How to add Bing Maps v8 to Angular 2.0?

Question

I want to add Bing Map V8 control to my Anguar 2.0 project. I want to know what I need to do to add Bing Map V8 into Angular 2.0 project. I have attached my implementation.

Answer 1

I initially tried the accepted answer and ran into the issue some people had in the comments where upon load 'prototype' was null.

I initially solved this by using a try/catch with a setTimeout in the catch that would attempt to load bing after a second. This worked but was a very sloppy solution.

Eventually I looked for how people loaded Google Maps in angular to see if there was a better solution. Thankfully there is and it uses promises.

The solution that worked for me was found here in this answer. Full credit for this goes to them.

First create a service to load your map...

map-loader-service.service

import { Injectable } from '@angular/core';

const url = 'http://www.bing.com/api/maps/mapcontrol?callback=__onBingLoaded&branch=release';

@Injectable()
export class BingMapsLoader {
    private static promise;

    public static load() {
        // First time 'load' is called?
        if (!BingMapsLoader.promise) {

            // Make promise to load
            BingMapsLoader.promise = new Promise( resolve => {

                // Set callback for when bing maps is loaded.
                window['__onBingLoaded'] = (ev) => {
                    resolve('Bing Maps API loaded');
                };

                const node = document.createElement('script');
                node.src = url;
                node.type = 'text/javascript';
                node.async = true;
                node.defer = true;
                document.getElementsByTagName('head')[0].appendChild(node);
            });
        }

        // Always return promise. When 'load' is called many times, the promise is already resolved.
        return BingMapsLoader.promise;
    }
}

In the parent component to the component that contains the bing map element have this code...

import { BingMapsLoader } from './services/map-loader-service/map-loader-service.service';


export class BingMapParentComponent {
    mapReady = false;

    constructor() {
        BingMapsLoader.load()
            .then(res => {
                console.log('BingMapsLoader.load.then', res);
                this.mapReady = true;
        });
    }
}

Additionally, in the template of parent component have this code which will prevent the bing maps component from being initialized until it is ready.

<app-bing-map *ngIf='mapReady'></app-bing-map>

Now, in the bing-map.component itself we want to wait until the component is in the DOM before loading the map.

ngOnInit() {
    if (typeof Microsoft !== 'undefined') {
        console.log('BingMapComponent.ngOnInit');
        this.loadMap();
    }
}

And finally, you load the bing map in the bing-map.component

loadMap() {
    this.map = new Microsoft.Maps.Map(document.getElementById('mapId'), {
        credentials: 'Your Bing Maps Key Here',
    });
}

There is a community effort to build Angular2 directives for Bing Maps. Still in alpha version, but a basic demo can be found here: http://ng2-bingmaps.azurewebsites.net/

The Github repo is here: https://github.com/youjustgo/ng2-bingmaps

Your code is almost ok, you just need few modifications

1- in index.html remove the callback function and the div

<div id='myMap' style='width: 100vw; height: 100vh;'></div>
<script type='text/javascript'>
    function loadMapScenario() {
        var map = new Microsoft.Maps.Map(document.getElementById('myMap'), {
                credentials: 'My Bing Map Key - I removed here'
        });
        var pushpin = new Microsoft.Maps.Pushpin(map.getCenter(), null);
        var layer = new Microsoft.Maps.Layer();
        layer.add(pushpin);
        map.layers.insert(layer);
    }
</script>

Also, in index.html, remove the callback parameter from the script import.

<script type='text/javascript' src='http://www.bing.com/api/maps/mapcontrol?branch=experimental&callback=loadMapScenario' async defer></script>

To be:

<script type='text/javascript' src='http://www.bing.com/api/maps/mapcontrol?branch=experimental' async defer></script>

Now, you have the script loaded, all you need to do is create the map in your component

@Component({
    selector: 'pm-map',
    template: `
    <div class='panel panel-primary'>
      <div class='panel-heading'>
          {{pageTitle}}
      </div>
      <div #myMap style='width: 100%; height: 500px;'></div> 
    </div>`
})
export class MapComponent implements OnInit {
  @ViewChild('myMap') myMap; // using ViewChild to reference the div instead of setting an id
  public pageTitle: string = "Map";

  ngAfterViewInit(){  // after the view completes initializaion, create the map
    var map = new Microsoft.Maps.Map(this.myMap.nativeElement, {
        credentials: 'Bing Map Key - I removed it here'
    });
    var pushpin = new Microsoft.Maps.Pushpin(map.getCenter(), null);
    var layer = new Microsoft.Maps.Layer();
    layer.add(pushpin);
    map.layers.insert(layer);
  }
}
