Most popular JavaScript frameworks in 2016

In this modern web JavaScript is the most popular language in the web to building the web application. There are many different ways to build modern web application with JavaScript, including a lot of different tool choices, and a lot of new theory to learn.Using the JavaScript we can easily extend the functionalities and logical executions of the component.

Most of the developer are used JQuery along with JavaScript to extend the features of HTML component,but when we talk about the large application it requires more effort and complex in code to develop and the maintain a large application. JavaScript Frameworks help to build fast,interactive and scalable web applications (which includes both single page and multiple page applications).

But, unfortunately! Most programmers find it hard to decide which framework¬†they use¬†and learn. Thus, in this article, I am going to highlight the 7¬†most popular¬†JavaScript Frameworks in 2016. Let’s get started!


7 most popular JavaScript Frameworks in 2016

1. AngularJS

When we talked about javascript frameworks the first word comes in our mind is that AngularJS. AngularJS, as this is the most commonly used JavaScript Framework by javascript developers. It released in 2009, javaScript based open-source front-end framework to create web application or SPA (Single page application) mainly maintained by Google.

It supports the¬†MVC (Model‚Äďview‚Äďcontroller),MVVM (Modal-view-ViewModal) and MVW¬†(Modal-View-Whatever) design paradigm which supports standard two-way data binding. In MVW, whatever stands for ‚Äúwhatever works for you‚ÄĚ. Angular gives you the lot of flexibility to separate presentation logic from business logic and presentation state. In MVC, your data is updated on both the UI (presentation state)¬†and back-end (coding or server side) whenever it detects some changes in the engine.

As the UI components (View) are separated from the Model components, you can easily build reusable components for amazing and user-interfaces!

Recently Angular 2.0 has been released in OCT 2016, which claims to improve the speed & performance of mobile and desktop and take it further via web workers and server-side rendering. Meet huge data requirements by building data models on RxJS, Immutable.js or another push-model. Angular Loved by Millions of developers across the globe and it’s highly recommended for anyone who wants a powerful MVC framework with a strong and modern infrastructure that takes care of everything for you to build single page applications.

Angular is also planning to release Angular 4.0 then it called ‚ÄėAngular‚Äô

(Note: This is my personal favorite JavaScript Framework till date)

2. React

React (sometimes styled React.js or ReactJS) is an open-source JavaScript library which provides a view for data rendered as HTML. Components have been used typically to render React views which contain additional components specified as custom HTML tags. React gives you a trivial virtual DOM, powerful views without templates, unidirectional data flow and explicit mutation. It is very methodical in updating the HTML document when data changes; and a clean separation between components on a modern single-page application. React also support sever-side rendering with with nodejs

As your app comes into existence and develops, it’s advantageous to ensure that your components are used in right manner and React app consists of Reusable components, which makes code reuse, testing, and separation of concerns easy.

ReactJS is not only ‚ÄúV‚ÄĚ in MVC, it has stateful components, it handles mapping from input to state changes, and it renders components. I would highly recommend this Framework if you just need a front-end development Framework to build an incredibly complex and awesome UI through the power View Layers. In this sense, it does everything that an MVC does.

Apart from Facebook and Instagram, there are several companies that use React, including Whatsapp, BBC, PayPal, Netflix, Dropbox, etc.

3. Ember

Ember.js is open-source javascript frameworks like angular and react. Initially it released in 2011, 5 year ago. It has a huge active community online, so whenever  you face any problem, you can ask them.

Ember.js is based on¬†Model‚Äďview‚Äďviewmodel (MVVM)¬†design pattern, which is slightly different than MVC, In the sense that the view model is more than view and handles most if not all of the view‚Äôs display logic

For the fast server-side rendering with nodejs and adding  the animation in UI. we need to use Ember CLI addon Fastboot.js and liquid-fire.js, so the applications have extremely enhanced performance of complex UI with animation.

Ember supports Handlebars integrated templates that update the data changes automatically. It also provides routes, dependency injection, declarative two-way data binding and Custom components.

In 2015, Ember was best JavaScript Framework, competing against AngularJS and React, which should be enough to convince you about its usability and desirability in the JavaScript framework,there are several big companies who’s using ember.js Yahoo!, Zendesk, GROUPON, Yapp, MHElabs, TILDE.

I have not worked much in ember.js but as per my knowledge i¬†would highly recommended this JavaScript Framework to those who don’t necessarily need great flexibility or a large infrastructure, and just prefer to get things done for coping with deadlines.

4. Knockout.js

This JavaScript framework was initially released by Steve Sanderson in 2010 as open source under MIT license. Knockout works under the MVVM design paradigm and that makes it a little different from Ember and Angular.

Knockout has no dependencies on any other libraries and it supports all mainstream browsers like IE 6+, Firefox 3.5+, Chrome, Opera, Safari (desktop/mobile) it’s not popular as much competitors like Angular, Ember or Backbone. The slow growth is simply because of improvements and adding more features in framework.

Developer community is slowly moving to frameworks like React and Angular. Knockout has a great capability and can definitely make a come back but only if someone else adopts it and starts improvement it with the latest web JavaScript technologies.

