Common Use Cases

Implement type-ahead city search for a specific country.
class CountryCityAutocomplete {
  constructor(countryCode) {
    this.countryCode = countryCode;
    this.cities = [];
    this.loadCities();
  }
  
  async loadCities() {
    this.cities = await getCitiesByCountry(this.countryCode);
  }
  
  search(query) {
    const lowerQuery = query.toLowerCase();
    return this.cities.filter(city => 
      city.name.toLowerCase().includes(lowerQuery)
    ).slice(0, 10);
  }
  
  setupAutocomplete(inputElement) {
    inputElement.addEventListener('input', (e) => {
      const results = this.search(e.target.value);
      // Display results in dropdown
      this.displaySuggestions(results);
    });
  }
}
Group cities for shipping or service area calculations.
const setupDeliveryZones = async (countryCode) => {
  const cities = await getCitiesByCountry(countryCode);
  
  // Group cities alphabetically for easier management
  const zones = cities.reduce((acc, city) => {
    const firstLetter = city.name.charAt(0).toUpperCase();
    acc[firstLetter] = acc[firstLetter] || [];
    acc[firstLetter].push(city);
    return acc;
  }, {});
  
  return zones;
};
Large Datasets: Countries like the United States, India, and China have thousands of cities. Consider implementing pagination or using the state-filtered endpoint for better performance.
For better user experience, consider loading cities by state instead of by country for countries with many administrative divisions.
