How to Check Node JS Version?
Below are the three methods by which you can check Node JS versions on your computer system:
Method 1 – Using Command Line Interface (CLI)
To determine the version of Node JS installed on your system using the Command Line Interface (CLI), you can follow these simple steps:
- Open the command prompt, input the command “node -v” and hit ENTER. This command is specifically designed to retrieve the installed version of Node JS.
- After executing the command, the terminal or command prompt will present the version number of Node JS installed on your computer.
- if you have multiple versions of Node JS installed on your system, the command will indicate the presently active version.
- To view all the installed Node JS versions, you can use the command “nvm ls” if Node Version Manager (NVM) is installed. NVM facilitates the management of multiple Node JS versions on your computer.
Method 2 – Using Process Object
In order to determine the version of Node JS within a Node JS environment, strict adherence to the ensuing steps is of utmost importance:
- Using the require () function, begin by importing the built-in ‘process’ module in Node JS using the require() function. Add this code at the top of your file:
const process = require('process');
- Next, access the ‘version’ property of the process object. This property contains the version information of the Node JS runtime:
const nodeVersion = process.version;
- To display the Node JS version on the console, use the console.log() function. Insert the following line of code:
console.log('Node JS version:', nodeVersion);
- The console output will display the Node JS version, indicating the installed version of Node JS.
Method 3 – Using package.json File
Below are the mentioned steps that you must follow to know the Node JS version using the package.json file. The package.json file is a vital component of any Node JS project, containing essential details such as dependencies, scripts, and metadata.
- Open the command prompt or terminal, use the ‘cd’ command, and use the root directory of your Node JS project.
- Once you are in the project directory, you can locate the package.json file. If it is not present, ensure you are in the correct directory or initialize a new Node JS project using the ‘npm init’ command.
- Open the package.json file using a text editor or your preferred code editor.
- Look for the “engines” section within the file. If it is not present, you can manually add it.
- Within the “engines” section, you will find a property called “node”. The value of this property specifies the required Node JS version for your project.
- The Node JS version is typically indicated using the semantic versioning format, such as “node”: “>=12.0.0”. Take note of the Node JS version specified in the “node” property.
