It often happens that a game-changing technology enters the tech market with a boom, but passes into extinction later. However, that’s certainly not the case with Node.js, which is an open source, cross-platform built on Chrome’s JavaScript runtime. Node.js was developed by Ryan Dahl in 2009, and the platform has now become an exceptional choice for real-time web application development that boosts ROI by providing a highly interactive user experience.

The best advantage of using Node.js is that developers can write JavaScript on both the client side and the server side. It’s worth mentioning that enterprises like PayPal, Yahoo, eBay, Netflix, The Mail Online, and Walmart have taken their respective businesses to fruition using Node.js. Read further to gain insight into 10 major reasons why most businesses are jumping on the Node.js-powered web app bandwagon.

#1 Expedites the Development Process

Node.js uses the V8 engine developed by Google which allows compilation of JavaScript into native machine code and fast execution. Since Node.js uses an event-driven, non-blocking I/O model, it’s very efficient and lightweight for in-memory usage and data dense real-time web applications that work on multiple devices.


With Node.js, you can execute common web application tasks very fast, like reading or writing to the database, reading and writing to network connections and reading or writing to the file system. Node.js is a blessing for developers who want to build quick, robust web applications that can effectively deal with parallel connections with increased throughput.


After LinkedIn opted for Node.js, it recorded a significant rise in its mobile traffic and also the reduction in the number of servers from 30 to 3. PayPal is another example that benefitted from Node.js. After using Node.js, PayPal saw a 35% downfall in their response time and doubled requests per second. You can run Node.js applications on multiple servers including Microsoft Windows, Mac OS X, and Unix.

#2 Excellent for Real-Time App Development

You will agree that almost every company now looks for customer information in real time. For a simple reason, a reliable access to customer information as it’s being generated paves the way for significant boost in business sales by offering users what they are actually looking for, not something random that does not interest them. And over the past few years, having a real-time web app built using Node.js has emerged as the best way to notch that up.

With Node.js, all your worries related to low-level sockets and protocols go for a walk to the moon. Using Node.js, you can build a real-time web application as fast as making a simple blog in PHP. Node.js is a good fit for multi-user real-time web apps as in games and chat apps. The multi-user function is tackled by the event loop via websocket protocol which works on TCP. It also prevents the overhead of HTTP for web development.

#3 Data Streaming

Although HTTP request and response are thought to be two isolated events, they are data streams in real. The beauty of Node.js is that it enables file processing while uploading. As a result, it saves a lot of time that goes waste in overall processing in the event of data coming in the form of streams. The same remains the case with real-time video or audio recording.

#4 Node.js is Omnipresent

JavaScript exists in both the browser and the server, thanks to Node.js for making it possible. If a company feel the need of changing the logic built for the browser to be shifted to the server, developers can do it with ease by using Node.js code migration. Though, there is not much difference in how the code written for either the browser or server runs.

#5 Allows to Use a Single Code Base for Web Applications

With Node.js, developers can automatically send and synchronize data between server and the client side as it allows developers to write JavaScript for both the server and client. Meteor, a web app framework created on top of Node.js, offers support to the same codebase for the client and the server. Any data change in the server is immediately visible on the client-side.

“Node.js is not a silver-bullet new platform that will dominate the web development world. Instead, it’s a platform that fills a particular need. Where Node really shines is in building fast, scalable network applications”, according to the web engineering company Toptal.

#6 Serves the Purpose of Proxy Server

One of the top advantages of using Node.js is that it serves as a proxy server for services with different response times or for collecting data from multiple source points.

To better understand consider this example: An enterprise has a server side application that is meant to communicate with third party resources, collect data from different sources, or store images and videos to third-party cloud services. Now, although the enterprise can use dedicated servers, Node.js is a better option in the event of non-existent infrastructure or when a solution is needed for local development.

#7 Robust Node.js Package Manager (NPM)

Node.js has a dynamic repository of dynamic tools and modules that programmers can share for app development. Node.js has thousands of thousands of modules one can use for various tasks, like files upload management, connectivity to MySQL databases or to Redis, via frameworks, template systems, and management of real-time communication with visitors.

Node.js package manager or NPM is a savior for many programmers who need to reuse a code some JavaScript developer from outside has created to solve a particular problem. NPM also allows JavaScript developers to download updates that are made to a particular code they have previously used in their applications. Even if you don’t want to reuse a code created by a JavaScript developer from outside of your organization, you can adopt the module based approach to improve synergy between your team members.

