Node JS Advantages for Web Projects & Businesses (2024)

After almost 20 years of web-based on the stateless request-response paradigm, web applications with real-time, two-way connections are finally here. Node.js has become increasingly popular in the creation of apps over the past four years. The popular programming forum Stack Overflow has even acknowledged it as the best framework in the world.

Node.js is popular because it is a server-side proxy that can handle many concurrent connection requests. It’s handy for proxying many benefits with varying reaction times or obtaining data from multiple sources and locations.

Let’s find out more about when to use Node.js and why.

What Is Node.js?

Node.js (or simply Node) is a server-side platform for handling JavaScript through the V8 engine. JavaScript acts on the client side, while Node acts on the server. Node can work with external libraries, call commands from JavaScript code, and act as a web server. With Node, you can write full-fledged applications.

Until 2009, developers used the JavaScript programming language only in browsers. After the creation of Node.js, it became possible to write code without the involvement of Internet search software. Programmers use the tool to create programs directly from the command line.

Like JavaScript, Node runs in V8. It is a runtime environment that translates what the web developer has written into machine code – a set of direct instructions for the computer that do not require interpretation. This fact makes the low-level code fast and easy for the machine to recognize.

To understand why to use Node.js, look at its functions.

Features of Node.js

Below are the essential features that make Node.js stand out from other server environments.

• Super Speedy

The Node.js framework boasts rapid code execution because of its foundation on the V8 JavaScript Engine in Google Chrome.

• Asynchronous, Event-Driven

All Node.js library APIs are asynchronous or non-blocking. It implies that a Node.js server never waits for an API to return data. After calling an API, the server proceeds to the following API, and a Node.js Events notification mechanism helps the server receive a response from the previous API call.

• Buffering-Free

A Node.js application does not buffer any data at any time. These apps merely output the data in discrete portions.

• Single Threaded Yet Highly Scalable

Node.js employs a single-threaded event-looping paradigm. The event method enables the server to respond in a non-blocking manner and makes the server extremely scalable. Unlike typical servers like Apache HTTP Server, Node.js employs a single-threaded program that can handle a far higher volume of requests.

• Licensed

The best proof of Node.js security is the MIT license.

How Does Node.js Work?

Node.js core concept is to employ non-blocking, event-driven I/O to stay lightweight and efficient in the face of data-intensive, real-time applications running on multiple distributed devices.

It means that Node.js is not a revolutionary new technology that will take over the web development industry. Instead, it’s a platform that meets a certain requirement. Developers should not use Node.js for CPU-intensive tasks; utilizing it for such tasks will negate nearly all of Node.js benefits. Node.js excels in creating quick, scalable network apps because it can handle a large number of connections at once with high throughput, which results in excellent scalability.

The installed software includes two programs that work together to create powerful functionality.

• Node. This command line is responsible for executing software written in JavaScript. It employs machine code to create numerous tools.
• npm. This is a package management system that employs the installation of numerous network-obtained utilities. It broadens the possibilities and enables the construction of apps using a constructor.

Developer community uses the npm system to increase Node.js’s popularity. Every coder has access to the protocols’ extensive library of modules. You can download some files for free. Another source code requires payment.

Running on a system with 8 GB of RAM puts us at a theoretical maximum of 4000 concurrent connections (calculations taken from Michael Abernethy’s article “Just What is Node.js?,” published on IBM developerWorks in 2011, plus the cost of context-switching between threads. In conventional web-serving systems, this is the typical situation.

In general, developers must prevent an exception from reaching the top-level (central) Node.js event loop, causing the Node.js instance to crash (effectively crashing the program).

npm: The Node Package Manager

Those who work with software development should keep in mind the following npm modules:

• Express. Express.js is the de facto standard for most Node.js apps nowadays and a Sinatra-inspired web development framework for Node.js.
• Hapi. Hapi is a highly flexible, user-friendly, and lightweight configuration-centric framework for creating websites and service-based software.
• MongoDB and Mongols. These wrappers for the MongoDB database provide an application programming interface (API) for MongoDB object databases in Node.js.
• Forever. This is the most common way to run a Node script repeatedly. It keeps your Node.js process running in production even if something goes wrong.
• Socket.io and sockjs. These are two of the most common websockets components used on the server side.
• moment. A lightweight library for parsing, validating, manipulating, and formatting dates in JavaScript.
• connect. Connect is an extensible HTTP server framework for Node.js that provides a set of high-performance plugins referred to as middleware; it serves as the foundation for Express.
• pug. One of the most widely used templating engines, pug (previously Jade), was modeled after HAML. Developers use it by default in Express.js.
• bluebird. It implements Promises/A+ with all available features that boast outstanding performance.

