How To Check Node Version on Your System? (Ways To Check Node Version)
There are multiple ways to check the Node version running on your system. The following methods can help you find the Node version you are using on different operating systems:
- Check the Node.js version using the node version command node --version or the shorthand node -v.
- Check Node version at runtime using process.version property.
- Manage and check the Node version using NVM.
How To Check Node.js Version on Linux?
Node.js can be installed and run on multiple operating systems, such as Linux, Windows, and macOS. Over time, several Node.js releases have been made available for installation. The best version for you would depend on your specific application needs.
You can check the Node version installed on your system by running the following command:
$ node --version
It will display the Node version on your command-line window running on your system.
If you don’t have Node.js installed on your Linux system, don’t worry! In this section, we will guide you on how to check Node version with complete Node.js installation on Linux.
You can install Node.js on the Linux Ubuntu distribution using the following steps.
Step 1: Update Your Repositories
Before starting the Node.js installation on your system, ensure that all your Linux system repositories are up to date. Launch the terminal using ‘Ctrl+Alt+T’ or open it from the application menu.
Now, update apt repositories using the below command:
$ sudo apt update
Step 2: Install Node.js and NPM
Install Node.js on your Linux system by executing the below command:
$ sudo apt install node
Always install the NPM (Node Package Manager) with Node.js or node server. NPM allows you to install open-source libraries and Node.js packages on your system.
You can install NPM along with the Node.js using this command:
$ sudo apt install Node.js npm
To check the NPM version, you can use the below command:
$ npm –version
Step 3: Verify Node.js Installation
You can verify the Node.js installation on your system using the following command:
$ node –version
Alternatively, you can also check the node version using the node command:
$ node -v
Both commands will display the installed Node.js version on your terminal screen. Using the above method, you can also check the Node.js version on bluevps for Linux.
To uninstall or remove the Node.js version, use the below-mentioned command:
$ sudo apt remove node.js
How To Check Node Version on Windows?
For Windows users, it's straightforward to install and check Node.js on the system. Before we proceed, ensure you have administrative privileges to run commands on the command prompt. If Node.js isn't yet installed on your Windows OS, follow these steps:
Step 1: Download the Node.js MSI Installer
Go to the official Node.js website and select the appropriate Node.js Windows Installer based on your system architecture:
- For a 64-bit system, choose the x64-bit installer.
- For a 32-bit system, choose the x32-bit installer.
In this guide, we'll be downloading the stable version, node-v18.14.0.
Step 2: Launch the Installer
After completing the download, navigate to the folder or directory where you store the Node.js installer. You will double-click on the installer to launch the installation wizard.
Step 3: Start the Setup Wizard
The Node.js setup wizard will launch on your system. Click ‘Next’ to proceed.
Step 4: Accept the License Agreement
Accept the terms of the End User License Agreement and click ‘Next.’
Step 5: Choose Installation Path
Select the desired folder for Node.js installation. If you prefer the default path, simply click 'Next.'
Step 6: Additional Tools
If you want to install tools necessary to compile native modules, mark the checkbox and click ‘Next.’
Step 7: Begin Installation
Now, your setup is ready for installation. Click ‘Install’ to start the Node.js installation on your Windows system.
Step 8: Complete the Installation
Once you complete the Node.js installation on your system, click ‘Finish’ to close the Node.js setup wizard.
With Node.js installed, you can now verify to get Node version. Open the command prompt and enter:
> node --version
> node -v
Both commands will display the installed Node.js version on your Windows system.
How To Check Node Version Using Console.Log? (Process.Version Property)
Once you install Node.js on your system, you can check the current Node release using the process.version property. To check Node version using console.log, type the ‘node’ command on the command prompt and then execute the following statement:
The above command will open the Node terminal on the command prompt. Now, check the currently installed Node.js version:
Alternatively, you can also directly get the node version at runtime using the built-in ‘process.version’ property:
You can get the versions of Node modules, including all dependencies, using the ‘process.versions’ property. Run this command on the command prompt:
The above command will return an object that will contain information about versions of the Node.js module and Node dependencies.
How To Manage the Node.js Version Using NVM?
You can install Node.js on your Linux system using NVM (Node Version Manager). To do this, download the bash script file on your Linux system:
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
Source the downloaded bash script:
$ source ~/.bashrc
Now, list the available Node.js --versions using the nvm command:
$ nvm list-remote
Choose the latest or specific Node.js version and install it running the below command:
$ nvm install v20.5.1
Check Node.js version, which is currently installed on your Linux system.
Throughout this guide, we delved into methods to determine the Node.js version on both Linux and Windows platforms. We explored the direct approach using the node version command node --version or node -v, as well as retrieving the Node.js version at runtime with the integral process.version property.
So, having a firm grasp of Node.js and its intricacies is pivotal for modern developers aiming to produce efficient and responsive web applications.
