fast-path

a fast implementation of node's native path

node native path is super slow.

Installation

$ npm install fast-path

APIs

The same as native path APIs

Usage

If you want to replace these APIs in native path:

require('fast-path').replace();  // replace all
require('fast-path').replace('dirname');  // replace `dirname`
require('fast-path').replace(['dirname', 'extname']); // replace `dirname` and `extname`