Who Uses Node.js? Examples of Node.js Use Cases

This development environment allows you to write software for multiple platforms, including the web, OS X, and Windows. It provides developers with new methods for maintaining synchronization between your mobile device and computer, such that text inputted on your mobile device will be reflected on your web browser and desktop/laptop computer. Also, developers can build API with the help of libraries.

In contrast to JavaScript, Node can work with Windows program global objects like the document and window. The door to the user’s computer and file system is now wide open. Furthermore, developers can use any pre-installed apps or libraries. In particular, Nodejs use is most often the following:

Still, some of the popular users of Node.js are involved in different fields. Here are the industry giants who benefit from this technology the most.

Walmart. The largest retail chain in the world has begun selling things over the internet. To accomplish this task, the company developed an asynchronous input/output program, which helped supermarkets save significant resources.

eBay. The 170 million users appreciate the clear, elegant, and well-organized eBay app. The creators sought to create a web platform that was as responsive as possible – interactive and able to interact with visitors in real-time. Not only did they accomplish this goal, but they also set up interaction services, the information from which is updated nonstop on the website’s pages.

Mozilla. Browser developers believe Node has substantially simplified things, pointing to at least two reasons. The first one is that both the front and back end are written in the same language. The second one is the quantity of RAM required for the system to function.

Shutterstock. A site replete with interactions between merchants and purchasers. It permits the presentation of your artwork, music, vector images, and movies. Conversely, a finished object can be purchased for a few cents with standard access and tens/hundreds of dollars with extended access.

Paypal. A system from Elon Musk, Max Levchin, Peter Thiel, Yu Pan, Ken Howery, and Luke Nosek allows users to work with payments without sharing financial information. As of 2018, there were 227 million active accounts on the website. It took half as long to create the app.

Reasons Developers Choose Node.js

There are several benefits to using Node.js, but the non-blocking I/O approach is the most important. The events in this system trigger asynchronous, priority-based processing. There is no need to generate a new thread for each connection, making it easier to manage the load even when thousands of users are accessing the server simultaneously.

Learning this add-on will be far less of a steep learning curve for a developer already fluent in JavaScript than switching to an entirely new technology. Yes, they will have to learn new tools, but there will be many familiar ones, providing relative simplicity and accessibility.

With thousands of programmers working on it, Node.js technology is rapidly progressing. The Node Foundation is responsible for overseeing this procedure. Companies like Google, eBay/PayPal, Netflix, Microsoft, Uber, Linkedin, Yahoo, Walmart, and others have adopted Node.js due to its widespread use and numerous benefits. The importance of a strong community cannot be overstated, as it provides access to support in times of need, a wealth of learning resources, rapid identification of system flaws, a forum for open dialogue, and the possibility of forming new teams.

Easy to Learn & Quick to Adapt

First of all, Node.js is easy to learn, especially if you have experience with JS. If you know the syntax, all you’ll need to learn are the APIs it uses. Moreover, Node.js is an open-source framework supported and improved by a large community of developers. Which means, you can get support from experienced developers worldwide to solve any problem you might have while learning or using it.

High Node.js Performance for Real-Time Apps

Node.js is ideal for building applications for interactive commercial websites, streaming services, social networking, messengers, collaboration tools, etc. These applications have one thing in common – they can transmit live text, audio, or video data in groups or face-to-face interactions.

Easy Scalability for Modern Applications

Another benefit of using Node.js is that it makes it simple for developers to scale their applications horizontally and vertically by adding more nodes. It is possible to run multiple nodes simultaneously, and the environment will automatically distribute the burden evenly among them.

