package-root

Is your application or package suffering from relative-path Hell? Do your require statements look like the following?

var config           = require("../../../config"           );
var middleware       = require("../../../lib/middleware"   );
var users_controller = require("../../../controllers/users");

Don't worry -- package-root is here to help! With package-root, you can generate package-relative paths with ease!

var pr = require('package-root');

var config           = pr("config");
var middleware       = pr("lib/middleware");
var users_controller = pr("controllers/users");

There -- I bet you feel better already!

Installation

npm install package-root

Usage

Setup

package-root discovers your package's root by searching for a file named __package_root. For example, let's imagine that our application / package is structured as follows:

.
├── package.json
└── src
    ├── config.json
    ├── controllers
    │   ├── index.js
    │   └── users.js
    └── mw
        ├── auth.js
        └── index.js

Since the package's code lives in the src/ folder, we'll want to place the ___package_root file there. Afterwards, the filesystem will look like this:

.
├── package.json
└── src
    ├── config.json
    ├── controllers
    │   ├── index.js
    │   └── users.js
    ├── mw
    │   ├── auth.js
    │   └── index.js
    └── __package_root

Package-relative require statements

Now that you've planted the __package_root file in the appropriate location, you can perform package-relative requires as follows:

var pr = require('package-root');

// Path is relative to src/
var config = pr("config");

Package-relative path joins

Of course, maybe you just want to obtain the path to some file in your package. You can achieve this by using the join function:

var pr = require('package-root');

// Generate the path to the package's config.json file
var config_path = pr.join("config.json");

Just like path.join, package-root's join function can accept a variable number of arguments:

var users_controller_path = pr.join("controllers", "users.js");

Pretty simple, huh?
