Adding the map component using the AWS services to an Angular application


In this article, an application will be created using the latest version of Angular and added to the MapLibre map library with Amazon Amplify Geo APIs and components using the Amazon Location Service location service.


Before you start, you need to install and configure the tools below to create the Angular application.

  • git: Git is a distributed version control system and it will be used to sync the repository.
  • Node.js and npm: Node.js is a JavaScript code runtime software based on Google's V8 engine. npm is a package manager for Node.js (Node.js Package Manager). They will be used to build and run the Angular application and install the libraries.
  • Angular CLI: Angular CLI is a command line utility tool for Angular and it will be used to create the base structure of the Angular application.
  • IDE (e.g. Visual Studio Code or WebStorm): IDE (Integrated Development Environment) is a tool with a graphical interface to help in the development of applications and it will be used to develop the Angular application.

Getting started

Create and configure the account on the Amazon Location Service

Amazon Location Service provides location functionality to applications without compromising data security and user privacy.

1. Let's create and configure the account. Access the site and click on the button Get Started with Amazon Location Service.

Amazon Location Service - Home page

2. Click on the option Root user, fill in the field Root user email address and click on the button Next.

Amazon Location Service - Sign in


3. Fill in the field Security check and click on the button Submit.

Amazon Location Service - Security check

4. Fill in the field Password and click on the button Sign in.

Amazon Location Service - Root user sign in

5. Click on the menu Services.

Amazon Location Service - Add location data

6. Click on the menu Maps.

Amazon Location Service - Menu Services

7. Click on the link Create map.

Amazon Location Service - Maps

8. Fill in the field Name, click on the options Esri Light and To use Amazon Location Maps... and click on the button Create map.

Amazon Location Service - Create map

9. Click on the tab Embed map.

Amazon Location Service - Map information

10. Click on the link Set up authentication, click on the option Create a new Amazon Cognito unauthenticated Identity pool and click on the link Create new Amazon Cognito Identity pool.

Amazon Location Service - Embed map

11. Fill in the field Identity pool name, click on the option Enable access to unauthenticated identities and click on the button Create Pool.

Amazon Location Service - New identity pool

12. Click on the link Edit, fill in the field with the JSON below and click on the link Allow.

  "Version": "2012-10-17",
  "Statement": [
      "Effect": "Allow",
      "Action": [
      "Resource": [
      "Condition": {
        "StringLike": {
          "aws:referer": [

Amazon Location Service - Identity the IAM roles

13. Copy the authentication pool ID displayed and, in my case, the value us-east-1:57a33aaf-0026-44e3-908c-7fb9d5730b9f was displayed because this value will be configured in the Angular application.

14. Ready! Map and authentication pool created.

Create the Angular application

Angular is a development platform for building WEB, mobile and desktop applications using HTML, CSS and TypeScript (JavaScript). Currently, Angular is at version 13 and Google is the main maintainer of the project.

Amazon Amplify Geo provides APIs and components for maps using MapLibre and location using Amazon Location Service for JavaScript-based applications.

MapLibre is an open source map library for developers of WEB and mobile applications.

1. Let's create the application with the Angular base structure using the @angular/cli with the route file and the SCSS style format.

2. Install and configure the Bootstrap CSS framework. Do steps 2 and 3 of the post Adding the Bootstrap CSS framework to an Angular application.

3. Configure the variable amplify.Auth.identityPoolId with the authentication pool ID, the variables amplify.Auth.region and amplify.geo.AmazonLocationService.region with the region and the variables amplify.geo.AmazonLocationService.maps.items[MAP_NAME] and amplify.geo.AmazonLocationService.maps.default wit the map name created in the Amazon Location Service in the src/environments/environment.ts and src/environments/ files as below.

amplify: {
  Auth: {
    identityPoolId: 'us-east-1:57a33aaf-0026-44e3-908c-7fb9d5730b9f',
    region: 'us-east-1',
  geo: {
    AmazonLocationService: {
      maps: {
        items: {
          AmazonMap: {
            style: 'Default style',
        default: 'AmazonMap',
      region: 'us-east-1',

4. Install the aws-amplify, maplibre-gl@1, maplibre-gl-js-amplify and @types/mapbox__mapbox-gl-draw libraries.

npm install aws-amplify maplibre-gl@1 maplibre-gl-js-amplify
npm install @types/mapbox__mapbox-gl-draw --save-dev

7. Remove the content of the AppComponent class from the src/app/app.component.ts file. Import the maplibre-gl-js-amplify service and create the getCurrentPosition and loadMap methods as below.

import { AfterViewInit, Component } from '@angular/core';
import { Observable, Subscriber } from 'rxjs';
import { Amplify } from 'aws-amplify';
import { createMap } from 'maplibre-gl-js-amplify';
import * as maplibregl from 'maplibre-gl';

import { environment } from '../environments/environment';

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
export class AppComponent implements AfterViewInit {

  map: any;

  constructor() {

  public ngAfterViewInit(): void {

  private getCurrentPosition(): any {
    return new Observable((observer: Subscriber<any>) => {
      if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition((position: any) => {
            latitude: position.coords.latitude,
            longitude: position.coords.longitude,
      } else {

  private loadMap(): void {
      container: 'map',
      center: [0, 0],
      zoom: 0,
    .then((map: any) => { = map; maplibregl.NavigationControl()); maplibregl.GeolocateControl());

      .subscribe((position: any) => {{ center: [position.longitude, position.latitude], zoom: 13 });

        const marker = new maplibregl.Marker();
        marker.setLngLat([position.longitude, position.latitude]);
        marker.setPopup(new maplibregl.Popup().setHTML('Angular AWS Map'));

8. Remove the contents of the src/app/app.component.html file. Add the map div tag as below.

<div class="container-fluid py-3">
  <h1>Angular AWS Map</h1>

  <div id="map"></div>

9. Add the style in the src/app/app.component.scss file as below.

#map {

  width: 100%;
  max-width: 600px;
Enter fullscreen mode Exit fullscreen mode

10. Run the application with the command below.

Summarizing what was covered in this article:

  • We created an account on Amazon Web Services (AWS).
  • We created and configured a map on Amazon Location Service
  • We create an Angular application.
  • We added the map in the Angular application.

You can use this article to create applications that display interactive maps to users.
