Hello, fellow developers and tech enthusiasts!
Are you starting a new Node.js project or simply curious about the Node.js version installed on your machine? Knowing your Node.js version is crucial for compatibility with various packages and ensuring your development environment is up to date. Don’t worry if you’re not a tech guru—this guide will walk you through the process step by step.
Why You Need to Know Your Node.js Version
Before we dive in, let’s quickly touch on why it’s important to know your Node.js version. Different projects might require specific Node.js versions to run correctly.

How to Check Node.js Version
Checking your Node.js version is a straightforward process. Here’s how you can do it:
Step 1: Open Your Terminal or Command Prompt
The first step is to open your terminal (on macOS or Linux) or command prompt (on Windows). You can do this by searching for “Terminal” or “Command Prompt” in your applications or using shortcuts like Ctrl + Alt + T on Linux and macOS, or Win + R and then typing cmd on Windows.
Step 2: Type the Command
In the terminal or command prompt, type the following command and press Enter:
node -v
Step 3: Read the Output
After you press Enter, you should see something like this:
v14.17.0
This output indicates that your Node.js version is 14.17.0. The exact version number will vary depending on what’s installed on your system.
Additional Tips

For macOS and Linux:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
For Windows, you can use nvm-windows.
Switching Node.js Versions with nvm
Once nvm is installed, you can install a new version of Node.js like this:
nvm install 16.3.0
To switch to a different version:
nvm use 16.3.0
To check the currently active Node.js version:
nvm current
