What is is-subdir?

The is-subdir npm package is a utility that helps determine if a given directory is a subdirectory of another directory. This can be useful in various scenarios such as validating file paths, ensuring security by restricting access to certain directories, and more.

What are is-subdir's main functionalities?

Check if a directory is a subdirectory

This feature allows you to check if a given directory is a subdirectory of another directory. In this example, '/home/user/projects/my-app' is a subdirectory of '/home/user/projects', so the function returns true.

const isSubdir = require('is-subdir');
const parentDir = '/home/user/projects';
const subDir = '/home/user/projects/my-app';
console.log(isSubdir(parentDir, subDir)); // true

Check if a directory is not a subdirectory

This feature allows you to check if a given directory is not a subdirectory of another directory. In this example, '/home/user/other-projects' is not a subdirectory of '/home/user/projects', so the function returns false.

const isSubdir = require('is-subdir');
const parentDir = '/home/user/projects';
const notSubDir = '/home/user/other-projects';
console.log(isSubdir(parentDir, notSubDir)); // false
