Understanding NodeJS for Web Development

NodeJS for Web Development

NodeJS is a server-side JavaScript developed for high performance during the framework of network application and optimized for concurrent environments. It is a command-line tool and written with JavaScript and C++. 

It runs outside a browser with the help of backend JavaScript code, utilizes Google’s V8 Engine, and possesses Node Package Manager (NPM) Library with a varied runtime environment.

Features of NodeJS

It is estimated that roughly 43% of users of NodeJS are interested in enterprise applications and rest for web app development. This open-source Javascript program that executes outside the browser. NodeJS has the following important features:

●  NodeJS utilizes a non-blocking I/O model that is lightweight and event-driven.

●  NodeJS is written by the collaboration of JavaScript and C++ programming.

● The callback functionality of JavaScript utilizes event-loops for the implementation of the non-blocking I/O model.

● The programming inside NodeJS runs in a single thread and DOM implementation of JavaScript.

●  Real-time web applications with two-way connections are a recent addition in NodeJS.

Rise of NodeJS

NodeJS has boosted business productivity to a large extent, and among the users, only 4% felt no impact of NodeJS over their business. NodeJs is the topmost used platform as reported by the statistical data being collected in 2019. 

NodeJS is most popular among all the worldwide developers involved in libraries, frameworks, and tools. Additionally, the popularity increased with the job trends as NodeJS implemented a relative growth in skills for employment. The growth rate of NodeJS is the fastest among all the allied technologies.

Application of NodeJS

Almost all the users associate words such as simple, easy, powerful, and flexible with NodeJS usability and functionality. In the recent modification, NodeJS has updated some mind-boggling improvements such as reducing the loading time to 50-60% and reducing the developing costs by 58%. There are many things to do with NodeJS, such as:

● NodeJS can help in creating an HTTP server with only four lines of JavaScript programming. 

● A similar TCP server can also be created with the same four lines of JavaScript.

● NodeJS can successfully create a DNS server and static file server.

mobile app for your business or any application that involve real-time data are created with NodeJS.

● NodeJS depends upon modules and NPM can be bundled with the installation.

Benefits of NodeJS

NodeJS is appropriate for the creation of a website application that includes real-time services, chatbots, messengers, and other lively features. 

The users should not worry about the CPU-cycles and the requirement of a high-concurrency level is satisfied by NodeJS. After a consequent usage of NodeJS for two years, most of the companies have reduced their development costs to 12%. The core benefits of NodeJS are:

Performance and Growth

NodeJS is well-known for its express speed, and high-traffic sites benefit the most from this. The code of written language is C++ and it is operational in all the commonly used operating systems. 

It is built over the V8 runtime of Google Chrome, making it extremely convenient and fast-paced because of its functionality over single-thread, NodeJS can manage thousands of connections that support the scalability of all the advanced features for future growth.

Multifunctional Operations

NodeJS is the most powerful example of utilizing the cross-functionality of different experts. It is based on JavaScript and knowledge of one single language can help in building the codes from client-side and server-side. 

All the developers associated with an organization can work as a full-stack developer without undergoing any other additional courses. The entire web application can be successfully built with the help of developers who have knowledge in javaScript.

Enterprise version of NPM

The NodeJS package installer has advanced its features and developed into a more premium and useful enterprise version. 

Developers do not need to worry about starting from scratch as NPM can assist them in installing packages and resources in the form of modules. It will help the big enterprises to store a large amount of data on the cloud, with the private registry and high-grade security systems.

Service and Support

It is found in research that more than 85 countries worldwide with more than 45 different native language users utilize NodeJS.NodeJS has very high technical support. They promise to provide long-term support (LTS) for technological diversifications. 

The developers of NodeJS will have the liberty to maintain an application written in an outdated language. It is one of the first choices for the majority of application developers. In 2018, there were almost 23 million NodeJS developers in the world and soon it is roughly estimated to reach 28 million at the end of three years.

NodeJS is among the top choices for startups. The reason is NodeJS can be utilized in CPU cycles, chat or messengers, I/O operations, real-time and high concurrency applications. However, NodeJS is unsuitable for heavy computations and complicated web applications.
