#node.js vs php

In this article, we will share information about which is the best Node.js vs PHP, and also share advantages and disadvantages to decide the right environment for your project.

Do you know what Walmart, Netflix, Mozilla, GoDaddy, and Microsoft have in common? Think, Think, Think!

Fail to connect the common ground among these giants? Well, let us clear the confusion – All these tech giants are using Nodejs development to offer the real-time experience to their users. Today, many web development companies have moved to a uniform web language with Node.js that leading the way.

Before we discuss why top companies are choosing Nodejs, let’s understand what is Nodejs!

A Brief About Nodejs:

Node.js is a cross-platform & open-source JavaScript run-time environment that executes JavaScript code outside of a browser. Also, it allows the Node js developers to create web servers & networking tools using JavaScript and a collection of modules that handle various core functionalities.

Nodejs was originally written by Ryan Dahl, 13 years after the introduction of the first server-side JavaScript environment “Netscape’s LiveWire Pro Web.”

This programming language came into the existence with the idea of extending the use of JavaScript in the web browser. Unlike PHP & Ruby on Rails, Node.js has a non-blocking event-driven I/O model, which makes it an excellent choice to build robust & scalable applications. Read our other blog to check the comparison of Nodejs vs PHP.

How Did it all Start? The Origin of Nodejs:

Dahl created this language because he wasn’t happy the way Apache Http server handles multiple concurrent connections. In fact, he criticized the way code was blocking the entire process or implying multiple execution stacks for simultaneous connections.

His urge compelled him to create a Node.js project that he demonstrated at the inaugural European JSConf on 8th November 2009. The smart utilization of Google’s V8 JavaScript engine, event loop and low-level I/O API in the project managed to win millions of hearts.

In June 2011, Microsoft and Joyent together implemented a native Windows version of Node.js. The first version was released in July 2011.

In January 2012, Dahl stepped aside & promoted the co-worker and npm creator “Isaac Schlueter” to manage the project.  

How Does it Work?

JavaScript and Node.js run on V8 JavaScript runtime engine. This V8 engine converts the JavaScript code into faster machine code.

Nodejs Architecture Includes:

Single Threaded: Node.js works on a single thread. This approach is worth considering as it avoids context switching.

Event Loop: The event loop allows node.js to perform non-blocking I/O operations despite the single-threaded feature. A transaction passing through Node traverses a cascade of callbacks. And using the ‘libuv’ library, it handles queuing & process the asynchronous events.

Non-Blocking I/O: This loop works on a single thread, but the runtime tasks are executed asynchronously on worker’s thread top that returns the result via call back to the event loop thread. This is a great non-blocking way of handling code execution.

Front-End Development: The front end is what is visible to the user, and he engages and performs activities. Front- End Development covers coding the UI interface, handling events, and thereby interacting with back-end server to pull data at the front-end UI side.

Back-End Development: The back-end is the technical work that is not visible to the user. It deals with server-side scripting and database interaction so that the data can be requested by front-end apps.  

Nodejs Features:

Encourages Sharing: Robust Node Package Manager (NPM), encourages sharing. Having a repository of 50,000 packages, developers manage to build effective solutions. With inbuilt NPM, it becomes easy for developers to update, share or reuse codes.

Lightweight and Scalable: Nodejs development accelerates with the V8 JavaScript engine without compromising on quality or security terms. Additionally, the non-blockage of the thread makes the application lightweight, scalable behaving in a network-friendly manner.

Ideal for Real-Time Applications: The language has extraordinary features for creating real-time applications like chats and gaming apps. It is also an ideal fit for programs that require an event-based server or non-blocking server.

Data Streaming: HTTP requests responses are considered as isolated events, but in reality, they are streaming data. You can leverage data streaming in Nodejs by incorporating features like processing files when uploaded. It drastically decreases the complete processing time.

High-Performance: The single threaded JavaScript runtime offers seamless network applications. Built upon Google Chrome’s V8 runtime and coded in C++, Nodejs is specifically built for multiple operating systems. Both V8 and Node are updated on regular intervals with performance optimization & security patches while supporting JavaScript features.

Suitable for Microservices: All big names are utilizing Node.js for its microservices. Wondering why? Well, Node.js has the ability to optimize the performance of your application. Furthermore,  eliminating the unwieldy modules make it simpler to operate microservices on Node.js applications.Cross-Platform Development: Nodejs collaboration with Electron or NW.js allows you to build cross-platform applications. 

Powerful Single Codebase: Nodejs has proved itself as a game-changing technology as it allows Node.js developers to code JavaScript server side and client side. This makes it easy to send & synchronize data between the points automatically, saving a lot of development time.

Wait, there is more to add!Node.js embraces flexibility with features like cluster module enabling load balancing over various CPU cores. Besides, the use of robust tools like PM2 process manager makes it simpler to monitor, optimize and deploy Node applications. 

Getting Better Each Passing DayNode.js is improving for the better each passing day. It keeps launching new releases while enhancing the standard of the codes/features. Moreover, with the support of an open source community, this technology will be nourishing in the near future.
