Overview About Backbone.js

What is Backbone.js?

Backbone.js is a JavaScript library with a restful JSON interface and is based on the model–view–presenter (MVP) application design paradigm.

Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.

Backbone.js is a JavaScript library that runs in the browser. We use it to structure client-side applications – those that run in a web browser.

With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server. Whenever a UI action causes an attribute of a model to change, the model triggers a "change" event; all the Views that display the model's state can be notified of the change, so that they are able to respond accordingly, re-rendering themselves with the new information.

Backbone.js is a lightweight JavaScript library that adds structure to your client-side code. It makes it easy to manage and decouple concerns in your application, leaving you with code that is more maintainable in the long term.

Developers commonly use libraries like Backbone.js to create single-page applications (SPAs). SPAs are web applications that load into the browser and then react to data changes on the client side without requiring complete page refreshes from the server.

When Do I Need A JavaScript MVC Framework?
When building a single-page application using JavaScript, whether it involves a complex user interface or is simply trying to reduce the number of HTTP requests required for new Views, you will likely find yourself inventing many of the pieces that make up an MV* framework.

Why Consider Backbone.js?
Backbone provides a minimal set of data-structuring (Models, Collections) and user interface (Views, URLs) primitives that are helpful when building dynamic applications using JavaScript. It’s not opinionated, meaning you have the freedom and flexibility to build the best experience for your web application how you see fit. You can either use the prescribed architecture it offers out of the box or extend it to meet your requirements.

What is Mustache.js?

Mustache is an open source logic-less template system developed for languages such as JavaScript, Ruby, Python, PHP, and Java.

Mustache provides templates and views as the basis for creating dynamic templates.

The main principles were:

logic-less: no explicit control flow statements, all control driven by data.
strong "separating logic from presentation": it is impossible to embed application logic in the Mustache templates.

Why mustache.js?
Mustache is a library that allows you to read in JSON formatted data and display it using templates you design with JavaScript. There are lots of similar libraries, such as underscore.js, handlebars.js, and dust.js. So why did I choose mustache?

I picked mustache because I wanted something simple. Some of the other libraries provide more functionality, but I didn’t need complexity. I needed to spend time building the site, not learning something new. And that’s the great thing about mustache.js—if you know JSON and a bit of JavaScript, it’s a cinch to implement.

Mustache is used mainly for mobile and web applications.

What is Phonegap?

PhoneGap is a free and open source framework that allows you to create mobile apps using standardized web APIs for the platforms you care about.

PhoneGap is an application framework that enables you to build natively installed applications using HTML and JavaScript.

The easiest way to think of PhoneGap is a web view container that is 100% width and 100% height, with a JavaScript programming interface that allows you to access underlying operating system features.

You build your user interface using traditional web development skills (HTML, CSS, & JavaScript), and use the PhoneGap container to deploy to different application ecosystems and devices.

When packaged for deployment, the PhoneGap application is a binary distributable file that can be distributed by the “normal” application marketplaces (iTunes, Google App Market, Amazon Market, etc…).

PhoneGap can be used to build applications that target multiple platforms, including Apple iOS, Google Android, Windows Phone, BlackBerry, HP WebOS, Symbian, and Bada.

enter image description here

Since the UI rendering engine is the mobile device’s web browser, PhoneGap applications can literally look like anything.

You can use standard HTML & CSS to make it look like a normal web page, you can use a UI framework like jQuery UI, Kendo UI, Sencha, Twitter Bootstrap, or Skeleton (or any other HTML/CSS/JS user interface framework). You can also use CSS styles/themes to make your web content look like native apps, such as iUI to mimic iOS or Android, or bbUI to mimic BlackBerry.

PhoneGap applications can have static UIs based on normal HTML, or can have dynamic & interactive experiences developed using JavaScript.

It depends upon the specific application, user experience design, target audience, and use cases to dictate how a PhoneGap application will appear.

What is Raphael?

Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web.

Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics.

This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later.

Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.

Raphaël is used by first creating an instance of the Raphaël object, which manages the creation of the canvas.

Raphaël currently supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+.

Why use Raphael.js?

It is also possible to create animations using HTML5 Canvas. HTML5 Canvas uses bitmap graphics and excels at processing complicated animations like flying past stars in outer space.

