According to the Ember.js website, this permits you to create “ambitious” web applications.
In Ember.js, route is employed as a model, handlebar template as views and controllers manipulate the info within the model.If you would like to create a single-page web application that pushes the envelope of what’s possible on the online , Ember.js is that the right choice for you.
Figure 1.0 The structure of the first web (left) versus the promise of Ajax (middle) versus modern web application.Early websites were counting on the full-page refresh approach shown at the left in figure 1.0. With the arrival of the asynchronous call came the power to send specific parts of the web site for every response, as shown in figure 1.0 (middle).
In Ember.js, the user receives the complete website once, upon the initial request. So it increased initial load time but significantly improved performance for every subsequent user action, as shown in figure 1.0 (right).
Let’s take a better check out each of the MVC components.
· Controller layer — Built with a mixture of routes and controllers
· View layer — Built with a mixture of templates and views
· Model layer — Built with a mixture of model and ember data.
Figure 2.0 The parts that structure Ember.js and the way they slot in with the MVC pattern
Models and Ember Data
This layer is liable for any server-side communication also as model-specific tasks like format .
Ember model uses ember data to dramatically simplify your code while improving the robustness and performance of the appliance .
Controllers and the Ember Router
The layer between the model and consider is that the controller layer. There are a few of controllers, most notably the “Ember.ObjectController” and “Ember.ArrayController”.
The Ember Router is that the mechanism that updates your application URLs and listens to URL changes. Each route can have variety of sub-routes, and you’ll use the router to navigate between the states in your application.
Views and Handlebars.JS
The view layer is liable for drawing the weather on the screen. Ember.js features a sophisticated system for creating, managing and rendering a hierarchy of views that hook up with the browser’s DOM. Views are liable for responding to user events, like clicks, drags, and scrolls, also as updating the contents of the DOM when the info underlying the view changes.
Ember.js uses Handlebars.js as its template engine. Handlebars.js provides the facility necessary to allow you to build semantic templates effectively with no frustration.
Ember.js is most likely Convention over Configuration. This means that rather than writing tons of boilerplate code, Ember can automatically deduce much of the configuration itself, like automatically deciding the name of the route and the controller when defining a router resource.
Ember even increases the bar by automatically creating the controller for your resource if you never define it specifically.
Ember includes both a superb router and an optional data layer, called ember data. Unlike AngularJS and BackboneJS frameworks, which have a really minimal data layer (Backbone’s Collection/Model and Angular’s $resource), Ember comes out of the box with a full data module which integrates really nicely with a Ruby-on-Rails back-end or the other RESTful JSON API that follows an easy set of conventions.
It also provides support for fixing fixtures for developing against mock API and testing.
When it involves the planning of Ember.js, performance has been a serious goal. Concepts like The Run Loop, which ensures that updated data only causes one DOM update albeit an equivalent piece of knowledge was updated several times,
along with caching of computed properties, and therefore the ability to precompile the HandleBars templates during the build time or on your server, help to load and keep your application running fast.
AngularJS and EmberJS
AngularJS and EmberJS are similar frameworks on variety of levels, but also different in several elements.
AngularJS, for instance , will display an outsized static data set more quickly than EmberJS, but EmberJS will make it easier to feature interactivity thereto large data set and will handle changes more efficiently.
Furthermore, while both are opinionated frameworks, EmberJS takes a somewhat stronger position than AngularJS, which may make some tasks around porting an existing application challenging to finish.
In the end, either architecture has its own trade-offs, and determining which framework is true for you is just a matter of evaluating your application’s needs versus the strengths of each framework.
Best practices for real world Ember deployment
“Ember CLI” may be a instruction tool for quickly generating web apps structure. The CLI may be a very useful gizmo and can probably be the quality thanks to create ember apps within the future. Using Ember CLI slightly changes the way the app is written.
How to use Ember-CLI?
First, you’ve got to download and install “node.js” to your computer.
Once you’ve got node installed, you’ll get ember-CLI by opening up a prompt and running:
$ npm install -g ember-cli
To create a structure for the application you can run:
$ ember new project-name
This will create a folder called releases with everything needed to start coding. Change the current directory into releases and run:
$ ember server
Now you should be able to visit “http://localhost:4200” and see a very basic page.
