Installation

tns plugin add nativescript-plugin-google-places

Usage

To import:

import * as GooglePlaces from 'nativescript-plugin-google-places';

Run the init function in the App.Module constructor if you're using angular or the app.ts file otherwise

GooglePlaces.init();

To have the user pick a place:

GooglePlaces.pickPlace()
    .then(place => console.log(JSON.stringify(place)))
    .catch(error => console.log(error));

To set a default location for the map to start on:

let center: Location = {
    latitude: -33.865143,
    longitude: 151.2099
}

let viewport = {
    northEast: {
        latitude: center.latitude + 0.001,
        longitude: center.longitude + 0.001
    },
    southWest: {
        latitude: center.latitude - 0.001,
        longitude: center.longitude - 0.001
    }
}

GooglePlaces.pickPlace(viewport)
    .then(place => console.log(JSON.stringify(place)))
    .catch(error => console.log(error));

To get places using ids:

GooglePlaces.getPlacesById([
    "ChIJ4zPXqIiAhYAR31X3S64T6Uw",
    "ChIJ6zMe3oWAhYARaZ33Z1BAMRo",
    "ChIJAUWoGIaAhYARQ6zvky_f10Q"
])
    .then((places: GooglePlaces.Place[]) => {
        places.forEach(place => console.log(place.name));
    })
    .catch(error => console.log(error));

To get a static map:

this.staticMapUrl = GooglePlaces.getStaticMapUrl(
    place, 
    { 
        width: 250,
        height: 250
    }
);

Or by address:

this.staticMapUrl = GooglePlaces.getStaticMapUrlByAddress(
    place.address,
    {
        width: 250,
        height: 250
    }
);

<Image *ngIf="staticMapUrl" [src]="staticMapUrl" width="250" height="250"></Image>

Best Practices

• Google recommends always displaying the attributions string, when available, when using the Place data.
• Google requires the "Powered by Google" picture next to Place data whenever the data is used outside of the map. The picture is installed by the plugin if you allow it to during the setup script.

You can use the light version:

<Image res="res://powered_by_google_light" stretch="none"></Image>

or the dark version:

<Image res="res://powered_by_google_dark" stretch="none"></Image>

Updates

v1.1.2

• Fixed iOS bug where panning the map would destroy the link to resolve the promise, leaving the user stuck in the map view.
• Installer script now adds iOS images manually since the cocoapods version was inaccessible. If updating rather than installing for the first time, run:

cd node_modules/nativescript-plugin-google-places && npm run configure

v1.2.0

• Added getPlacesById(id: string[]): Place[]
• Fixed Android error where place returned by placepicker would not have all of the info

v1.2.1

• Fixed setup error where ios keys were not being replaced after reconfiguring
• Fixed getPlacesById error where ios results were being returned in reverse order
• Added error handling to Android for getPlacesById if not all places can be found

Now you can be sure the places array you get from getPlacesById has the same number of elements and is in the same order as the ids you send it.

v1.3.0

• Added getStaticMapUrl(place: Place, options: { width: number, height: number }): string
• Updated installer to request browser key for the static maps. Run npm run configure to update

v1.3.1

• Added "types" to Place definition.

v1.4.1

• Added getStaticMapUrlByAddress(address: string, options: { width: number, height: number }): string