Optimal Solution for Microservices Architecture

The so-called microservices architecture has found its perfect match in Node.js, a simple and lightweight programming environment. With this method, a single program is built up from a collection of independent services that communicate with one another using simple protocols and APIs, most frequently those for managing HTTP resources.

According to the Node.js User Survey Report 2017, Node.js is the preferred technology when creating solutions based on microservices. About half of the respondents use technologies related to microservices (to be more precise, we are talking about Docker – the leading platform for software containerization).

As an example of implementation, consider Walmart’s move to a microservice architecture based on Node.js. This solution allowed the company to gain a lot of benefits:

GoDaddy is another case in which Node.js shows its superiority over its rivals. Super Bowl advertising allowed the company to process 10,000 requests per second without experiencing downtime, despite only using 10% of the hardware’s total capacity.

Excellent for Building IoT Solutions

The Internet of Things (IoT) is an ecosystem of various automated computer devices and digital machines that can exchange data with each other without human intervention. Experts use the technology in various applications and industries. Some examples of the Internet of Things include:

• Agricultural automation
• Smart homes and cities
• Retail analytics and logistics
• Health care for self-monitoring
• Connected (smart) cars

Creating an ecosystem of connected devices using Node.js is a smart choice.

Powerful Community Support to Simplify Development

You must select a technology with a robust community for your Node.js project. The JavaScript and Node.js communities are the most prominent and active of all contemporary software technologies.

Stack Overflow, a community where developers discuss their preferred technologies, education, experience, and career preferences, conducts an annual survey of its participants. This year, over 100,000 individuals participated in the study. For the sixth year, they declared JavaScript the most popular programming language. At the same time, Node.js is the most popular technology in the category “Frameworks, Libraries, and Tools.” Nearly half of the 51,620 respondents reported using Node.js.

Large tech firms like Facebook, Google, Netflix, and Amazon substantially invested in the Node.js ecosystem. They contributed significantly by sharing their knowledge of serverless, creating microservices architecture, and disseminating various open-source, ready-to-use solutions. The fact this technology is backed by industry heavyweights and the largest developer community ensures it will be employed soon and continue to advance, become more effective, and expand its range of applications.

Complete JSON Compatibility

Unlike other server-side technologies like PHP and Ruby on Rails, Node.js doesn’t require a translation between binary models in JavaScript to use JSON for communication. When developing a RESTful API to support a NoSQL database, which is extremely helpful. Another perk of the JavaScript environment is its seamless integration with one of the most popular data transfer standards.

Valuable Help with Building Cross-Functional Solutions

Node.js is also an excellent option for developing cross-platform, real-time online apps, drastically reducing development costs and time. There is no need to design the Node.js application independently for Windows, Linux, and macOS or to recruit distinct developers for each platform. In addition, Node.js developers familiar with Angular, React.js, or Vue can also design both front-end and back-end application interfaces.

Rich Ecosystem

npm also serves as the primary platform for the open-source JavaScript tools that play an essential role in developing this programming language. With about a million libraries currently available in the npm registry and more than 10,000 new ones published weekly, the Node.js ecosystem is quite rich. According to statistics, 97% of today’s web applications consist of npm modules.

Node.js has tremendous potential due to the availability of many free tools with a few clicks. Open-source software is gaining popularity because it enables the creation of new solutions, which reduces overall development costs and time to market (TTM).

Improved App Response Time & Boosted Performance

Node.js is fast. The results of performance tests presented by toptal.com demonstrate this. The researchers compared how popular programming languages handle concurrent requests, including GO, PHP, Java, and Node.js. As a result of its V8 engine, the latter achieves the best results in nearly all metrics. It was initially created for the Chrome web browser. Chrome V8, written in C++, is utilized to compile JS functions into machine code at an impressive rate. V8’s performance has improved over the years due to Google’s substantial investment in its engine, and Node.js has made the most of it.

A further significant benefit is the asynchronous handling of requests. Synchronous processing on the server side indicates that the code is executed sequentially. Consequently, each new request blocks the flow of the others, and subsequent commands will not begin to perform until the previous command has been completed. In turn, the Node.js asynchronous method maximizes the use of single-threaded processing, which reduces response time by a factor of several.

