dir-resolve

Purpose

An extension to require.resolve(). Traditionally, require.resolve() calls only work if you're working with files, as opposed to directories. For example:

node_modules/
  module/
    package.json
    test/
    index.js

You could run require.resolve('module') or require.resolve('module/package') and it would return paths to the files you expected. However, if you ran require.resolve('module/test') it would throw an exception. Since require.resolve() is designed to be the underlying mechanism upon which require() works, this is good and expected behavior. After all, what does requiring a directory even mean in node?

That said, I recently have had the desire of being able, to not require() the directories of my dependencies, but to get their locations via require.resolve() at which point this this behavior became a hindrance.

Thus, I have written dir-resolve. Meant to be an extension to require.resolve(), dir-resolve provides all the functionality of require.resolve() but adds the ability to resolve the directories of your dependencies as well.

Installation

npm install dir-resolve

Usage

1var resolve = require('dir-resolve');
2
3//Assuming the example above is at /path
4
5resolve('module/package'); // -> '/path/node_modules/module/package.json'
6
7resolve('module/test'); // -> '/path/node_modules/module/test'

In my testing it is compatible with Windows.

Development

Clone this repo and run npm install to run locally.

To run the tests do npm test or npm test -- --watch.