You can read more about Knockout at knockoutjs.com.

5. Meteor.js

If you LOVE developing the website in pure javascript then MeteorJS is for you. It’s the full stack platform for building modern end to end mobile and web applications completely in JavaScript, for all environments: Application server, Web browser, and Mobile device.

Meteor is the child of Meteor Development Group, it was first released in 2012 as an open source JavaScript framework under MIT license.

Ever since its release, the MeteorJS community too is vibrant and helpful. You would find tons of resources, tutorials and custom packages that give super powers to solve your development errors and develop your app in MeteorJS.

The best thing about MeteorJS is that you use only JavaScript for front-end and backend application development, no need to invest time learning anything else.

The server side packages run in the node.js and you do not need do anything else but MeteorJS packages to access the database, all in JavaScript, this makes developer life easy for building real time web applications.

From Performance perspective, any changes in the database are reflected back on the UI in the real time and vice versa without the handshake between different languages with minimal development efforts.

You can read more about Meteor at –¬†meteor.com.

6. Vue.js

Vue.js is another¬†open-source JavaScript framework was released in 2014.¬†It supports¬†extremely simple API for developing the¬†Reactive¬†components for Modern Web Interfaces¬†Like Ember, it also uses the¬†Model‚Äďview‚Äďviewmodel (MVVM)¬†design paradigm which helpes in the simplification of the design.

The most important feature in this framework is that you can use selective modules with it for your specific needs. For example, you need to write HTML code, fetch the JSON and create a Vue instance to create the small effects that can reused!

Similar like others JavaScript Frameworks, it also uses two-way data binding to update the model and view, plus it also uses binder for communication between the view and data binder. If you thinking that is full-fledged framework to focus on it then I must say it’s not like what you thinking because it’s focuses entirely on the View Layer, so you would need to take care of other components on your own or you can use any other framework with them.

If you are familiar with AngularJS, then you will feel comfortable with this too, as it heavily incorporates the architecture of AngularJS, so many projects can be easily transferred to this Framework if you know the basics of JavaScript.

As I didn’t get chance to work with that but if you just want to get things done or gain JavaScript programming experience, or if you need to learn the nature of different JavaScript Frameworks you should try this.

7. Backbone.js

This framework¬†can be easily integrated to any third-party template engine, however, by default it has dependancy on Underscore¬†templates¬†along with¬†JQuery,¬†It has the¬†RESTful JSON¬†interface with the support of¬†MVC (Model‚Äďview‚Äďcontroller)¬†design pattern.

If you ever heard or used the famous social news networking service reddit, then you will be interested to hear that it uses the Backbone.js for several of its single-page applications. Jeremy Ashkenas who developed the Backbone.js, it has also created the Underscore templates as well as CoffeScript, so you are assured that the developer knows his stuff.

This framework provides models with key-value, views and several modules within a single bundle, so you don’t need to download the other external packages, saving you time. The source-code is available on Github, which means you can further modify it for your needs.¬†There are several big companies who‚Äôs using backbone.js 500px Web, Airbnb, Pinterest, Reddit, WordPress.com, USA Today.com,LinkedIn Mobile.


So, I have just highlighted the 7 most popular JavaScript Frameworks in this article in the hopes that it will help you choose the best JavaScript Framework for your tasks.

If you‚Äôre still having trouble to choose¬†the best JavaScript Framework for your learning or build web application for your project, then please understand the project requirement and client expectations; and if it doesn’t then just try the next one. Rest assured though that any Framework from the list will be good enough.

The best way to learn code is to write code!!!

AngularJS Starter Templete With Bootstrap

If you have not tried yet to create angularjs website then definitely this article will help you to create angularjs website with bootstrap starter template. So let’s start.

In this example i am using bootstrap “Justified¬†nav” template.


These are the following AngularJs features what we will covered with creating this template

  1. MVC(Model view Controller) Architecture
  2. Calling JSON service with factory
  3. Dependency Injection
  4. AngularUI Bootstrap
  5. Routing
  6. Directives
  7. Image Gallery with AngularJS

At the end of the article you understand what is MVC Architecture and how it works in AngularJS? | AngularJS MVC
MVC: It’s a design pattern that breaks the application into three parts Model View Controller. Using a pattern is a reusable solution but in regular javascript we organize the code differently. Another way of looking at patterns are as a templates which can be used in quite a few different scenarios.


Model is belongs to data it can be dynamic data or static which means you can get it from a database like Mongodb and you can also get data from static JSON file.

Let’s create a static JSON to defining a model. Add following lines in a data.json file.


View is displaying the data of model. For this we use double curly brackets and it is lot like using JavaScript template library (like mustache.js).

Let’s create a view, following this instruction in index.html:

  • First¬†declare¬†the¬†name¬†of¬†the¬†application¬†using¬†ng-app¬†directive.
  • Download¬†and¬†add¬†the¬†angular¬†library¬†in¬†your¬†page¬†version¬†–¬†v1.3.0-rc.5.
  • Defining¬†the¬†controller¬†name¬†using¬†ng-controller¬†directive¬†in¬†your¬†parent¬†element.

