find-npm-prefix

Find the npm project directory associated with for a given directory

USAGE

const findPrefix = require('find-npm-prefix')

findPrefix(process.cwd).then(prefix => {
  …
})

findPrefix(dir) → Promise(prefix)

This computes the npm prefix, that is, the directory that npm adds and removes modules from for a given path.

It takes a directory as an argument and returns a promise of the associated prefix directory.

Algorithm

  1. If the directory is a node_modules folder, scan up the tree till you find a non-node_modules directory and return that.
  2. Else, look for the first parent directory that contains a node_modules or a package.json
  3. If one is found, that's the prefix.
  4. If none are found, return the original directory we were given