After using NPM, PayPal saw a significant rise in developer productivity. Besides, the Internet payment giant didn’t require as many developer to build an application as it required prior to using Node.js.

#8 Node.js is Excellent with Database Queries

For database queries, Node.js has an upper hand since JavaScript is used to write database queries for new NoSQL databases like MongoDB, CouchDB. It’s a big relief for developers as they don’t need to remember the syntax differences while performing the task of combining Node.js and NoSQL databases. Node.js is really a boon to real-time web apps, given the fact that the JSON stored data format allows smooth functioning without any obstacles in data conversion or mismatches.

#9 Node.js Hosting has Gone to a New Level

As Node.js has become very popular among developers, it’s hosting has gone a long way to become a big success. PaaS (Platform as a Service) service providers such as Heroku and Modulus offer support to node deployments to a single command. With Node.js hosting, you can reduce page load time by up to 50% and bring down the number of servers required to host the application.

#10 Flourished Open Source Community

Node.js is very community friendly. Having an open-source community, Node.js offers many outstanding modules to add a lot more amazing features to your web applications. For instance, Socket.io allows to deal with constant communication between the client and the server, thereby making it possible for the server to send real-time updates at the client-end side. Express.js, Koa.js, Hapi.js, Sails.js, Meteor and Derby are some other top-notch frameworks developed by the Node.js community to expedite the application development process.

The IoT community is also welcoming Node.js for embedded devices and robotics, like Cylon and Nodebots. Moreover, it has emerged as a giant player in the real-time web app development world. All the virtues of Node.js mentioned above are the major reasons why many companies now consider Node.js as a good technology for running heavy load web applications and allowing teams to move much faster in bringing their designs to life.

JavaScript, the most commonly used language around the globe, continues to to rise in popularity, making it essential for JavaScript developers to stay abreast of top frameworks available for it. However, the stint to pick the best JavaScript framework for your web development or app development project is not easy. You first need to asses your project needs and see how suitable the functionality of a particular framework is for your development project. Read this blog to know and understand top 6 JavaScript frameworks/libraries you may like to consider for your development project in 2017.

A key to remember here is that every framework/library has its pros and cons. So, based on specific requirements of your development project, you could also find one, other than these five, the best fit for your project.

Top Six JavaScript Frameworks/Libraries to Look for in 2017

#1 Angular.JS

Angular.JS, an open source framework supported by Google, is a structural framework for dynamic web apps. Angular paves the way to use HTML as a template language. It also enables developers to extend HTML's syntax, which in turn allows to express your application's components in a clear and succinct manner.

Angular is an MVC-type framework and offers two-way data binding between models and views. By the virtue of this data binding, it becomes possible to get automated updates on both the sides in an event of data change. Thus, Angular rids the need of performing the painstaking task of writing manual code for DOM manipulation.

The modern app world calls for stability, security and innovation. And this is what Angular ensures by allowing developers to combine the modern day development features with design elements. There are different versions of Angular you can use for your development project. However, the latest version, i.e. AngularJS 2.0, has gained a lot traction in quick time. The final version of Angular 2.0 was released on September 14, 2016, and is written entirely in Typescript and meets the ECMAScript 6 specification.

Angular has the biggest community of developers and is the most used JavaScript framework for developing Single Page Web Applications.

Some of the popular AngularJS websites are Google, Youtube (PS3), Sky Store, Nike, General Motors, Guardian, and Huffington Post. You can pick Angular.JS for easy code integration, readiness for unit testing and fast development pace. AngularJS also becomes a good choice when it comes to building a complex web front-end application and using a single modular framework to take care of everything.

#2 React.JS (A JavaScript Library)

React.JS, an open-source JavaScript library first released in 2013 under BSD license for building user interfaces, is maintained by Facebook, Instagram and a community of individual developers and corporations. Since React is about user interfaces, it’s mainly the V in MVC. With React.JS, developers get a component layer to ease the process of creating UI elements and combining them together. React.JS was used to build the user interface of Facebook and Instagram, which proves the efficacy of ReactJS for building dynamic & high traffic applications.

One of the greatest advantages of React.JS is virtual DOM. The library can render a virtual DOM at client side or server side and communicate back and forth. As a result, it saves expensive DOM operations and makes updates in a very client manner. React also brings the re-usability in the form of reactive components. You can also create component libraries and use across applications. Another virtue of React is JSX, which allows developers to mix HTML with Javascript.

When compared to Angular, React lacks testing simplicity and component structure. However, unlike large AngularJS applications, debugging of self-contained components of large ReactJS apps is much easier. React is an ideal framework for JavaScript developers who want a powerful View layer, and not an elaborate framework for the rest of their application.

