Looking Forward...RFC

The Road to 2.0

emberjs/rfcs/pull/15

This is not a big-bang rewrite; we will continue development on the master branch, and roll out changes incrementally on the 1.x release train. The 2.0.0 release will simply remove features that have been deprecated between now and then. Our goal is that you can move your Ember app to 2.0 incrementally, one sprint at a time.

There are shifts you can implement now

Benefit from the lessons learned which are the motivators for the upcoming evolution.

Key Changes Ahead...

Tom Dale: Ember 2.0 in Practice

The thinest, lightest most powerful Ember ever.

  • Simplifed
  • Refined
  • More powerful

Many features available today

  • All new features developed on master
  • Stability without Stagnation
  • Data Down, Actions Up
  • It's a question of mutability
  • Instead of relying on 2-way bindings, emit actions
  • There is no view, there is only component (isolated, reusable, can be reasoned about)
  • No more ObjectController or ArrayController, proxying confuses people
  • Use explicit with/each
  • Use Ember CLI today.

Robert Jackson: Ember 2.0 RFC Recap

Recap

  • Template Updates
  • Components
  • Ember CLI

Stefan Penner: The Future of Ember

Theme Simplify the mental model...

  • Actions UP Bindings DOWN
  • New Defaults
    • One-way Bindings
    • Read-only Computed Properties
  • Virtual DOM (SSR, fast boot), simple-dom
  • RIP Controllers
    • Become a Service or Component
    • Lifecycle Mismanagement
  • Routable Components

Virtal DOM

What can we do about it