In contrast, Raphael.js uses SVG vector images and is designed to seamlessly integrate with on page events such as clicking, hovering, and dragging. Moreover, Raphael.js provides great legacy browser support (including IE7 and IE8).

How to start?

You can simply include raphael.js file in html and you will start use.

For example:

<script type="text/javascript" src = ""></script>

Full HTML Example Code

<!doctype html>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <title>Raphaël Simple Example</title>    
   <script type="text/javascript" src = ""></script>

    <!-- the html element where to put the paper -->
    <div id="paper1"></div>

    <!-- a script that create's a paper and a rectangle -->
    <script type="text/javascript">
    var paper = Raphael("paper1", 500,500);
    var rect1 = paper.rect(20,30,100,12).attr({fill: "orange"});

How to Start Angular.js & How to Extend html in Angular.js?

AngularJS is a JavaScript framework. It can be added to an HTML page with a tag.

AngularJS is a JavaScript framework. It is a library written in JavaScript.

AngularJS is distributed as a JavaScript file, and can be added to a web page with a script tag:

<script src="//"></script>

How to Start Angular.js?

When writing an AngularJS app, we write the behavior and interaction together alongside the presentation.

Writing this way can be confusing at first, especially if you have experience with other frameworks where the two are generally separate. Once you get the hang of it, it’ll become second nature.

Let’s look at the simplest app you can build with AngularJS:

Simple Example For Angular.JS

<!doctype html>
<html ng-app>
    <script src=""></script>
      <input type="text" ng-model="yourName" placeholder="Enter a name here">
      <h1>Hello, {{ yourName }}!</h1>

Output For The Above Code

enter image description here

In above text box what ever you type it will bind automatically in the header tag <h1></h1>

As you can see, you get bi-directional data binding without any work.

Bi-directional data binding means that if you change data on the back end, your changes will show up in your view automagically (actually, there’s no magic involved; we’ll get into how this works soon).

Similarly, if you change data in your view (e.g., by typing into a text box), it will automagically update your model.

So what did we do in our app?

= yourName
{{ yourName }}

First, we used our most important (and most easily forgotten) term: the ng-app attribute on the tag. Without this tag, the AngularJS process does not start.

Second, we told AngularJS that we want to set up bi-directional data binding on the yourName model on the page.

Third, we told AngularJS to display the data yourName in the directive template called {{ yourName }}.

How AngularJS Extends HTML ?

AngularJS extends HTML with ng-directives.

The ng-app directive defines an AngularJS application.

The ng-model directive binds element values (like the value of an input field) to the application.

The ng-bind directive binds application data to the HTML view.

Example Code:

<!DOCTYPE html>

<!-- Angular Directive Starts -->
<div ng-app="">

<p>Input something in the input box:</p>
<p>Name: <input type="text" ng-model="name"></p> <!-- Here ng-model binds the value of Input Filed -->
<p ng-bind="name"></p> <!-- Here binds application variable name to the innerHTML of a paragraph. -->


<script src="//"></script>


Above Code Explanation

AngularJS starts automatically when the web page has loaded.

The ng-app directive tells AngularJS that the

element is the "owner" of an AngularJS application.

The ng-model directive binds the value of the input field to the application variable name.

The ng-bind directive binds application variable name to the innerHTML of a paragraph.


Suppose,If you remove the ng-app directive, HTML will display the expression as it is, without solving it.


What is Angular.js?

AngularJS is an open-source web application framework. It is a structural framework for dynamic web apps.

It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly.

Its goal is to augment web applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

AngularJS is a MVC framework that defines numerous concepts to properly organize your web application.

Your application is defined with modules that can depend from one to the others. It enhances HTML by attaching directives to your pages with new attributes or tags and expressions in order to define very powerful templates directly in your HTML.

It also encapsulates the behavior of your application in controllers which are instanciated thanks to dependency injection.

AngularJS helps you structure and test your Javascript code very easily.

Finally, utility code can easily be factorized into services that can be injected in your controllers.

Some Main reasons for using Angular.js
1. MVC done right
2. A declarative user interface.
3.Write less code
4.DOM manipulations where they belong
5.Service providers where they belong
6.Context aware communication
7.Unit testing ready
