Key Components

SearchAutocomplete

Generic, fully-typed search autocomplete component accepting:

• query — Current search input
• onQueryChange — Input change handler
• onFetch — Async fetch function returning SearchResult[]
• onSelect — Selection callback
• isLoading — Loading state
• error — Error message display
• results — Array of search results
• renderItem — Custom result item renderer (optional)

SearchResult Interface

interface SearchResult {
  id: string;
  title: string;
  subtitle?: string;
  metadata?: Record<string, any>;
}

Error Handling

The app includes:

• Runtime Error Capture — Global error listener displays formatted error overlay
• Promise Rejection Handling — Catches unhandled promise rejections
• Network Error Simulation — 10% of mock requests fail to demonstrate error UI
• Timeout Detection — Loading screen times out after 60 seconds with user-friendly message

Accessibility

• ARIA combobox role on input
• aria-expanded reflects dropdown state
• aria-activedescendant points to focused result
• Keyboard-only navigation fully supported
• Semantic HTML structure
• Color contrast compliant
