With Node.js taking over the world of programming and development, you must be wondering, why most big companies are going for Node.js development for offering flawless services to their customers?

Technology is changing every minute. People want a robust solution for increased productivity and improved performance. They wish to overcome the real-time challenges. And who wouldn’t like opting a technology which provides all these things under one platform? As soon as Node.js was made available, people went crazy for it. A large number of developers shifted to Node.js leaving other technologies behind.

So, what actually is Node.js? Let me share a few facts about Node.js with you.

Originally, Node.js is a server engine which can be edited and adjusted. It will work only after being set up. The requests are processed as an event loop. So, Node.js is essentially a runtime. It is a part of the JavaScript ecosystem which is great for app development. It can be manipulated easily along with other JS tools, UI’s and connectors. Node and JavaScript allow creating simple web servers with just a little coding.

But, there are a few myths associated with Node.js.

» Node.js is a framework
» Relies on Chrome V8 engine only
» It does not support multi-threads
» Beginner developers can’t work with Node.

The reality, however, is actually very much different. Here are a few points which will make you aware of Node.js.

» Node.js is free, open-sourced and made easily available to all the developers.

» It is cross-platformed and runs on Windows, Linux, Unix, Mac OS X, etc.

» It uses Javascript on the server :

» Node.js uses an event-driven, non-blocking I/O model. It is perfect for data-intensive real-time applications that run across distributed devices and is well organized.

» It follows isomorphism

What can Node.js do?

» Node.js makes it possible to create web servers and networking tools using Javascript and collection of modules which handle various functionalities.

» Node.js modules use API which is designed to reduce the complexity of writing server application.

» Node.js is used to build network programs like Web servers.

» Node.js can collect form data.

» Node.js can add, delete, modify data in your database

» Using Node.js saves the waiting time in between the instructions.

Every technology has its own pros and cons. But, one thing that distinguishes Node.js is that it was developed for applications at scale. Modern tools and exquisite way of handling complex applications makes Node.js stand out.

Scalability:

As Node.js is built upon Google V8 and written in C++, it is used in multiple operating systems and is super fast. V8 and Node are updated frequently with performance optimization, security, and support for modern JavaScript features.

The architecture of Node is single-threaded and event-driven which allows it to handle multiple connections simultaneously and efficiently. Node operates on a single thread making the use of event loops and callbacks for I/O operations, delegating tasks such as database operations as soon as possible. This allows it to handle up to a million concurrent connections.

Node also has the scalability from the get-go with powerful features such as the cluster module enabling load balancing over multiple CPU cores.

Known for offering high performance

As mentioned earlier, Node.js interprets the JavaScript code vis Google’s V8 JavaScript engine. This engine compiles the JavaScript code directly into the machine code. This makes it easier and faster to implement the code in effective manner. The speed of the code execution is enhanced by runtime environment as it supports the non-blocking I/O operations.

npm Enterprise

The Node Package Manager, allows programmers to install, update, and use smaller open-source software packages (modules), which means they don’t have to write common features from scratch and can avoid new layers of complexities.

As big organizations do not want to store their data in cloud, npm Enterprise allows you to run its infrastructure behind company’s firewall. It gives businesses an access to private register with advanced security features which can help them identify the vulnerabilities and change the unsafe code.

Long Term Support

Every major release of Node.js is actively maintained for 18 months from the date it enters LTS. Later, it will transition to maintenance mode lasting another 12 months. During this time there are no new features introduced in the version. But all bug fixes or security updates are done. It is a big step forward for complex enterprise applications.

Apart from these, Node. js is helpful in building cross-functional teams and is highly extensible.

Why Node.js 10 is Going to Rule the Enterprise Application in 2018?

Vishal Virani — Fri, 11 May 2018 12:55:21 +0000

It’s 9 years since Node.js came into existence, and each year it seems to be going strong. Node.js has served to be a strong base for several web applications and solutions.

The Node.js application development is going strong with the 8.8 Node instances online along with a strong Node community, which backs the developers in times of need.

There are a lot of enterprises that are backing their web applications with Node.js. In fact, for most of them, Node.js is their primary production framework. There is a reason why Node.js has become more important than you had imagined.

Why Node.js is important?

Node.js has been specifically designed to develop server-side applications. An open source framework, it uses the JavaScript runtime environment. There is a specific reason why the need for this technology has gone up, and why enterprises are hiring dedicated node.js developers.

Node.js, unlike other frameworks, executes the I/O processes asynchronously. This calls for well-optimized and fast processes in turn. This is one of the reasons why Node.js is popular among web developers. The framework can handle large scale of data, and can read/write the streams to websockets just as well as they would to the HTTP. This means, the read/write along the websockets helps unleash the output in real-time.
With Node.js Paypal was able to double their requests per second, and reduce the overall response time by 35%
js asynchronous I/O allowed Walmart to introduce some interesting features. Even on a busy day like Black Friday, the servers did not go beyond 1% with the CPU usage, and their Node.js based application performed like a pro
Developing applications with Node.js is easy. What you really do is write applications using small modules and then pipe them together. So, when you have to change a particular functionality, you just need to pick the module that owns it and change it. You won’t need to go through the entire code base to make minute changes.
Event-driven architecture is yet another reason why the Node.js is popular with enterprises. The fast execution and high performance of the Node applications is because of the event loop. It is because of the event driven architecture that the I/O operates asynchronously.

