Node JS

JavaScript’s rising popularity has brought with it a lot of changes, and the face of web development today is dramatically different. The things that we can do on the web nowadays with JavaScript running on the server, as well as in the browser, were hard to imagine just several years ago, or were encapsulated within sandboxed environments like Flash or Java Applets.

NodeJS is a javascript runtime built in Chrome’s V8 engine. Node allows you to execute Javascript code outside of the browser, in a computing environment (such as a server or local development environment) rather then a browser environment.

The Benefits of Node js

The Fast Suite

Companies are in awe of the speed at which Node.js functions. It runs on the V8 engine developed by Google that uses JavaScript into native machine code and operates at a super speed. Node.js spares all the trouble involved with forming separate threads and instead uses a single thread, that is, the event loop that takes care of all the asynchronous I/O operations. Major actions in web applications including reading or writing to the database, network connections or file system can be performed quickly with this suite.

Node.js empowers the organizations to create quick, robust network applications that can tackle parallel connections with increased throughput. It does not slow the working by any chance, but the developers need to be careful while writing the codes and the applications will get onto the right track.

Go with Data Streaming

Generally, in web platforms, HTTP request and response are considered two separate events but actually they are data streams. This feature can be utilized to its fullest with Node.js to create some of the best attributes like processing files at the time of uploading time as this can reduce the overall processing duration when data comes in the form of streams. The same can also be deployed at the time of real-time video or audio recording

Present Everywhere

JavaScript is present now in the browser as well as the server just because of Node.js. Be it the browser or server, Node.js code runs in a similar manner and is flexible in usage. If an enterprise questions the logic for the browser to be shifted on to the server, it can consider Node.js code migration.

Real-Time Web Applications

Worried about low-level sockets and protocols? Let that be a thing of the past as Node.js is here to build real-time web applications at a lighting speed just in the same time required to make a simple blog in PHP. The suite is a clear winner in multi-user real-time web apps as in games and chat apps.

The event-driven architecture caters to both the client-side and the server-side that are written in JavaScript and thus the synchronization process is fast and orderly. The event loop through web socket protocol which works on TCP handles the multi-user function and prevents the overhead of HTTP for web development.

Solves All Database Queries

The database queries for new NoSQL databases like MongoDB, Couch DB have the JavaScript framework. Developers need not modulate the syntax differences while uniting the Node.js and NoSQL databases. Node.js access with real-time web apps as the JSON stored data format enables it to run without any obstacles in data conversion and mismatches, not like Ruby on Rails platform that needs the same format from JSON to binary models.

 Dynamic NPM

As Node.js is an open-source technology, it gives an edge with a shared repository of dynamic tools and modules. The amount of modules that are more than 60000 in the Node Package Manager (NPM) has risen with a significant growth and is on the point of beating the RoR (Ruby on Rails) platform. Given that NPM is robust and super speedy it aids in making the dependency management perfect. With the wide popularity of Node.js, the node community is getting stronger day by day.

 The Hosting Deal

As more and more developers are shifting towards Node.js, hosting is also gaining momentum. PaaS (Platform as a Service) service providers such as Heroku and Modulus are officially allowing node deployments without any problem.

 Good with Sync Issues

Node.js is very efficient in managing asynchronous I/O from the root and is competent enough to solve the common web and network development problems. Besides the speedy JavaScript performance, the heart of Node.js is the Event Loop. To handle numerous clients, all I/O rigorous tasks in Node.js are undertaken together.

 Community Friendly

Besides its core competencies, Node.js consists of a flourishing open source community that has delivered many outstanding modules, making the Node.js applications shine all the more. A popular one is Socket.io, a module to handle constant communication between the client and the server allowing the server to push real-time updates to clients. It operates on the best technology used to form these links away from the developer, particularly for specific clients.

In short:

Node.js shines in real-time web applications employing push technology over web sockets. What is so revolutionary about that? Well, after over 20 years of stateless-web based on the stateless request-response paradigm, we finally have web applications with real-time, two-way connections, where both the client and server can initiate communication, allowing them to exchange data freely. This is in stark contrast to the typical web response paradigm, where the client always initiates communication. Additionally, it’s all based on the open web stack (HTML, CSS and JS) running over the standard port 80.
