Require ALias

Require path aliasing.

This module allows you to easily move files and directories in your app without having to update many require calls. Instead you update the relevant alias definition.

The paths aliases to be used are defined in require-paths.json. All the paths are relative to the directory this file is in. To configure this directory you must set ral.basePath before your first usage of ral.

For example if require-paths.json is:

{
   "constants" : "lib/constants"
}

Then the base path can be set in the index.js at the root of the project using:

require('ral').basePath = __dirname;

Then the module at lib/constants can be retrieved with:

require('ral')('constants')

If the location of constants changes, only require-paths.json needs to be updated.

A path can be added after the key. For example given constants above:

require('ral')('constants/something')

will give you lib/constants/something.
