# Google Maps JavaScript API Loader
## Description
Load the Google Maps JavaScript API script dynamically. This takes inspiration from the [google-maps](https://www.npmjs.com/package/google-maps) npm package but updates it with ES6, Promises, and TypeScript.
## Requirements
* [Sign up with Google Maps Platform]
* A Google Maps Platform [project] with the [**Maps Javascript API**][maps-sdk] enabled
* An [API key] associated with the project above
* [@googlemaps/js-api-loader NPM package][npm-pkg]
## Installation
Install the [@googlemaps/js-api-loader NPM package][npm-pkg] with:
```sh
npm i @googlemaps/js-api-loader
```
Alternatively you may add the umd package directly to the html document using the unpkg link.
```html
```
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.
```sh
npm i -D @types/google.maps
```
## Documentation
The reference documentation can be found at this [link](https://googlemaps.github.io/js-api-loader/index.html). The Google Maps JavaScript API [documentation](https://developers.google.com/maps/documentation/javascript/tutorial) is the authoritative source for the loader options.
## Usage
```javascript
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.
```javascript
// 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.
```javascript
// 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.
```javascript
// Callback
loader.loadCallback(e => {
if (e) {
console.log(e);
} else {
new google.maps.Map(document.getElementById("map"), mapOptions);
}
});
```
