Best Javascript Frameworks: The top most popular javascript frameworks for Mobile and Web apps

This article will give suggestions about JavaScript frameworks, who wants to work with mobile apps, web apps or Hybrid apps using the Best JavaScript Frameworks. Developing web application with plain JavaScript is not easy to maintenance. Few years back developer where using plain JavaScript with JQuery to develop a web application, which is not very easy for maintenance.

Now a day a modern web applications are developed using modern JavaScript frameworks and the frameworks are developed using some patterns such as MVC, MVVM, MVP patterns, so it is very easy for maintenance. JavaScript Frameworks are very good in working with single page applications and Scalable, maintainable and reusable for single page application development.

Below listed frameworks are very best for developing the single page application and most popular JavaScript frameworks and Frameworks will help to develop the application for modern web apps.

AngularJS

When a developer has to build a complex website with frequent maintaining they chooses Angular platform. Angular is popular due to its extension of HTML for applications. The consequential environment is amazingly expressive, readable, and quick to develop. Angular’s acceptance is enormous, and companies using it are as miscellaneous as Domino’s Pizza, Ryanair, iTunes Connect, PayPal Checkout, Google. It is an open framework supported by Google Company.

Angular is an MVC-type framework. It offers reciprocal data binding among models and views. This data binding allows for an automatic update on both sides whenever there is a data change. This is remarkable because it excludes DOM manipulation from the list of things you have to consent about them. It allow the user to build reusable View Components. It provides a facilities framework to allow easily backend and frontend server communication.

AngularJS is a toolset is structured framework for most suitable application development. It is completely extensible and works well with other libraries. Each and every feature can be modified or replaced according to need of your application.

Controllers are the conduct behind the DOM elements. AngularJS express the behavior in a clean readable form without the usual boilerplate (HTML5 front-end template) of updating the DOM, registering callbacks or watching model changes. AngularJS provides integral services on top of XHR (XMLHttpRequest) as well as various other back-ends using third party libraries.

Client-side form validation is an essential part of abundant user experience. AngularJS state the validation rules of the form without having to write JavaScript code. We have write the less code in AngularJS framework for forms.

Directives is an exceptional and powerful feature available only in Angular. Directives let you invent new HTML syntax, according to your application. Directives is used to create reusable components. A component allows you to hide complex DOM structure, CSS, and behavior. This lets you emphasis on either what the application does or how the application appearances looks separately.

The most important part of application development is localization. Angular’s locale alert filters and stemming directives to build blocks to make application available in all locales. The dependency injection in AngularJS allows to declaratively describing how application is bound. This means that application needs nomain() method which is usually an unmanageable confusion. Dependency injection is also a primary to AngularJS. This means that any component that does not suitable according to your needs can easily be replaced.

BackboneJS

Backbone is a well simple framework that turns into a single JavaScript file. Backbone has been around for a while; developed by Jeremy Ashkenas from CoffeeScript and Underscore fame. Backbone is particularly popular with developers looking for a simple building for their small web applications without bringing in a large framework like Angular or Ember.

Backbone offers a full MVC framework along with routing. The Models allow for key value binding and events for management data changes. When a model’s contents or state is changed, other objects that have contributed to the model are informed so they can continue accordingly. Here, the views follow to changes in the model, and update themselves accordingly instead of the model having to deal with the views manually.

Backbone distributes with a number of very beneficial functions for handling and working with your data. Unlike other implementation, arrays in JavaScript are fixed, which really a hampering problem is when you have to deal with data.

The Views have declarative event management, and the Router does an excellent job of handling your URL and state management. Everything you need to build a Single Page Application without offering too much and without unnecessary complexity.

Models (and Collections) can connect to RESTful APIs. However, the default technique is to use a standard AJAX call when you want to communicate to the server, you can easily switch it out to anything you need. A number of adapters have sprung up covering most of the favorites including Websockets and local storage.

Backbone consist of 4 major classes

• Model
• Collection
• View
• Controller

Models can mean different things in different implementations of MVC. In Backbone, a model represents a singular entity, a record in a database. However, there are no hard and fast rules. Models are the main key of any JS application, which consist of interactive date and large set of logics. The model merely gives you a way to read and write arbitrary properties or attributes on a data set.

Collections in Backbone are basically just a collection of models. Going with our database similarity from earlier, collections are the results of a request where the results consists of a number of records [models].

Views in Backbone can be somewhat unclear at first squint. To MVC traditionalists, they resemble a controller rather than a view itself. A view handles two responsibilities essentially:

Follow to events given by the DOM and models/collections.

