Gunakan MapLibre alat dan pustaka dengan Lokasi Amazon

Anda dapat menginstal plugin MapLibre geocoder Lokasi Amazon dari NPM untuk penggunaan dengan modul, dengan perintah ini:

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

Anda dapat mengimpor ke HTML file untuk digunakan langsung di browser, dengan skrip:

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

Kode ini menyiapkan JavaScript peta Maplibre GL dengan kemampuan geocoding Lokasi Amazon. Ini menggunakan otentikasi melalui Amazon Cognito Identity Pool untuk mengakses sumber daya Lokasi Amazon. Peta dirender dengan gaya dan koordinat pusat yang ditentukan, dan memungkinkan untuk mencari tempat di peta.

// 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());

Contoh ini menggunakan Klien Lokasi Amazon untuk membuat permintaan yang mengautentikasi menggunakan Amazon Cognito.

// Create an authentication helper instance using credentials from Amazon Cognito
const authHelper = await amazonLocationAuthHelper.withIdentityPoolId(identityPoolId);

// Render the map
const map = new maplibregl.Map({

});

// Initialize the AmazonLocationMaplibreGeocoder object
const amazonLocationMaplibreGeocoderObject = amazonLocationMaplibreGeocoder.buildAmazonLocationMaplibreGeocoder(client, placesName, {enableAll: true});

// Use the AmazonLocationWithMaplibreGeocoder object to add a geocoder to the map. 
map.addControl(amazonLocationMaplibreGeocoderObject.getPlacesGeocoder());
