Components are taking center stage in Ember 2.0. Here are some things you can do today to make the transition as smooth as possible:

Use Ember CLI
In general, replace views + controllers with components
Only use controllers at the top-level for receiving data from the route, and use Ember.Controller instead of Ember.ArrayController or Ember.ObjectController
Fetch data in your route, and set it as normal properties on your top-level controller. Export an Ember.Controller, otherwise a proxy will be generated. You can use Ember.RSVP.hash to simulate setting normal props on your controller.

Converting libraries to Ember CLI addons

In this guide we will cover two main cases:

The Ember library will assume that Ember has already ben loaded (higher in the loading order) and thus will assume it has access to the Ember API.

From a terminal run the following commands:

git clone [email protected]:emberjs/ember.js
cd ember.js
npm install
npm start

While that is running open another terminal and run the following (starting from the ember.js folder you cloned a moment ago):

	require 'open3'

	$CR = "\033[0m" # color reset
	$red = "\033[1m\033[31m"
	$green = "\033[1m\033[32m"
	$yellow = "\033[1m\033[33m"
	$blue = "\033[1m\033[34m"

	ssh_options[:forward_agent] = true
	ssh_options[:paranoid] = false

	function parse_git_branch {
	git branch --no-color 2> /dev/null \| sed -e '/^[^]/d' -e 's/ \(.*\)/(\1)/'
	}

	function proml {
	local RED="\[\033[0;31m\]"
	local LIGHT_RED="\[\033[1;31m\]"
	local YELLOW="\[\033[0;33m\]"
	local LIGHT_GREEN="\[\033[1;32m\]"
	local WHITE="\[\033[1;37m\]"

	# default vim on osx doesn't have python, ruby support or clipboard support. These configure options add all that
	# I also ran into problems using rvm ruby, had to include those libs in the LDFLAGS for vim

	# Steps:

	$ rvm install 1.9.1
	$ rvm use 1.9.1 # vim doesn't support anything higher
	$ curl ftp://ftp.vim.org/pub/vim/unix/vim-7.3.tar.bz2 \| tar xj
	$ cd vim73
	$ ./configure --with-features=huge --enable-perlinterp=yes --enable-rubyinterp=yes --enable-pythoninterp=yes --enable-multibyte

	class MyMailer < ActionMailer::Base

	def notice(user)
	# ...
	mail(to: @to, from: @from, subject: @subject) do \|format\|
	format.html { render text: @html_content }
	format.text { render text: @text_content }
	end
	end
	end

	# bash alias
	alias subl='/Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl'

	# bash function, usage: $ st -p [projectname] -opt2 -opt3
	function st() {
	if [ -n "$1" -a -n "$2" ]; then # if more than one argument
	if [ "$1" = "-p" -o "$1" = "--project" ]; then # if arg1 is -p or --project
	local projectfile="$2"
	[[ $projectfile != *.sublime-project ]] && projectfile="$2.sublime-project" # detect if arg2 already includes the ext
	if [ -e $projectfile ]; then # does project file exist?
