EXTINGUISH THE FIRE WITH EMBER.JS BTVWAG - Feb 12, 2014
Presented by Peter Brown
WEB DEVELOPER @beerlington
PROBLEMS ‣ Client side development is challenging ‣ Expectations about
how websites should work ‣ Single page applications aren’t always that ‣ Lack of conventions
HYPOTHESIS As browsers become more capable and JS enables us
to do more, the applications we build will become more ambitious and require better tools. Complexity Capability
A framework for creating ambitious web applications Write dramatically less
code Built for productivity Don't reinvent the wheel EMBER.JS
WHAT DOES EMBER LOOK LIKE?
ROUTER Maps a URL to a Route App.Router.map(function() {! this.resource('posts');!
this.resource('post', { path: '/post/:post_id' });! });!
ROUTER /posts → PostsRoute /post/123 → PostRoute App.Router.map(function() {! this.resource('posts');!
this.resource('post', { path: '/post/:post_id' });! });!
ROUTER Nested Routes App.Router.map(function() {! this.resource('post', { path: '/post/:post_id' },
function() {! this.route('edit');! this.resource('comments', function() {! this.route('new');! });! });! });!
ROUTER /post/123 → PostRoute /post/123/edit → PostEditRoute /post/123comments → CommentsRoute
/post/123/comments/new → CommentsNewRoute App.Router.map(function() {! this.resource('post', { path: '/post/:post_id' }, function() {! this.route('edit');! this.resource('comments', function() {! this.route('new');! });! });! });!
ROUTE Responsible for loading data, displaying templates and setting up
application state. App.PostRoute = Ember.Route.extend({! model: function(params) {! return this.store.find('post', params.post_id);! }! });!
CONTROLLER Acts as a proxy to the model and handles
events from the template App.PostController = Ember.ObjectController.extend({! actions: {! publishPost: function() {! this.toggleProperty('isPublished');! }! }! });!
TEMPLATE Handlebars = HTML + embedded expressions Hello, <strong>{{firstName}}</strong>!!
TEMPLATE Hello, App.ApplicationController = Ember.Controller.extend({! firstName: "Peter"! });! The PostRoute
“glues” these together
TEMPLATE Automatically bound to controller’s state {{#if isPublished}}! <span>! This
post is published!! </span>! {{else}}! <span>! This post is NOT published!! </span>! {{/if}}!
MODEL Defines schema and relationships App.Post = DS.Model.extend({! title: DS.attr('string'),!
publishedAt: DS.attr('date'),! author: DS.belongsTo('author')! });!
VIEW When you need more control, used less frequently, always
associated with a controller var view = Ember.View.create({! templateName: 'say-hello',! name: "Bob"! });!
COMPONENT Custom HTML elements, like views without controller <script type="text/x-handlebars"
id="components/blog-post">! <h1>Blog Post</h1>! <p>Lorem ipsum dolor sit amet.</p>! </script>!
DATA AND EVENT RELATIONSHIPS
DATA BINDING Route View Model Controller Template
EVENT BUBBLING View Model Controller Template Route
UPDATING DATA View Controller Template Model Route
EMBER’S ADVANTAGES
ARCHITECTURE ‣ Supports application growth via: • Organization • Eliminating
boilerplate • Sensible conventions ‣ Encapsulation • Loose coupling between components
APPLICATION SPEED ‣ 100% of HTML rendering is in browser
‣ Server is responsible for data via API Requests
OBJECT MODEL ‣ Computed properties • with and without aggregate
data ‣ Observers ‣ Bindings • two-way default, one-way for performance
MASTER-DETAIL INTERFACE
MASTER-DETAIL INTERFACE
FRIENDLY DOCUMENTATION
RAILS INFLUENCE ‣ Convention over configuration • Naming conventions (code
+ files) • If it feels painful, you’re likely doing it wrong ‣ REST architecture
EMBER’S DISADVANTAGES
LEARNING CURVE Frustration Time
SPRINKLES OF JAVASCRIPT
HANDLEBARS
EMBER DATA BETA!
WHAT’S COMING?
EMBER DATA 1.0
BUILD TOOLS ‣ Modules as first-class citizens (ES6 modules) ‣
Built-in Bower support ‣ CLI commands • $ ember server • $ ember test
HTMLBARS ‣ Performance gains ‣ Faster Rendering (comparable to React)
‣ Will build DOM instead of strings
HTMLBARS <img {{bind-attr src=imageUrl}}> Before After <img src="{{imageUrl}}">!
OTHER FUN STUFF ‣ Slimming down the codebase ‣ Removing
jQuery dependency ‣ Continued support for IE8
