Creating folder and files using node js

by shivanisanju03 Updated: Mar 21, 2023

Guide Kit

We can create files and folder using node js by using fs.Access() and its promise-base fsPromises.access() counter part) to know whether the folder exists and also if Node.js can access it with permissions

There are methods in file system module to create new files, they are:

fs.appendFile()
fs.open()
fs.writeFile()

To create a new folder , we can use fs.mkdir() or fs.mkdirSync or fsPromises.mkdir() .
