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…Read More- New Features and Fixes May 30 Release of Node.js 8.0 brings for Developers

10 Reasons that Make Node.js a Top Choice for Web Application Development

Untitled design (3).png

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.

10 Reasons behind Skyrocketing Popularity of Node.js for Web App Development

#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… Read full post here- 10 Reasons that Make Node.js a Top Choice for Web Application Development

Top Five JavaScript Frameworks 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…Read full blog here – 5 JavaScript Frameworks to Look for in 2017

MeteorJS: A Full Stack JavaScript Development Platform

meteor-js-624x321

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…You can read full blog  here- MeteorJS: A Full Stack JavaScript Development Platform
