Knowing your Node.js version is crucial for managing projects and ensuring compatibility. This guide shows you how to quickly check your Node.js version using the Windows command prompt (cmd). Whether you're a seasoned developer or just starting, this simple process will become a regular part of your workflow.

Opening the Windows Command Prompt

Before we begin, make sure you have Node.js installed on your Windows machine. If not, download and install it from the official Node.js website.

To open the command prompt:

1. Search for "cmd" in the Windows search bar.
2. Select "Command Prompt" from the results. This will open a new cmd window.

Checking Your Node.js Version

Once the command prompt is open, type the following command and press Enter:

node -v

or

node --version

Both commands achieve the same result. The -v or --version flag tells Node.js to display only its version number.

The output will display the installed Node.js version number, for example:

v16.17.0

This indicates you have Node.js version 16.17.0 installed. Make a note of this version – it’s essential for troubleshooting and dependency management.

Checking npm Version (Node Package Manager)

Node.js comes bundled with npm (Node Package Manager), which is used to install and manage packages. You can check your npm version using this command:

npm -v

or

npm --version

This will output your npm version number, similar to the Node.js version output. Keeping both Node.js and npm updated is best practice.

Troubleshooting

If you get an error message like "'node' is not recognized as an internal or external command, operable program or batch file.", it means Node.js is not correctly installed or is not in your system's PATH environment variable. You may need to reinstall Node.js, ensuring you select the option to add Node.js to your PATH during installation. Alternatively, you might need to manually adjust your system's PATH environment variable to include the Node.js installation directory.

Keeping Node.js Updated

Regularly updating Node.js and npm is vital for security and access to the latest features. You can update Node.js using a Node Version Manager (nvm) or by downloading the latest installer from the official Node.js website. npm updates typically happen automatically when you install or update packages. You can also force an npm update using npm update -g npm.

This comprehensive guide ensures you can efficiently check your Node.js and npm versions in Windows cmd, a fundamental skill for any Node.js developer. Remember to keep your versions updated for optimal performance and security.
