Node.js process.getuid() Method

The process.getuid() method is an inbuilt application programming interface of the process module which is used to get the numerical user identity of the Node.js process. Syntax:

process.getuid()

Parameters: This method does not accept any parameters. Return Value: This method returns an integer value specifying the numerical user identity of the Node.js process. Note: This method will only work on POSIX platforms. Not available on windows or android platforms so will cause an error i.e. TypeError, getuid is not a function. Below examples illustrate the use of process.getuid() method in Node.js: Example 1: javascript

// Node.js program to demonstrate the     
// process.getuid() method  
 
// Include process module
const process = require('process');

// Printing the numerical user 
// identity of the Node.js process
console.log(process.getuid());

Output:

6693036

Example 2: javascript

// Node.js program to demonstrate the     
// process.getuid() method  
 
// Include process module
const process = require('process');

// Check whether the method exists or not
if (process.getuid) {
  
  // Printing getuid() value
  console.log("The numerical user identity "
            + "of the Node.js process: "
            + process.getuid());
}

Output:

The numerical user identity of the Node.js process: 6693036

Note: The above program will compile and run by using the node filename.js command. Reference: https://nodejs.org/api/process.html#process_process_getuid
