Hire a Node.js developer in India and save 70% cost

Node.js is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code outside of a browser. If you are looking to hire a full time Node.js developer the best place is India, as you can save 70% cost.

Node.js is a framework that has reached the version 5.5.0 after a troubled fork path and rejoining of the code and the group of Node.JS developers which allows you to write applications in server-side JavaScript.

The code is executed through V8, a JavaScript engine developed by Google that boasts excellent performance both in the browser and standalone. Starting from 2009, the year of the project’s birth, Node.js has experienced an extraordinary and ever-growing interest and many highly prestigious companies are using it intensively for various web based services.

But what are the reasons for this success? Node.js is a server-side technology with an event-driven asynchronous I/O model, a model that is particularly suitable for programming in JavaScript and for web applications.

The normal procedure of running a server-side application, written for example in PHP, involves the flow of a series of instructions that frequently involve calls to external services such as queries for a database, or access to the filesystem for operations reading and writing. All these events are blockers, meaning that the execution of the script is stopped until it receives a response from the external component to which it has requested it.
In this way, the web server takes most of its time waiting for the blocked processes to complete and this leads to a conspicuous inefficiency in the exploitation of available resources.

Contrary to what happens with PHP, the technique already widely used in JavaScript programming of asynchronicity allows an optimization of time and resources much more satisfying because the path that leads to the result does not encounter blocks and dead times.

As we can see from the output, the JavaScript engine did not stop waiting for the completion of the first routine, but continued with the next instruction. Once the wait is over (in the cases we are interested in, this could be the opening of a file or the execution of a complex query) the callback function is executed.

In other words, the code tells Node.js what to do when the pending event is completed, but at the same time it can start new processes and complete them without having to wait for the completion of the still incomplete processes.

This technique applied to the server side can therefore have enormous advantages, but at the same time requires special attention to concatenate two or more operations that depend on each other, such as a write operation on a file that must first be created or read via the filesystem. We will return to the most suitable techniques to manage this particular programming style in a specific chapter of the guide.

Installing Node.js

On the Linux platform the installation can be completed by compiling the source that is always available from the download page, or, more simply, through the package manager available to the distribution on which we are working. In this page lists commands for the major distributions supported.

Node.js seems to be the system that responds better than others to all these requirements. Its speed, scalability and efficiency make it ideal for the development of data intensive applications in real time. Moreover, for Node.js “real-time” is a cornerstone of its development.

This platform has grown a lot in recent years, and has ample support from thousands of Node.js developers around the world, who have contributed more than 650,000 modules (to this date: May 3, 2018), collected within the Node Packaged Modules (NPM). Within this sea of code there are modules built to work with Arduino, BeagleBone, Intel Galileo, Raspeberry PI, BlueTooth, energy control, robotics and so on. Say what you need, NPM will (almost) always be able to provide what you need!

Other projects related to Node.js

Node.js is not only used for server-side technology in the strict sense: various web-developer software such as LinkedIn, PayPal, Uber and Netflix are distributed with the Node package manager, npm and rely on its infrastructure to make these open source tools available on all platforms where you can install it.

Node.js develop API is simple. In fact, it has at least three frameworks expressly dedicated to the development of APIs such as Express (my personal choice), Restify and Hapi. All these points clarify how Node.js is one of the best choices if your intent is to:

– divide the logic of your products into small pieces to share it among the different devices;
– think in terms of scalability through API development;
– focus on a clean and extensible design;
Finally, the NW.js project combines Node with Webkit to create desktop applications for different platforms (Mac OS X, Windows and Linux) from a single source developed with web-based technologies.
