fs.realpath

A backwards-compatible fs.realpath for Node v6 and above

In Node v6, the JavaScript implementation of fs.realpath was replaced with a faster (but less resilient) native implementation. That raises new and platform-specific errors and cannot handle long or excessively symlink-looping paths.

This module handles those cases by detecting the new errors and falling back to the JavaScript implementation. On versions of Node prior to v6, it has no effect.

# USAGE

var rp = require('fs.realpath')
// async version
rp.realpath(someLongAndLoopingPath, function (er, real) {
// the ELOOP was handled, but it was a bit slower
})
// sync version
var real = rp.realpathSync(someLongAndLoopingPath)
// monkeypatch at your own risk!
// This replaces the fs.realpath/fs.realpathSync builtins
rp.monkeypatch()
// un-do the monkeypatching
rp.unmonkeypatch()
