Node.js fs.mkdtempSync() Method

Last Updated : 12 Oct, 2021

The fs.mkdtempSync() method is an inbuilt application programming interface of fs module which provides an API for interacting with the file system in a manner closely modeled around standard POSIX functions. The fs.mkdtempSync() method creates a unique temporary directory. This is the synchronous version of fs.mkdtemp() method.

Syntax:

fs.mkdtempSync( prefix, options )

Parameters: This method accept two parameters as mentioned above and described below:

Prefix: The six random characters are appended behind the prefix to create a unique temporary directory.
Options: It is an optional parameter that can be a string specifying an encoding, or an object with an encoding property specifying the character encoding to use.

Return value: It returns the created folder path.

Below examples illustrate the use of fs.mkdtempSync() method in Node.js:

Example 1:

// Node.js program to demonstrate the     
// fs.mkdtempSync() method     
       
// It includes fs module          
const fs = require('fs');     
  
// It includes os module          
const os = require('os');     
  
// It includes path module          
const path = require('path'); 
           
// Return the created folder 
console.log(fs.mkdtempSync( 
    path.join(os.tmpdir(), 'foo-'))); 

Output:

/tmp/foo-OkEvul

Example 2:

// Node.js program to demonstrate the     
// fs.mkdtempSync() method     
       
// It includes fs module          
const fs = require('fs'); 
  
// It includes os module 
const os = require('os'); 
  
const tmpDir = os.tmpdir(); 
  
const { sep } = require('path'); 
  
// Print something similar to `/tmp/abc123`. 
// A new temporary directory is created within 
// the /tmp directory. 
console.log(fs.mkdtempSync(`${tmpDir}${sep}`)); 

Output:

/tmp/bGVto1
