normalize-path NPM version NPM monthly downloads NPM total downloads Linux Build Status

Normalize slashes in a file path to be posix/unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes, unless disabled.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your and support.


Install with npm:

$ npm install --save normalize-path


const normalize = require('normalize-path');

//=> '/foo/bar/baz'

win32 namespaces

//=> '//?/UNC/Server01/user/docs/Letter.txt'

//=> '//./CdRomX'

Consecutive slashes

Condenses multiple consecutive forward slashes (except for leading slashes in win32 namespaces) to a single slash.

//=> './foo/bar/baz'

Trailing slashes

By default trailing slashes are removed. Pass false as the last argument to disable this behavior and keep trailing slashes:

console.log(normalize('foo\\bar\\baz\\', false)); //=> 'foo/bar/baz/'
console.log(normalize('./foo/bar/baz/', false)); //=> './foo/bar/baz/'

Release history


No breaking changes in this release.

  • a check was added to ensure that win32 namespaces are handled properly by win32 path.parse() after a path has been normalized by this library.
  • a minor optimization was made to simplify how the trailing separator was handled
