Great for manipulating pages. Not so great for building large

You can simulate an application by having the logic run
on the server, and serving a series of pages
None
500ms The problem with this is that your user interface
can only respond as fast as your server—especially bad on flaky 3G connections
Fix this by moving *all* of the logic to the
client. The client has all of the application logic and HTML templates to render in the browser.
{ name: "Christian", occupation: "Engineer" } Instead of sending HTML,
send JSON. Only request data that the client has not yet loaded. Instant response when showing data that has already been fetched.
By decoupling the user interface from the typical HTTP request/
response cycle, you can completely modify how updates are communicated to the client. WebSocket

Classes Person = Ember.Object.extend({ firstName: null, lastName: null });
Mixins Speaker = Ember.Mixin.create({ hello: function() { var first =
this.get('firstName'), last = this.get('lastName'); alert(first + " " + last + ": HELLO!") } }); Person = Ember.Object.extend(Speaker); Person.create({ firstName: "Yehuda", lastName: "Katz" }).hello();
Mixins Speaker = Ember.Mixin.create({ hello: function() { var first =
this.get('firstName'), last = this.get('lastName'); alert(first + " " + last + ": HELLO!") } }); Person = Ember.Object.extend(Speaker); Person.create({ firstName: "Yehuda", lastName: "Katz" }).hello();
Mixins + super Speaker = Ember.Mixin.create({ hello: function() { var
first = this.get('firstName'), last = this.get('lastName'); return first + " " + last + ": HELLO"; } }); Dog = Ember.Object.extend(Speaker, { hello: function() { return this._super() + " THIS IS DOG"; } }); var phil = Dog.create({ firstName: "Budweiser", lastName: "Phil", hello: function() { return this._super() + " ZAAAAAAAA"; } }); alert(phil.hello());
Computed Properties Person = Ember.Object.extend({ fullName: function() { return this.get('firstName')
+ ' ' + this.get('lastName'); }.property('firstName', 'lastName') }); var yehuda = Person.create({ firstName: "Yehuda", lastName: "Katz" }); alert(yehuda.get('fullName'));
Uniform Access
“ Bertrand Meyer Uniform Access All services offered by a
module should be available through a uniform notation, which does not betray whether they are implemented through storage or through computation.
Namespaces >> Core = Ember.Namespace.create(); >> Core.Person = Ember.Person.extend(); >>
Core.Person.toString(); => Core.Person >> Core.Person.create().toString(); => <Core.Person:ember157> No more [object Object]!
Names in Conventions App.Post = DS.Model.extend({ title: DS.attr('string'), body: DS.attr('string')
}); // vs. App.Post = DS.Model.extend({ collectionURL: "/posts", singleURL: "/post", title: DS.attr('string'), body: DS.attr('string') });

•Create a map of user actions

Why Ember?
Ember is not a throwaway weekend project or a corporate-sponsored
project. It is built by and for the Ember community, an open source project first and only.
100% Open Source Built by the Community Ember is not
a throwaway weekend project or a corporate-sponsored project. It is built by and for the Ember community, an open source project first and only.
•Manages complexity •MIT-licensed •More productive •Aggressively rolls in best practices
•Built for the long haul
As patterns solidify, we roll them in.
Sometimes we give them a little push.