#3 Node.JS (Not a JavaScript Framework, then What Is It?)

Node.JS is not a JavaScript framework, but JavaScript has been put into use for writing many of its basic modules. We can say that Node.JS is an open source, cross-platform runtime environment for server-side and networking applications. Node.JS is popular for non-blocking, event-driven I/O for data-intensive real-time apps that run across distributed devices.

Node.JS runs on the V8 JavaScript Engine, which is developed by Google and and operates at a super speed. The framework obviates the need of forming separate threads by using a single thread or event loop to handle all the asynchronous I/O operations. With this suite, it becomes a cakewalk to perform major actions in web applications, like reading or writing to the database, network connections or file system.

You can go for Node.JS if your project requires the creation of fast, robust network application that is capable of dealing with parallel connections with increased productivity. LinkedIn used Node.js to take care of mobile traffic and saw a reduction in number of servers from 30 to 3. Not only this, the response time of the applications increased by 20 folds. One of the most popular Node.JS applications is Socket.io, which is designed to handle constant communication between the client and the server, and allows the server to push real-time updates to clients.

#4 Vue.JS

Vue.js

, an MIT-licensed open source project, is a lightweight and easy-to-learn JavaScript library for building web interfaces. It comes with facilities like two way data binding and virtual DOM. Unlike Angular and React that often inundate developers with myriad things to develop a web app, Vue.js is simple and only calls for things that you need for effective completion of the task. Besides, Vue.js is relatively new, therefore obviates the need of acquainting yourself with its history before starting using it.

The library was first released in 2013, but not many developers took cognizance of it in web framework technology for the next two years. It was 2016 when Vue.js rose to fame and gained so much traction that it’s now seen as an alternative for even well established JavaScript libraries, such as Angular and React.

Vue.js Achievements in 2016

  • 1,531,217 NPM downloads

  • 26,000 Github Stars

  • 100,696,367 pageviews on Vuejs.org page

  • Vue.js version 2.0 launched in September 2016

  • Vue.js was 3rd most starred project in 2016 on GitHub

Vue.js team is working towards making documentations better in 2017. There will also be improvements in APIs and on-boarding experience in the Native Rendering. Testing is another area Vue team is focussing on. So, there will be more guidance in the docs and official testing utilities to allow developers to test Vue.js components at ease. Besides, Vue is likely to see better discoverability in 2017. The reason many developers are turning to Vue is that it addresses the issues of React and Angular. And, provides a way to code in a much simpler and easier manner.

#5 Meteor.JS

Meteor.JS is an open-source, full-stack, MVC-style JavaScript framework for building end to end mobile and web applications at breakneck pace. Meteor offers numerous integrations, support and features right out of the box, including frontend rendering, backend development, business logic and database management. There has been no looking back for Meteor after the first release in 2012 as an open source JavaScript framework under MIT license.

Developers recognize JavaScript as the universal scripting language in browsers on the client-side. However, with Meteor.JS, JavaScript can be used on the back-end as well, which saves a lot of time and improves efficiency. So, Meteor saves developers from the hassle of learning two different languages for frontend and backend. The official JavaScript of the Meteor platform is ECMAScript 2015 and every new Meteor project now uses it by default.

The best advantage of using Meteor.JS is that it enables development of real-time applications. No page refreshes or specific callback logic is required for Meteor apps to react to changes. Any changes in the database related to UI elements get updated on the app’s UI in real time. Meteor uses Distributed Data Protocol (or DDP) for querying and updating a server-side database.

#6 Ember.JS

Ember.JS, an open-source JavaScript web framework, is based on the Model–view–viewmodel (MVVM) pattern. Ember.JS is a nice alternative for Angular.JS and React.JS for building interactive frontend user interfaces and a single-page application (SPA). Similar to Angular, Ember also performs two way data binding. Ember’s Fastboot.js module opens doors to server side rendering of DOM.

Ember’s Router enables developers to stop breaking the web, a big problem earlier with JavaScript-based applications as they put the entire application under one URL. With Ember, URLs and a working back button are generated by default with every route you create. Besides, it’s easy to use the API.

Developers can also combine Ember with Ruby to build richer and more interactive web apps. Another advantage of using Ember is its CLI (Command Line), which provides a nice gamut of tools to remove the hassles of organizing code into modules, setting up build tools, creating mock servers for the frontend and writing common functionality in the app. Ember could be a good pick for large application ecosystems.

