is-absolute    

Returns true if a file path is absolute. Does not rely on the path module and can be used as a polyfill for node.js native path.isAbolute.

Install

Install with npm:

sh
$ npm install --save is-absolute

Originally based on the isAbsolute utility method in express.

Usage

js
var isAbsolute = require('is-absolute');

isAbsolute('a/b/c.js');
//=> 'false'
isAbsolute('/a/b/c.js');
//=> 'true'

Explicitly test windows paths

js
isAbsolute.posix('/foo/bar');
isAbsolute.posix('/user/docs/Letter.txt');
//=> true

isAbsolute.posix('foo/bar');
//=> false

Explicitly test windows paths

js
var isAbsolute = require('is-absolute');

isAbsolute.win32('c:\\');
isAbsolute.win32('//C://user\\docs\\Letter.txt');
isAbsolute.win32('\\\\unc\\share');
isAbsolute.win32('\\\\unc\\share\\foo');
isAbsolute.win32('\\\\unc\\share\\foo\\');
isAbsolute.win32('\\\\unc\\share\\foo\\bar');
isAbsolute.win32('\\\\unc\\share\\foo\\bar\\');
isAbsolute.win32('\\\\unc\\share\\foo\\bar\\baz');
//=> true

isAbsolute.win32('a:foo/a/b/c/d');
