freshy v1.0.4

freshy

An (admittedly naïve) node module (un|re)loader/refreshener.

API

unload(module)

• module (String) - the module to unload

Completely unload a node module from the cache. Returns true if the module was present in the cache, false if not.

var minimist = require('minimist'),
    freshy = require('freshy');

freshy.unload('minimist'); // true

reload(module)

• module (String) - the module to reload

Completely unload and reload a given module in place, leaving the new copy in the cache. Returns reloaded module.

var minimist = require('minimist'),
    freshy = require('freshy');

var fresh = freshy.reload('minimist');
console.log(minimist === fresh); // false

freshy(module, callback)

• module (String) - the module for which to fetch a fresh instance
• callback (function, optional) - A function called while the fresh module is the one in cache

Get a fresh instance of a module without disturbing the cached copy. Returns the fresh module instance.

var minimist = require('minimist'),
    freshy = require('freshy');

var fresh = freshy.freshy('minimist');
console.log(minimist === fresh); // false

var mini = require('minimist');
console.log(minimist === mini); // true

And to get a consistent require of modules that require each other, you can use the callback style:

var minimist = require('minimist'),
    freshy = require('freshy');

var alsofresh;
var fresh = freshy.freshy('minimist', function (fresh) {
    alsofresh = require('minimist');

    console.log(fresh === alsofresh); // true
});
console.log(minimist === fresh); // false
console.log(fresh == alsofresh); // true

var mini = require('minimist');
console.log(minimist === mini); // true

This is useful for modules that alter other modules you require. dustjs-linkedin and dustjs-helpers is an example of this.
