How to you create a directory if it doesn’t exist using node JS?

Sometimes, We need to check if a folder exists or not. Nodejs provides an inbuilt fs module that provides multiple functions.

This is an asynchronous version of the checking folder that exists or not.

Syntax.

fs.mkdirSync(path,[options])

path: the path of the folder to create options: recursive to true or false.

const fs = require("fs");

if(fs.existsSync("folder") || fs.mkdirSync("folder")){
    console.log("Folder exists")
}

The above code does not work if the path contains folder1/folder2.

For this, we need to provide below code

const fs = require("fs");
if(fs.existsSync("folder") || fs.mkdirSync("folder",{recursive:true})){
    console.log("Folder exists")
}

Similarly, It provides the mkdir() function which is an asynchronous version of a mkdirSync.

const directorypath="folder";
fs.access(directorypath, (error) => {
fs.mkdir(directorypath, { recursive: true }, (err,data) => {
    if (err) throw err;
    console.log("folder created",true)
});
