Angular 17,16 Google Maps Integration Example

Steps to integrate Google Maps in angular 17,16 projects and display multiple markers on Google Maps:

Step 1 – Set up the Angular Project

First of all, open your cmd or command prompt and execute the following command on it to install and create a new angular project:

ng new angular-maps-app --no-standalone
cd angular-maps-app

Step 2 – Install @angular/google-maps npm Module

To install Google Maps modules by using npm install @angular/google-maps; like following:

npm install @angular/google-maps

Step 3 – Set Up Google Maps API Key

To use Google Maps in your application, you’ll need an API key. Follow these steps to get one:

1. Go to the Google Cloud Console: https://console.cloud.google.com/
2. Create a new project (if you don’t have one already).
3. In the dashboard, click on “APIs & Services” > “Credentials”.
4. Click on “Create Credentials” and select “API Key”.
5. Copy the generated API key.

Step 4 – Import Module in TypeScript File

Simply navigate to src/app folder and open app.module.ts, then import google map module like following into it:

  imports: [
    BrowserModule,
    GoogleMapsModule
  ],

Step 5 – Create Google Map in HTML Template

Navigate to your src folder and open index.html file, then add the google map script with api key in it like following:

<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCaKbVhcX_22R_pRKDYuNA7vox-PtGaDkI"></script>

Note:- Please replace ‘key‘ in index.html file with your google api key.

Next navigate to src/app directory and open app.component.html and add the following code to it:

<h1>Integrate Google Maps in Angular - Tutsmake.com</h1>
  
<google-map height="450px"
            width="1000px"
            [center]="center"
            [zoom]="zoom"
            (mapClick)="moveMap($event)"
            (mapMousemove)="move($event)">
</google-map>
  
<div>Latitude: {{display?.lat}}</div>
<div>Longitude: {{display?.lng}}</div>

Step 6 – Implement the Map Component

Navigate to src/app directory and open app.component.ts and then add the following code to component.ts file:

import { Component, OnInit } from '@angular/core';
    
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
    
    constructor() {}
      
    ngOnInit(): void {}
  
    display: any;
    center: google.maps.LatLngLiteral = {
        lat: 22.2736308,
        lng: 70.7512555
    };
    zoom = 6;
  
    /*------------------------------------------
    --------------------------------------------
    moveMap()
    --------------------------------------------
    --------------------------------------------*/
    moveMap(event: google.maps.MapMouseEvent) {
        if (event.latLng != null) this.center = (event.latLng.toJSON());
    }
  
    /*------------------------------------------
    --------------------------------------------
    move()
    --------------------------------------------
    --------------------------------------------*/
    move(event: google.maps.MapMouseEvent) {
        if (event.latLng != null) this.display = event.latLng.toJSON();
    }
}

Step 7 – Start the Angular Google Login App

In this step, execute the following command on terminal to start angular apps:

ng serve

Open your browser and navigate to http://localhost:4200. You should see the map centered on the specified latitude and longitude with a marker.
