Backbone Despotism

A Backbone replacement model that enforces property declarations. Exposes a model called Backbone.StrictModel.

Creating a model with a properties definition

var MyStrictModel = Backbone.StrictModel.extend({
  props: {
    "name": Backbone.StrictModel.type.STRING,
    "count": {
      "type": Backbone.StrictModel.type.NUMBER
    }
  }
});

var myStrictModelInstance = new MyStrictModel();

myStrictModelInstance.set("monkey", "banana"); // Will be ignored
myStrictModelInstance.set("name", 43); // Will be ignored
myStrictModelInstance.set("count", 43); // Will be set
myStrictModelInstance.set({
  "name": "Gustaf",
  "count": 12,
  "animal": "monkey"
}); // Will set `name` and `count` but will ignore `type`

Types

The available types is:

Backbone.StrictModel.type.STRING
Backbone.StrictModel.type.NUMBER
Backbone.StrictModel.type.BOOLEAN
Backbone.StrictModel.type.OBJECT // Everything else like arrays and structs

Using data mappings

You can use data mappings to rename properties on model.set.

Example:

var MyStrictModel = Backbone.StrictModel.extend({
  props: {
    "name": {
      "type": Backbone.StrictModel.type.STRING,
      "foreignKey": "firstName"
    }
  }
});

In the example above, doing new MyStrictModel({ firstName: "Göran" }, { useForeignKeys: true }) will result in a model with { "name": "Göran" }.
