Wiring up Google Maps Nativescript plugin with Angular 2

Question

I'm trying to use the Google Maps plugin for Nativescript (https://github.com/dapriett/nativescript-google-maps-sdk) with Angular 2 and the {N}-Angular router. I have it working in just Nativescript but once I add in Angular 2 and the router I'm failing to get the map to show up in the UI.

Since a <Page> tag doesn't go into an Angular2 {N} component template, I can't use the xmlns:maps="nativescript-google-maps-sdk" namespace on the <Page> to instantiate the <maps:mapView>

The {N} component basics page gives some guidance but it doesn't work in the ways I've tried: https://docs.nativescript.org/ui/ui-with-xml#user-interface-components

Any idea on the proper way to do this is?

app.component.ts

import {Component} from "angular2/core";
import {RouteConfig} from "angular2/router";
import {NS_ROUTER_DIRECTIVES, NS_ROUTER_PROVIDERS} from "nativescript-angular/router";
import {HomeComponent} from "./pages/home/home.component";

@Component({
    selector: "app-main",
    directives: [NS_ROUTER_DIRECTIVES],
    providers: [NS_ROUTER_PROVIDERS],
    template: "<page-router-outlet ></page-router-outlet>"
})
@RouteConfig([
    { path: "/home", component: HomeComponent, as: "Home", useAsDefault: true },
])
export class AppComponent {
}

home.html

<stack-layout orientation="vertical">
    <label [text]="message"></label>
    <mapView [latitude]="latitude" [longitude]="longitude"
                  [zoom]="zoom" [bearing]="bearing"
                  [tilt]="tilt" (mapReady)="OnMapReady"
                  (markerSelect)="onMarkerSelect"
                  (cameraChanged)="onCameraChanged">
    </mapView>
</stack-layout>

home.component.ts

import {Component} from "angular2/core";
var geolocation = require("nativescript-geolocation");
var mapsModule = require("nativescript-google-maps-sdk");
exports.mapView = mapsModule.MapView; //Doesn't work
exports.mapView = new mapsModule.MapView(); //Doesn't work
exports.mapView = mapsModule; //Doesn't work

@Component({
    selector: "home",
    templateUrl: "pages/home/home.html",
})
export class HomeComponent {
    public message:string = "Message set.";
    public latitude:number = 30.0;
    public longitude:number = -100.0;
    public zoom:number = 10;
    public bearing:number = 0;
    public tilt:number = 0;

    constructor() {
        this.message = "Home constructed.";
    }
    OnMapReady(args) { }
    onMarkerSelect(args) { }
    onCameraChanged(args) { }
}

Answer 1

You need to register the mapView tag name with the element-registry API e.g.:

https://github.com/NativeScript/nativescript-angular/blob/master/src/nativescript-angular/element-registry.ts#L70-L105

That API isn't documented yet, but we should fix that problem in the coming weeks.

Answer 2

I found that using this plugin with ns angualr 2 I had to manually add the applicationID to the build.gradle file in root/platforms/adnroid under:

android{
    defaultConfig{
        applicationId "org.nativescript.my_app_name"

This was after i used tns plugin add nativescript-google-sdk.

Otherwise the app was building successfully but when deployed would not install on device or emulator and checking the logcat, I find this odd as nativescript would not have you edit the build.gradle file ever. Now it works great using the code from other answer
