@turistikrota/location-tr is a TypeScript package designed to provide functionality for location-based operations in Turkey. It now includes an expanded set of features, such as finding the nearest districts, district names, and city names, as well as fetching a sorted list of cities and districts.

Installation

npm install @turistikrota/location-tr

Usage

import {
  Coordinates,
  City,
  District,
  findNearestDistrict,
  findNearestDistrictNames,
  findNearestCityNames,
  getCities,
  getDistricts,
  useCities,
} from '@turistikrota/location-tr';

// Example coordinates
const coordinates: Coordinates = [latitude, longitude];

// Find the nearest district
const nearestDistrict: District | null = findNearestDistrict(coordinates);

// Find the nearest district names
const nearestDistrictNames: string[] = findNearestDistrictNames(coordinates, 5);

// Find the nearest city names
const nearestCityNames: string[] = findNearestCityNames(coordinates, 3);

// Get a sorted list of cities
const sortedCities: City[] = getCities();

// Get a sorted list of districts
const sortedDistricts: District[] = getDistricts();

// Use filtered cities
const filteredCities: City[] = useCities('Istanbul');
