nodejs get prosses id

To get the process ID in Node.js, you can use the process.pid property.

The process object is a global object in Node.js that provides information and control over the current Node.js process. The pid property of the process object represents the process ID of the current Node.js process.

Here are the steps to retrieve the process ID in Node.js:

1. First, you need to require the process module in your Node.js application by using the following code:

const process = require('process');

The require function is used to import the process module, which is a built-in module in Node.js.

1. After requiring the process module, you can access the process ID by using the process.pid property. Here's an example of how to retrieve the process ID:

const processId = process.pid;

This code assigns the process ID to the processId variable.

1. Finally, you can use the processId variable to perform any necessary operations with the process ID.

That's it! You have successfully retrieved the process ID in Node.js using the process.pid property.
