find-root

find-root

recursively find the closest package.json

usage

Say you want to check if the directory name of a project matches its module name in package.json:

const path = require('path')
const findRoot = require('find-root')

// from a starting directory, recursively search for the nearest
// directory containing package.json
const root = findRoot('/Users/jsdnxx/Code/find-root/tests')
// => '/Users/jsdnxx/Code/find-root'

const dirname = path.basename(root)
console.log('is it the same?')
console.log(dirname === require(path.join(root, 'package.json')).name)

You can also pass in a custom check function (by default, it checks for the existence of package.json in a directory). In this example, we traverse up to find the root of a git repo:

const fs = require('fs')

const gitRoot = findRoot('/Users/jsdnxx/Code/find-root/tests', function (dir) {
  return fs.existsSync(path.resolve(dir, '.git'))
})

api

findRoot: (startingPath : string, check?: (dir: string) => boolean) => string

Returns the path for the nearest directory to startingPath containing a package.json file, eg /foo/module.

If check is provided, returns the path for the closest parent directory where check returns true.

Throws an error if no package.json is found at any level in the startingPath.

installation

Similar packages

Other packages similar to find-root

pkg-dir

The 'pkg-dir' package provides similar functionality to 'find-root' by finding the closest package.json file in the directory tree. It is a more popular package with additional options and a promise-based API.

app-root-path

The 'app-root-path' package is used to determine the root path of the node application. Unlike 'find-root', which looks for the nearest package.json, 'app-root-path' uses a different heuristic that might be more suitable for certain applications.

root-require

The 'root-require' package allows you to require modules relative to the root of your Node.js project. It is similar to 'find-root' in that it helps with resolving paths in a project, but it is specifically tailored for requiring modules.
