How can I integrate Google Maps APIs inside an Angular 2 component

Question

I have an Angular 2 component that is defined in the file comp.ts in this way like this:

import {Component} from \'angular2/core\';

@component({
    selecto         


        

Answer 1

I have found a solution. First of all, the following line:

must be inserted in the index.html file. The code which creates the map must be inserted in the comp.ts file. In particular, it must be inserted in a special method, namely "ngOnInit", which can be positioned after the constructor of the class. This is comp.ts:

import { Component } from 'angular2/core';

declare const google: any;

@Component({
    selector: 'my-app',
    templateUrl:'appHtml/app.html',
    styleUrls: ['css/app.css']
})

export class AppMainComponent {
    constructor() {}
    ngOnInit() {
        let mapProp = {
            center: new google.maps.LatLng(51.508742, -0.120850),
            zoom: 5,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        let map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
    }
}

Finally, the div with id "googleMap", which is going to contain the google map, must be inserted in the comp.html file, which will look like this:
