Introduction

Mapping applications occupy their own niche within the broader web development ecosystem, and ambitious web maps demand an framework like EmberJS.

MapboxGL, a powerful GL engine for beautiful web maps, and ember-mapbox-gl, a bindings addon for EmberJS and Mapbox, lay the groundwork for ambitious web mapping applications, but leave gaps in:

  1. Layer composition
  2. Complex source management
  3. State and the Single Source of Truth principle

This addon fills those gaps by providing a few components and models:

  • {{labs-layers}} (component)
  • layer-group (model)
  • layer (model)
  • source (model)

These chiefly allow for "config-driven" map applications, where "adding a layer" to an interactive map with numerous layers is as simple as adding a new entry in a JSON definition.

Data Schema

This addon uses an opinionated data schema to allow for layer composition and source management. Generally, layer-groups use the following data scheme:

[
  // layer group
  "id": "aerials",
  // ...
  "layers": [
    {
      // layers
    }
  ]
]

Here's an example of a full JSON response for layer-groups:
