Ember-g-map

An ember-cli add-on for easy integration with Google Maps. Each object displayed on map is inserted via child component, so you can easily declare which marker and when to display on map using {{#if}} and {{#each}} on template level.

Installation

• ember install ember-g-map

Configuration

You must define the size of the canvas in which the map is displayed. Simply add something similar to this to your styles:

.g-map-canvas {
  width: 600px;
  height: 400px;
}

In config/environment.js you can specify additional Google Maps libraries to be loaded along with this add-on (check the full list here) and optional API key for your application (additional info could be found here).

ENV['g-map'] = {
  libraries: ['places', 'geometry'],
  key: 'your-unique-google-map-api-key'
}

Usage

Simple map

{{g-map lat=37.7833 lng=-122.4167 zoom=12}}

Map with custom options

Any custom options (except for center and zoom to avoid conflicts) could be set for Google Map object on creation and updated on change.

{{g-map lat=37.7833 lng=-122.4167 zoom=12 options=customOptions}}

Map with Markers

Mandatory context attribute ties child-elements with the main g-map component. You can set simple title appearing on click using title attribute and marker label using label.

{{#g-map lat=37.7833 lng=-122.4167 zoom=12 as |context|}}
  {{g-map-marker context lat=37.7933 lng=-122.4167}}
  {{g-map-marker context lat=37.7833 lng=-122.4267 title=titleForSecondMarker}}
  {{g-map-marker context lat=37.7733 lng=-122.4067 label="3" title="Marker #3"}}
{{/g-map}}

Map with Info Windows

These Info Windows will be open right after component is rendered and will be closed forever after user closes them. You can specify optional onClose action to tear down anything you need when Info Window has been closed by user.

{{#g-map lat=37.7833 lng=-122.4167 zoom=12 as |context|}}
  {{#g-map-infowindow context lat=37.7733 lng=-122.4067}}
    <h1>Info Window with Block</h1>
    <p>Text with {{bound}} variables</p>
    <button {{action "do"}}>Do</button>
  {{/g-map-infowindow}}
  {{g-map-infowindow context lat=37.7733 lng=-122.4067
                     title="Blockless form" message="Plain text."}}
  {{g-map-infowindow context lat=37.7733 lng=-122.4067
                     title="With action set"
                     onClose="myOnCloseAction"}}
  {{g-map-infowindow context lat=37.7733 lng=-122.4067
                     title="With closure action set"
                     onClose=(action "myOnCloseAction")}}
{{/g-map}}

Map fits to show all initial Markers

markersFitMode attribute overrides lat, lng, zoom settings. markersFitMode value can be one of:

• 'init' - which will make the map fit the markers on creation.
• 'live' - which will keep the map keep fitting the markers as they are added, removed or moved.

{{#g-map markersFitMode='live' as |context|}}
  {{g-map-marker context lat=37.7933 lng=-122.4167}}
  {{g-map-marker context lat=37.7833 lng=-122.4267}}
  {{g-map-marker context lat=37.7733 lng=-122.4067}}
{{/g-map}}

Map with Markers and bound Info Windows

Markers can have bound Info Windows activated on click. To properly bind Info Window with Marker you should call g-map-marker in block form and set context of Info Window to the one provided by Marker.

{{#g-map lat=37.7833 lng=-122.4167 zoom=12 as |context|}}
  {{g-map-marker context lat=37.7933 lng=-122.4167}}
  {{#g-map-marker context lat=37.7833 lng=-122.4267 as |markerContext|}}
    {{#g-map-infowindow markerContext}}
      <h2>Bound Info Window</h2>
    {{/g-map-infowindow}}
  {{/g-map-marker}}
{{/g-map}}

Grouped Markers with Info Windows

Additionally you can specify parameter group which ensures that only one Info Window is open at each moment for Markers of each group.

{{#g-map lat=37.7833 lng=-122.4167 zoom=12 as |context|}}

  {{#g-map-marker context group="cats" lat=37.7833 lng=-122.4167 as |markerContext|}}
    {{#g-map-infowindow markerContext}}
      <h2>Cat #1</h2>
    {{/g-map-infowindow}}
  {{/g-map-marker}}
  {{#g-map-marker context group="cats" lat=37.7433 lng=-122.4467 as |markerContext|}}
    {{#g-map-infowindow markerContext}}
      <h2>Cat #2</h2>
    {{/g-map-infowindow}}
  {{/g-map-marker}}

  {{#g-map-marker context group="dogs" lat=37.7533 lng=-122.4167 as |markerContext|}}
    {{#g-map-infowindow markerContext}}
      <h2>Dog #1</h2>
    {{/g-map-infowindow}}
  {{/g-map-marker}}
  {{#g-map-marker context group="dogs" lat=37.7733 lng=-122.4467 as |markerContext|}}
    {{#g-map-infowindow markerContext}}
      <h2>Dog #2</h2>
    {{/g-map-infowindow}}
  {{/g-map-marker}}
{{/g-map}}

Marker bound to address query

Proxy g-map-address-marker component takes address string as parameter and translates it to lat/lng under the hood.

Optional onLocationChange action hook will send you back coordinates of the latest address search result and the raw array of google.maps.places.PlaceResult objects provided by places library.

Other optional parameters are the same as for g-map-marker. Requires places library to be specified in environment.js.

ENV['g-map'] = {
  libraries: ['places']
}

actions: {
  onLocationChangeHandler(lat, lng, results) {
    Ember.Logger.log(`lat: ${lat}, lng: ${lng}`);
    Ember.Logger.debug(results);
  }
}

{{#g-map lat=37.7833 lng=-122.4167 zoom=12 as |context|}}
  {{g-map-address-marker context address="San Francisco, Russian Hill"}}
  {{#g-map-address-marker context address="Delft, The Netherlands"}}
    {{#g-map-infowindow markerContext}}
      Works in block form too.
    {{/g-map-infowindow}}
  {{/g-map-address-marker}}

  {{g-map-address-marker context address=searchedAddress
                         onLocationChange=(action "onLocationChangeHandler")}}
  {{g-map-address-marker context address=anotherSearchedAddress
                         onLocationChange="onLocationChangeHandler"}}
{{/g-map}}

Map with route between 2 locations

Using Google Maps Directions service.

{{#g-map lat=37.7833 lng=-122.4167 zoom=12 as |context|}}
  {{g-map-route context
                originLat=37.7933 originLng=-122.4167
                destinationLat=37.7733 destinationLng=-122.4167}}
{{/g-map}}
