Tips for generating automatic views in Backbone without manual instantiation

Is there a more efficient way to instantiate the view rather than directly below the definition?

var BVApp = Backbone.View.extend({
    Name: 'BVApp',
    // do chonka stuff
});
$A.Class.add(new BVApp());

Answer №1

It's not possible to create a "self instantiating view" in the literal sense, as you need to instantiate it somewhere at some point. However, there are ways to achieve a similar outcome based on your specific needs. Here are two approaches to avoid explicitly instantiating your object:

  1. One option is to create a method that both instantiates and adds your view:

    $A.Class.addInstantiated = function (ObjectConstructor) {
        this.add(new ObjectConstructor());
    };
    
  2. If you're looking for a singleton and utilizing a module loader like RequireJS, you can simply return an instantiated object:

    define([], function () {
        function Foo(a) {
            // ...performs actions...
        }
    
        return new Foo();
    });
    

    This method ensures that every use of your module will reference the same instantiated object. One drawback is the lack of testability, which can be addressed by separating the uninstantiated model into one module and then creating it as a singleton in another module. For example:

    define([], function () {
        function Foo(a) {
            // ...performs actions...
        }
    
        return Foo;
    });
    
    define(['foo'], function (Foo) {
        return new Foo();
    });
