Ember-Leaflet aims to make working with Leaflet layers in your Ember app as easy, declarative and composable as templates make working with DOM.

Ember Leaflet works in Ember 1.13.9+ with no deprecations.

To install it run:

ember install ember-leaflet

Documentation and examples are hosted at www.ember-leaflet.com. Please file any issues if you see that something can be improved.

If you're looking for the previous ember-leaflet version, you can use this repo.

In your ember-cli-build.js add the following snippet:

  var app = new EmberApp(defaults, {
    // Add options here
    fingerprint: {
      exclude: [
        'images/layers-2x.png',
        'images/layers.png',
        'images/marker-icon-2x.png',
        'images/marker-icon.png',
        'images/marker-shadow.png'
      ]
    }
  });

Ember-Cli does fingerprinting (appending an md5 checksum to the end of every file) for production builds by default (http://ember-cli.com/user-guide/#fingerprinting-and-cdn-urls). Exclude the assets you need so that your production build produces them correctly.

Web apps frequently need to display geographic data, especially if it has a direct relationship with the real world. That isn't new, and has been done previously in all kinds of formats, particularly with raster and vector data.

Ember apps naturally may have the same requirements and until now, devs have been either using mapping libraries outside of ember scope, or using previous versions of ember-leaflet.

The problem was that both approaches were hard. Frequently existing libraries have regular javascript imperative APIs and html in mind. We all know and love how ember makes us flow the data in our app. Previous approaches simply didn't fit where ember really shines: templates, actions, routing, and above all, expressiveness.

Ember-leaflet allows you to express your maps right in your templates. Also, it is streamlined for ember in general. You have things like actions, components and the ability to use regular handlebars helpers like {{#if or {{#each.

We can't go wrong with delegating the mapping part to the battle tested, performant and lightweight Leaflet library.

So, let the mapping begin.

Think of your map as a set of layers inside a container. Your main container will be the component {{leaflet-map}}. This component creates the map container where your tiles, vectors and markers will be added to. Let's see an example of how it looks:

{{#leaflet-map lat=lat lng=lng zoom=zoom as |layers|}}

  {{layers.tile url="http://{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}.png"}}

  {{#layers.marker location=emberConfLocation as |marker|}}
    {{#marker.popup}}
      <h3>The Oregon Convention Center</h3>
      777 NE Martin Luther King Jr Blvd<br>
      Portland, OR 97232
    {{/marker.popup}}
  {{/layers.marker}}

  {{#layers.marker location=hotel as |marker|}}
    {{#marker.popup}}
      <h3>Hotel</h3>
    {{/marker.popup}}
  {{/layers.marker}}

{{/leaflet-map}}
