nodejs get cpu count

To get the CPU count in Node.js, you can use the built-in os module. Here are the steps to achieve this:

1. Import the os module: To use the os module, you need to import it into your Node.js script. You can do this by adding the following line of code at the beginning of your script:

const os = require('os');

1. Access the CPU information: In order to retrieve the CPU count, you need to access the CPU information provided by the os module. You can do this by using the os.cpus() method, which returns an array of objects representing each CPU core.

const cpus = os.cpus();

1. Get the CPU count: To obtain the CPU count, you can simply use the length property of the cpus array, which will give you the number of CPU cores available on the current system.

const cpuCount = cpus.length;

1. Display the CPU count: Finally, you can display the CPU count by logging it to the console or using it however you need in your code.

console.log('CPU count:', cpuCount);

That's it! By following these steps, you can retrieve the CPU count in Node.js using the os module.
