DELIVERING WITH EMBER.JS
They used EmberJS to build a product

“I probably had my personal moment of truth around the beginning of Doom 3's development, when it became clear that it is no longer possible to deeply understand every single part of a modern application. There is just too much...”https://raw.githubusercontent.com/ESWAT/john-carmack-plan-archive/master/by_year/johnc_plan_2007.txt

TODAY’S AGENDA
Ember.js from a business perspective
Ember.js from a developer’s perspective

Why should you care aboutEmber?
Why should you care aboutEmber?
Because getting the latest and greatest often means rewriting parts of your apps once a year, as the community abandons
existing solutions in search of improvements.
INITIAL RELEASES
MV* Frameworks
Ember’s biggest strength COMMUNITY
Core philosophy: Stability without stagnation
Identify common patterns that emerge from the web development community and roll them into a complete front-end stack.
The Ember community works hard to introduce new ideas with an eye towards migration.
This makes it easy to get started on new projects and jump into existing ones.
Core philosophy: Stability without stagnation
The direction in which the framework is taken does not depend on a particular business choice.
No Angular 2 fiasco.
Not driven by a company
AN INDUSTRY SHIFT
Components“Unidirectional data flow”Virtual DOMIsomorphic apps
The request for comments process is intended to provide a consistent and controlled path for new features to enter the framework.
Changes done via RFC
Explosion of innovation
React’s true innovation COMPONENTS** Predictable unidirectional data flow, explicit mutation, component boundaries, lack of two-way binding
Transition to 2.X- Ember CLI- ES6 Modules- Revamped components with “virtual DOM”- API simplification- and a lot more
Transition to 2.X
“Hopefully, this plan demonstrates that staying on the cutting-edge can be done without rewriting your app.
There are a huge number of Ember apps in production today, and we're looking forward to a time in the very near future where they can start to take advantage these new features.”
https://github.com/emberjs/rfcs/pull/15
Ember comes with- separation of concerns- object model (classes, inheritance, mixins)- router- observers- computed properties- isolated components- container- templating system- run loop

Ember’s release channels
Ember-cli provides- Package manager- Directory structure and file naming conventions- Build system (broccoli)- jsHint on every run- Livereload- Module system- ES6 transpilation- Generators- Test Framework- Addon system
CONVENTION OVER CONFIGURATION
Decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility.
CONVENTION OVER CONFIGURATION
A developer only needs to specify unconventional aspects of the application.
CONVENTION OVER CONFIGURATION
The combination of conventions over configuration, Glimmer, and DDAU means that Ember developers can easily find the sweet spot of having both productivity and performance.

Recap▸ We wrote some code
2 groups of components
Container Components act like the “backend of the frontend” in a way. They are “connected” to the datasource and delegate to other components for any html that is rendered on the page.

Presentational Components render HTML given some object/data

COMPUTEDPROPERTIES
Computed properties let you declare functions as properties.
It takes one or more normal properties and creates a new value.
They observe any changes made to the properties they depend on and are dynamically updated when they're called
They can be chained.

Ember Data
Ember Data is a library for managing model data in Ember.
It’s designed to be agnostic to the underlying persistence mechanism, so it works just as well with JSON APIs over HTTP as it does with streaming WebSockets or local IndexedDB storage.

Ember FastBoot
Convention over config isomorphic apps.
FastBoot works by running your Ember application in Node.js.
When a user visits your site, the initial HTML is rendered and served to the user.
ember install ember-cli-fastboot
Ember Redux
You can use Redux together with React, or with any other view library.
ember install ember-redux

It cuts out almost all boiler plate and makes many convention based decisions for you.
