The company’s software must be efficient and robust for which the use of the right tech stack is essential. One such effective technology is JavaScript. It is one of the leading client-side programming languages. Over time, it has become the top cross-platform web application development tool for web developers. Many different frameworks and environments work on JavaScript which has created a huge shift in web app development. For instance, Node.js. It comes with immense advantages. To learn more about Node.js and how advantageous Node.js development services are, let’s go through this blog.

1. What is Node.JS?

Node.js is a very popular cross-platform runtime environment that is based on Chrome’s V8 JavaScript code. It was introduced by Ryan Dahl in the year 2019. It is an open-source platform that enables developers to create real-time web applications. Because of its features and non-blocking asynchronous architecture, Node.js has become very popular in a very short period. Giants like Uber, Netflix, Walmart, and eBay are using the benefits of Node.js for their web apps. It makes the web development process very smooth and efficient.

2. What is Node.js Used for?

There are many reasons to use Node.js for your different projects. Here are some:

2.1 API

A RESTful or GraphQL API can be created with relative ease, as  node.js    has a robust library support system. In the past, Node.js was only suggested for low-volume, high-CPU-intensive applications. Worker threads have made this possible since version 10.5.0.

2.2 Streaming Web Applications

Videos and music are often consumed via streaming platforms. Node.js has a built-in streams module that allows you to process large amounts of data sequentially. This eliminates the need for any kind of temporary storage or caching in your program memory. Since video encoding can be done on the server, clients won’t have to worry about it.

2.3 Video Gaming

The fast reaction time of the platform is particularly useful for multiplayer games and virtual emulators since it simplifies communication between a large number of participants and the execution of different scenarios. 

2.4 Command Line Tools

NPM offers a wide array of packages that may be used to create more complex tools in addition to standard command-line utilities.

2.5 Real-Time Web Applications

Real-time online applications, such as a chat room where users can communicate with one another in real-time, can be built using Node.js since it can manage a large number of I/O operations efficiently. Node’s Web Sockets and Events API make this a reality. When it comes to building websites, Node js is at ease.

2.6 Microservices

This approach to developing apps has gained a lot of traction in the past several years. Since Node.js is lightweight and simple to implement, it can be used to quickly expand your solution. When developing and managing our microservices, Node.js is a go-to technology. Many businesses choose Node.js as part of their transition to microservices. 

3. Advantages of Using Node

As we all know, Node.js is continuously growing and gaining massive popularity for web app development, but now its capabilities have grown even more because it offers a variety of benefits for backend development. It is a great platform for real-time application development and managing huge amounts of information. 

Advantages of Using Node

Let’s discuss the advantages of Node.js in detail:

3.1 Scalable Web App Development

Node.js was built with scalability in mind. It allows multiple threads to run simultaneously and interact with each other which is superior to other web backend development solutions. It has a cluster module that is responsible for load balancing for every CPU-bound task. This is one of the main Node.js advantages. You can run more than one node at a time and the cross-platform runtime environment will automatically balance the workload.

Node.js allows horizontal partitioning and divides your app into small instances. You can show various versions of the mobile apps to users based on their interests, age, location, language, etc. which reduces workload and increases personalization. Node.js child processes operate quickly and interact with each other to share the same origin.

3.2 High Performance

Node.js is popular for providing excellent performance and facing considerable amounts of data to process at the same time. It is a perfect choice for backend development that interprets the JavaScript code using Google’s V8 JavaScript engine. Node.js web app development engine helps to compile the code into machine code directly, making it easier and faster to write server-side code and implement it. 

The backend Node.js technology accelerates code execution and its runtime environment supports non-blocking I/O operations. As a single-threaded event loop, it uses multiple worker threads in the background to execute the asynchronous programming code and nonblocking which means the callback function is delegated to the event loop but executed by different threads.

3.3  Cost-Effective with Full-Stack JavaScript

With Node.js, JS developers can effortlessly create both server-side and client-side JavaScript applications. One of the finest things about node.js is how it increases development speed and reduces the cost and effort needed to build a project by eliminating the need to hire two resource teams.

After migrating from Ruby on Rails to Node.js, LinkedIn’s development team saw a significant boost in performance. They went from thirty web servers to only three. They began more effectively allocating and utilizing available resources and moved their attention from problem-solving to app development.

3.4 Powerful Data Processing

Node.js is a backend development language and runtime environment capable of processing thousands of requests simultaneously. It is a perfect choice for efficient data-handling tools. Many backend development platforms use synchronous processing for handling requests where they each wait to process CPU-bound tasks one by one. It refuses the traditional system and adopts an asynchronous structure for upcoming requests to process together with the first one. 

