What’s the reason behind it?
It depends. Though, there can be objective reasons. Like, Node.js cannot achieve certain things that other server-side technologies can do. Some misconceptions about Node.js stops people from trying out the platform.
If you’re one of those who hesitate to try Node.js because of myths, this article is for you.
Here we will discuss some common myths about Node.js and the truth behind those myths.
Node.js is only for small projects.
Node.js is a powerful technology that can handle large-scale, high-traffic applications and small projects. Big companies like Netflix, Uber, and PayPal have used Node.js for their web applications. Because of this reason, many of these companies and agencies consider outsourcing Node.js development work or hiring Node.js developers.
Node.js is suitable for large-scale applications because it uses an event-driven, non-blocking I/O model, which allows it to handle multiple connections simultaneously, making it highly efficient and scalable.
Additionally, Node.js is built on JavaScript, a widely-used programming language with a large and active community that provides extensive documentation and support. Node.js is also well suited for microservices architecture, a popular approach for building large-scale, complex applications.
Node.js is not suitable for building a backend for Machine learning and AI
Some developers and Node.js development companies may perceive that Node.js is unsuitable for building backends for machine learning and AI models, but this is only partially true. Node.js offers a wide range of libraries and frameworks that can be used to build backends for machine learning and AI models.
For example, Tensorflow.js is a library developed by Google that can be used to train and run machine learning models in the browser or a Node.js environment,
Node.js can be integrated with other technologies, such as Python and R, widely used for machine learning and AI development. For example, with the help of libraries like ‘python-shell’ and ‘node-r-script’, Node.js can execute commands and scripts written in Python and R, respectively.
Node.js is not secure.
Node.js has a reputation for being insecure, but this is not entirely true. Node.js has a built-in security feature called the “sandbox” that isolates the application from the underlying system, making it secure. Additionally, many security-related modules are available in the Node.js ecosystem to help developers build secure applications.
For example, the “helmet” module can be used to secure HTTP headers, while the “csurf” module can be used to prevent cross-site request forgery (CSRF) attacks.
Furthermore, Node.js has a built-in module for handling encryption and decryption, called “crypto,” which can be used to secure sensitive data.
However, it’s important to note that Node.js is a platform that requires the developer to handle security, just like any other platform. Therefore, it’s always a good idea to use best practices and stay up-to-date with security patches and updates.
Node.js is not suitable for real-time applications.
Node.js is built on an event-driven architecture that makes it perfect for real-time applications such as chat and gaming. In addition, its non-blocking I/O model allows for fast and efficient handling of multiple connections simultaneously, making it ideal for real-time applications.
Node.js has a built-in module called “socket.io”, which can easily build real-time applications. This module allows for easy implementation of bi-directional communication, automatic reconnection, and real-time data transfer.
Node.js is well suited for building real-time applications that require low latency, such as online gaming, stock trading platforms, and instant messaging systems. Issues that affect any application’s performance like high latency, recurrent bugs, memory leaks, server downtime, and several others can be fixed by Node.js monitoring as it aids the process and ensures real-time monitoring.
Node.js does not support multi-threading
Node.js does not have built-in support for multi-threading, but it can be achieved through worker threads. This allows for parallel execution of code, making it possible to perform heavy computation tasks in the background. At the same time, the main thread handles the client requests.
The worker_threads module, which is built-in in Node.js, allows you to create additional threads that can run alongside the main Node.js event loop, allowing you to take full advantage of multi-core systems without the need to use any other libraries.
Node.js also supports process-level concurrency through its child_process module, which allows the creation of new processes that can run alongside the main process and communicate with it through IPC mechanisms.
Node.js is not suitable for CPU-intensive tasks.
Node.js is not recommended for CPU-intensive tasks because of its single-threaded nature. However, it can be combined with other technologies, such as C++ or Rust, to perform such tasks.
For example, Node-addon-API allows you to create C++ modules that can be loaded into a Node.js process and used as if they were JavaScript modules this way. The CPU-intensive task can be offloaded to the C++ module.
Node.js does not have a good performance.
Node.js is known for its fast performance and efficient handling of multiple connections. In addition, its event-driven architecture and non-blocking I/O model make it a perfect choice for high-performance web applications.
Node.js has a built-in module called “cluster” that can be used to create multiple worker processes. Each worker process runs on a separate CPU core and shares the same server port, allowing for efficient load balancing and improved performance.
Also, Node.js uses a V8 JavaScript engine developed by Google, which is known for its high performance and efficient memory management.
Node.js is difficult to learn.
Node.js is a simple and easy-to-learn technology. Its syntax is similar to JavaScript, a widely-used programming language. In addition, it has a large and active community that provides extensive documentation and support.
Additionally, Node.js has a built-in package manager called npm, which makes it easy to install and manage third-party modules. Finally, many online tutorials and courses make it easy for developers to learn and start building applications with Node.js.
Furthermore, the Node.js community is constantly updating and adding new features to the platform, making it easier for developers to stay updated with the latest trends and best practices.
Node.js is not suitable for enterprise applications.
Node.js is often perceived as a technology for small projects or startups. Still, it can also build large-scale, complex enterprise applications. In addition, it has a large and active community that provides extensive documentation and support, making it easy for developers to stay updated with the latest trends and best practices.
To build robust and secure enterprise applications, node.js can be integrated with other technologies, such as databases, cloud services, and security tools.
Node.js is only good for web development.
While Node.js is primarily used for web development, it can also be used for other applications, such as desktop and mobile app development, IoT development, and even robotics and drones.
Node.js can build cross-platform desktop applications using frameworks such as Electron and nw.js. It can also build mobile applications using frameworks like React Native and Native Script. Additionally, Node.js’s event-driven and non-blocking I/O model suits IoT development well, as it can handle the high number of connections and real-time data transfer required by IoT devices.
The Bottomline
It’s important to note that, like any technology, Node.js has its strengths and weaknesses. However, many myths surrounding Node.js are based on misconceptions or outdated information.
