Ember + Leaflet = Fun with maps!

EmberLeaflet aims to make working with Leaflet layers in your Ember app as easy, declarative and composable as Ember's View classes make working with DOM elements.

Wherever possible, the design is analogous to Ember's View, CollectionView and ContainerView architecture. EmberLeaflet provides functionality for maps, tile layers, markers, polylines and geometry, and popups. It provides hooks wherever possible for easy extensibility into more custom Leaflet behavior.

Usage

Creating a map is just one line of code!

App.AMapView = EmberLeaflet.MapView.extend({});

Create layers and bind content declaratively in idiomatic Ember.

App.AnotherMapView = EmberLeaflet.MapView.extend({
    childLayers: [
        App.TileLayer,
        EmberLeaflet.MarkerCollectionLayer.extend({
            contentBinding: 'controller'
        })]
});

Handle events by adding functions: listeners are added and removed automatically.

App.MarkerLayer = EmberLeaflet.MarkerLayer.extend({
    click: function(e) { alert('hi!'); },
    dblclick: function(e) { alert('hi again!'); }
});

Functionality is added to classes with mixins.

App.DraggableMarker = EmberLeaflet.MarkerLayer.extend(
    EmberLeaflet.DraggableMixin, {});

Roadmap

• Better documentation
• EmberLeaflet.GeojsonLayer for automatic parsing of geojson.
• Icon and DivIcon classes for easy bindings to icon properties like className and innerHTML.