What happens in this case?

The asynchronous task is sent through an event loop with a callback function. Once this is done, it begins executing the program. Once the async process is completed, the event loop executes the callback function. Node.js registers with the operating system, and when the connection is made or the callback executed, the operating system will notify the Node application. At the end of all the callbacks, Node.js exits the event loop.

What’s new in the Node.js 10?

Everyone has been talking about the Node v10 since long. Released in April 2018, this is definitely a revolutionizing version, as it has introduced new programming features and functionality.

HTTP/2 stable support: The HTTP/2 was introduced in the Node.js version 8. However, the stable HPPT/2 has been introduced with Node core in the version 10. HTTP/2 allows you to use the existing connection made by the server to send in multiple requests. If you use the HTTP/2 in microservices environment, your application won’t be disturbed by the Node processes.
When you load multiple HTML script files to the browser, they were not considered as modules as they were modules within the global namespace. There was the module pattern workaround but, it was hardly convenient and hassle-free. Node.js has introduced a solution to this problem with the ECMAScript Modules. However, the v10 has not introduced a full implementation of ESMs
Array reduce has grown 10 times faster than what it was when first introduced with the v6.0, specifically for the holey double arrays. With the Node v10, the performance of the async generators as well as the async iteration has improved greatly.
The error handling has improved effectively with the version 10. You need the error codes which reduce the effort gone into checking the errors continuously
Performance of the code is a great concern for the developers. With the version 10, they have greater visibility into the code performance and use trace events to find the performance issues. There is an API within this version which allows the user code to enable and disable the trace event during the runtime. This helps greater depth to diagnose the probable issues in the code.
There is a continued improvement on the security triage in Node v10 for the third party NPM modules
Improvements have been made to the JavaScript language. The prototype.toString() returns an accurate slice of code text along with the mitigations for the side-channel vulnerabilities.

How Enterprises use Node.Js

If you want a Netflix like application for your business, which has a huge amount of content being streamed regularly, you might want to turn to Node.js. The secret of the efficiency of this platform lies in the data handling capability and the massive performance. Enterprises have been using Node.js effectively to perform a number of tasks, and in some cases as their primary network.

Netflix has scaled horizontally with Node.js. Live streaming of data over Windows was something that did not work for the company. When Netflix had just started out, there were close to 50 titles, and they would all be streamed over Windows media player. Since Netflix went on Node, it has become productive and efficient. From data access to client logging, everything seems easy with the framework. They have developed a monolithic JVM system which allows them to mutate and access the data with ease.They have broken down the monolith into manageable, smaller pieces, which can be easily run on local machines
Capital One has invested in Node.js to create an open-source dashboard for their DevOps. They have used the Node.js for front-end as well as back-end of the dashboard. Apart from that, they have used it to define and access the orchestration layer. The front-end and back-end team are integrated as a result of Node.js. Reusability of the modules has heightened with Node.js
Godaddy and Paypal have also effectively used Node.js for their applications

Uses for Enterprises

The enterprises can use Node.js to extend the reach of their product. Integrating new data sources for the same is easy with Node.js as all you have to do is disconnect the front-end and back-end of your application. The new data sources are actually new opportunities for the enterprises.
You can create applications that go beyond the device with Node. For instance, Slack uses Node.js to be available across the devices. The data sync between the devices makes the user know what’s new and what they are supposed to be doing, while on the device of their choice. Node.js allows the application to leverage the OS capabilities
Data-driven applications: Enterprises loaded with data can create data-driven applications at high speed and performance with Node.js. The framework ensures a direct access to the data to its users.
Enterprises can dive into developing single page applications or real-time applications with the node framework.

Moving ahead with Node 10

The underlying capabilities of Node.js V10 will largely enhance application development, make it more flexible, and improve the quality of applications. Enterprises will be able to establish their presence and expand their footprints with the help of this new version and its extensive capabilities.

Node.js with its powerful features, reduced response time, and accelerated performance will help enterprises reach the next-gen position with ease.

What Is Node.JS And Why One Should Hire Node.JS Developer In 2018?

Vishal Virani — Thu, 03 May 2018 11:24:47 +0000

Node.JS is an open source cross-platform to create cost-effective, large-scale applications for your business. Node.JS can be used in building highly scalable, data-intensive, real-time back-end services.

It is being used by some bigger companies like PayPal, LinkedIn, Uber, Netflix, Walmart, Trello, Medium, eBay, NASA, Groupon and so on.

