tsconfig.app.json

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "outDir": "./out-tsc/app",
    "types": [
      "googlemaps"
    ]
  },
  "files": [
    "src/main.ts",
    "src/polyfills.ts"
  ],
  "include": [
    "src/**/*.d.ts"
  ]
}

Step 3: Import Material AgmCoreModule

Now, here we will import AgmCoreModule from @agm/core and then we add on declarations part. in this file we also need to add Google API Key need to add. you can generate google api key from here: Google Console. so let's update app.module.ts file as like bellow:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
  
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { FormsModule } from '@angular/forms';
import { AgmCoreModule } from '@agm/core';
  
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    FormsModule,
    AgmCoreModule.forRoot({
      apiKey: 'GOOGLE API KEY',
      libraries: ['places']
    })
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 4: Update Ts File

here, we need to update ts file as like bellow with lat and long variable:

src/app/app.component.ts

import { Component } from '@angular/core';
  
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'firstApp';
    
  lat = 22.4064172;
  long = 69.0750171;
  zoom=7;
  
  markers = [
        {
            lat: 21.1594627,
            lng: 72.6822083,
            label: 'Surat'
        },
        {
            lat: 23.0204978,
            lng: 72.4396548,
            label: 'Ahmedabad'
        },
        {
            lat: 22.2736308,
            lng: 70.7512555,
            label: 'Rajkot'
        }
    ];
}

Step 5: Update HTML File

here, we need to update html file as like bellow code:

src/app/app.component.html

<div class="container">
  
  <h1>Angular Google Map Multiple Markers Example - HDTuto.com</h1>
  
    <agm-map 
       [latitude]='lat' 
       [longitude]='long'
       [zoom]='zoom'
       >
        
        <agm-marker 
            *ngFor="let marker of markers" 
            [latitude]="marker.lat" 
              [longitude]="marker.lng">    
                  <agm-info-window #infoWindow>
                      {{ marker.label }}
                </agm-info-window>
        </agm-marker>
        
    </agm-map>
  
</div>

Now you can run by bellow command:

ng serve
