rwin

Like to keep your requires in the script header?

Tired to load modules that will possibly not been used and overloading your RAM?

Require When It Needeed is a lightweight tool that loads (synchronously) the required module only when and if you really need it!

This Node.js module is under MIT License.

Install :

$ npm install rwin

Usage :

lib = rwin(imports, [dirname]);

Where :

lib : is an object that contains an accessor for each required modules

imports : is an object that contains the accessor name paired with the module path

dirname : is the source path, generally __dirname (useless if You only require installed modules)

Example:

var rwin,
    imports,
    lib;

rwin = require('rwin');

imports = {
    installedModule: 'installed-module',
    uninstalledModule: '/uninstalled-module/path'
};

lib = rwin(imports, __dirname);

// At this point, rwin is the only one loaded module (and its own dependencies)

console.log(lib.installedModule); // loads the module & returns it to the console
