You may be using node.js in many of your projects. But do you know how to check your node.js version? If not, you've come to the right place.
Software developers work every day to add new features to their software, fix bugs, and patch vulnerabilities, because no software is perfect when it's first released. So we release different releases and use version numbers to distinguish them from each other.
Like any software, Node.js has many versions. Where do you find them? Just go to github.com/nodejs/node/releases and click on "Tags".
There are a few ways to check what version of Node you are using. You can do this using a simple command line prompt, npm or nvm. In the following article, we will show you how to check the version of Node using different methods on different operating systems.

It is a free, open-source runtime for the Go-platform that runs on JavaScript. It is specifically targeted at the server or user side of mobile applications. It is a full-stack development environment that breaks tasks into completely separate "nodes". To the question "What are the benefits of Node.js?", the reason we offer Node.js is its architecture. Of course, that is the main reason it was created, and an entire environment of dedicated open-source modules is built around it.
Whether you are developing apps for Android or iOS, Node makes these environments very valuable for programmers. Each project is split into an independent, separate Node path, allowing tasks to run seamlessly at the same time without overloading the server or consuming too much capacity.
Node.js has one key advantage: it runs on a single thread and can use non-blocking I/O calls, which allows it to handle dozens of simultaneous threads kept in an event loop.
It's important to note that Node is not the simplest single-threaded framework available; however, it is one of the most widespread and popular, and it's important to understand how this key advantage benefits you. However, the ability to scale selectively is one of the main advantages of Node.js. This feature makes it popular among developers of large, immersive apps such as mobile games, entertainment, banking, or any app that requires a lightweight, scalable solution.

Its simplicity is also beneficial for web development and design, especially when your iPhone or Android mobile app interacts with the user's Internet environment. Its fast processing can take UI/UX development to a new level. If you want to use this particular runtime environment for your mobile programs, you should be aware that Node.js has many advantages and disadvantages. We can help you understand the most important factors.
The Node.js version can have a big impact on the success of your project. Here's why:
Dependency Compatibility
Many Node.js modules and libraries depend on specific versions of Node.js. Running an incompatible version can result in errors or unexpected behavior.
Security and Stability
Older versions of Node.js may have vulnerabilities that will be fixed in newer versions. Keeping your Node.js up to date protects you from known security issues.
Access the Latest Features
New versions of Node.js offer new features, performance improvements, and better support for modern JavaScript. Staying up to date allows you to take advantage of these advancements in your projects.
Checking your Node.js version is straightforward, and the process is similar across different operating systems.
Checking Node Version on Windows
• Using Command Prompt:
• Open Command Prompt.
• Type node -v or node --version.
• Press Enter and the installed Node.js version will be displayed.
• Using Windows PowerShell:
• Open Windows PowerShell.
• Press Enter to see the version.
Checking Node Version on macOS
• Using Terminal:
• Open Terminal from the Applications folder.
• Press Enter, and the Node.js version will be shown.
Checking Node Version on Linux
• Open Terminal.
• Press Enter and you’ll see the installed Node.js version.
If you're managing multiple Node.js versions, Node Version Manager (NVM) is your best friend.
What is NVM?
NVM is a tool that allows you to install, manage, and switch between different Node.js versions effortlessly.
Installing NVM on Your System:
To install NVM into your system, you need to follow the instructions that are provided on the NVM GitHub page.
Using NVM to Check Node Version:
Once NVM is installed, you can check your Node version by typing ‘nvm ls’ in the terminal. This will display all installed Node.js versions on your system, with the current version highlighted.
Keeping Node.js updated is essential for security and access to new features.
Updating Node on Windows
• To update Node on your windows PC, download the latest Node.js installer from the official Node.js website.
• After that, run the installer and follow the prompts to complete the installation.
Updating Node on macOS
• Use Homebrew to update Node.js by running ‘brew update’ followed by ‘brew upgrade node’.
Updating Node on Linux
• Depending on your Linux distribution, you can update Node.js using package managers like apt or yum. For example, on Ubuntu, you can use ‘sudo apt-get update’ followed by ‘sudo apt-get upgrade nodejs’.
Using NVM to Update Node.js
• Simply run ‘nvm install node’ to get the latest version of Node.js.
Sometimes, checking your Node.js version might not be as straightforward. Here are some common issues:
Version Command Not Recognized:
If ‘node -v’ or ‘node --version' doesn't work, it might be due to an incorrect installation or path configuration. Reinstalling Node.js or adjusting your system’s PATH variable may help.
Different Versions in Different Environments:
If you’re using virtual environments or containers, the Node.js version might differ from your local environment. Always check the version within the specific environment you’re working in.
Troubleshooting Tips:
If you encounter issues, try reinstalling Node.js or using NVM to manage your versions. Checking online forums and communities like Stack Overflow can also provide helpful solutions.