Represent the application’s state and data model to the user.

Controllers in Backbone fundamentally let you create bookmarkable, stateful applications by using hash-bangs. This is very acquainted to routing in traditional server side MVC frameworks. For example, games will map to the games function while the URL in the browser itself will be domain/#! /games. Through intellectual use of hashbangs, you can create applications that are severely JS based but also bookmarkable.

ReactJS

React is last year has chosen JavaScript project! Everyone seemed to be talking about ReactJS. React is open-source and developed mostly by Facebook with contributions from other major tech companies. React describes itself as a JavaScript library for building user interfaces.

React is the new JS framework from the people at Facebook, will force you to reconsideration, how you decompose the User interfaces and interactions of your application. The latest version of React is 0.4.1. React is astonishingly easy and effective model for building JS applications.

The MVC (Model-View-Controller) design pattern is fundamental to User interface development, not just in web apps, but also in frontend applications on any platform. In case of web apps, the DOM is the representation of a View. The DOM itself is produced from a written html template that is drawn from a different folder, script block or a precompiled template function. The View is an entity that carries the written template to life as a DOM fragment. It also sets up event handlers and takes care of manipulating the DOM tree as part of its development.

For the View to be valuable, it needs to display some data, and perhaps allow user interaction. The data is the Model, which comes from some data source (a database, web-service, local-storage, etc.). Frameworks offer a method of “binding” the data to the view, such that changes in data are automatically mirrored with changes on the view. This automatic process is called data binding and there are APIs/techniques to make this as whole as possible.

The MVC trio is completed by the Controller, which involves the View, the Model and orchestrates the flow of data (Model) into the View and user-events out from the View, probably leading to changes in the Model.

With React, the View part of the MVC trio takes importance and is moved into an entity called the Component. The Component maintains an absolute property bag called props, and a state that represents the user driven state of the User Interface. The view group part of the Component is slightly exciting and possibly the reason that makes React stand out compared to other frameworks. Instead of building a physical DOM directly from a template file/script/function, the Component produces a midway DOM that is a stand in for the real HTML DOM. A supplementary step is then taken to translate this midway DOM into the real HTML DOM.

As part of the midway DOM group, the Component also ascribes event handlers and binds the data limited in props and state.

If the idea of a midway DOM sounds a little alien, do not be too worried. You have already seen this approach adopted by language runtimes (aka Virtual Machines) for interpreted languages. Our very own JavaScript runtime, first generates an midway representation before spitting out the native code. This is also true for other VM based languages such as Java, C#, Ruby, Python, etc.

React cleverly accepts this approach to generate an midway DOM before producing the final HTML DOM. The midway DOM is just a JavaScript object graph and is not rendered directly. A translation step generates the real DOM. This is the underlying technique that makes React do fast DOM manipulations.

ExtJS

Ext JS is a general JavaScript framework that deliver ironic user interface for structure web applications with cross browser functionality. Ext JS is used for generating desktop applications It supports all the modern browsers as IE6+, FF, Chrome, safari 6+, opera 12+ etc. Whereas another product of Sencha, Sencha touch is used for mobile applications.

Ext JS is built on MVC/ MVVM construction. The current version of Ext JS 6 is a solitary platform that can be cast-off for both desktop and mobile application without having different code for different platform.

These are the emphasized features of Ext JS

• Customizable user interface widgets with gathering of huge user interface such as Grids, pivot grids, forms, charts, trees.
• Code compatibility of current versions with the older one.
• Flexible layout manager assistances to establish the display of data and content across multiple browsers, devices, and screen sizes.
• Advance data package decouples the user interface widgets from the data layer. The data package allows client-side gathering of data using highly practical representations, which enable features such as sorting and filtering.
• It is protocol doubting, and can access data from any backend foundation.
• Customizable Themes Ext JS widgets are obtainable in numerous themes that are reliable crossways stages.

EmberJS

EmberJS is also a powerful MVC JavaScript framework. Yehuda Katz initially released ember in 2011 as open source JavaScript framework under MIT license. EmberJS participates with the likes of Angular and React when it comes to construction interactive frontend user interfaces and has a very energetic community of developers.

Ember also have the principal two way of data binding like AngularJS, , keeping both in sync all of the time i.e. update the view when model changes and update model when the view changes.

Ember objects the best of both AngularJS (two-way data binding) and ReactJS (server side rendering). The technique Ember community continues to power it with awesome features.

Ember creates Handlebars templates better, by guaranteeing your HTML stays latest when the original model changes. To get started, you do not even have to write any JavaScript.

