resolves

Resolves is a small utility that will resolve the parent folder of the supplied root until the iterator function returns a given value.

Installation

npm install --save resolves

Usage

var resolves = require('resolves');
var path = require('path');
var fs = require('fs');
 
var gitignore = resolves(process.cwd(), function next(dir) {
  var ignore = path.join(dir, '.gitignore');
 
  if (fs.existsSync(ignore)) return fs.readFileSync(ignore, 'utf-8');
});

As seen in the snippet above, the resolve method requires 2 arguments:

• dir The initial directory that we start resolving in.
• iteractor A function that is called for every directory until it returns a value that can be returned. This includes the directory you initially provided.

If the iterator does not find anything, it will keep iterating until it reaches the root folder.
