TypeScript

function initMap(): void {
  new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    {
      mapId: "8e0a97af9386fef",
      center: { lat: 48.85, lng: 2.35 },
      zoom: 12,
    } as google.maps.MapOptions
  );
}

declare global {
  interface Window {
    initMap: () => void;
  }
}
window.initMap = initMap;
index.ts

JavaScript

function initMap() {
  new google.maps.Map(document.getElementById("map"), {
    mapId: "8e0a97af9386fef",
    center: { lat: 48.85, lng: 2.35 },
    zoom: 12,
  });
}

window.initMap = initMap;
index.js

CSS

/* 
 * 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. 
 */
html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
}
