common-ancestor-path

Find the common ancestor of 2 or more paths on Windows or Unix

USAGE

Give it two or more path strings, and it'll do the thing.

const ancestor = require('common-ancestor-path')

// output /a/b
console.log(ancestor('/a/b/c/d', '/a/b/x/y/z', '/a/b/c/i/j/k'))

// normalizes separators, but NOT cases, since it matters sometimes
console.log(ancestor('C:\\a\\b\\c', 'C:\\a\\b\\x'))

// no common ancestor on different windows drive letters
// so, this returns null
console.log(ancestor('c:\\a\\b\\c', 'd:\\d\\e\\f'))

API
