recursively find the closest package.json
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'))
})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.
