backbone-prototype-compatibility v1.0.5

backbone-prototype-compatibility

Why this?

Backbone uses the extend function to create models, collections, views. But this function use internally a surrogate, which does not allow the native using of JS Prototypes. With this surrogate, you can not determine an backbone object of a specific instance (the instanceof test will always failed).

This function allows your own prototypes to interact correctly with backbone by using the backbone prototypes model, collection, views.

Install

bower install backbone-prototype-compatibility --save
bower install backbone-prototype-compatibility --save

Usage

es5

function MyModel(attributes, options) {
    Backbone.Model.apply(this, arguments);
}

MyModel.prototype = Object.create(Backbone.Model, {
    property: {
        value: 10,
        enumerable: true,
        configurable: true,
        writable: true
    }
});
MyModel = compatibility(MyModel);

es6

class MyModel extends Backbone.Model {
    constructor(attributes, options) {
        this.property = 10;
        
        super(attributes, options);
    }
}

MyModel = compatibility(MyModel);

After the creation of the prototype and using the compatibility function, the prototype will contain the static methods

• compatibility ... this is the compatibility function from this repository
• extend ... this is the original Backbone.extend function, which is present on every Backbone Prototype.
