how to get os information nodejs
To get OS information in Node.js, you can use the built-in os
module. Here are the steps to retrieve OS information:
Import the
os
module by adding the following line at the beginning of your code:javascript const os = require('os');
To get the operating system's hostname, use the
os.hostname()
method. This method returns the hostname of the operating system as a string.javascript const hostname = os.hostname();
To get the operating system's type, use the
os.type()
method. This method returns the operating system's name as a string.javascript const osType = os.type();
To get the operating system's platform, use the
os.platform()
method. This method returns the platform of the operating system as a string.javascript const platform = os.platform();
To get the operating system's release, use the
os.release()
method. This method returns the release of the operating system as a string.javascript const release = os.release();
To get the operating system's architecture, use the
os.arch()
method. This method returns the architecture of the operating system as a string.javascript const architecture = os.arch();
To get the operating system's total memory, use the
os.totalmem()
method. This method returns the total amount of system memory in bytes.javascript const totalMemory = os.totalmem();
To get the operating system's free memory, use the
os.freemem()
method. This method returns the amount of free system memory in bytes.javascript const freeMemory = os.freemem();
Finally, you can log or use the retrieved OS information as needed. For example:
javascript console.log('Hostname:', hostname); console.log('OS Type:', osType); console.log('Platform:', platform); console.log('Release:', release); console.log('Architecture:', architecture); console.log('Total Memory:', totalMemory); console.log('Free Memory:', freeMemory);
Please note that the values returned by these methods may vary depending on the operating system and hardware you are using.
I hope this helps! Let me know if you have any further questions.