Involvement the future of the web platform today with Ember’s components. Components allow user to create their own required application HTML tags, using Handlebars to label their markup and JavaScript to implement tradition behavior.

Ember.js excludes the boilerplate of displaying JSON regained from server. If user knows how to use jQuery, they know how to fetch models in Ember.

Build JavaScript application that do not break the web! Ember.js makes it absolute simple to create urbane, multiple page JavaScript applications with great URL support, in a segment of the code user would write in other frameworks.

Ember manages to be between the top JavaScript Frameworks by uninterruptedly establishment itself with innovative superpowers. It is coming up with Fastboot.js module that allows server side rendering of DOM, the concept similar to what React is already using for better performance in complex User interface rendering.

AureliaJS

AureliaJS is the creation of Rob Eisenberg and team who come mostly from the world of Angular and Durandal. Aurelia though is Durandal Inc., a startup company that creates libraries, tools and frameworks to support next generation of web development, officially manages an open source product.

Aurelia is released, in January 2015, and is ready for making use. It extends the competences of Durandal and is term as NextGen version of it by Eisenberg. For the existing developers who work in Durandal or Angular1 and 2, Aurelia comes with a clear movement path.

AureliaJS is new in market but if you are evaluating a JavaScript Framework, it definitely needs a consideration. It is managed by highly professional community and carries a great legacy.

An influence fact about AureliaJS is that it is highly modularized and comprises of many independent small libraries. One can use entire framework in the project, use few of the required libraries, or extend the selected libraries to create custom framework.

Aurelia is independent package and does not have any external dependencies except for polyfills.

Features included in Aurelia.js is

Two-Way Data binding:

Their technology enables powerful two-way binding to any object. By using adaptive methods, user can select the most effective way to observe each property in their model and automatically synchronize their user interface with best performance.

Extensible HTML:

Aurelia’s extensible HTML compiler lets user create custom HTML elements, add custom attributes to existing elements and control template generation, all with full support for dynamic loading, data binding and high-performance batched rendering.

Routing & UI Composition:

Power their advanced client side router with its pluggable pipeline, dynamic route patterns, child routers and asynchronous screen activation.

MV* with Conventions:

Who wants to waste time writing tons of configuration code for their MV* architecture? Simply leverage conventions to make constructing user application effortless. Plug in your own or drop them altogether.

MeteorJS

MeteorJS is the amazingly full piled platform for building end-to-end mobile and web applications completely in JavaScript at quick speed. MeteorJS is the power player and comes prepared with all the features user need for frontend execution, backend building, business logic and database management.

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

Ever since its release, the MeteorJS network has grown massive at rapid pace and the community too is lively and cooperative. User would find loads of resources, tutorials and custom packages that give super powers to MeteorJS.

The best thing about MeteorJS is that user use only JavaScript for front end application development, no need to waste time learning anything else. Meteor.JS is modular and the packages and libraries can be used on demand.

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

From Performance viewpoint, any changes in the database are imitated back on the user interface in the real time and vice versa without the handshake between different languages or without major overhead of server response times.

MongoDB collections in Meteor: At its essential, a web application offers its users a view into, and a way to modify, a persistent set of data. Whether managing a list of to-do’s, or ordering a car to pick you up, you are interacting with a permanent but constantly changing data layer. In Meteor, that data layer is typically stored in MongoDB. A set of related data in MongoDB is referred to as a “collection”. In Meteor, you access MongoDB through collections, making them the primary persistence mechanism for your app data.

Meteor works on the principle of data on the wire, where the server does not reflect in terms of URLs or HTML pages. The client application interconnects with the server over DDP. Typically, as an application loads, it initializes a series of subscriptions that fetch the data required to render the application. As the user interacts with the application, different subscriptions may load, but there is no technical need for URLs to be involved in this process user could easily have a Meteor application where the URL never changes.

PolymerJS

Polymer.js is a dissimilar game altogether. Google released polymer back in 2013. Polymer uses the idea of web components to extend HTML capabilities.

Web Components is the browser technology released by W3C using which new custom HTML elements can be created. For example <audio> is a standard HTML5 element but with the web components and related technologies you can create your own custom element – like <my-audio>.

Polymer gives powers and brings structure in building custom HTML elements using browser based technologies that includes web components.

Polymer is a trivial library that helps user can take full advantage of Web Components. With Web Components, user can create reusable convention elements that interoperate flawlessly with the browser’s integral elements or break user’s application up into correct components, making user’s code cleaner and less expensive to maintain. Polymer scatterings a bit of sugar over the typical Web Components APIs, making it easier for user to get great results.

