Angular2 Google Map (ng-map version 2)

If you like this, you may also like these;

Design Principle

  1. All google properties must be able to be defined in html without Javascript.

    Thus, basic users don't even have to know what Javascript is.

  2. Expose all original Google Maps V3 api to the user without any exception.

    No hiding or manipulation. By doing so, programmers don't need to learn anything about this convenient module. If you know Google Maps V3 API, there shouldn't be a problem using this module.


  1. Install node_module @ngui/map and typings

     $ npm install @ngui/map @types/googlemaps --save
  2. For SystemJs users only, update system.config.js to recognize @ngui/map.

     map['@ngui/map'] = 'node_modules/@ngui/map/dist/map.umd.js';
  3. import NguiMapModule to your AppModule

     import { NgModule } from '@angular/core';
     import { FormsModule } from "@angular/forms";
     import { BrowserModule  } from '@angular/platform-browser';
     import { AppComponent } from './app.component';
     import { NguiMapModule} from '@ngui/map';
       imports: [
         NguiMapModule.forRoot({apiUrl: ''})
       declarations: [AppComponent],
       bootstrap: [ AppComponent ]
     export class AppModule { }

Use it in your template

<ngui-map center="Brampton, Canada"></ngui-map>


<ngui-map [options]="mapOptions"></ngui-map>

For a full example, please check out the app directory to see the example:

  • main.ts
  • and app/map-components.

How to get a instance(s) of a map or markers

  • Nui2MapComponent fires mapReady$ event with map object
  • Each ngui-map directives fires initialized$ event with its Google map object, e.g. google.maps.Marker
  • Other way is to get a map object is to any event. All event has target value, which is a Google map object.
  center="37.775, -122.434" 
    <marker *ngFor="let pos of positions" 

In your app component:

export class MyAppComponent {
  onMapReady(map) {
    console.log('map', map);
    console.log('markers', map.markers);  // to get all markers as an array 
  onIdle(event) {
  onMarkerInit(marker) {
    console.log('marker', marker);
  onMapClick(event) {
