Node.js for your backend in 2023: Comparisons and reasons

What is Node.js?

‍

Node.js is a software development technology used by some of the most prominent companies worldwide to build fast, high-quality applications, from Netflix and PayPal to LinkedIn.

‍

Developed by Ryan Dahl in 2009, it's an open-source JavaScript runtime environment and library for running web applications. Its latest version was released in April 2021. 

‍

Development teams use Node.js to create server-side, cross-platform web applications, as it is ideal for data-intensive solutions thanks to its asynchronous, event-driven model.

‍

It is used primarily for non-blocking, event-driven servers, such as traditional websites and backend API services.

‍

However, it was initially designed with real-time, push-based architectures in mind. Every browser has its version of a JavaScript engine, and node.js is constructed on Google Chrome's V8 JavaScript engine.

‍

With Node.js, entire websites can run on a unified stack, which allows for quick and easy development and maintenance, enabling teams to focus on meeting the project's business goals.

‍

Node.js is open source which means it is free to use and constantly improved by a global community. Node.js is neither a framework nor a library but a runtime environment.

‍

A runtime environment contains lightweight, flexible, and easy-to-deploy Web APIs that developers can access to build code, along with a JavaScript engine that parses that code, which helps to optimize and speed up your application project.

‍

Whereas most runtime environments rely on multi-threaded processing models, Node.js employs a single-thread design. 

‍

In multiple-thread processing, a thread is utilized every time a request is received until all threads are used.

‍

When this occurs, the server has to wait for an active thread to become free again. Restricted threads can make for slow and inefficient applications.

‍

Node.js, however, uses single-threaded processing. A single-thread architecture can perform and scale much more quickly and efficiently than multiple-thread setups. 

‍

Why use Node.js for your Backend?

‍

There are many reasons developers prefer using NodeJs for the server side of their applications. NodeJs execution time is swift, and it runs very quickly. With more than 50,000 bundles available in the Node Package Manager, developers can import any packages at any time according to their needed functionality, saving a lot of time.

‍

As NodeJs does not need to wait for an API to return data, it is beneficial for building real-time and data-intensive web applications. It is asynchronous, which means it is non-blocking. 

‍

Loading times for audio and video are reduced in Node.js thanks to its optimal code synchronization between the client and server for having the same code base.

‍

As NodeJs is open-source and is a JavaScript framework, it is straightforward for developers who are already used to JavaScript to start developing their projects with NodeJs.

‍

Asynchronous in Nature and Event-driven‍

‍

The servers made with the NodeJs never wait; they directly move to the following API. So all the APIs of NodeJS are non-blocking in nature.

‍

It follows an event-driven mechanism to receive and trace all responses from previous API requests. Hence, all the NodeJs APIs are non-blocking in nature.

‍

Single Threaded Architecture

‍

‍With event looping, a single-threaded architecture is followed by NodeJs, and this architecture makes NodeJs more scalable. In contrast to other servers, they create limited threads for processing requests.

‍

Whereas for the event-driven mechanism, the NodeJS servers reply in a non-blocking or asynchronous manner; for this reason, NodeJS becomes more scalable compared to other traditional servers like Apache HTTP servers.

‍

NodeJs handles a more significant number of requests, as a single-threaded program is followed by NodeJS, which allows NodeJs to process massive requests.

‍

Scalable‍

‍

One of the most pressing concerns in Software Development is addressed by NodeJs: scalability. NodeJs uses a clustering module for managing load balancing for all active CPU cores.

‍

One of the critical features of NodeJs is its ability to partition applications horizontally, a procedure mainly achieved by using child processes.

‍

Partitioning ensures that distinct app versions are provided to the different target audiences, and customization allows them to cater to the client's preferences.

‍

Compatibility on cross platforms

‍

‍Different desktop systems and mobile devices can use NodeJs. For generating a self-sufficient execution, developers can pair it with any appropriate package. 

‍

Uses JavaScript‍

‍

From a developer's perspective, it is an essential aspect of NodeJs that it uses JavaScript; since most developers are familiar with it, it becomes significantly easier to migrate to NodeJs.

‍

Fast Data Streaming

‍

‍The processing time of data transmitted to different streams requires a long time. However, for processing data, NodeJs takes a concise amount of time and does it at a high-speed rate. NodeJs is very efficient thanks to files being processed and uploaded simultaneously. 

‍

Node.js vs. Ruby on Rails

‍

Ruby on Rails (RoR) is another popular server-side web application development solution. Even though both runtime environments can manage apps of any complexity, they are designed and constructed based on different visions and architectures.

‍

Node.js is more appropriate for dynamic applications with numerous server requests and constant data shuffling between client and server.

‍

Some examples of these are instant messaging apps, chats, and collaborative apps commonly referred to as RTAs (Real-Time Applications).

‍

Event-based Node.js architecture handles heavy I/O operations, server requests, and data flow, which makes it the preferred solution for Single Page Applications (SPAs) that require intensive client-side processing and rendering.

‍

On the other hand, Ruby on Rails performs better than Node.js in CPU-intensive applications. Node.js is a single-threaded environment not designed for CPU-intensive applications that deal with graphics, images, and data.

‍

Computations on vast arrays of data may block all incoming requests, making the primary advantage of Node.js useless.

‍

Rails is definitely a better option if you want to build a CPU-heavy application. Rails is also ideal for speed-critical projects, with several modules and generators ready to use.

‍

While Node.js repositories provide generator scripts to make development more agile, fast prototyping is the essence of Ruby on Rails.

‍

Node.js vs. Python

‍

Python is a high-level, interpreted, object-oriented programming language focusing on readability and productivity; it supports multiple programming paradigms, making it an excellent choice for various business tasks.

‍

As such, it provides ease of use and rapid development with a rich standard library and ecosystem.

‍

Python is ideal for CPU-intensive applications, which we've already established aren't Node.js's strong suit. Python also holds the edge on time-critical development and deployment options.

‍

With its rich standard library and modules available out of the box, you don't need to search for many utility modules and packages for your application.

‍

Instead, you can immediately design a fully functional prototype, which the development team could supplement with other features later. Python's simple and concise syntax makes writing code very fast too.

‍

However, when the performance and scalability of web applications are of concern, Node.js outperforms Python; it's lightweight and fast.

‍

In addition, Node's power in handling heavy I/O operations and shuffling of data between the front and back end makes it the better choice for Single Page Applications and Real-Time Applications.

‍
