v4

[hilljh82]

v4 will be a major update to the code base. It is expected to break existing code bases, and we will not provide support for backwards compatibility. The list below is a list of features we plan on putting in v4. As we work on the update, expect this list to change.

Proposed Features

• [x] Upgrade code base to use ES6 via core-object
  • [x] Create Listener object and LegacyListener object for porting existing listeners
  • [x] Create Controller object and LegacyController object for porting existing controllers
  • [x] Create Router object and LegacyRouter object for porting existing routers
  • [x] Create Policy object and LegacyPolicy object for porting existing policies
  • [x] Move listener objects to their own module
• [x] Create Service abstraction for objects that live the entire life of the application outside of existing object types.
• [x] Improve inheritance support in library classes
• [x] Add support for synchronous messaging
• [x] Improve testing infrastructure for Blueprint modules
• [x] Switch from callback architecture to Promise architecture
• [x] Prepend blueprint. to built-in message types
• [x] Replace underscore with lodash

General Tasks

• [x] Update test cases

We are making good progress on v4. Our next steps involve updating the examples to make sure v4 meets our design expectations.

We have some major developments. After studying core-objects and EmberJS, we were able to implement a similar object model in Blueprint. This means that we can have class that emulate polymorphism and use mixins to increase reuse of behaviors.

In addition to the previous comment, we now have the ability to bind services and models to object properties. This means that we no longer have to manually import a model. Instead, we can reference it via its string property. For example, here is how you can bind a service and model to a controller definition:

module.exports = Controller.extend ({
  shoppingCart: service ('shopping-cart'),
  person: model ()
});

v4 is complete, and is now released.
