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
