OSCC · JavaScript, Node · Oct 22, 2020

Creates a directory, if it does not exist.

• Use fs.existsSync() to check if the directory exists, fs.mkdirSync() to create it.

const fs = require('fs');

const createDirIfNotExists = dir =>
  !fs.existsSync(dir) ? fs.mkdirSync(dir) : undefined;

createDirIfNotExists('test');
// creates the directory 'test', if it doesn't exist
