Whenever

Lazy loading of modules in Node.js. If speed's your thing, this might come in handy.

Example

Requiring a relative module on the same path.

// foo.js

module.exports.hello = function() {
  console.log('Hello world!');
}

// main.js

var whenever = require('whenever');
var modules  = whenever('foo', __dirname);

console.log(modules); // {} -> not loaded yet.    
modules.foo.hello(); // requires and then prints 'Hello world';

You can also pass an array and pre-load more than one module.

var modules  = whenever(['foo', 'bar'], __dirname);

Ok, now let's get fancier. Let's lazy-load all modules in a given path.

var modules = whenever('*', __dirname + '/lib');
modules.foo.hello();
modules.bar.bye();

If you need to use a npm/core module, you can also have it. Just don't pass the path argument.

var modules = whenever(['async', 'fs']);

modules.fs.readFile('/etc/passwd', function(err, res) {
  // continue hacking the gibson.
})

Install

$ npm install whenever --save
