# 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`
1. If one is found, that's the prefix.
2. If none are found, return the original directory we were given