Here are in-depth examples of PayPal & Netflix’s Use of Node.JS

PayPal was the first one to get the opportunity of using Node.JS for their application development. Earlier, PayPal built their application with JAVA on the front-end and JavaScript on the user’s side. After that they started building up the prototyping with JAVA and Node.JS both, just to try and check out how does Node.JS works. And Node.JS could impress PayPal.
On the one hand team of 5-6 employees were assigned to develop a prototype with JAVA and on the other hand team of 2 employees were assigned to the same task using Node.JS. The team developing a prototype using Node.JS could make it almost in the halftime than the time taken by JAVA team. And they found one more thing, applications built with Node.JS works faster than built or developer using JAVA. And as a result, PayPal got doubled the number of request surf per second.
Netflix is another example where Node.JS is being used. In earlier days, Netflix built up its web application using JAVA server side and JavaScript on the front end side, too. So the developer had to have the understanding of both the languages to code it twice. And the other task needed to be done twice. Like, compilation, finding bugs and debugging them. Netflix moved to Node.JS because only one-time coding is needed so every work gets divided into half. No two times compilation or debugging the errors.

The performance offered by Node.JS is better than the JAVA especially in building up and starting up time. Plus, one more benefit is, one can easily build up single page application using Node.JS without any complexity.

Some of the technical objects of Node.JS:

Threading

Node.JS operates in a single thread
Node.JS uses non-blocking I/O calls

V8

Node.JS allows the support of thousands of concurrent connections without getting errors.
V8 is the JavaScript execution engine built for Google Chrome and open-sourced by Google in 2008
Written in C++, V8+ complies, JavaScript source code to native machine code instead of interpreting in real time.

NPM (Node.JS Package Management)

It installs Node.JS programs from the NPM registry
Organizes the installation and management of 3rd party Node.JS programs.
As it’s not same as JavaScript, it install codes and manages code dependencies from the command line.

Unified API

Node.JS can be combined with a browser, a database that supports JSON data and it’s for unified JavaScript development stack.

Event Loop

Node.JS registers itself with the operating system so the OS get notified if it gets issues and calls back.

Development libraries of Node.JS:

Mocha.js: It’s a testing framework and it allows us to test in both console as well as in the browser.
Express.js: It’s basically to develop effective mobile and web applications. It’s the minimal framework for web development using Node.JS and Express.js.
Passport.js: Passport.js is an authentication tool for Node.JS. It provides us a range of 300 different ways for authenticating our website or app.
Socket.io: It is the library that enables cross-browser bi-directional communication between two web servers. It is extremely proficient in developing real-time apps across all web browsers and most mobile devices. It is one of the most rapid and most reliable real-time engines.
Meteor.js: It is the framework that is implemented for rapid prototyping of the JavaScript apps.
Math.js: As from the name itself you can guess, it’s the library which contains mathematical functions provided by JavaScript and Node.JS.
Mongoose: It’s an object data modelling (ODM) library that integrates both MongoDB and Node.JS.
Protactor.js: It’s an end-to-end testing framework. Which is used for functional testing in AngularJS applications.
Async.js: The processing and execution technique of JavaScript is a little complicated, and it follows a certainly predetermined algorithm. The Async.js is a library function that is used to synchronize the data that is being executed.
Moment: It is a JavaScript date library that is used for validating, converting, manipulating and formatting dates. Moment was primarily designed to work in both Node.JS and in the web browser. Hence, the codes and unit tests run must work in both these environments.

Why to use Node.JS for your backend?

Node.JS provides a JavaScript runtime environment built on V8 engine plus it’s a single threaded environment which runs faster.

Node.JS uses an event-driven and non-blocking I/O model which makes it light weight, speedy and efficient performer.

Some cases are like real-time applications (live gaming, voting polls, chat boxes), single page application development, generating live reports for data entry.

Why to use Node.JS for your frontend?

Whether we know it or not, we are using Node.JS in a day to day life regularly. Everyday knowingly or unknowingly we are running it. Like we have automated some tasks for our daily life like, to-do list, reminders or some chat boxes we use.

Tools like Grunt, Gulp, Brower has leveraged the capabilities of Node.JS to improve our software development.

But yes Node.JS was built to use it as a server-side runtime environment so there is not much into front-end development.

How can you hire a Node.JS developer?

If you’re looking for hiring Node.JS developer, Coruscate is the perfect technology partner for your mobile and web application development.

For an example, our client, Loan Studio asked for a mobile application, which includes total 7 types of loan products including home loans, car loans, and machinery loans.

These individual loan requires a different set of documents and follow different processes to get approval.
The to and fro involved in processing a loan is high
When your loan repayment period is over, you need to get NOC from the bank to mark the loan closure.
You are seldom aware of the loan interest rates, the new laws and etc. pertaining to the loans
The users are not very pro about the banks that make loans easy
The client wanted a system that could handle end-to-end loan processing.

So we offered them an application based on Node.JS as a solution to help processing in an easier way.

Pre-defined checklist for the individual loan
The user can upload the required documents.
Validation of the documents
CIBIL score and bases on loan type suggestion on where to apply

During the development phase, we got one error like, already the application is being developed in a static manner and later on they asked for a dynamic one. So with Node.JS changing the codes and the needed stuff was easier and not tedious job.

Our clients ask for PHP or JAVA based developed application but then by advising them based on our previous delivered solution and the benefits of Node.JS along with the features, they make up their mind to get it done in Node.JS.

Our technical team are always happy to look into your requirement and figure out the right solution for the same. Let’s get connected!