    Let’s combined the code:

In this HTML we have use ng directives to rendering the data in view.

ng-repeat: The ngRepeat directive instantiates a template once per item from a  collection. Each template instance gets its own scope, where the given  loop variable is set to the current collection item, and $index is set to  the item index or key.

ng-init: The ngInit directive allows you to evaluate an expression in the current  scope.

ng-click: The ngClick directive allows you to specify custom behavior when an   element is clicked.

ng-show: The ngShow directive shows or hides the given HTML element based on    the expression provided to the ngShow attribute.


It controls how data is retrieved and displayed to end-user. which means Controller gives you control over model and view.

Creating angular module name which we have defined in ng-app directive in HTML.

We can also defined the dependency as per the module using [] brackets. For our application we need ngRoute for routing to navigate the site. For this you have to download and include


Creating Factory in Angularjs

AngularJS provides you three ways to create a service : factory,service and provider. A factory is a simple function which allows you to add some logic before creating the object. It returns the created object.

Scope is the glue between application controller and the view. During the template linking phase the directives set up $watch expressions on the scope. The $watch allows the directives to be notified of property changes, which allows the directive to render the updated value to the DOM.

Getting started AngularJS with Liferay Portal

After reading the title of this post the first question comes in your mind is “Can we use AngularJS with Liferay?”
and my answer is yes we can. Now your thinking why AngularJS? I will give the answer of your all questions in this article.

What is AngularJS?

Angular js is open source web application development framework developed by Misko Hevery and maintained by Google. AngularJS architecture based on MVC(Model – View – Controller). MVC pattern help you to manage separately presentation, data, and logic components. server-side services are offered by Angular, like view-dependent controllers, to client-side web applications.

These are the some remarkable features:

  • HTML Declarative approach:This feature help you to declaring dynamic views in static web-applications. For your application, AngularJS facilitates you to extend HTML vocabulary. The consequential ssetting is especially expressive, readable, and quick to develop.
  • Easy Data Binding : AngularJS Two-way data binding is its most distinctive feature, and it reduces the amount of write dynamic code.
  • Reusable Components: Using AngularJS directives help you to make your component reusable.
  • Dependency Injection: You can easily inject dependencies of other modules in your web Application. Dependency injection is also a core to AngularJS.
  • End to end Integration Testing / Unit Testing:¬†While writing a code for application, we also need write test cases. Angular is designed makes testing your application easy by using dependency Injection feature that makes testing components much easier then any other frameworks. Jasmine and Karma are the testing tool which we use in angular application
  • Routing: This feature allows to make your SPA website much easier.
  • Templating: Dynamically creating and updating HTML based on templates.
  • Services: you can use server side services in angular to make your web application dynamic.

If you are thinking to develop Angular Web Application in LIferay Developer Studio then Before starting to write a code you must know how to configure AngularJS in your liferay. It’s reduce your efforts to develop and maintain your Angular Web Application in Liferay. You can also write individual portlet in AngularJS. So in this article i am going to make a Independent News List portlet with the help of JSON Array in Angular.

Creating a liferay portlet

  • Go to the package Explorer > Right click New > Select Liferay Plugin Project

See Figure 1

If you want to setup AngularJS in Liferay developer studio. Read this article

or you can directly add the AngularJs Library in your theme or You can add directly in your portlet as well.

Now start write your code in portlet main.js file.

In this article you can see how Angular makes browsers intelligent‚ÄĒ without the use of any other third party plugins.

What you Learn in this article:-

  • Examples of how to use client-side data binding to build dynamic views of data that change immediately in response to user actions.
  • See how Angular sync your data in view without the need for DOM manipulation.
  • Learn a better, easier way to create AngularJS based portlet that works independently with your application

Getting Started

AngularJS is using HTML Declarative Approach to write and extend HTML code with custom attributes and elements. It’s also helps you to in Data Binding. You have to create one pure static HTML page then examine how we can convert this HTML code into a template that angular will use to display dynamic data.

So here is Static HTML code:-

In AngularJS, the view is a magnification of the model through the HTML template so whenever we change anything in the model angular refreshes the same binding points and updates in the view.

The view component is frame by Angular from this template:


We replaced the HTML news list with the ngRepeat directive and Angular expressions:

  • The ng-repeat=”news in newslist” attribute in the
  • tag is an Angular repeater directive. The repeater tells Angular to create a
  • element for each news in the list using the
  • tag as the template.
  • The expressions wrapped in curly braces {{ }} will be replaced by the value of the expressions.

We have added a new directive, called ng-controller, which attaches a NewsListCtrl controller to the parent tag.

  • The expressions in curly braces {{ }} show bindings, which are referring to our NewsListApp model, which is set up in our NewsListCtrl controller.

Now Build your portlet. After completing successful build go to your browser open your localhost site and just drag the portlet in layout to see the result.

Note: We have specified to load Angular Module using ng-app=”NewsListApp”, where NewsListApp is the name of our module. This module will contain the NewsListCtrl.