There are two approaches to software development: linear and event-based programming. A linear tool helps to execute algorithms in a queue regardless of users’ actions. Event-based programming doesn’t have a specific output order and there are useful background operations.

3.5 Easy to Learn and Quick to Adapt

If a programmer is familiar with JavaScript, making the switch to Node.js for server-side work is a simple process. This is appealing to novice programmers since the runtime environment is simple to pick up.

It’s more like a general-purpose language in the software development industry. Even if the programmer is a newbie or junior developer, they won’t need to spend any additional time studying NodeJS.

3.6 Concurrent Request Handling

With Node.js, handling multiple concurrent users simultaneously in a single go is possible. And this is one of the biggest advantages of Node.js. Its capacity to handle multiple requests at once for any type of complex and extensive web application has made it popular among Javascript developers. Besides, the majority of eCommerce businesses prefer Node.js for their application for this reason. 

3.7 Lesser Loading Time

Node.js comes with a caching module that helps in reducing the overall loading time. Developers can execute the code without any hassle. Besides, having a caching module helps the web app get a request easily and then transfer it to in-app memory. This enables the user to get results on web pages in a few microseconds without waiting much.

All these benefits of node.js contribute towards making nodejs a favorable choice for developers for their development projects. On the other hand, there are certain disadvantages of node.js that will affect your decision to choose a node. These disadvantages of node js are as under.

3.8 Large and Active Community Support

With thousands of professionals actively participating in the Node.js community, you can rely on assistance from specialists all around the world to help you work through even the most unusual programming issues.

For JavaScript, the most used package manager registry is NPM. It provides easy access to a wide variety of free tools and libraries that can be integrated into your work. There is a wealth of developer-created resources on GitHub that can help you get more done while spending less time and money.

Many of the world’s most well-known technology companies, including Amazon, Google, Facebook, and Netflix, are strong supporters of the node.js community and have contributed significantly to its success. They’ve contributed much by creating several open-source alternatives. The future of technology depends on it being adopted by major tech companies and the development community.

3.9 Helps in Building Cross-Platform Applications

Using frameworks like Electron and NW.js, Node.js enables the development of cross-platform, real-time online apps. This simplifies the time-consuming process of creating multiple sets of code for various desktop operating systems. Your team won’t require experts in Objective-C, C#, or any other language in the future to build native desktop applications. 

In addition, the Google Chrome Developer Tools can potentially be used by your Node.js developers for any purpose, including coding, debugging, and building. This efficient method is fundamental to modern web development using Javascript front-end frameworks like AnjularJS, Vue.js, and React and back-end frameworks like Node.js. It has made it possible for full-stack developers to reap the benefits of and explore the opportunities presented by node.js.

4. Disadvantages of Using Node

Disadvantages of Using Node

4.1 Asynchronous Programming Model

To get a scalable app the developer needs a technology that has an asynchronous programming model. However, some developers may feel that it is a difficult programming model in comparison to the linear blocking I/O programming. Therefore,  fewer programmers are choosing Node.js as their development framework.

4.2 Doesn’t have a Strong Library Support System

JavaScript does not come with a well-equipped library system compared to other universal programming languages. This results in developers being forced to take support of a common library for various tasks like processing the images, Object-Relational Mapping (ORM), handling database operations, and more.

4.3 Unstable API

In Node.js there are frequent  API changes. API stands for Application Programming Interface and it keeps on changing. Every new API comes with backward-incompatible changes. This means that the developers will have to change the code to make it compatible with the latest version of the Node.js API.

4.4 Reduces Performance when Handling Heavy Computing Tasks

Node.js has certain benefits from being single-threaded and event-driven, but it has several drawbacks when it comes to doing heavy CPU-intensive tasks.

Node.js will use all of its CPU power to complete a large CPU-driven job received in the event loop. This slows down the application’s event loop as a whole, making the user interface less responsive.

To address this issue, Node.js added the “worker threads” module in 2018. This made it possible for programmers to run several threads at once. However, you will still need other tools to cope with CPU-bound computing problems, and this method does not provide them altogether.

5. Conclusion

As seen in this blog, Node.js has a lot of advantages rather than disadvantages and it is because of its architecture, features, and active community support. This is why developers prefer to use Node.js in the maximum number of projects that fall in its requirement range. Besides, as Node.js has JavaScript, it can be used for both frontend and backend servers which is a big plus. So, if you want to take your client’s project to a greater height, Node.js is the best technology.
