Sometimes, we want to create a directory if it doesn’t exist using Node.js.

In this article, we’ll look at how to create a directory if it doesn’t exist using Node.js.

How to create a directory if it doesn’t exist using Node.js?

To create a directory if it doesn’t exist using Node.js, we can use the existsSync method to check if a directory exists.

And then we can use the mkdirSync method to let us create the directory.

For instance, we write

const fs = require('fs');
const dir = './tmp';

if (!fs.existsSync(dir)) {
  fs.mkdirSync(dir);
}

to require the fs module.

Then we call fs.existsSync with dir to check if a folder with the path given in dir exists.

If it does, it returns false.

And we call mkdirSync with the dir path to create a directory with the path if the directory doesn’t exist.
