Add google maps with add marker getting current location using @agm/core module in angular framework

Follow this article to install google map and integrate simple google map into your angular app.

In Previous tutorial we seen google map template using getting current location into angular app like this

HTML Code

// src > app > app.component.html

<div class="googlemap"><!-- app.component.html --><agm-map [latitude]="latitude" [longitude]="longitude" [zoom]="zoom"><agm-marker [latitude]="latitude" [longitude]="longitude"></agm-marker></agm-map>
</div>

CSS Code

// src > app > app.component.css

agm-map {
    height: 500px;
}
 
.googlemap{
    margin-top: 5%;
}

TS Code

import { Component, OnInit } from "@angular/core";
@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"]
})
export class AppComponent implements OnInit {

  title: string = 'Google Map Project';
  latitude: number;
  longitude: number;
  zoom:number;
 
  ngOnInit() {
    this.setCurrentLocation();
  }
    // Get Current Location Coordinates
    private setCurrentLocation() {
      if ('geolocation' in navigator) {
        navigator.geolocation.getCurrentPosition((position) => {
          this.latitude = position.coords.latitude;
          this.longitude = position.coords.longitude;
          this.zoom = 15;
        });
      }
    }
}

This will helps you to set marker into google map to your current location.

Now we see how wee can add multiple markers to adding the multiple restaurant location into the google map.

Just change the HTML code and TS code

// src > app > app.component.html

<div class="googlemap">
 <!-- app.component.html -->
 <agm-map [latitude]="latitude" [longitude]="longitude" [zoom]="zoom">
  <agm-marker *ngFor="let marker of restaurant_list; let i = index" [latitude]="marker.latitude"
   [longitude]="marker.longitude" [label]="marker.name">
  </agm-marker>
 </agm-map>
</div>

In the above code we use for loop to add multiple markers into google map

// src > app > app.component.ts

import { Component, OnInit } from "@angular/core";
@Component({
 selector: "app-root",
 templateUrl: "./app.component.html",
 styleUrls: ["./app.component.css"]
})
export class AppComponent implements OnInit {

 title: string = 'Google Map Project';
 latitude: number;
 longitude: number;
 zoom:number;

 restaurant_list = [
  {
   id : 1,
   name : 'Maharaja Hotel',
   latitude : 20.016112, 
   longitude :73.737208
  },
  {
   id : 2,
   name : 'Peshwa Hotel',
   latitude : 20.013092, 
   longitude :73.748969
  },
  {
   id : 3,
   name : 'Aroma Hotel',
   latitude : 20.014112,
   longitude : 73.713951
  },
 ]
 
 ngOnInit() {
  this.setCurrentLocation();
 }
  // Get Current Location Coordinates
  private setCurrentLocation() {
   if ('geolocation' in navigator) {
    navigator.geolocation.getCurrentPosition((position) => {
     this.latitude = position.coords.latitude;
     this.longitude = position.coords.longitude;
     this.zoom = 15;
    });
   }
  }
}

Here we only added collection of hotel list objects into the array.
