Add google MAP in javascript application

Create an angular2+ app:

First we need to create an app using "ng new" command, let's create an app using below command:

ng new drag-and-drop

cd drag-and-drop

npm install

After successful "npm install" your angular demo app is created, Now open your terminam/CMD and locate your project root and follow the below steps:

Install googlemaps:

To use google APIs in our component, we need to install a npm modeule "@types/googlemaps". So install this module using below command:

npm install @types/googlemaps — save

The bove command will install the "googlemaps" in your app and make an entry in your package.json file.

Add CDN into your index.html with correct google API key ( Don’t forget it ):

Now we need to add the CDN link in your app's index.html file which is in the root location. Now add below CDN in your insex.html and don't forget to replace your "YOUR_GOOGLE_API_KEY" with keys.

<script src=”https://maps.googleapis.com/maps/api/js?key=YOUR_GOOGLE_API_KEY&callback=initMap"
                          async defer></script>

Add below line to your html where you want to add google map:

This time we need to add the "#googleMap" in your "map.component.html" file

<div #googleMap style="width:300%;height:300px"></div>

Now create the map.component.ts and follow the steps

Now you add below code into your angular component (map.component.ts):

                    import { Component, ViewChild } from ‘@angular/core’;
                    import { } from ‘@types/googlemaps’;
                    
                    @Component({
                      selector: ‘map- component’,
                      templateUrl: ‘./map.component.html’,
                     styleUrls: [‘./ map.component.css’]
                     }) 
                    
                     export class MapComponent {
                    
                      @ViewChild(‘googleMap’) gmapElement: any;
                    
                      map: google.maps.Map; ngOnInit() {
                    
                        var mapProp = {
                          center: new google.maps.LatLng(28.4595, 77.0266),
                          zoom: 14,
                          // mapTypeId: google.maps.MapTypeId.ROADMAP
                          mapTypeId: google.maps.MapTypeId.HYBRID
                          // mapTypeId: google.maps.MapTypeId.SATELLITE
                          // mapTypeId: google.maps.MapTypeId.TERRAIN
                        };
                    
                        this.map = new google.maps.Map(this.gmapElement.nativeElement, mapProp);
                        var marker = new google.maps.Marker({ position: mapProp.center });
                        marker.setMap(this.map);
                    
                        var infowindow = new google.maps.InfoWindow({
                          content: “Hey, We are here”
                        }); infowindow.open(this.map, marker);
                      }
                    }