By using a single language on both the client and back-end, synchronization is as fast as possible, and beneficial for real-time, event-driven applications. Because of its asynchronous, single-threaded nature, Node.js is ideal for online games, chat, video conferencing, or any other project that requires constant data updates.

Many leading companies have seen significant improvements since migrating to Node.js – PayPal, for example, reported a 35% reduction in response time after migrating from Java.

Shorter Time-to-Market (TTM)

Node.js utilizes the non-blocking I/O model, which makes it extremely lightweight and efficient. Numerous npm libraries facilitate the development of applications with significantly less effort. Node.js also includes a variety of reusable templates that can reduce the application’s size and the number of issues. With Node.js, the only language utilized on both the front and back end is Javascript. All these factors lead to decreased time-to-market.

Quicker Loading Time

The caching module in Node.js makes it simple for programmers to lessen the time and effort spent on tasks and code re-execution. Your web app’s initial module will be cached in memory at the occurrence of each request. The time it takes for your users to access the web pages will be reduced to a few microseconds.

Good for Building Cross-Platform Applications

With Node.js, you can construct cross-platform, real-time online apps utilizing Electron and NW.js, meaning you no longer need to spend time building separate code for Windows, Linux, and macOS desktop versions.

Your development team may create native desktop applications in the future without requiring expert-level knowledge of Objective-C, C#, or any other language. In addition, your Node.js engineers have unrestricted access to additional Google Chrome Developer Tools for building, debugging, and writing code.

Our staff is willing to answer any questions and provide additional details.

Node.js has fewer drawbacks than advantages, but they are still essential to consider to understand whether the framework suits your project.

Ineffective Management of Excessive CPU Use

Because Node.js first stringifies objects to JSON and then sends them to the client, enormous payloads from Node.js services can also be a problem. This is because Node.js transmits objects to the client after stringifying them. These processes can potentially increase CPU usage, so it’s important to keep the payload size manageable, provide pagination, and avoid populating useless data in advance.

Immature Tooling & Dependency Management

Although the core Node.js modules are relatively stable and mature, several tools in the npm registry are either of low quality or poorly documented/tested. In addition, the registry itself is not sufficiently organized to provide tools depending on their ranking or quality.

No Strong Library Support System

Using Node.js for straightforward programming jobs like image processing, database operations, XML analysis, and other similar activities is challenging due to the absence of a well-equipped and robust library system.

Asynchronous Programming Model

Because of its asynchronous nature, Node.js relies heavily on callbacks – functions that run after each task in the queue has been completed. Keeping a number of functions in the queue can significantly complicate the program, making it difficult to understand the code.

Quality Issues: Inconsistent API

Most Node.js developers view frequent API modifications as one of the most significant problems.

The currently available version 18.2.0 of the Node.js API has undergone numerous modifications, not all of which are backward compatible. Every time a new version of the Node.js API is released, developers must modify the available codebase to ensure compatibility.

Poor Key Typing

You won’t need a web browser on the server if you use Node.js because it lets you write JavaScript. It has looser typing requirements and the potential to execute implicit type conversion at runtime, which could lead to unexpected outcomes.

Tasks to Use Node.js

Programmers apply Node.js for JavaScript back-end development. While JavaScript is dominant in the browser, and there is no competitor to this language on the front end, the situation is different regarding the back end.

Chat

The chat program has modest processing and computing needs despite its extensive data and traffic loads. It’s the perfect use case for Node.js because it works on a wide variety of devices simultaneously. Real-time chats are used on practically every website these days. Indeed, they have reached such widespread prevalence that they are essentially required, especially for commercial websites and digital products,

The good news is that Node.js already has built-in support for the core functionalities required to create a chatting application with a real-time component. Real-time chatting services like Skype and Facebook Messenger rely on the Node.js Event API to create server-side events and push notifications.

Data Streaming

Why not use Node.js for streaming data? In conventional web platforms, developers treat HTTP requests and answers as discrete events, despite being streams. Programmers can use this observation to create some cool Node.js features.

For instance, we can process files while they are uploaded. During the upload process, we can process data in parallel as it arrives via a stream – valid for real-time audio or video encoding and proxying between several data sources.

Proxy

Consider a server-side application that interacts with third-party resources, pulls data from several sources, or stores assets (such as photographs and videos) to third-party cloud services.

