JavaScript API

Description​

Load the Google Maps JavaScript API script dynamically. This takes inspiration from the google-maps npm package but updates it with ES6, Promises, and TypeScript.

Install​

Available via npm as the package @googlemaps/js-api-loader.

npm i @googlemaps/js-api-loader

Alternatively you may add the umd package directly to the html document using the unpkg link.

<script src="https://unpkg.com/@googlemaps/[email protected]/dist/index.min.js"></script>

When adding via unpkg, the loader can be accessed at google.maps.plugins.loader.Loader.

TypeScript​

TypeScript users need to install the following types package.

npm i -D @types/google.maps

Documentation​

The reference documentation can be found at this link. The Google Maps JavaScript API documentation is the authoritative source for the loader options.

Example​

import { Loader } from '@googlemaps/js-api-loader';

const loader = new Loader({
  apiKey: "",
  version: "weekly",
  libraries: ["places"]
});

const mapOptions = {
  center: {
    lat: 0,
    lng: 0
  },
  zoom: 4
};

Using a promise for a specific library.

// Promise for a specific library
loader
  .importLibrary('maps')
  .then(({Map}) => {
    new Map(document.getElementById("map"), mapOptions);
  })
  .catch((e) => {
    // do something
  });

Using a promise for when the script has loaded.

// Promise
loader
  .load()
  .then((google) => {
    new google.maps.Map(document.getElementById("map"), mapOptions);
  })
  .catch(e => {
    // do something
  });

Alternatively, if you want to use a callback.

// Callback
loader.loadCallback(e => {
  if (e) {
    console.log(e);
  } else {
    new google.maps.Map(document.getElementById("map"), mapOptions);
  }
});
