is-subdir

is-subdir

Return whether a directory is a subdirectory of another directory

Cross-platform. Works correctly on Windows, where directory paths can start with disk drive letters in different casings. Like c:\foo and C:\foo\bar.

Returns true when the directories match. The isSubdir.strict() variant only returns true if the second parameter is a strict subdir of the first and not the same.

Installation

<npm|yarn|pnpm> add is-subdir

Usage

'use strict'
const path = require('path')
const isSubdir = require('is-subdir')

console.log(isSubdir(process.cwd(), path.resolve('node_modules')))
//> true
console.log(isSubdir.strict('node_modules/tape', '../tape'))
//> false

API

isSubdir(parentDir, subdir): boolean

isSubdir.strict(parentDir, subdir): boolean
