Read the documentation.


// This example adds a map using web components.
async function initMap(): Promise<void> {

// This example adds a map using web components.
async function initMap() {
  const { Map } = await google.maps.importLibrary("maps");

 * Always set the map height explicitly to define the size of the div element
 * that contains the map. 
#map {
  height: 100%;

 * Optional: Makes the sample page fill the window.

  height: 100%;
  margin: 0;
  padding: 0;

gmp-map {
  height: 400px;
