Uso de las herramientas y bibliotecas de MapLibre con Amazon Location

Puede instalar el complemento de geocodificador MapLibre en Amazon Location desde NPM para el uso con módulos mediante este comando:

npm install @aws/amazon-location-for-maplibre-gl-geocoder

Puede importarlo a un archivo HTML para usarlo directamente en el navegador con un script:

<script src="https://www.unpkg.com/@aws/amazon-location-for-maplibre-gl-geocoder@1">/script<

Este código configura un mapa de JavaScript de Maplibre GL con capacidades de geocodificación de Amazon Location. Utiliza la autenticación mediante el grupo de identidades de Amazon Cognito para acceder a los recursos de Amazon Location. El mapa se representa con un estilo y coordenadas centrales específicos, y permite buscar lugares en el mapa.

// Import MapLibre GL JS
import maplibregl from "maplibre-gl";
// Import from the AWS JavaScript SDK V3
import { LocationClient } from "@aws-sdk/client-location";
// Import the utility functions
import { withIdentityPoolId } from "@aws/amazon-location-utilities-auth-helper";
// Import the AmazonLocationWithMaplibreGeocoder
import { buildAmazonLocationMaplibreGeocoder, AmazonLocationMaplibreGeocoder } from "@aws/amazon-location-for-maplibre-gl-geocoder"

const identityPoolId = "Identity Pool ID";
const mapName = "Map Name";
const region = "Region"; // region containing the Amazon Location resource
const placeIndex = "PlaceIndexName" // Name of your places resource in your AWS Account. 

// Create an authentication helper instance using credentials from Amazon Cognito
const authHelper = await withIdentityPoolId("Identity Pool ID");

const client = new LocationClient({
  region: "Region", // Region containing Amazon Location resources
  ...authHelper.getLocationClientConfig(), // Configures the client to use credentials obtained via Amazon Cognito
});

// Render the map
const map = new maplibregl.Map({
    container: "map",
    center: [-123.115898, 49.295868],
    zoom: 10,
    style: `https://maps.geo.${region}.amazonaws.com/maps/v0/maps/${mapName}/style-descriptor`,
    ...authHelper.getMapAuthenticationOptions(),
});

// Gets an instance of the AmazonLocationMaplibreGeocoder Object. 
const amazonLocationMaplibreGeocoder = buildAmazonLocationMaplibreGeocoder(client, placeIndex, {enableAll: true});
    
// Now we can add the Geocoder to the map.
map.addControl(amazonLocationMaplibreGeocoder.getPlacesGeocoder());

En este ejemplo, se utiliza el cliente de Amazon Location para realizar una solicitud que se autentica mediante Amazon Cognito.
