### Load Google Maps JavaScript API with Libraries

Source: https://github.com/googlemaps/js-samples/blob/main/dist/samples/event-arguments/app/index.html

This JavaScript code snippet dynamically loads the Google Maps JavaScript API. It allows specifying libraries and API keys, and handles the asynchronous loading process. It's designed to be a one-time setup for the API.

```javascript
var google = window.google || (window.google = {});
var maps = google.maps || (google.maps = {});

const loadGoogleMaps = (async ({ key, v, libraries = [] }) => {
  let script = document.createElement('script');
  const params = new URLSearchParams();
  params.set('libraries', libraries.join(','));
  params.set('key', key);
  params.set('v', v);
  params.set('callback', 'google.maps.__ib__');

  script.src = `https://maps.googleapis.com/maps/api/js?${params.toString()}`;
  script.nonce = document.querySelector('script[nonce]')?.nonce || '';

  return new Promise((resolve, reject) => {
    maps.__ib__ = resolve;
    script.onerror = () => reject(Error('The Google Maps JavaScript API could not load.'));
    document.head.append(script);
  });
});

maps.importLibrary = (libraryName) => {
  if (maps.importLibrary.loaded) {
    console.warn('The Google Maps JavaScript API only loads once. Ignoring:', { libraryName });

### Calculate and Display Routes with Directions Service in TypeScript

Source: https://context7.com/googlemaps/js-samples/llms.txt

Calculates and displays driving routes between two locations using the Google Maps Directions Service. It takes origin and destination inputs from HTML elements and renders the route on the map. Requires HTML elements with IDs 'start', 'end', and 'map'.

```typescript
function initMap(): void {
  const directionsService = new google.maps.DirectionsService();
  const directionsRenderer = new google.maps.DirectionsRenderer();
  const map = new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    {
      zoom: 7,
      center: { lat: 41.85, lng: -87.65 },
    }
  );

  directionsRenderer.setMap(map);

  const onChangeHandler = function () {
    calculateAndDisplayRoute(directionsService, directionsRenderer);
  };

  document.getElementById("start").addEventListener("change", onChangeHandler);
  document.getElementById("end").addEventListener("change", onChangeHandler);
}

function calculateAndDisplayRoute(
  directionsService: google.maps.DirectionsService,
  directionsRenderer: google.maps.DirectionsRenderer
) {
  directionsService
    .route({
      origin: {
        query: (document.getElementById("start") as HTMLInputElement).value,
      },
      destination: {
        query: (document.getElementById("end") as HTMLInputElement).value,
      },
      travelMode: google.maps.TravelMode.DRIVING,
    })
    .then((response) => {
      directionsRenderer.setDirections(response);
    })
    .catch((e) => window.alert("Directions request failed due to " + e));
}

window.initMap = initMap;

### Create and Style Polygon Overlays

Source: https://context7.com/googlemaps/js-samples/llms.txt

This TypeScript example demonstrates how to create and style a polygon shape on a Google Map. It defines the coordinates for the polygon's path, creates a new google.maps.Polygon object with specified stroke and fill properties, and adds it to the map. An event listener is included to log information when the polygon is clicked.

```typescript
function initMap(): void {
  const map = new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    {
      zoom: 5,
      center: { lat: 24.886, lng: -70.268 },
      mapTypeId: "terrain",
    }
  );

  // Define the polygon path
  const triangleCoords = [
    { lat: 25.774, lng: -80.19 },
    { lat: 18.466, lng: -66.118 },
    { lat: 32.321, lng: -64.757 },
    { lat: 25.774, lng: -80.19 },
  ];

  // Create the polygon
  const bermudaTriangle = new google.maps.Polygon({
    paths: triangleCoords,
    strokeColor: "#FF0000",
    strokeOpacity: 0.8,
    strokeWeight: 2,
    fillColor: "#FF0000",
    fillOpacity: 0.35,
  });

  bermudaTriangle.setMap(map);

  // Add click listener
  bermudaTriangle.addListener('click', (event) => {
    console.log('Polygon clicked at:', event.latLng.toString());
  });
}

window.initMap = initMap;
