Usage

Basic Usage with NGW Provider

import { Geocoder, NgwProvider } from '@nextgis/geocoder';

// Initialize the NGW Provider
const ngwProvider = new NgwProvider({
    connectorOptions: {
        baseUrl: 'https://demo.nextgis.com',
    },
    searchResources: [
        {
            resourceId: 4224,
            limit: 3,
        },
        // ... other resources
    ],
});

// Initialize the geocoder
const geocoder = new Geocoder({ providers: [ngwProvider] });

// Use geocoder.search() for geocoding queries
const searchQuery = "example_search_query"; // Replace with your search term
const geocoderGenerator = geocoder.search(searchQuery);

// Iterate over the geocoder generator to get the search results
for await (const item of geocoderGenerator) {
    console.log(item.text); // Log the item name or description
    item.result().then(({ extent }) => {
        // Use the result's extent or other properties as needed
        console.log(extent);
    });
    break;
}