JavaScript Frameworks are important as they play a key role in streamlining the whole development process by removing the complexities of code structure, maintenance and design. Apart from the five that I have discussed above, there are a few other popular frameworks as well, including JQuery Mobile, Backbone.JS, Knockout.JS, Polymer.JS, and many more., that could also turn out to be a good fit for your development project. However, as I mentioned earlier, it’s paramount to assess your project needs and understand all the pros and cons before finally deciding on a JavaScript framework.

Have you ever used a JavaScript framework before? Do you want to add more to what’s already being discussed? As always, your comments are vital for all our readers, please add them in the comment box below.

Many developers use JavaScript, an object-oriented computer programming language, to create interactive effects within web browsers. The inclination towards using JavaScript increased even more after Node.js made entry in the tech market. For a simple reason, Node.js allowed server-side implementation of JavaScript, which was not possible earlier. In this blog, I am shedding light on MeteorJS, which is an open-source JavaScript web framework written using Node.js.


MeteorJS is a full-stack, MVC-style JavaScript framework for building websites and web/mobile applications. MeteorJS comes for free as it’s open source. As the name suggests, MeteorJS allows faster development of iOS, Android, and web applications by using JavaScript on the front and backend.

Key Features of MeteorJS

1. Offers a Full Stack Solution

MeteorJS is FULL STACK, thus offers numerous integrations, support and features right out of the box. The compatible parts of the stack come assembled in Meteor. Besides, every layer of its stack is powered by a default technology. However, if one is willing to go for alternatives, MeteorJS allows them to do so as well. For example, if Meteor’s default front-end framework Blaze is not a fit for your project, you can use React or Angular.js in its stead.


Meteor’s fully integrated stack up front lets developers expedite the development process. Also, several built-in features of MeteorJS facilitate the access to frontend libraries, Node.js based server and a command line tool.


An important point to note here is that ECMAScript 2015 is the official JavaScript of the Meteor platform and every new Meteor project now uses it by default.

2. Allows to Use a Single Language

MeteorJS simplifies the development process as requires the knowledge of only one language, i.e. JavaScript, for frontend, backend and database. Therefore, the framework removes the complexity of context switching between server language and JavaScript that requires installation and configuration of different libraries, module managers, APIs, drivers and more.

3. Real-Time Applications for both Desktop and Mobile


MeteorJS enables development of real-time applications right from setup to development to deployment. MeteorJS uses Distributed Data Protocol (or DDP) for querying and updating a server-side database. It also synchronizes such updates among clients.


The best part is that MeteorJS apps react to changes without the need of page refreshes or specific callback logic. So, whenever changes are made in the database that concern UI elements, they get reflected on your app’s UI in real-time.

4. Database Integration

FINAL - 3.0Launch-Infographic-v7-1.jpg

MeteorJS supports MongoDB database along with Minimongo, which is a front-end representation of MongoDB. MeteorJS refreshes the data in the UI by replicating a subset of the MongoDB database as a local “Minimongo” subset. Besides, Meteor’s Mongo API allows faster reloading of pages and easier implementation of updates.

5. Allows to Build Cross-Platform Apps


Meteor’s integration with Apache Cordova allows developers to build cross-platform apps that look and function similar to native apps. Cordova is a platform for building cross-platform apps using HTML, CSS and JavaScript. In contrast to native apps, cross-platform apps require only one codebase for separate operating systems or devices, which saves a lot of time and cost for businesses.

6. Custom Package Manager

NPM modules are compatible with MeteorJS. However, developers can also use Meteor’s own custom package manager, called Atmosphere, which holds more than 10,000 packages.


With Meteor’s built-in package, developers can handle pre-processing and custom user authentication for Email, Facebook, Twitter, Google, etc. Meteor also has packages that support popular frameworks like Backbone.js, Bootstrap and jQuery.

Some of the popular apps that are built using MeteorJS are as follows:


One of the seven principles of Meteor is "Simplicity equals productivity." MeteorJS is simple to learn, given it doesn’t require developers to rely on multiple languages. Any developer who has used JavaScript before will find MeteorJS easy to learn. Also, MeteorJS has a large active and supportive community. The Meteor Development Group (MDG) makes dedicated effort towards keeping Meteor updated and working well.


However, like every framework, MeteorJS has shortcomings too, like it only integrates with the MongoDB database. So, a developer who wants to use MySQL for their project will not be able to do so with Meteor as it does not support SQL databases as of now. However, there are 3rd party packages that integrate MySQL reactively with Meteor to some extent. For example, developers can use numtel:pg for reactive PostgreSQL support.
