Pkgresolve NPM

pkgresolve

Resolve a dependency from within the context of another package.

Useful for hacks, monkeypatching or wrappers that require manipulation of the exact dependency that would be loaded by a package.

Installation

npm install --save pkgresolve

Example

var resolve = require('pkgresolve')

// Resolve 'through' from locally installed 'tape'
resolve('through').from('tape', function(err, pkgPath) {
  // pkgPath - path to through or null
})

// Resolve 'npmconf' from globally installed 'npm'
resolve('npmconf').fromGlobal('npm', function(err, pkgPath) {
  // pkgPath - path to npmconf or null
})

CLI

# Resolve 'through' from locally installed 'tape'
pkgresolve tape through

# Resolve 'npmconf' from globally installed 'npm'
pkgresolve --global npm npmconf

Why not `require('parent/node_modules/child')`?

Due to deduplication, child is not guaranteed to exist at that location. You don't even need to call npm dedupe for this to happen – npm will not install something that is already installed in the hierarchy. pkgresolve is a more robust method.
