decache

In node.js when you require() a module, node stores a cached version of the module, so that all subsequent calls to require() do not have to reload the module from the filesystem.

decache ( Delete Cache ) lets you delete modules from node.js require() cache this is useful when testing your modules/projects.

Why?

When testing our modules we often need to re-require the module being tested. This makes it easy.

What?

An easy way to delete a cached module.

How? (usage)

### install

Install the module from npm:

npm install decache --save-dev

Use it in your code:

// require the decache module:
var decache = require('decache');

// require a module that you wrote"
var mymod = require('./mymodule.js');

// use your module the way you need to:
console.log(mymod.count()); // 0   (the initial state for our counter is zero)
console.log(mymod.incrementRunCount()); // 1

// delete the cached module:
decache('./mymodule.js');

//
mymod = require('./mymodule.js'); // fresh start
console.log(mymod.count()); // 0   (back to initial state ... zero)

Modules other than .js, like for example, .jsx, are supported as well.
