;
  --addressr-focus-color: #0066cc;
  --addressr-highlight-bg: #e0f0ff;
  --addressr-error-color: #c62828;
}

Token	Default	Description
--addressr-font-family	system-ui, -apple-system, sans-serif	Font stack
--addressr-padding-x	0.75rem	Horizontal padding
--addressr-padding-y	0.625rem	Vertical padding
--addressr-text-color	inherit	Text color
--addressr-border-color	#767676	Input and dropdown border
--addressr-border-radius	0.25rem	Corner radius
--addressr-focus-color	#005fcc	Focus ring and border
--addressr-z-index	1000	Dropdown stacking order
--addressr-bg	#fff	Dropdown background
--addressr-shadow	0 4px 6px rgba(0,0,0,0.1)	Dropdown shadow
--addressr-highlight-bg	#e8f0fe	Active item background
--addressr-mark-weight	700	Search match font weight
--addressr-mark-color	inherit	Search match text color
--addressr-muted-color	#555	Status and empty text
--addressr-error-color	#d32f2f	Error message text
--addressr-skeleton-from	#e0e0e0	Loading skeleton base
--addressr-skeleton-to	#f0f0f0	Loading skeleton shimmer

The loading state shows animated skeleton lines instead of text. The animation respects prefers-reduced-motion: reduce.

Accessibility

Built with downshift for WAI-ARIA combobox pattern compliance:

• Full keyboard navigation (Arrow keys, Enter, Escape)
• Screen reader announcements for results count and loading state
• Visible focus indicators (3:1 contrast)
• Touch targets >= 44px
• Accessible label always present
• Infinite scroll with loading indicator

Re-exports

This package re-exports everything from @mountainpass/addressr-core for convenience -- createAddressrClient, parseHighlight, and all types.
