Map Loader for Google Maps Platform JavaScript API v3

Description

Automatically loads a Google map into your website with a few lines of JavaScript or TypeScript. You provide the ID of the div where you want the map initialized or appended to, your settings for what the map looks like, and optionally your settings for loading the Maps JS API, and this module handles the rest.

Loading of the Google Maps Platform JavaScript API is taken care of for you asynchronously courteousy of @googlemaps/js-api-loader.

NPM

Available via NPM as the package @googlemaps/map-loader

Example

Set map loader options

import { GoogleMap } from 'map-loader';

const googleMapsAPIKey = "YOUR API KEY";

/* Options for how the map should initially render. */
const mapOptions = {
  center: {
    lat: 47.649196,
    lng: -122.350384
  },
  zoom: 12
}

/* Options for loading the Maps JS API. */
const apiOptions = {
  version: 'weekly',
  libraries: ['places']
}

/*
 * Set ID of the div where the map will be loaded,
 * and whether to append to that div.
 */
const mapLoaderOptions = {
  apiKey: googleMapsAPIKey,
  divId: 'google_map',
  append: true, // Appends to divId. Set to false to init in divId.
  mapOptions: mapOptions,
  apiOptions: apiOptions
};

Load the map:

// Instantiate map loader
const mapLoader = new GoogleMap();

// Load the map
mapLoader
  .initMap(mapLoaderOptions)
  .then(googleMap => {
    // returns instance of google.maps.Map
  });

Or if you like, with async/await

// Instantiate map loader
const mapLoader = new GoogleMap();

// Load the map
const await googleMap = mapLoader.initMap(mapLoaderOptions);
