common-path-prefix

Computes the longest prefix string that is common to each path, excluding the base component. Tested with Node.js 8 and above.

Installation

npm install common-path-prefix

Usage

The module has one default export, the commonPathPrefix function:

const commonPathPrefix = require('common-path-prefix')

Call commonPathPrefix() with an array of paths (strings) and an optional separator character:

const paths = ['templates/main.handlebars', 'templates/_partial.handlebars']

commonPathPrefix(paths, '/') // returns 'templates/'

If the separator is not provided the first / or \ found in any of the paths is used. Otherwise the platform-default value is used:

commonPathPrefix(['templates/main.handlebars', 'templates/_partial.handlebars']) // returns 'templates/'
commonPathPrefix(['templates\\main.handlebars', 'templates\\_partial.handlebars']) // returns 'templates\\'

You can provide any separator, for example:

commonPathPrefix(['foo$bar', 'foo$baz'], '$') // returns 'foo$''

An empty string is returned if no common prefix exists:

commonPathPrefix(['foo/bar', 'baz/qux']) // returns ''
commonPathPrefix(['foo/bar']) // returns ''

Note that the following does have a common prefix:

commonPathPrefix(['/foo/bar', '/baz/qux']) // returns '/'