Using Node instead of a dedicated proxy server could be advantageous if your proxying infrastructure does not exist or you require a local development solution. In other words, you might construct a client-side Node.js application using a Node development server for assets and proxying/stubbing API queries. Developers can handle similar interactions by a specialized proxy service (like nginx or HAProxy).

API on Top of an Object DB

Node.js suits for accessing object database information (e.g., MongoDB). When dealing with JSON-stored data, node.js can work without impedance mismatch or data conversion.

If you’re working with Rails, you’ll want to convert JSON to binary models, then expose them as JSON over the HTTP for use by frameworks like Backbone.js, Angular.js, etc., or even simple jQuery AJAX requests.

The client can access the exposed data via a RESTful API, which Node.js makes possible using JSON objects.

Application Monitoring Dashboard

If you have real-time access to visitor activity, consider how your business may expand. Tracking website visitors and seeing their interactions in real-time is made possible by nodes with WebSockets.

Gathering user data in real-time or initiating targeted interactions with your visitors by opening a communication channel at a particular stage of your sales funnel are two reasons to utilize Node.js for a monitoring dashboard.

Queued Inputs

Your database can become a bottleneck if it’s receiving a massive amount of concurrent data. Node.js can manage simultaneous connections with ease. Because database access is a blocking procedure in this instance, you may face difficulties. The approach recognizes the client’s action before adding the data to the database.

This strategy helps the system to maintain responsiveness under severe load conditions. It is especially beneficial when logging or writing user-tracking data processed in batches for later use or for activities that do not need to be reflected immediately, such as refreshing a Facebook likes count.

Brokerage/Stock Trader’s Dashboard

At the application level, trading software for brokers is another example of solutions mainly used on desktops but could easily be replaced by a real-time web solution. The trading software brokers use keeps track of stock prices, does the math and technical analysis, and makes graphs and charts.

Why not use Node.js to make a web-based solution for brokers that works in real-time? Then it would be easy for brokers to switch workstations or workplaces.

System Monitoring Dashboard

Consider a SaaS company that wants to give users a service monitoring page similar to GitHub’s status page. Using Node.js’s event loop, one can develop a robust web-based dashboard that checks the status of services asynchronously and pushes data to clients through WebSocket.

Tasks Not to Use Node.js

Despite its advantages, Node.js is not the best choice for some projects. For instance, using Node.js for simple app development makes little sense.

Server-Side Web App with a Relational Database

Node.js has numerous advantages, but its back-end relational database capabilities are not one of them. Its database utilities are less robust than those of Ruby on Rails or other frameworks. Other applications can provide far superior tools, such as data mappers, active record data-access layer implementations, and out-of-the-box data access configurations.

Heavy Server-Side Computation/Processing

It generally employs a single CPU and an event-based, non-blocking I/O mechanism. Therefore, incoming requests will be blocked if you are building an intensive CPU processing activity. The application will eventually get slowed by its number-crunching threads. In addition, Node.js will lose its speed and efficacy, perhaps its most significant advantages.

Node.js Usage for the Enterprise or Start-up

Even large businesses require scalability, speed, and usability. Therefore, it’s not a mystery why the Node.js foundation was established. Its designer, Joyant, intended to facilitate universal adoption and accelerate Node development across all industries.

IBM, Microsoft, PayPal, Fidelity, and SAP, founding members of the association, are among the major companies that use this runtime environment JS. Nearly 300 well-known firms, including Medium, Trello, Uber, and Zendesk, are now members of the foundation. As long as businesses avoid use cases that do not align with Node’s strengths, there should be no limit to what they may achieve with it.

Node.js offers a variety of benefits to start-ups too. Its inherent qualities complement the requirement for companies to be agile and easy to scale. Programmers’ access to an open-source ecosystem can assist firms in reducing their development expenses. Plus, the environment’s reliance on JavaScript considerably simplifies maintenance and compatibility. To accurately determine the budget for your project, you need to know the Node.js developer salaries.

Node.js speed and simple ability to switch nodes make it great for developers who must test new concepts and services. It is comparable to having purchased a modular home that permits you to add pieces as needed. What could be a more significant Node.js advantage for a start-up than the ability to scale up as needed?
