Adding the map TomTom component to an 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 14 and Google is the main maintainer of the project.

@tomtom-international/web-sdk-maps is a library that hides the complexity of integration with TomTom services, boosting the productivity with fully styleable and easily customized components.


Before you start, you need to install and configure the tools:

Getting started

Create and configure the account on the TomTom

1. Let's create the account. Access the site, click on the menu Developers and click on the submenu Developer portal.

TomTom - Home page

2. Click on the button REGISTER.

TomTom - Developer portal

3. Fill in the fields Full name, Username, Email, Password, click on the checkbox I have read and agreed with the terms and conditions for using Maps APIs. and click on the button REGISTER.

TomTom - Register

4. Check the registered email.

TomTom - Check email

5. Click on the button ACTIVATE ACCOUNT in the email sent.

TomTom - Activate account

6. Click on the link MY DASHBOARD.

TomTom - Let's start building

7. Copy the key displayed in the Keys menu and, in my case, the key POQwSkANG2wVgN1qMbook38s5EMkN7pG was displayed because this key will be configured in the Angular application.

TomTom - Keys

8. Ready! Account created and key generated.

Create the Angular application

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 TomTom key in the src/environments/environment.ts and src/environments/ files as below.

4. Install the @tomtom-international/web-sdk-maps library.

"styles": [
Enter fullscreen mode Exit fullscreen mode

6. Remove the contents of the AppComponent class from the src/app/app.component.ts file. Create the getCurrentPosition and loadMap methods as below.

import { AfterViewInit, Component } from '@angular/core';
import { Observable, Subscriber } from 'rxjs';
import * as tt from '@tomtom-international/web-sdk-maps';

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 { ={
      key: environment.tomtom.key,
      container: 'map',
    }); tt.FullscreenControl()); tt.NavigationControl());

    .subscribe((position: any) => {{
        center: {
          lat: position.latitude,
          lng: position.longitude,
        zoom: 13,

      const popup = new tt.Popup({ anchor: 'bottom', offset: { bottom: [0, -40] } }).setHTML('Angular TomTom');

      var marker = new tt.Marker().setLngLat({
        lat: 37.7749,
        lng: -122.4194,

Enter fullscreen mode Exit fullscreen mode

7. 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 TomTom</h1>

  <div id="map" class="map"></div>
Enter fullscreen mode Exit fullscreen mode

8. 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

9. Run the application with the command below.

npm start

> angular-tomtom@1.0.0 start
> ng serve

  • If the error Module '"/node_modules/@types/geojson/index"' has no default export. Did you mean to use 'import { GeoJSON } from "/node_modules/@types/geojson/index"' instead? occurs, add the setting allowSyntheticDefaultImports in the tsconfig.json file as below.
