nodejs 8.0 release.png

The long wait for Node.js Version 8.0 release finally ended on May 30 (12 PM PST), after a delay of almost a month. The new Node.js release brings a lot of new features and fixes for developers in order to significantly improve debugging and developer workflow. Carbon is the codename of the new Node.js release, which removes version 7 from the Node.js current release line. Node.js Version 8.0 will also become the current LTS version from October 2017 and will be maintained till December 31, 2019. Read this blog to gain insight into why this release of Node.js is big for Node.js users.

Important Features of Node.js Version 8.0 Release

TurboFan & Ignition

The introduction of TurboFan and Ignition is the the biggest change Node.js users will see in the latest release. TurboFan is the optimizing compiler and Ignition is V8’s interpreter. Daniel Clifford and the V8 team say, “The combined Ignition and TurboFan pipeline has been in development for almost 3½ years. It represents the culmination of the collective insight that the V8 team has gleaned from measuring real-world JavaScript performance and carefully considering the shortcomings of Full-codegen and Crankshaft. It is a foundation with which we will be able to continue to optimize the entirety of the JavaScript language for years to come.”

The addition of V8 5.8 in the latest release is another advantage for developers. V8 5.9 is also scheduled to be released in early June.

Note: V8 5.8 is ABI (Application Binary Interface ) compatible to 5.9.

Node.js 8.0 Comes With npm 5

With Node.js 8.0, users will also get access to npm 5.0.0, which will save by default now. In npm 5, package-lock.json will be automatically created unless an npm-shrinkwrap.json exists. Besides, when there is no internet connectivity, there’s no need to retry network requests. Another important change is that npm 5 will install the packages from the latest registry you have switched to. For example, if you generated your package lock against registry A, and switch to Registry B, npm will pick Registry B to install the packages, not Registry A.

Node.js API (N-API)

The Node Foundation says that Node.js API (N-API) will be added in the new release as an experimental feature. The top reason behind adding N-API in the Node.js 8.0 is to ensure that addons are not influenced by changes in the underlying JavaScript engine. As a result, there will be no hassle of recompilation while running native add-ons with different Node.js versions. Not only this, native addons can also work with Microsoft's Chakra-Core runtime as well.

The New URL Implementation

With Node.js 8.0, the WHATWG URL implementation is now a fully supported, non-experimental API within Node.js. The advantage of the new URL implementation is that it matches the URL implementation and API available in modern Web Browsers like Chrome, Firefox, Edge, and Safari. So, code consisting of URLs can be easily shared across environments.

New Tracing and Async Features

Node.js 8.0 comes with upgraded experimental async_hooks module (formerly async_wrap). With the help of this diagnostics API, developers will now be able to effectively track the operation of the Node.js event loop and keep a check on asynchronous requests.

Significant Changes to Buffer API within Node.js

One of the most important changes to the Buffer API within Node.js is the return of a zero-filled Buffer instance whenever the deprecated Buffer(num) constructor (with or without the new keyword) is called. The problem with previous Node.js versions was the return of uninitialized memory, which was likely to contain potentially sensitive data.

Console Changes

Previously, writing console output to the underlying stream often resulted in Node.js application crash. But that’s not the case with Node.js 8.0 as it ignores such errors. So, the use of console.log and the other APIs will be much safer now.

Debugger changes

Node.js 8.0 comes without the legacy command line debugger. The direct integration of node-inspect into the Node.js runtime is meant for command line replacement. Besides, the V8 Inspector debugger (first introduced in Node.js 6.0 as an experimental feature) has been upgraded to a fully supported feature.

New JavaScript API for Inspector Protocol

Node.js 8.0 also sees the introduction of a new experimental JavaScript API for the Inspector protocol. This feature will pave the way for developers to make better use of the debug protocol to inspect running Node.js processes.

Above are the most important features and fixes that are going to be introduced in Node.js 8.0. I will explain the features in more details once the latest release is out for sometime. I hope the blog helps you understand what Node.js 8.0 has in store for you.

JavaScript, the most commonly used language around the globe, continues 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 assess 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 future development project.

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 Seven JavaScript Frameworks/Libraries to Look For

#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.

#7 Aurelia.io

Untitled Design (3).png

Aurelia.io, an open-source framework under MIT license, is also a new framework, officially announced January 26th, 2015, two years ago. The stable release of Aurelia.io came out in mid-2016 and it’s popularity has been on a significant rise ever since. Aurelia.io is fast and lightweight. Aurelia supports one-way data-binding and two-way data-binding. It even allows custom data binding with Angular syntax.

The reactive system of Aurelia delivers top notch performance which is much better than DOM-diffing, a major reason behind blazingly fast speed of Aurelia. The size of Aurelia is small and it also allows developers to further reduce its size by removing modules, lazy loading bundles, code splitting and more.

Aurelia enables developers to build applications using Javascript (ES5, ES2015), TypeScript or even something like CoffeeScript. Since Aurelia leans on ECMAScript 2016, it provides developers access to native modules, classes, decorators and many more. What makes Aurelia unique is the capability to build components using plain JavaScript, making your code clean and easy to evolve over time. Aurelia is highly modular and designed keeping in mind extensibility so that developers feel less burdened.

Aurelia can integrate with many third party libraries or frameworks as well, including jQuery, React, Polymer, Bootstrap, MaterializeCSS. Besides, the framework supports ES5, ES2015, ES2016 and Typescript, paving the way for high flexibility. Aurelia also has a very large community to keep it making better, with the support of numerous contributors and a big core team.

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.

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.