Polymer App Toolbox helps user to build and deliver cutting-edge Progressive Web Apps with negligible overhead and payload, by leveraging influential web platform features like Web Components, Service Worker and HTTP/2. The Toolbox provides a component-based architecture, responsive layouts, a modular router, localization support, turnkey support for local storage and offline caching, and efficient delivery of unbundled app resources. Adopt these features individually, or use them together to build a full-featured Progressive Web Applications

KnockoutJS

Steve Sanderson initially released KnockoutJS in 2010 as open source JavaScript Framework under MIT license. Knockout build under the MVVM design model and that makes it a little different from Ember and Angular.

Knockout has had its golden time but as of now, it is growing at a much slower pace as compared to the earlier competitors like Angular, Ember or Backbone. The slow growth is simply because it lags way behind in terms of improvements and adding more features.

Developer community is slowly moving to frameworks like React and Angular. Knockout has a great legacy and can definitely make a comeback but only if someone else adopts it and starts development it with the latest and greatest of the world of JavaScript technologies.

Features of knockout are listed below:

Elegant dependency tracking

automatically updates the right parts of user interface whenever user data model changes.

Declarative bindings

a simple and obvious way to connect parts of user interface to their data model. They can build a complex dynamic user interface easily using randomly nested binding contexts.

Trivially extensible

implement tradition behaviors as new declarative bindings for easy reuse in just a few lines of code.

Declarative bonding which makes user easily associate DOM element with model data using a concise and readable syntax. Automatic user interface refresh let user data model’s state changes, the user interface updates automatically. Tracking dependency obliquely set up chains of relationships between model data, to transform and combine it. Templating Rapidly generate cultured, nested user interface as a function of user model data.

VueJS

Evan you creates vue.Js in 2014 as open source framework for public use under MIT license.

VueJs is relatively new and is gaining lot of traction among the community of developers. VueJs works with MVVM design paradigm and has a very simple API. VueJs demonstrate minimalism to the extreme and allows you to use selective modules, as required.

Vue is a advanced framework for building user interfaces. Unlike other huge frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is motivated on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. Vue is also flawlessly capable of powering cultured Single Page Applications when used in combination with modern tooling and supporting libraries.

Vue is inspired by AngularJS, ReactiveJs, knockoutJS and RivetsJS and updates model and view via two-way data binding.

While Vue is not in the league of Angular or Ember but conceptually has all the potential to be the JavaScript framework of future and hold respectable market share. It is holding the ground firmly after 10 months of its release and getting regular updates by the creator, Evan You.

The component system is another significant concept in Vue, because it is a concept that permits user to build large scale applications composed of small, self-contained, and often reusable components. If we think about it, almost any type of application interface can be preoccupied into a tree of components.

NodeJS

Node.js is a server-side platform constructed on Google Chrome’s JavaScript Engine (V8 Engine). Ryan Dahl developed node.js in 2009 and its latest version is v0.10.36, under MIT license

Node.js is an open source, cross-platform runtime environment for implementing server-side and networking applications. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux. Node.js also provides a hugh library of various JavaScript modules which shortens the development of web applications using Node.js to a great extent.

Features of Node.js:

Asynchronous and Event Driven:

All APIs of Node.js library are asynchronous, that is, non-blocking. It fundamentally means a Node.js based server never waits for an API to return data. The server changes to the next API after calling it and an announcement device of Events of Node.js helps the server to get a reply from the previous API call.

Very fast being built on Google Chrome’s V8 JavaScript Engine:

Node.js library is very fast in code execution.

Single Threaded but Highly Scalable:

Node.js uses a single threaded model with event looping. Event device helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers that create limited threads to handle requests. Node.js uses a single threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server.

No Buffering:

Node.js applications never buffer any data. These applications simply output the data in chunks.

JXcore is a branch of Node.js directing mobile devices and internet of things (IoTs). Its first beta was released in January 2014. It was open source on February 13, 2015 and made accessible through a GitHub repository. JXcore can use either of the Google V8 or Mozilla SpiderMonkey JavaScript engines. As a result, JXcore can run Node applications on iOS devices using SpiderMonkey. As of March 25, 2016, active development on JXcore has been ceased.

Node.js can be used in following area:

• I/O bound Applications
• Data Streaming Applications
• Data Intensive Real-time Applications (DIRT)
• JSON APIs based Applications
• Single Page Application
