Creating and removing directories in Node.js - Quick Revision & Summary

Recall & Review

beginner

What Node.js module do you use to create and remove directories?

You use the fs module, which provides functions like mkdir to create and rmdir or rm to remove directories.

intermediate

How do you create a directory including any missing parent folders in Node.js?

Use fs.mkdir(path, { recursive: true }). The recursive: true option creates all missing parent directories automatically.

intermediate

What is the difference between fs.rmdir and fs.rm when removing directories?

fs.rmdir removes empty directories only. fs.rm with { recursive: true } can remove directories with files inside.

beginner

What happens if you try to create a directory that already exists without the recursive option?

Node.js will throw an error because the directory already exists. Using { recursive: true } prevents this error by ignoring existing directories.

advanced

How can you remove a directory and all its contents safely in Node.js?

Use fs.rm(path, { recursive: true, force: true }). This removes the directory and everything inside it without throwing errors if the directory doesn't exist.

Which option makes fs.mkdir create all missing parent directories?

A { recursive: false }

B { recursive: true }

C { force: true }

D { createParents: true }

The option { recursive: true } tells Node.js to create all missing parent directories.

Which method removes a directory only if it is empty?

A fs.mkdir

B fs.rm with recursive

C fs.rmdir

D fs.unlink

fs.rmdir removes empty directories only.

What does fs.rm(path, { force: true }) do?

A Removes a directory and ignores errors if it doesn't exist

B Creates a directory forcibly

C Removes files only

D Throws error if directory doesn't exist

The force: true option ignores errors if the directory or file does not exist.

If you try to create a directory that exists without recursive option, what happens?

A Directory is overwritten

B Parent directories are created

C Directory is ignored silently

D Error is thrown

Node.js throws an error if the directory exists and recursive option is not used.

Which Node.js module provides directory creation and removal functions?

A fs

B path

C http

D os

The fs module handles file system operations including directories.

Explain how to create a directory and all its missing parent directories in Node.js.

Think about the option that allows creating multiple levels of folders at once.

Describe the difference between removing an empty directory and removing a directory with files inside in Node.js.

Consider which methods allow deleting directories with content and which do not.
